Most chargers on the market today aren’t true three step chargers. Here is a quick overview of what can happen to your expensive batteries by not using a multi-step smart charger on a regular basis:

A) Taper chargers – Simple Ferro resonant chargers deliver current at a reducing rate as the battery voltage rises during charging, until the current tapers to zero at a certain voltage. Unfortunately, there is no single voltage setting that allows the charger to remain connected to ensure a full charge is reached. If the voltage is set above the safe float voltage, the battery will be overcharged and may suffer damage from boiled-off electrolyte over time. If the voltage is set at or below the float voltage, then the battery may never be charge properly. These chargers are NOT “Set and Forget” chargers.

B) Two Step chargers – These chargers typically charge at a constant current until the battery reaches a preset voltage, and then the charger voltage is reduced to a safe float voltage. There are two problems with this, if the preset voltage is at or below the battery absorption voltage, the loss of the absorption stage of charging will result in an undercharged battery. If the preset voltage is above the absorption voltage, then the battery will be overcharged. Repeated overcharging will cause loss of electrolyte and eventual battery damage.
