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.
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.
The number of charge cycles a lead-acid battery can undergo depends on the type of battery and the quality of the battery. Generally, a well-maintained lead-acid battery can undergo around 500 to 1500 charge cycles. What maintenance practices extend the life of a lead acid battery?
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.
Full charging helps prevent sulfation, a condition in which lead sulfate crystals form on the plates, reducing battery capacity. Check the load periodically to make sure they are not completely discharged. Lead-acid batteries can lose their charge over time, even when not in use.
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.
