The Makita 18-Volt Compact Lithium-Ion battery charges 4x faster than comparable Ni-Cd batteries. The combination of Makita's rapid optimum charger (sold separately) communicates with the battery's built-in chip to optimize battery life by actively controlling current, voltage and temperature; and has a built-in fan to cool the battery to produce more lifetime work. The battery takes only 15 minutes to recharge.

Rated 3.1 out of 5 by 18 reviewers.
Rated 4 out of 5 by It is what it is... it's a battery. We had purchased the drill and needed a second battery to swap out with. The unit gets used off and on about 80 hours per week. The batteries charge quick and are adequate enough to keep us going with several changes throughout the day. We have had the drill and batteries a couple of months now and all seems to be well. There does not seem to be any decline in performance. The beauty of these are that they are so light weight in comparison to the De-Walt 18V drill/battery we were using. I do not feel they have the torque and power of the De-Walt and the batteries do not seem to hold a charge for as long as the De-Walts, but for the difference in weight (with a lot of the use being above shoulders), it is well worth the effort to swap batteries more often.

Rated 1 out of 5 by Worst Battery Ever I bought a combo set for over 500.00 and after a year none of the battery's will charge after a year . am going to send another 300.00 on 3 battery's . WILL JUST BUY A NEW SET OF ANOTHER BRAND> MAKITA LONG YET ANOTHER CUSTOMER !!!!! November 2, 2014
Rated 1 out of 5 by Unhappy with this product Similar to many of the other costumers who have written reviews I, too, am having trouble with the battery. I have only had the drill a little over a year and the battery pack is flashing red and green. From what I have read that indicates that it is no longer accepting a charge! This makes me very unhappy considering the new battery will cost over 80 dollars! I am not going to put more money into a battery and product that is likely to fail in another year!I read that Makita will not do anything if it is over the year warranty. Shame on them for not standing by thier products. I will not buy another Makita drill! I had a Dewalt for almost 10 years. That battery and drill was strong during that whole time. Looks like I will go back to Dewalt. August 6, 2014
Rated 1 out of 5 by Poor Battery This is the first time I felt the need to write a review about a product. After only six months one of the two batteries stop charging for my drill. The batteries are too expensive for this type of quality. Looking at the other reviews I think this is a hit or miss product. Very disappointed! December 8, 2014
Rated 1 out of 5 by Mikita drill I have now bought 4 of these batteries . I love the overall drill itself but the batteries just don't last My next drill will be a ryobi October 14, 2014
