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.

California residents: seeProposition 65 information

  • Battery resists self-discharge and remains ready for use even after long periods of storage

Rated 3.4 out of 5 by 26 reviewers.
Rated 4.0 out of 5.0 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 5.0 out of 5.0 by Makita 18volt Compact Battery Batteries are for several tools, plus back up spares. We will order again, when necessary. February 17, 2015
Rated 5.0 out of 5.0 by Good battery. The battery was cheaper online that at the store. Overall the set of drills is not excellent but the battery does what I expected. February 14, 2015
Rated 1.0 out of 5.0 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 1.0 out of 5.0 by Battery life - One year :( After one year of daily charging, one time per day, the battery no longer accepts charge. So I can no longer use the product. I'm going to try a different brand if it will work in my Makita radio. I only use the battery for the radio, & get roughly 4.5 hours of constant play power. Perhaps it's just this compact style, but other reviews are inconclusive. February 2, 2015
