Introduction
The battery of the Milwaukee Circular Saw 263020 B57A 2008 tends to deteriorate over a long period of time which leads to a strained battery.

You can also use this troubleshooting page before continuing with replacement. If the battery in your saw is strained, damaged or not charging, use this guide to remove and replace your battery.
