CEENR 5.0Ah Battery for Makita 18V LXT BL1850B BL1850 Replacement

The CEENR 5.0Ah battery is a drop-in replacement for Makita 18V LXT slide-pack batteries — it replaces Makita BL1815, BL1820B, BL1830B, BL1840B, BL1850B, BL1860B. It fits the same battery slot, needs no adapter or modification, and charges on the Makita charger you already own.

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 Makita 18V LXT tools with a star or yellow battery plate, 18V X2 (36V) tools included — 347 verified models, including the XPH12Z hammer drill, XFD12Z drill/driver, XDT16Z impact driver, XWT08Z impact wrench, XSH03Z circular saw, XRJ05Z reciprocating saw, XAG04Z grinder, XRH12Z rotary hammer, XNB02Z nailer and XBU03Z blower. Makita's manuals list only packs up to 4Ah for the XRV01Z, XRV02Z and XRM02W. Full list: ceenr.com/compatibility/makita-18v-lxt. Not for early LXT tools without a star or yellow plate, or 14.4V, CXT and XGT-only tools.
