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

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.

These batteries fit my Makita tools perfectly and hold a strong charge. They last a long time, charge without any issues, and perform just like the original batteries. Excellent value for the price.

Great value for the price! These batteries fit my Makita tools perfectly, charge without any issues, and provide solid runtime. So far, they’ve been reliable and perform just as expected. Highly recommended!

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.

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.

Scam, this thing cooked my charger first use and they barely last the battery time of legit ones just spend the extra 60 and go legit I had to return mine and just buy real ones. They do work performance wise but they die so much quicker

I've been using these constantly for a month and a half, they seem really good. I was disappointed when they arrived they are not the same size of my other 3000 mAh batteries. I think they are 1500 mAh but they are definitely worth the price.

Charge lasts awhile. Works as expected

Muy buena compra cumple con todo.
