Battery formation process irreversible sulfation main reasons include

Frequent deep discharge and over-discharge, no timely charge or charge less; deficit in the long-term status of the battery power left unused that poor memory; battery pack Cargo trikes inconsistent battery performance, there are differences too much behind the battery; performance of a battery pack a battery's capacity is significantly lower than the other battery, causing the entire battery voltage drops, the first to be fully behind the battery because the remaining battery charge and the Folding electric bikes form still charging overcharge, discharge the battery behind because of the first to be vented to form over-discharge, resulting in further exacerbate sulfate, making more serious degree of backwardness, creating a vicious cycle; electrolyte density is too large; battery ambient temperature changes.
