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

These are awesome! They keep strong, I would definitely buy it again.

Just get them already! They work! I have a Makita set that was a father's day gift from my wife that we have been using for over 12 years now. The two batteries that came in the kit just were not getting the job done any longer. They needed multiple charges just to get through a small job. We ordered these bigger batteries and praise be to HE the drill came back to life! The drill acts like it is brand new again and the blower that we have lasts for more than 45 seconds per charge. I can actually use my devices again.

I honestly wasn’t expecting much from a non-name-brand battery, but this thing proved me wrong fast. Snapped right into my drill like it was made for it and held a charge longer than I expected. I’ve been swapping between two for heavy-duty projects and neither one has flinched. No overheating, no weird charging issues, just solid performance every time. It feels just as tough as the original Makita one, maybe even tougher, and it doesn’t cost an arm and a leg. If you’re tired of babying your tools or getting gouged on name brands, this is the one to get. I’ll be grabbing another set before these vanish.

Good batteries. Fits my Makita charger & all of my Makita tools

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.

So far, these batteries have been good. No complaints so far. Been a couple of months so far of moderate use.

Batteries purchased March 31, 2025. It’s now November 30, 2025. In 7 months of ownership, the batteries are no longer holding a full charge. Bought them for my string trimmer, blower & reciprocating saw. I could barely trim the yard with 1 battery, 1/4 acre. The blower would work for 15 minutes with 1 of these batteries. Very poor quality. Not convinced they are lithium ion batteries. Wouldn’t buy them again.

Well kind of 50-50. I can't get one of the batteries to charge past 25% (according to lights), and it discharges quickly. The other seems fine, although not the capacity of an OEM battery. If they both work they are a deal. Since I only have one, not such a good deal. Update: Well I am pleasantly surprised. The vendor quickly replaced the faulty battery. They initiated the replacement without me having to beg for it like so many other vendors. They clearly want to make the customer happy. They have my respect.
