excellent product, but!
this battery setup is the real deal. this products only shortcoming is that the battery "dies" about 6 months in. this is based on full time 40 hour work weeks. but it still is the best i have used to date.

2 years and counting
We have four batteries that run two drills, two impact drivers, two flashlights, and a radio. The batteries have been stored for days in a pick-up with 100*F plus tempatures and left outside in 20*F nights. They even had 2 weeks of swimming pool duty with 80%+ humity. Just like the watch takes a lik'n keeps on tick'n.
The batteries are quick to charge +/- 15 minutes and give us any where from three to four hours of work time. One thing we have found, is to remove the batteries from the charges as soon as possible after the battery is fully charged.
I have recommended the Makita 18V family to friend and family and all have given me great feedback.

Mega power but short life span
The 18V Makita Impact is worth its weight in gold but the batteries have a short life span. It is used for home projects only and both original batteries have died (will not take a charge)in less than two years. I have other guns that are 10+ years old and batteries still take a good charge.

Easy To Use
They seem to die too quickly...
The Makita 1/4" hex impact driver is incredible tool...I use it for everything as with a fresh battery it will drive (using adapter) 1/2" sockets in tight spaces and save my old hands. The batteries are compact a charge fast until they die...~1 year and will not charge due to a bad cell I assume (probably senses individual cells).

Drill great, batteries bad
This drill is great, but I can't afford to keep it in batteries. Bought the drill with 2 batteries. Very occasional use. Replaced an old Black & Decker 12V, its batteries still work, a little. About a year after purchase, one of the batteries wouldn't take a charge. The electronic charger just flashed the "bad battery" signal. I replaced the battery. A few months later, another one conked out. Same problem. Interesingly, I know the battery is NOT bad, as I could charge one battery, and jumper the charged one to the "bad" one and the two would equalize. Repeating process gave me a semi-usable battery.
Now the third one has conked out. Same problem.
At $80 a pop, it's cheaper to buy a new drill..which make no sense.
