I have found that some battery packs don??t always reach the required trigger voltage and the charger remains on in a trickle charge mode.*If this happens, unplug the charger from the wall outlet, your cart should be fully charged. Most of the times after the charger has completed a few charge cycles the charger will begin to operate automatically.*The charger operating in the manual mode will not harm your battery pack, you will just have to manually disconnect the charger after the required charge time of not more than 14 hours.
