Affordable Milwaukee
These were on sale at another famous name brand big box store for nearly twice the price. These great deals are how I have been able to afford Milwaukee Tools. Thanks Walmart plus for making my Christmas shopping such a good deal!
Verified Purchase
I found name brand Milwaukee batteries at this price! 2x 5 Amp hour Batteries for $109. Thank you Walmart. Because of course they are Milwaukee brand so they are the highest quality, they charge up quickly and they hold a charge! You cannot find them at this price ANYWHERE else.

Brand new in the box. I made the mistake of buying the last batteries on EBAY. When I got the Ebay batteries , they were at least 10 years old , but new. The one lasted a month, and the other one lasted a year. Hopefully the Walmart batteries last a lot longer, time will tell.
