Whereas a lead acid battery being stored at 65℉ will only discharge at a rate of approximately 3% per month. Length of Storage: The amount of time a battery spends in storage will also lead to self-discharge. A lead acid battery left in storage at moderate temperatures has an estimated self-discharge rate of 5% per month.
Thermal events in lead-acid batteries during their operation play an important role; they affect not only the reaction rate of ongoing electrochemical reactions, but also the rate of discharge and self-discharge, length of service life and, in critical cases, can even cause a fatal failure of the battery, known as “thermal runaway.” This contribution discusses the parameters
A lead-acid battery loses power mainly because of its self-discharge rate, which is between 3% and 20% each month. Its typical lifespan is about 350 cycles.
