Lithium Battery Chargers and Accessories

We offer several battery chargers and accessories recommended for use with our batteries. These chargers come with a specific algorithm that is designed to charge CHARGEX® Lithium Batteries. 

Multi Stage Battery Chargers

There are many different types of chargers and even more algorithms that charger manufacturers update with advancements in battery technology. Charger manufacturers create algorithms that determine what current and voltage output the charger delivers to a battery. Lead acid, gel, and AGM batteries are inefficient and build up heat during charging which can cause the battery to swell, leak acid, and damage the plates. The algorithms are designed to minimize these effects.

There are typically 3 stages to charging a lead acid, gel, or AGM battery - bulk, absorb, and float:

1. The Bulk Stage: at this stage, the charger will typically deliver a steady amount of current at its highest rate to get the battery filled quickly. Many times during charging, the charger may slow down the bulk amperage to prevent damage due to heat build up. Lithium ion batteries do not heat up during charging or discharging so they can absorb all of the energy more quickly from your charger.

2. The Absorb Stage: at the absorb stage, the charger will begin to slow down the amperage as the battery charger is reaching the voltage to which it is set to charge the battery.

3. The Float Stage: this stage is where the voltage to which a battery would normally float down and sit at while fully charged - the charger holds the voltage at this stage by delivering a small amount of current.
