Tired of AA's...

[J57ltr]

OK, date with the wife got in the way of testing, but here are my results. This is in the TQ3 I have, have to wait till John comes back over to see what a TQ2 will do, but I don't expect any difference except for normal manufacturing tolerances.

At 8.03V the light starts to flash.
At 4.2V it starts to dim while flashing.
At 3.353V it's really dim and still flashing.
At anything under 3.25V it completely shuts off.

To test this I had to use an old Protoboard with built in power supply 0-15V. The meter I used is a Fluke 112. I did both rising and falling voltage to test hysteresis 3 times.
