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 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.

Rated 1 out of 5 by from M-18 Lithium- Ion battery Surprisingly weak performance for such a brand name, short usage time and after two years- completely dead!

Rated 4 out of 5 by from 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.
