Lead-acid storage battery will lose part of its capacity due to self-discharge. Therefore, before lead-acid battery is installed and put into use, the remaining capacity of the battery should be judged according to the battery's open circuit voltage, and then different methods should be used for supplementary charge for the battery.
Shedded Material Accumulation: As mentioned earlier, active material that sheds from the plates can accumulate at the bottom of the battery case. If enough material builds up, it can form a conductive bridge between the plates, leading to an internal short. Detecting internal shorts early is crucial for preventing extensive damage to the battery.
Lead-acid batteries, widely used across industries for energy storage, face several common issues that can undermine their efficiency and shorten their lifespan. Among the most critical problems are corrosion, shedding of active materials, and internal shorts.
Here are a few signs that may indicate the presence of an internal short: Rapid Self-Discharge: If the battery discharges unusually fast, even when not in use, it could indicate an internal short. This self-discharge occurs because the internal short circuit is draining the battery's energy continuously.
