3000mAh 18V Battery Replacement for Makita 18V Battery Compatible with 18 Volt BL1830B BL1840B BL1850B BL1860B BL1815B Battery (2 Packs)

The CHAUNVEN 3000mAh 18V Replacement Batteries surprised me with how well they perform, especially considering the price. They work seamlessly with my Makita tools and have held up well through regular use. What I Loved • Compatible with Makita tools: They click in securely and work just like the original BL1830/BL1840/BL1850 series batteries. • Good power and runtime: The 3000mAh capacity is solid for most everyday jobs. I’ve used them on drills, impact drivers, and saws without issues. • Affordable 2-pack: Getting two batteries at this price is a huge win. Perfect for keeping one charging while using the other. • Lightweight design: Slightly lighter than some OEM Makita batteries, which makes tools feel a bit easier to handle. • Fast charging: Charges reliably on standard Makita chargers without overheating. Could Be Better • Runtime is good, but not as long as higher-capacity Makita originals (like 5.0Ah or 6.0Ah). • The battery indicator lights are not as accurate as the OEM ones — still helpful, just not perfect. Verdict If you need reliable backup batteries for your Makita 18V tools without paying OEM prices, this 2-pack from CHAUNVEN is an excellent value. They perform well, fit perfectly, and are ideal for DIY projects, home work, or as spare batteries for jobsite use.

I am a professional collision repair technician, and I run these batteries hard all day. Sometime much harder than they should be run in my big drill. They the abuse, work perfectly, last all day usually, and charge quick. The last pair I bought lasted me 3+ years and I've got a couple months on the new set and they're doing great. This is an incredible value. PRO TIP: They aren't always fully charged, even when the charger and the meters say they are. Leave them on the charger to trickle and they usually have more left in them.

Work very well

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.

Holds charge. Very light

The batters seam to work and hold up well.

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.

I’ve had the since Fall 2023. In that time, I’d estimate about 30 charge cycles each. 1 battery is still holding up, the other no longer takes a charge. When working, these 6.0A batteries last about as long as a real Makita 4.0A battery. So you have to balance price against how long they hold a charge and how many charge cycles until failure.

fits my makita jacket perfectly
