Well that's just not fair. I've had mine a couple years and used it very little. Tried AA and rechargeable 123 batteries. It works great for about 20 mins then cuts out. Sometimes I can get it to come back on with a smack but usually it's out until I recharge. I thought maybe it was a rattling on the bike/shorting problem but last night I put a freshly charged battery in (I've charged this battery 10x at the most) and left the light on, laid on a table. It lasted about an hour, then shut off.

So now I'm thinking I should call it a loss and get a 18650 torch, which could at least use the same charger.
