Why did my LED flashlights stop working?

One is an Inova 5 LED, aluminum body flashlight about 4.75″ long, uses 2 Lithium 123 batteries. The other one is a freebie from a Con Ed survey; 14 LED’s, aluminum body, 5.75″ long and uses 3 AAA’s inserted in a cage that goes into the body of the flashlight. They both seem to be solidly constructed – my kids were using them and I didn’t see any visible damage afterwards. Checked the batteries with a tester and they seem fine.

Bet you a buck the batteries are in backwards.
LEDs only pass current one way (and thus light up) – if the batteries are in backwards, no current will flow, and there will be no light (but you won’t destroy them either, cos a reverse-biased diode is just doing its normal job)
