Last night after work, I was using an M18 angle grinder with a wire brush to prepare some columns for the shop mezzanine I'm building for primer. It was about 100°F outside. I was using 6Ahr and 8Ahr High Output batteries. The columns are 3-1/2" square tubing about 9' long. I couldn't even complete two sides of a column before the batteries (it happened with three different batteries) went into over-temp mode and quit working. That was probably 5 minutes, maybe 10 minutes of running. If you've run grinders in high ambient temps, what has your experience been? Do you have to rotate batteries and cool them down?
Thanks,
