All lead acid batteries, including AGM, want to be at 100% charge 100% of the time. Anything less than that ages the battery. Now, a battery you can''t use at all is kind of useless, so they can be discharged to a maximum of 50% of their capacity, but once there they have to be gotten back up to 100% as soon as possible.. Otherwise, a process known as sulfation immediately starts to

Myth: The worst thing you can do is overcharge a lead acid battery. Fact: The worst thing you can do is under-charge a lead acid battery. Regularly under-charging a battery will result in sulfation with permanent loss of capacity and plate corrosion rates upwards of 25x normal.
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.
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.
However, most chargers sold today are “smart” chargers and will shut off after the battery is fully charged. Myth: Any charger should work perfectly okay with any type of lead acid battery. Fact: There are many different technologies used in lead acid batteries.
In both flooded lead acid and absorbent glass mat batteries the buckling can cause the active paste that is applied to the plates to shed off, reducing the ability of the plates to discharge and recharge. Acid stratification occurs in flooded lead acid batteries which are never fully recharged.
