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.
Lead-Acid batteries can indeed be charged after being dead. Commonly used in vehicles, these batteries operate on a lead-dioxide and sponge lead chemistry. They are robust and suitable for high drain applications. However, if allowed to fully discharge repeatedly, their performance may degrade significantly.
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.
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.
Myth: Lead acid batteries can have a memory effect so you should always discharge them completely before recharging. Fact: Lead acid battery design and chemistry does not support any type of memory effect.
This occurs because of a process called sulfation. When a lead acid battery discharges, small sulfate crystals made of lead and sulfur form on the battery's plates. This is a natural part of the discharge process, which becomes reversed when the battery is recharged.
