6 FAQs about [The lead-acid battery has run out of power after being stored for half a year ]

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.

Can lead acid batteries be stored outside?

Nowadays modern plastics are impervious to acid so there is no risk of this happening. Myth: It is okay to store lead acid batteries anywhere inside or outside. Fact: It is good to store lead acid batteries in cool places because the self-discharge is lower but be careful not to freeze the battery.

Do lead acid batteries degrade over time?

All rechargeable batteries degrade over time. Lead acid and sealed lead acid batteries are no exception. The question is, what exactly happens that causes lead acid batteries to die? This article assumes you have an understanding of the internal structure and make up of lead acid batteries.

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 happens if a lead acid battery is flooded?

If lead acid batteries are cycled too deeply their plates can deform. Starter batteries are not meant to fall below 70% state of charge and deep cycle units can be at risk if they are regularly discharged to below 50%. In flooded lead acid batteries this can cause plates to touch each other and lead to an electrical short.

What causes a lead acid battery to fail?

If you are not familiar with lead acid batteries, see our article What is a lead acid battery. Ironically one of the most common reasons for battery failure is not an actual failure of the battery itself, it is people thinking the battery is dead.
