6 FAQs about [Lead-acid battery self-discharges too quickly]
Do lead acid batteries self-discharge?
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.
How much does a lead acid battery discharge per month?
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.
What happens if a lead acid battery is left uncharged?
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.
How fast does a lead acid battery self-discharge?
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. For example, a battery being stored at an average temperature of 80℉ will discharge at a rate of 4% per week.
Do lead acid batteries need to be fully discharged?
Since 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.
How long can a lead acid battery last without charging?
Figure 6 illustrates the self-discharge of a lead acid battery at different ambient temperatures At a room temperature of 20°C (68°F), the self-discharge is roughly 3% per month and the battery can theoretically be stored of 12 months without recharge.
