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.
