The Chargers of Choice for Major Manufacturers

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

Inverter Chargers

Smart Battery Lithium Batteries work with any Inverter / Charger designed for Lead Acid, Gel or AGM Batteries. Smart Battery recommends programming the remote for your inverter / charger to the following specifications:

Bulk: 14.4V

Absorb: 14.6V

Float: 13.6V

If your Inverter / Charger does not have a setting for the voltage, you can choose the best setting by selecting either a Lead Acid, Gel or AGM profile that gets the voltage during bulk or absorb closest to 14.6V. If you are not able to change anything about your battery type and your charger is not programmable, you will want to check what voltage it charges up to to be sure it will get around 14.4V - 14.6V to sufficiently charge the Smart Battery. If your charger only charges to 13.9V, this will not fully charge the battery. The lower level does not hurt the battery, but it is like only filling your gas tank 80% full.


Solar Controllers

Smart Battery Lithium Batteries work with all standard solar controllers. We recommend programming your controller to the following specifications:

Bulk: 14.4V

Absorb: 14.6V

Float: 13.6V
