Important • A fault condition is caused by a problem with the battery. The charger may indicate a fault because the battery is too hot or cold to charge reliably. Try to charge the battery again when it returns to the room’s ambient temperature. If the Amber indicator starts flashing on the second attempt, the battery should be discarded. Always dispose of batteries in a proper manner. Refer to Appendix D

Note • Charge times are for completely discharged batteries.

Partially discharged Battery Packs will take less time than listed in the chart to reach a fully charged state. Once Battery Packs have reached 80% of their charge capacity they may be used, but it is recommended that you allow the batteries to reach a full charge to maintain maximum battery life.

The UCLI72-4 Quad Charger’s safety features will stop charging a battery after six hours regardless of its charge state.
