While I have corded backups for the most critical power tools, keeping my stock of batteries in good shape was one of this week’s small chores. The manuals state that if the batteries stay on the charger for eight hours the cells will be rebalanced. I haven’t taken any of them apart to do my own testing, most of the batteries I have are a decade old and all still hold a great charge. Recently I’ve bought a few more.

The other thing I’ve done is build a small adapter that connects a battery to Anderson Powerpoles. From the Powerpoles I can use the batteries to run any of my ham radio gear, charge USB devices, or connect to darn near anything else that can use it.
