A lead acid battery has a limited shelf life, even if it is not being used. The shelf life of a Sealed Lead Acid (SLA) battery is about a year at full capacity when stored at room temperature without charging. Flooded lead acid batteries have
A practical understanding of lead acid batteries
However, if the battery setup is only meant for emergency power and thus only expected to operate a few times a year, discharging a lead acid battery to 80% of capacity is not a big deal. There is no need to add extra
Deep Cycle Battery Voltage Chart
For example, a 12V lead-acid deep cycle battery at 100% capacity will have a voltage of around 12.7V, while a battery at 50% capacity will have a voltage of around 12.2V.
Why Your Sealed Lead Acid Battery Won''t Hold a Charge
One common reason why a sealed lead acid battery might not hold a charge is due to a lack of maintenance. If the battery is not charged properly, or is left unused for long
Why don''t lead acid batteries last forever?
Acid stratification has become a more popular reason for battery failure in recent times due to more electrical devices being added to cars and other road transport. It occurs

6 FAQs about [Lead-acid battery that has not been charged for half a year]
Why does a sealed lead acid battery not hold a charge?
One common reason why a sealed lead acid battery might not hold a charge is due to a lack of maintenance. If the battery is not charged properly, or is left unused for long periods of time, it can become depleted and unable to hold a charge. Additionally, if the battery is overcharged, it can become damaged and unable to hold a charge as well.
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.
What happens when a lead acid battery is charged?
When a sealed lead acid battery is charged, electrical energy is converted into chemical energy, which is stored in the battery. The lead plates and lead oxide plates react with the electrolyte to form lead sulfate and water. When the battery is discharged, the lead sulfate and water react to form lead, lead oxide, and sulfuric acid.
Can I recharge a dead sealed lead acid battery?
Can I recharge a completely dead sealed lead acid battery? Sealed Lead Acid batteries fall under the category of rechargeable batteries and if they are ignored, not charged after use, not charged properly or have reached the end of their intended life span, they are done.
Should a lead acid battery be fused?
Personally, I always make sure that anything connected to a lead acid battery is properly fused. The common rule of thumb is that a lead acid battery should not be discharged below 50% of capacity, or ideally not beyond 70% of capacity. This is because lead acid batteries age / wear out faster if you deep discharge them.
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.
