6 Frequently Asked Questions about “How long can a lead-acid battery be stored without charging ”

How long can a lead acid battery last?

Besides, inside the battery there is basically an acid (the density might be lower compared to a bleacher but, still an acid). A lead acid battery can be stored for at least 2 years with no electrical operation. But if you worry, you should: And, if possible, recharge it periodically (3 to 6 months).

How often should a sealed lead acid battery be charged?

Sealed Lead Acid batteries should be charged at least every 6 – 9 months. A sealed lead acid battery generally discharges 3% every month. If a SLA battery is allowed to discharge to a certain point, you may end up with sulfation and render your battery useless, never getting the intended life span out of the battery.

How often should a lead acid battery be recharged?

Sealed lead acid batteries need to be kept above 70% State of Charge (SoC). If you are storing your batteries at the ideal temperature and humidity levels then a general rule of thumb would be to recharge the batteries every six months. However if you are not sure then you can check the voltage as follows:

What temperature should a lead acid battery be stored?

Exposure to high temperatures and humidity can accelerate the battery's self-discharge rate and shorten its lifespan. The ideal storage temperature for lead acid batteries is between 50°F (10°C) and 80°F (27°C). Avoid storing the battery in extreme temperatures, as this can damage the battery and reduce its capacity.

How do you store a lead acid battery?

When storing your battery, make sure it is clean and dry, and kept in a cool, dry place with good ventilation. Exposure to high temperatures and humidity can accelerate the battery's self-discharge rate and shorten its lifespan. The ideal storage temperature for lead acid batteries is between 50°F (10°C) and 80°F (27°C).

Can a lead acid battery be left uncharged?

Higher temperatures significantly prolong battery life. You can leave a lead acid battery uncharged indefinitely. Double the charging voltage will double the battery lifespan. Using a battery regularly is more harmful than letting it sit unused. Lead acid batteries should be fully discharged before recharging is a common myth.
