What does voltmeter show on each battery? Typical charger will only charge what battery will accept. One bad battery or cable in the battery pack will cause charger to do this.

Ok, so two batteries showed bad? All batteries same age? Best to replace insets!

All same age, so all subject to problem.

Pack is only as good as weakest battery.
