CEENR® is an independent brand — not made by or affiliated with Craftsman. Brand names indicate tool compatibility only. The CEENR 5Ah battery is a drop-in replacement for Craftsman 20V Max tools — it replaces the CMCB201 series and the full Craftsman 20V Max slide-pack family, built with premium high-drain cells and 4-layer BMS protection. At 5Ah 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.
