CEENR 5.0Ah Battery for Worx 20V PowerShare WA3520 WA3525

The CEENR 5.0Ah battery is a drop-in replacement for North American Worx 20V PowerShare slide-pack batteries — it replaces Worx WA3520, WA3525, WA3575, WA3578. It fits the same battery slot, needs no adapter or modification, and charges on Worx 20V PowerShare chargers such as the WA3742 and WA3881.

At 5.0Ah it delivers far longer runtime than the smaller packs most tools ship with — ideal for contractors, remodelers and serious DIYers who run drills, impact drivers, saws and grinders through a full workday.

Inside are premium high-drain 18650 lithium-ion cells that hold voltage under load, managed by a 4-layer BMS with over-charge, over-discharge, over-current and short-circuit protection. Certified to the IEC 62133 lithium battery safety standard.

Tool fit: runs North American Worx 20V PowerShare tools, 40V and 80V tools (two or four packs) included — 165 verified models, including the WX102L and WX176L drill/drivers, WX352L hammer drill, WX261L impact driver, WX272L impact wrench, WX520L circular saw, WX550L reciprocating/jig saw and WX516L reciprocating saw. Not listed for this pack: the WX097L (listed for packs up to 2Ah). For covered-bay tools such as mowers, make sure the cover closes over the pack.
