why woluld that happen if the voltage is the same and the amp hour ive had a couple of old makita drills and the switches went on them just poor quality switchesMy mate got similar to run his old DeWalt 18V gear on new 18V Li-ion batteries. Burnt the "triggers" out in two drills.

Modern batteries will allow/supply more current than old Nicads, and for longer. So if work the drill harder, for longer . . . and the smoke gets out . . . did it with electronic speed control for my R/c buggies. Futaba came out with a near enough bomb-proof electronic speedos for brushed motors and nicads. When I returned to the game a few years ago, the same motor on the same speed control as 30 years ago blew on the power lithium polymer batteries can deliver.Only thing I could think of was if the switches had a duty cycle and bugger Ah batteries allowed longer tool useage.
