WET CELL BATTERY CHARGING ALGORITHM

Auto Equalize: 

The GP-PWM-10-SQ has an automatic 

equalize feature that will charge and recondition your bat-
teries once a month at a higher voltage to ensure that any 
excess sulfation is removed. This feature is recommended 
for Flooded batteries only. Check with your battery manu-

facturer.  This feature is only available for wet cell or flooded 

batteries

Soft Charge- 

When batteries suffer an over-discharge, the controller will softly ramp the battery voltage up to 10V.

Bulk Charge-

Maximum current charging until batteries rise to Absorption level

Absorption Charge-

Constant voltage charging and battery is over 85%

Equalization Charge*- 

Only for WET battery (Flooded lead acid) or Calcium battery type, when the battery is deeply drained below 

10V, it will automatically run this stage to bring the internal cells as an equal states and fully complement the loss of capacity. (Gel and 
AGM battery do not run Equalization charge)

Float Charge-Battery is fully charged and maintained at a safe level. 

A fully charged battery has a voltage of more than 13.6 Volts.
