For improved tool performance and extended battery life, Makita created STAR Protection Computer Controls.

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

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

Passgenau und hohe Ausdauer. Wie geschaffen für kleinere Geräte wie meine Gartenschere.

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.
