Makita BL1820B-2 18V Compact Lithium-Ion 2.0Ah Battery Twin Pack

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

Good product

i bought these over the generic brands because i wanted a product with no issues. batteries work great and really last - the 2 amp hr are light weight so great for the hand held tools. didn't last so long when used on the dyson vacuum - a little dissapointing

I rate it to excellent as expected

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.

Nice and light, fine for smallish tasks. Still, nothing to sneeze at compared to Ryobi 18+. (I have a Ryobi in the house, Makita in the shop) If you are just working on a weekend project, these provide enough juice for a few hours of use. Use the 3 Ah or 4 (or 5)Ah for the longer jobs, and these when you want to lighten your arm.These are noticeably less juice than the 3Ah, but that's the tradeoff for being light and small. The other uptick is, charging time is super fast.

Right battery, great price, fast delivery!

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 BLMakita BL1830B-2 18V LXT Lithium-Ion 3.0Ah Battery1850B, they are currently less expensive than the 4.0 Ah and 6.0 Ah models.
