Overcharging is a major cause of shedding. When a battery is overcharged, excessive current can cause the plates to heat up, leading to faster degradation of the active material. Deep discharges and frequent cycling can also accelerate shedding, especially when the battery is subjected to high loads or left discharged for long periods.
What causes a battery to short?
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.
