Test show that a heathy lead acid battery can be charged at up to 1.5C as long as the current is moderated towards a full charge when the battery reaches about 2.3V/cell (14.0V with 6 cells). Charge acceptance is highest when SoC is low and diminishes as the battery fills.
Regularly charge your lead acid battery before it reaches a critically low state of charge. Deep discharges can affect the battery’s capacity and overall lifespan. Charging a lead acid battery correctly is crucial to ensuring its optimal performance and longevity.
Lead acid charging uses a voltage-based algorithm that is similar to lithium-ion. The charge time of a sealed lead acid battery is 12–16 hours, up to 36–48 hours for large stationary batteries.
The recommended charging voltage for a lead acid battery is around 2.3 to 2.4 volts per cell, or about 13.8 to 14.4 volts for a 12-volt battery. It’s important to avoid overcharging the battery as it can lead to electrolyte loss and damage to the battery. Can I use a regular car battery charger to charge a lead acid battery?
The charge time is 12–16 hours and up to 36–48 hours for large stationary batteries. With higher charge currents and multi-stage charge methods, the charge time can be reduced to 8–10 hours; however, without full topping charge. Lead acid is sluggish and cannot be charged as quickly as other battery systems. (See BU-202: New Lead Acid Systems)
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.
