Detailed overview: Makita 18V 5Ah compatible battery
This replacement battery BL1850B is designed for Makita 18V LXT cordless tools (BL1850, BL1860, BL1830, BL1840). Over time, the original battery loses capacity and runtime drops: replacing it gives your device a full day of use again.
With a capacity of 5.0 Ah, it matches the original battery's characteristics. Before ordering, be sure to check the exact reference of your battery (BL1850B) and the precise model of your device, as variants exist across series.
Tip: a spare battery charged in advance is also a handy safety net for outings, travel or long sessions, so you never run out at the wrong moment.

Frequently asked questions: Makita 18V 5Ah compatible battery
Yes, with 18V LXT tools, whose mount is shared across the entire range, from the rotary hammer to the site radio. Do not confuse it with the more compact 12V CXT range, which uses a different mounting. If your tool says 18V LXT on its label, this pack suits it.
In the vast majority of cases this is not a failure: the pack is outside its temperature range, too hot after sustained use or too cold in winter, and the charger waits rather than forcing it. Let it return to room temperature and charging starts on its own. If the flashing persists on a temperate pack with clean contacts, that points to a failing cell.
