Vary from motorcycle batteries and car batteries
Motorcycle batteries serve the same purpose as the car batteries although there are some differences from them. They both provide energy to start the vehicle engine, so they are all called starting battery. And both of types of batteries need constant recharging from the charger system, just only the motorcycle battery doses not require nearly as much power to keep it charged. This time, I will say something about what is the difference between them.
Just as its name implies, motorcycle batteries provide energy to start motorcycle, car batteries provide energy to start car. Just only a motorcycle battery is smaller than a car battery, either case or capacity, which the capacity is lower than motorcycle. A motorcycle battery has to fit into a smaller place in a smaller vehicle. It also does not need to provide electrical power for many accessories such as DVD, navigation radar, air conditioning, cigarette lighter of car and more. The motorcycle sized battery will range from about 6 amp hours to 12 amp hours of CCA, but car battery start at about 12 amp hours all the time.
A motorcycle battery is cheaper than a car battery. Items of this difference are widely, many factors can affect it, which are smaller size, small power lighter, contains less acid, manufacture process, package, lesser of weight contribute to the lower delivery cost and so on. All of these factors can affect the lower cost.
In fact, some of the differences between them, the most important is capacity. Motorcycle battery capacity maximum reach 30AH, which is in 2.3AH-30AH. Car battery capacity maximum reach 220AH and the capacity is more widely.

Easily Do Automobile Battery Maintenance
As you know, there are many electric equipments in the car, and in addition to the electric generator, automobile battery is the auxiliary power supply. The automobile battery plays an important role on the car use. If it can't supply the power normally, the use of electric generator and electrical system will also have problems. Hence the car owners need to maintain in the daily use so as to avoid it not get started or stop suddenly in the halfway. In fact, it is easy to take care of automobile battery. The car owners just spend one or two minutes to maintain the automobile battery when you check the electric generator every time.
Leoch Battery will introduce you some maintenance tips of automobile batteries.
1. Often clean automobile battery. If there are no white acid etching powder, the life will be longer. You just use the wet cloth to clean the external of automobile battery and remove the dust, greasy dirt, white powder etc, which will cause leakage of electricity.
2. Examine the level. Open the cover of automobile battery, and then you can find whether the level is normal. In general, there is lower lane markings (LLM) and upper lane markings (ULM) in the side of battery for your reference. If the level is lower than the lower lane markings, you must add distilled water. But if there is no distilled water in hand, you can use the filterable tap water for emergency instead. Don't add too much, and just reach the middle between lower lane markings and upper lane markings.
3. Check whether automobile battery can be charged normally. If you use the three-purpose galvanometer to measure the voltage before starting the engine, it is normal just over 13V. If the charging voltage is too low, you need to ask the repairer to check the charging system. If you don't have the galvanometer, you can use ocular estimate: When you start the engine, open the cover and watch whether there is bubble among each grid. In the normal condition, there must be most bubbles to surface. But if nothing is found, the charging system might have some problems. Please note: In this test, it will produce hydrogen, so you must not smoke in case of exploding.

The status of using and maintenance of ups battery.
Generally, the ups battery’s design life is five years. However, some batteries can be used 6-7 years, others begin to have problems when use one year. How could this be? The main reason is product quality and daily maintenance. So choose better ups battery and maintenance it are important to the battery service life.
The method of maintain ups battery is similar to maintain low pressure system battery. When bring in new batteries, to acceptance of work, the depth of discharge. When the new battery put into use, the work condition is required to keep in proper temperature. Have regular time checking the terminal voltage is normal. When the voltage different is over, going average charge. Have regular the battery capacity test or exploratory depth of discharge, in order to check the performance of the battery pack and keep the battery activity.
But in the virtually application, due to various constraints, very few people maintain ups battery exactly following above methods. Firstly, acceptance of new batteries, as a long time, nor convenient tools are available, a lot of people don’t acceptance of work put batteries into use directly. According to statistics, in mainland china, over 95% ups batteries lack of necessary maintenance, which lay hidden to Ups power supply failure for the future. Secondly, when new batteries put into use, because of ups batteries are installed in cabinet, measuring and divorcing is inconvenience, few measuring voltage, regular depth of discharge is impossible. According to existing conditions (98% of ups batteries are not installed monitoring equipment), the maintenance personnel can carried out only from time to time, turn off electricity to ups batteries discharge for a while, only excite batteries to keep battery packs activity. But some important data is unknown such as batteries performance and the rest of capacity, etc.

The Purpose of Automobile Battery
The automobile battery is used to supply power to the car start, which makes the electric machine run, and deliver the power source to the ignite and lighting. It is also called SLI battery, (starting, lighting, and ignition). The automobile battery supply power to other equipments, such as stereo, whistling wiper, etc.
Due to the main purpose of car start, it needs large current to the engine, and the larger current is required to start the engine in the winter. In general the starting current is 5C20, some are 10C20.
When the car is running normally, the engine is charging the automobile battery. The voltage regulator is generally installed on the car, so the battery charging will be stopped if it reaches a certain degree. For 12V automobile battery, the voltage is limited below 14.4V.
With the improvement of cars, there are more demands for the automobile batteries, such as working in the hot environment, good low temperature fast discharging performance (CCA), lightweight, small in size, high capacity, superior charging performance in the high speed running, maintenance-free without adding any water, and less maintenance battery, etc.
As the demand of cars is increased due to the modern industrial economy, automobile batteries have a bright future. Besides, the quantity demanded of maintenance-free battery is still on the increase.

How to prevent the motorcycle be stolen
Yesterday, I went to a friend’s home to have a supper. Let the motorcycle park in the downstairs. After supper, I was ready to back and found a plastic on the ground. The plastic was used to protect the motorcycle battery. Then I thought the battery was stolen away and finally looked at it carefully. It was still here. Maybe the manufacturer considering the motorcycle battery is easy to be stolen away, which was fitted by a screw. So the stealer couldn’t get it. Really angry about this phenomenon!
At present I have a method to avoid the motorcycle battery to be stolen. Take down the original plastic and choose a bar iron surround the battery. And then welded two ends but not welded dead, and add a lock to lock it on motorcycle. Anyone can't steal the battery unless he moves the whole motorcycle frame. You can consider to do like me that only cost $5. Police also remind motorcycle owners:
1.When you go out, the motorcycle should be placed in your sight or park it in place which has administrator.
2.Parked the motorcycle in the hall and close the door.
3.Install anti-theft lock and burglar alarm for the motorcycle. Select the best performance of anti-theft lock, which is similar to the type of "U" lock.
4. Don't lent it to other at random to avoid others match the keys.
5.Once your motorcycle is stolen, call the police in time to crack down criminal rapidly and minimize the loss.
If you discover any suspicious, please call the police firstly.

How to Charge a Lead Acid Battery with Three Stages
As you know, the lead acid battery often self discharge automatically, special not in use. And if you overcharge it, the performance might be not as good as it should be before. Hence, giving it a right charge is also very important for its lifespan. There are three stages charging that you can use to charge your lead acid battery.
Bulk Charge - Current is sent to batteries at the maximum safe rate they will accept until voltage rises to near (80%-90%) full charge level. Voltages at this stage typically range from 10.5 volts to 15volts. There is no “current” voltage for bulk charging, but there may be limits on the maximum current that the battery and/or wiring can take.
Absorption Charge – Voltage remains constant and current gradually tapers off as internal resistance increases during charging. It is during this stage that the charger puts out maximum voltage. Voltages at this stage are typically around 14.2 to 15.5 volts.
Float Charge – After batteries reach full charge, charging voltage is reduced to a lower level (typically 12.8-13.2) to reduce gassing and prolong battery life. This is often referred to as a maintenance or trickle charge, since it’s main purpose is to keep an already charged battery from discharging. Note that for long term float service, such as backup power systems that are seldom discharged, the float voltage should be around 13.02 to 13.20 volts.
Most garage and consumer (automotive) type battery chargers are bulk charge only, and have little (if any) voltage regulation. They are fine for a quick boost to low batteries, but not to leave on for long periods. Among the regulated chargers, there are the voltage regulated ones. If there are set to the correct voltages for your batteries, they will keep the batteries charged without damage.

Are you ready to ride a motorcycle to TRIP?
People dream of riding motorcycle to trip. It is so special about feeling the wind and seeing the open vision. However, without ready, you may not make it to your destination and affect the trip mood. So making sure your motorcycle battery is in good condition is very important.
Checking the electrolyte is between in standard line. Because of the acid is form of corrosive poison and can produce toxic gases, you had better buy a maintenance-free motorcycle battery, which is completely sealed and you needn’t maintain it. Of course, there is also a conventional motorcycle battery that you must add distilled water occasionally. But it will bring inconvenience to your trip because you may often worry about maintenance. In my opinion, having fun on your trip is primary. Don’t save money to affect trip mood. Purchase maintenance free battery decisively.
Check your motorcycle power source and top it off to a full charge during it may be low. If you are ready for a long travel, it is important to be prepared for tools such as jumper cables and a battery charger. Because of extreme cold or heat can drain the motorcycle battery faster, so if you are traveling in that weather conditions, you will need charging more often. Bring your charger to travel with you, it will help you. The charger takes up very little room, which can be plugged into any outlet available.
Wish you enjoy your travel. If you like, you can share your feeling with me after back.

Four Simple Maintenance Tips of UPS Battery
UPS batteries have a finite operating life which is determined by factors such as the ambient temperature and the number of charge/discharge cycles. Regular maintenance is critical to ensure the battery working life is optimized and weak or faulty battery blocks are detected. There are four simple maintenance tips of ups battery to help you extend the service lifespan.
Tip1 UPS manufacturers often propose a regular maintenance schedule to maintain performance. The battery requires special attention, as UPS failure is often caused by a battery-related problem and not by the UPS's electronics.
Tip2 Make sure that ventilation keeps the equipment at the operating temperature range specified by the manufacturer. Install dedicated air conditioning if necessary.
Tip3 Periodically compare the load and type of load with the UPS specification to make sure the system is still able to meet changes in demand.
Tip4 Standby (offline) UPSs have an automated switching system that brings the UPS online. Periodically test the switching system.
If you want to know more about ups battery, you can just visit Leoch International, which is an excellent manufacturer of lead acid battery.

Failure Analysis and Processing of Lead Acid Battery (2) – Float Charging Voltage is low
Float charging, one working way of lead acid battery pack, is to connect the battery pack and power line in parallel to load circuit. The constant charging voltage is a little higher than its open-circuit voltage and it depends on a small electric charge delivered by power line to compensate self discharge of the storage battery pack so as to keep it long time in the full charge standby mode then not over charge. In the long-time usage of lead acid battery, it might happen that the float charging is low. Why cause that? Maybe the usage is not proper or the quality has something wrong.
The long-time floating charging use or not effective maintenance causes the floating charging voltage low of the single or more batteries. The single battery is lower than 2.20V. Confirmatory analysis showed that new batteries before they go out experienced the capacity, float charging, open-circuit voltage, internal resistance etc matching sets, so the discreteness of new batteries’ float charging is small. With the continuous use, the slight difference of the lead acid battery that must exist in manufacturing process will gradually be expanded, such as the difference of open valve voltage, self discharge, and plates. The open valve voltage’s difference will cause the different water loss. The rate of sulfuric acid electrolyte of battery that lost more water will go up, and then increase the open-circuit voltage, as well as the float charging voltage. When the total voltage is not changed, it will make the float charging voltage of other batteries in series decrease, and finally lead to the voltage fall behind. The voltage of lead acid battery with large self discharge is easily to fall behind in the long-time float charging process. When the plates happen to soften, the active material dropped out will block the micro holes of the plates, causing the capacity falling behind, and finally the float charging is low. The proper processing method is to start the temperature compensation and equalized charging functions, and setup average charge every three months.
Completely discharging and not getting charged in time, or over discharging, or long-time lack of charging, all can cause the single or more batteries’ float charging voltage low. The voltage of single battery is lower than 2.18V. You can use equalized charge for the battery pack. If it can’t fix the voltage of the disabled single battery, you’d better recover it separately. If the condition permission, you can use the low current to charge and discharge for 1 to 3 recycles, and then the disabled batteries’ voltage and capacity will get a good recovery. But for the serious sulfation battery, you have to replace it.
If the float charging voltage is low or the setting value is lower than 10%, such as lower than 2.0V, then the battery might be micro short circuit or short circuit. You can do the electric discharge validation, because the short-circuit battery can’t afford the discharge test. If the discharge voltage goes down fast, or down quickly to 0V, then you have to replace the disabled battery. If it is normal, you can use the above methods to recover it.

Failure Analysis and Processing of Lead Acid Battery
Insufficient capacity, also called short discharging time, is one type of frequent failure analysis of lead acid battery in the market. The reason why lead to the lead acid battery discharging for a short time is not only the improper usage, but the quality of the battery.
Lead acid battery uses the reversible chemical reaction to store electrical energy. The condition of usage has a big impact on the capacity, so the good using condition is very important. There are three reasons to easily cause the battery capacity decline. First, the frequent power failures make the battery lack of long-time charging, and then cause the plates sulfation and capacity decline. Second, when the battery finishes discharging, it doesn’t get the voltage protection or the device control failure, which will make the battery over discharge. It will make the plates sulfation and the voltage low, then capacity decline. Third, when the battery discharges fully and is not charged in time for a long time, it also makes the capacity decline.
If these happen to your battery, you can adopt the low current to recover the capacity by charging and discharging recycle. For the moderate sulfation battery, you can recover most of capacity, while the serious one, you can only recover a little, even nothing. When the recovered capacity is 80% lower than the rated capacity, you have to replace the battery. Of course, you can also use the accumulator or activating agent to fix the lead acid battery.
However, the improper usage of lead acid battery also makes it insufficient capacity. If the test ambient temperature is a little low, the actual capacity will be lower than the rated capacity. If the float charging voltage is very low, it will cause the battery be used not in the full capacity. Beside, if you use it for long time and don’t maintain it, this will make the each cell or cells battery capacity fall behind.
In fact, the quality of lead acid battery is also one reason to cause the capacity not enough. When discharging, the voltage declines quickly, then it means that the battery is short circuit; but if the voltage declines very fast even the battery can’t discharge, the battery is open circuit. If the two conditions happen, it is in charge of the lead acid battery manufacturer replacing the monomer failure battery for free.

The Valve of GEL Battery
Gel battery is different from AGM VRLA battery, which uses the gel electrolyte, allowing you to mount the battery in any direction, even upside down, giving more flexibility to installers.
A gel cell is a “recombinant” battery. This means that the oxygen that is normally produced on the positive plate in all lead acid batteries recombines with the hydrogen given off by the negative plate. The “recombination” of hydrogen and oxygen produces water (H which replaces the moisture in the battery. Therefore, the battery is maintenance-free, as it never needs watering.
The oxygen is trapped in the cell by special pressurized sealing vents. It travels to the negative plate through tiny fissures or cracks in the gelled electrolyte.
The sealing vent is critical to the performance of the gel cell. The cell must maintain a positive internal pressure. Otherwise the recombination of the gasses will not take place, and the cell will dry out and not perform.
In addition, the valve must safely release any excess pressure that may be produced during overcharging. Otherwise the cell would be irreparably damaged.
It’s important to note that a gel cell must never be opened once it leaves the factory. If opened, the cell loses its pressure, and the outside air will “poison” the plates and cause an imbalance that destroys the recombination chemistry.

Four Simply Steps to Charge a GEL Battery
Most batteries available in the market are lithium ion or lead acid battery, but some are gel battery with gel electrolyte, which allow you to mount the battery in any direction, even upside down, giving more flexibility to installers. Different from other batteries, this gel battery can be normal charged by just inserting the charger between the battery and power source. But how should I charge a gel battery? Just read this article and the author will tell you in detail.
First be ready for a battery charger near the gel battery. In general, gel batteries should be charged with a gel battery charger, but if you don’t have one, you can use a lead acid charger, as long as it has variable charger settings.
Next, put the battery on a battery tray on a stable work surface. Gel batteries are fairly heavy, so you want to make sure the work surface doesn’t collapse. Of course, you need to carry this to the battery tray if you can. If not, don’t do that you can’t, and ask some one for help.
Then start to connect the battery and the charger. Attach the metal spring-loaded clamp on the end of the charger’s red cable to the positive terminal of the gel battery. The positive terminal has a “+” marked on or near the terminal. Then attach the clamp on the end of the charger’s black cable to negative terminal of the battery. The negative terminal has a “- “marked on or near the terminal. Don’t mix the connection. The red cable attach the “+” while the black cable attach the “-“.
Plug the charger into an electrical outlet. Check that the charge limit illuminates on the charger, which confirms that the gel battery is being charged. A gel battery charger regulates the charging rate and turns off automatically once the battery fully charged. It is well known that it is usual for a battery to get warm during a charge, but if you find it’s getting hot to the touch, please turn off the charger and let the battery cool before continuing.
Finally, remove the clamps from the battery terminals when it is full charged. Leave the gel battery for a few hours before using it, which allows it time to settle the charge it’s received. A perfect charge is over. Just use it as usual. Please note: don’t attach the red cable to “-“and black cable to “+”. At this moment, maybe it won’t damage it, but it must shorten the lifespan of the gel battery. So don’t make this mistake when you are ready to charge the gel battery.
