The Makita 18-Volt LXT Lithium-Ion battery charges faster and works longer than standard Lithium-Ion batteries, giving you and your cordless tools unmatched performance and productivity to take on the most demanding applications. The Makita 4.0Ah battery, model BL1840B, combines more run time (35% more run time per charge than the Makita BL1830 battery) with a category-leading charge time of only 40 minutes so it spends more time working and less time sitting on the charger. For added convenience, it also features an on-board LED charge level indicator to monitor battery charge. The 18-Volt LXT 4.0Ah battery is compatible only with Star Protection tools, indicated by the Star Symbol and/or Yellow Battery Receiver under the tool. Makita 18-Volt 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.

Very good rechargeable batteries. The fuel gauge is very good to make sure how much power is left!
Coby Gibson (verified owner) –
These battery packs are as good as it gets, very easy to use, and charging rate time is excellent. Now, as far as how long they last when used, you will be amazed. I’ve used all kinds of battery packs, and they are all different depending on the tool they are driving, but these rank up there with the best of them. When they say “high capacity”, they definitely meet that definition. So, yes I would definitely recommend these if compatible with your tools.

If you own a makita this is a must
Jonas Emmerich (verified owner) –
They seem to be lasting longer then the 3.0 I have. Not happy with the charging time, it states it’s a quick charger, but takes an hour to recharge the batteries.
Keenan Shields (verified owner) –
These batteries are the best: I’m a self employed carpenter and I haven’t seen better running life than the Makita batteries.
Davin Schowalter (verified owner) –

Eleonore Herzog (verified owner) –
Got this for free with purchase of the compact drill kit. Excellent product.
Emelie Parisian (verified owner) –
This pair of 3.0Ah batteries is supplementing my original 1.5Ah batteries. These batteries keep my older Makitas running and work with the newer brushless tools which I am considering buying.
Arlo Bergnaum (verified owner) –
Expensive batteries, but do the job
Aiden Hirthe (verified owner) –
Great deal. These two batteries were exactly what I needed to not have to stop and recharge the one battery I had. I could not pass up the deal when I saw it. Ty
