Makita 18V Batteries
These Makita 18V batteries cover the LXT platform — Makita's 18V lithium-ion system spanning 275+ tools with one battery standard. Replacement packs match the original part numbers, including BL1850, BL1840, and BL1830 equivalents, with grade-A cells, full protection circuitry, and drop-in slide fit. "B"-suffix models (BL1850B) add the on-board fuel gauge — our equivalents match the original's communication too.

Frequently Asked Questions
What's the difference between BL1850 and BL1850B?
The "B" suffix adds an on-board charge-level indicator. Capacity and fit are the same — both work in every Makita 18V LXT tool.
Do all Makita 18V batteries fit all LXT tools?
Yes — every LXT slide-pack fits every 18V LXT tool. Match capacity (Ah) to your runtime needs, not the tool model.
How long does a Makita 18V battery last?
Typically 2–3 years or 300–500 charge cycles. Store packs half-charged in cool, dry conditions and avoid deep discharges to maximize life.
