Thread: Battery chainsaws

Seems to work OK on light drains like a torch or a drill using a small drill, but on grinders or circ or recipro saws it shuts off virtually straight away.

Thanks, good info! So is it possible to test the batteries to diagnose, or do I need to try the saw with different batteries?
