Rated 4.3 out of 5 by 7 reviewers.
Rated 5.0 out of 5.0 by Quality Batteries This set of batteries have been working great with my drill, infact i believe they work better than the original, hold their charge longer and diffinitely charge much quicker. Over all Im very happy with the performance and quality of this product. I thought the price was also reasonable when comparing with other online suppliers. It also shipped quickly and correctly. July 3, 2013
Rated 3.0 out of 5.0 by plan on replacing your battery set every 2 years, but it is an excellent battery (lightweight, reliable) in an exceptional line of tools milwalkee makes top notch cordless power tools for the professional. i use these 18v compact li ion batteries only on my drill. they generally do a very good job, but at times i wish they would last longer, but that is offset by the very short recharge time and i use two (one charging while i use the other). my only disappointment is the duty time markedly reduces after about 2 years. for the price, these should last much longer in my humble opinion.

Rated 5.0 out of 5.0 by Light weight, charge status indicator and powerful! Great deal on the 2-pack at Home Depot! Now have 3 18v batteries. Quick re- charge time means no down time! January 14, 2014
Rated 4.0 out of 5.0 by The product fit and worked well with my drill. The quality of the product was up to the usual Milwaukee high standards. Buying the two pack eased the price somewhat. May 22, 2013
Rated 4.0 out of 5.0 by Does the job at a great price Best feature is how quickly they take a full charge. Small battery makes handling easy without fatigue. July 9, 2013
Rated 4.0 out of 5.0 by Much better than 1st generation battery Was skeptical about getting new batteries because I was disappointed with the duty cycle. I am well pleased with the way these new ones perform. HD had the best price on the two pack March 28, 2013
Rated 5.0 out of 5.0 by Milwaukee M18 battery The price was very good for these new factory-quality OEM replacements. They have charged and worked very well. June 25, 2013
