This battery feels like the real thing. It holds its charge like a beast. So worth the extra money. Don't waste your money on a knock-off. The difference is immediately evident. Lives up to the high standards of Makita.

Built to last
Excellent battery. I bought it in 2020 and it’s now 2025. Still going strong and charges fast.

Awesome for Makita Jackets.
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

Great light weight batteries for sub-compact Makita tools
Got these as spares for the brushless sub-compact impact driver/drill driver set. These are half the size and weight of most other Makita 18V LXT batteries (3, 4, 5 & 6 Ah) but perfect for sub-compact tools which I bought for everyday small jobs because of their light weight and handier smaller size. These batteries recharge in 25 min and last for many, many DIY projects. I only recently went cordless and carefully compared Makita, Milwaukee & DeWalt. I chose Makita for their leading edge LI battery technology, generally good to excellent reviews by experts and their growing selection of brushless tools. Brushless tools can maintain constant speed under varying loads and have not brushes to wear & replace. If you are looking for larger capacity, longer lived Makita batteries, consider the newer 5.0 Ah BL Makita BL1830B-2 18V LXT Lithium-Ion 3.0Ah Battery 1850B, they are currently less expensive than the 4.0 Ah and 6.0 Ah models.

Perfect for trim routers
The battery arrived quicker than expected and clean as could be in a well packaged box tho not in original Makita packaging (which always makes ya feel better). It was dead as a doorknob, but 15mins on the charger and it was at full power. These smaller profile batteries are absolutely mint for trim routers that get way too top heavy with a 5ah on em.
