MULTISTAGE CHARGING PROCESS:
Stage 1 - Bulk
charging voltage, known as its absorption voltage. In this step, around 80% of the
battery is charged as fast as possible.
Stage 2 - Absorption, for the remaining 20% of the battery, the iTECHBC25 output
will taper off as the battery approaches full charge.
Stage 3 - Float, the iTECHBC25 voltage is lowered and held at a constant and safe
predetermined level. This prevents the battery from being overcharged, yet allows
the charger to supply enough current to make up for the self-discharge losses of the
battery, while supporting any additional loads connected to the battery.
Sta
ge 4 - Maintenance
outputting power. Once your battery drops below a predetermined level (depending
on your battery type), the iTECHBC25 will kick back in, maintaining your battery's
state of charge.
