How the Charging Modes Work

The AL1802 MO intelligently selects the best charging method:

Parallel Charging (Dual Slot Mode – 21 A each)
If two batteries are inserted within 5 seconds, both charge simultaneously at 21 A each.

Sequential / Priority Charging (Single Slot Mode – up to 42 A)
If batteries are inserted more than 5 seconds apart, one battery is prioritised and charged at up to 42 A for the fastest possible turnaround. Both batteries are actively cooled during charging.

This system allows professionals to either maximise total throughput (two batteries at once) or maximise individual battery speed when urgent turnaround is required.
