tr-3t6, bad to let light run until light dies?

i’m using xtar 3100’s. is running the light until the light goes out bad for the batteries?

Which light ?

If your torch has low-voltage cutoff set high enough (~3.0v) then doing so repeatedly will only shorten the cell’s lifespan and capacity a moderate amount.

If you are counting on the cell’s low-voltage protection circuit to indicate the need for recharging (~2.5v, IIRC) then it will have a much greater impact on both cell longevity and capacity after cycling the cell often in such a manner.

it’s the trustfire TR-3t6

According to the review here, it doesn’t have low-voltage cutoff.

I wouldn’t run it until the cells trip, since the driver seems to be buck/boost.
