Rated 3 out of 5 by from 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 4 out of 5 by from 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

Rated 4 out of 5 by from Does the job at a great price Best feature is how quickly they take a full charge. Small battery makes handling easy without fatigue.

Rated 5 out of 5 by from 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.
