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

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.

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.

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

works good as original but costs much less.

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.

Works great with my tools I don't see any difference between the original and this one give me the power when using and charging fast and reliable and the price is right recommend to have for backup
