So, I have some BAT612 18V batteries from Bosch.

I should be able to use both batteries with either of my tools (Angle Grinder - GWS18V-45PC, Drill - DDS181A), but one battery works in both tools and the other only works in the drill.

Does anyone know why this is the case?

Or maybe how to fix it?

    Maybe one is tired and the circuitry in the grinder doesn't consider it adequate. The tools are designed to not over-drain LI batteries because that can destroy them.

  • @isherwood OCP/UVP is handled by the battery's charge controller (built into each battery pack), not the tool.

  • You're probably right, but I wonder if it isn't a little of both. My only other idea is a quirky contact issue.

  • Yeah, I could see that the contact issue, but they both are fairly straight and new, but I did notice when I clicked the battery in that doesn't work in the Angle Grinder. I can push the battery check button and everything is OK until i press the tools trigger. Then it cuts off.

Contact issue, I think. Please see if one tool has a deeper contact than the other. Or rough up the tool contact with some sand paper.
