Customer Reviews

Endless power!
Really, these batteries provide seemingly endless power. They hold their charge for weeks with very little loss. I can use one battery for drilling and driving throughout an entire (moderately sized) project. They are extremely lightweight and charge in twenty minutes or less usually (in hot weather it takes longer). All three of mine slide on and off easily, with no issues of binding or falling off. With all the praise comes a VERY important caveat. DO NOT run these batteries into the ground. The instructions state that as soon as you notice a loss of power, stop and charge. If you over-discharge Li-Ion batteries, you can seriously degrade the life of the battery. These batteries are 1/3 cheaper on Amazon.com than at the home centers, so buy from here! Also, only the cells themselves are made in Japan, all other parts are made and final assembly is in China.

The Big Makita Lithium Ion Battery
It's a battery. It has held its charge. It has plenty of stored energy. It hasn't died yet (like two of it's smaller bothers have).
It is evidently pretty high tech. I brought the first smaller version that quit on me to a Makita repair center. The tech plugged it into his diagnostic do-hicky and said, "Gee, you've only had twelve cycles on this".

Makita 18V lithium battery
I like the small size, low weight, and high power capicity of these batteries and the associated Makita tools. My only complaint is that some of the batteries are tight and very hard to remove from the tools. This problem tends to become worse with use. Also be careful with the charger - is works well but is VERY dellicate and will break / cease to function if dropped or banged around.
