Common questions
Do not assume compatibility from matching voltage. HART and WORX specify their own battery systems; check the exact tool manual and approved battery list.
HART lists kit and bare-tool versions. Its 40V brushless 15-inch kit listing specifies a 4.0Ah battery and charger, while bare-tool listings exclude those items.
Runtime varies with battery capacity, vegetation, cutting technique and tool settings. Consult the maker's manual for the exact model and treat runtime estimates as conditions-dependent.
No cross-brand fit should be inferred from voltage. Verify the manufacturer's compatibility information for the exact trimmer and battery before use.
