What are the factors that are unfavorable to lead-acid batteries?
15 Apr 2023

There are many factors that are unfavorable to the battery, mainly in the charging and discharging phase.


(1). The "second super" discharge stage is mainly the discharge current overvalue, that is, the discharge exceeds the allowable current value for a long time; the second problem of discharge is over-discharge, that is, exceeding the allowable discharge capacity of the battery, which is called "second super", which is very harmful to battery life. .


(2). There are "two passes" and "two owes" in the charging stage of "two passes" and "two owes".


"Two passes": one pass is overcharging; the other pass is that the lead-acid battery is stored for too long and is not regularly replenished.


"Two debts": one is that the lead-acid battery is undercharged, the battery is often not fully charged, and the plate cannot be restored in time after vulcanization, which is extremely taboo for the lead-acid battery; the other is the gap between the cells in the battery pack. The lack of balance causes the gap between the discharge level and charge level of each single battery in a group of batteries to widen, and the undercharged ones will be undercharged, and the overdischarged ones will be overdischarged. Affect the life of the whole battery pack, but also increase the economic expenditure.


"Two passes" and "two owes" are the enemies of batteries and should not be underestimated. But the "two faults" and "two owes" are caused by people themselves, and the problems are more complicated. The timely detection of the cause of battery failure, etc., they are interrelated.


High temperature, when the temperature exceeds the nominal temperature, the service life of the battery will be doubled for every 10°C increase in temperature.
