Due the persistent heat, powered the crunchers down [but the laptop that has it's battery now inserted, then forgot that UPSes when not under load, continue to trickle charge. Days later, they still felt warm even when the power switch on the UPS had them disabled for service, but what that appeared to have done was just switch off the power to the attached devices, stop the alerting if the grid power drops, but not the charging, so unplugged them from the wall. A quick kill-o-watt meter test, these battery packs even at 100% charged were still eating 20W/Hr, and with 2, silly 960 watts a day. Now they're off-off till the heatwave subsides.

Now a day later, they're just ambient temp... no low energy [inexplicable] chemical or nucular [warm] fusion processes keeping them going :P

edit: Don't and dont's ;>)
