    FAQs about How long can a lead-acid battery be stored before being fully charged

    How long can a lead acid battery last?

    Charge a lead acid battery before storing. Lead acid batteries can be stored for up to 2 years. It is generally advisable to periodically monitor the battery voltage and charge it when it falls below 70 percent state-of-charge (SoC); however, lead batteries typically have brand specific readings.

    How long can a lead-acid battery be stored?

    A lead-acid battery can be stored for up to two years. However, it is important to note that all batteries gradually self-discharge over time, which is known as 'calendar fade.'

    What temperature should a lead acid battery be stored?

    The recommended storage temperature for most batteries is 15°C (59°F); the extreme allowable temperature is –40°C to 50°C (–40°C to 122°F) for most chemistries. You can store a sealed lead acid battery for up to 2 years.
