Review: Affordability - The batteries work just as well as the more expensive milwaukee brand
Review: It fits Milwaukee laser, in case you wondered - It was impossible to find out what model # battery would fit our ancient 3522-20 Laser (circa 2022) which had a missing battery. I couldn't find reference to this laser on the internet or ref to this battery being used with a laser. So I took a chance and ordered this 48-11-2131. I am pleased to report that it is the proper battery!! YaY . Seems to be working now. Will try to update with battery longevity info after some time.
