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.
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.
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)
Lead acid is sluggish and cannot be charged as quickly as other battery systems. Lead acid batteries should be charged in three stages, which are constant- current charge, topping charge and float charge.
Yes, you can charge a lead acid battery indoors, but it’s important to ensure proper ventilation. Lead acid batteries can release hydrogen gas during the charging process, which is highly flammable. Therefore, it is recommended to charge the battery in a well-ventilated area to avoid the risk of explosion.
Power Sonic recommends you select a charger designed for the chemistry of your battery. This means we recommend using a sealed lead acid battery charger, like the the A-C series of SLA chargers from Power Sonic, when charging a sealed lead acid battery. Sealed lead acid batteries may be charged by using any of the following charging techniques:
