The CEENR 8Ah battery is a drop-in replacement for Worx 20V Max tools — it replaces the WA3520 series and the full Worx 20V Max slide-pack family, built with premium high-drain cells and 4-layer BMS protection. At 8Ah it delivers far longer runtime than the smaller packs most tools ship with — ideal for contractors, remodelers and serious DIYers who run drills, saws, grinders and impact drivers through a full workday. It charges on your existing Worx charger, carries a 3-year warranty, and ships from a US warehouse — fewer battery swaps, no mid-cut downtime, and a fraction of the cost of a genuine OEM pack.
Aftermarket — done properly.
More runtime, premium high-drain cells, real multi-layer protection — backed by a 3-year warranty and US support. Not a cheap clone.
Far longer per charge than the small packs most tools ship with — fewer swaps on long cuts and drilling runs.
High-drain cells that hold voltage under load — the same format premium OEM packs use, never B-grade.
Over-charge, over-discharge, over-current and short-circuit protection, tested to global lithium-safety standards.
7-day no-questions returns, shipped and supported from our US warehouse.
