Definitions of P12 loading steps are defined below. The charging stage LEDs on the front of the charger indicate the current stage.
Mass (Continuous Current)

1. The bulk charging stage is the first stage of the battery charging process. This is where most of the charging actually takes place, leaving the batteries for approx
75-80% of their final capacity. The purpose of the bulk stage is to quickly drive current into the batteries to boost their voltage. When all batteries have reached the specified absorption voltage, the charger moves them into the absorption phase.

2. Absorption (constant voltage)
In the absorption charging stage, the batteries stop their charge, discharging them. This is a less aggressive charging stage than Bulk charging, where the current going to a certain battery bank decreases significantly over time. The conditions under which a battery bank is considered full depend on many different factors. In order for the battery bank to exit the absorption phase, several different parameters must be met. The main parameters are the absorption timers, which you can see on page 14. The outputs go from individual absorption to pre-swimming. When all the batteries have finished absorbing, the charger moves them to the floating position.

3. Float* (constant voltage)
Float is the last stage of charging for fully charged batteries. Batteries in this stage are kept at their specified floating voltage. Typically, the float voltage is 1.0 V or more different from the sink voltage.

4. Eel float (constant voltage)
The Pre-Float charging stage is unique to the P12. As the size of the battery banks usually varies by output, each battery bank must be charged separately.
When all the batteries are absorbed, the battery banks can stop charging at different rates. Once the battery bank has met its unique absorption parameters, the P12 charger moves it autonomously into the pre-charger.

Float stage. Pre-Float is the initial stage to maintain a fully charged battery. Pre-Float batteries can have a difference of up to 0.5V
between batteries in absorption. Pre-Float can have up to two outputs at the same time.
