AI Customer ServiceMyth: Lead acid batteries can have a memory effect so you should always discharge them completely before recharging. Fact: Lead acid battery design and chemistry does not support
AI Customer ServiceFor example, a lead-acid battery loses about 5% of its charge per month, while a Lithium-ion battery loses around 2%. This means if you leave a fully charged battery unused for a while,
AI Customer ServiceSelf-discharge of batteries is a natural, but nevertheless quite unwelcome phenomenon. Because it is driven in its various forms by the same thermodynamic forces as
AI Customer ServiceA lead acid battery left in storage at moderate temperatures has an estimated self-discharge rate of 5% per month. This rate increases as temperatures rise and as the risk of sulfation goes up.
AI Customer ServiceA fully charged lead acid battery typically measures between 12.6 and 12.8 volts, while a 50% SOC corresponds to around 12.0 volts. This means that the battery is not being charged or discharged, and the voltage

AI Customer ServiceA parasitic load or high self-discharge prevents voltage recovery. During a battery discharge test (lead acid 12v 190amp) 1 battery in a string of 40 has deteriorated so
AI Customer ServiceSince that is no longer an issue (and never was an issue with lead acid batteries) there is not a need to fully discharge. By discharging a lead acid battery to below the manufacturer’s stated end of life discharge voltage you are allowing the polarity of some of the weaker cells to become reversed.
All batteries experience some amount of self-discharge, yes. But, the rate of discharge for lead acid batteries depends on a few key factors. Temperature: The warmer the environment while a battery is in storage, the faster the rate of self-discharge.
A lead acid battery left in storage at moderate temperatures has an estimated self-discharge rate of 5% per month. This rate increases as temperatures rise and as the risk of sulfation goes up. Sulfating: This is a buildup of lead sulfate crystals and it occurs when a lead acid battery is left sitting without a full charge.
Figure 4 : Chemical Action During Discharge When a lead-acid battery is discharged, the electrolyte divides into H 2 and SO 4 combine with some of the oxygen that is formed on the positive plate to produce water (H 2 O), and thereby reduces the amount of acid in the electrolyte.
Myth: The worst thing you can do is overcharge a lead acid battery. Fact: The worst thing you can do is under-charge a lead acid battery. Regularly under-charging a battery will result in sulfation with permanent loss of capacity and plate corrosion rates upwards of 25x normal.
The sulfate (SO 4) combines with the lead (Pb) of both plates, forming lead sulphate (PbSO 4), as shown in Equation. As a lead-acid battery is charged in the reverse direction, the action described in the discharge is reversed. The lead sulphate (PbSO 4) is driven out and back into the electrolyte (H 2 SO 4).
