## Description

The Makita 18V Compact Lithium-Ion battery charges faster and works longer than standard 18V compact lithium-ion batteries, giving you and your Makita cordless tools unmatched performance and productivity in a compact size. The Makita 2.0 Ah battery delivers up to 50% more run time per charge than the Makita BL1815 18V Compact battery, with a fast charge time of only 25 minutes for increased efficiency. Makita 18V Lithium-Ion batteries resist self-discharge so they're ready for use even after long periods of storage. The Makita Rapid Optimum Charger (sold separately) is a smart-charging system that communicates with the battery during the charging process to monitor current, voltage and temperature. This advanced charging technology helps optimize battery life and deliver a faster charge. In addition, the Charger has a built-in fan to cool the battery for faster and more efficient charging, even in hot weather conditions. For improved tool performance and extended battery life, Makita created STAR Protection Computer Controls. STAR Protection is communication technology that allows the tool and battery to exchange data in real time and monitor conditions during use to protect against overloading, over-discharging and overheating. Makita, the innovation leader in cordless tool technology, has the world's largest cordless tool line-up powered by 18V lithium-ion slide-style batteries.

Review: Built to last - Excellent battery. I bought it in 2020 and it’s now 2025. Still going strong and charges fast.
Review: If you carry your impact in a holster or do overhead work, this is worth it - I bought this primary for my impact. I got a tool belt but the 5AH batteries add so much weight it felt like a lead weight hanging off my hip. This battery fixes that problem at the cost of battery life of course. If you're holding a tool overhead a lot this battery also helps with fatigue. Hopefully it lasts, I have had 3 Makita batteries fail, two 5AH and one old 3AH. The 3AH I tried to charge when it was cold and Makita in it's infinite wisdom turns the battery into an expensive brick after it records 3 failed charge attempts. The other two failed to charge randomly, with one of those having the flashing battery charge level LEDs of doom. Makita replaced the 5AH ones under warranty. The first one turned around in a few days from the repair center, the second one took over a month. I think Makita has consolidated it's repair centers on the West coast and now it's taking much, much longer for service as the remaining repair centers are overloaded. If you're a pro who needs fast repair service beware.

### ⭐⭐⭐⭐⭐ Awesome for Makita Jackets.
*by W***Y on October 30, 2025*

I bought this to use with my Makita 18v heated jacket. It's a great size that doesn't weigh down the pocket or stick out too much. That high quality you can expect from Makita. Lasts about 4-5 hours in my jacket on high. Don't know about tools cause I use all 40v. Charges in about 10 minutes in my experience, which is always great
