CHAUNVEN 6.0Ah Battery Replacement for Makita 18V Battery Compatible with 18 Volt BL1860B BL1850B BL1840B BL1830B BL1815B Batteries

These batteries are working great so far. They seem to have the indicated battery life, or at least close to it. Definitely better than my old 1.5ah batteries. My tools were feeling sluggish and weak, constantly charging batteries up. These make my tools feel like new. Perfect fit. Doesn’t fall off. No charging issues. Much more cost effective too.

Charge lasts awhile. Works as expected

My power drill and my power impact work so good with this batteries

I compared these to Makita's 4.0Ah batteries. I have a Makita edger, string trimmer and blower that each require two batteries. When I cut my lawn I edge, trim and then blow everything down when I'm done. I have a lot of sidewalk and curbing to blow down. The Makita batteries have a slight edge and are drained just before finishing the blowing. These batteries drain a little sooner. But the replacement coast of Makita batteries are not worth it.

Definitely work as lower cost alternative to Makita batteries. Work great on our hammer drill and hold their power well enough. We are using them to drill in granite so it’s hard to say if they last as long, almost or less than compared to same size Makita battery but they seem to work quite well so far and also charge on our Makita charger.

Don’t really last long and don’t seem to put out anymore power than a 4.0 the charge never shows full

Excelente todo bien asi como lo pedi

These might fit Makita tools, but they don’t perform like real batteries. Power drops off quickly and they don’t seem to hold a charge nearly as long as advertised. Build quality feels cheap too. The casing and connections don’t inspire much confidence, and I wouldn’t trust these for anything important. You’re better off paying more for the real thing than dealing with inconsistent performance.
