I am new to this website. I use almost entirely 123A rechargeables for my torches. I think the word to always remember is "SAFETY".
Most 123As, and in fact, AAs, AAAs, Buttons and the lot, are now made in China. Yes, even the big names such as Duracell and Energizer are no exceptions.
I think the following guidelines, many based on earlier views expressed in this thread, should be seriously observed.
1. Never mix batteries of different brands or of different degrees of exhaustions.
2. Change or recharge entire sets once the light becomes dimmer. Don't wait until the light goes out or by trying to turn to a lower setting and wait till the light dims out completely.
3. Try not to turn your light on for longer than necessary. Always turn off when they become hot. If you need to use a light for longer periods, best to carry two or more lights and use them in turn.
4. Check your batteries weekly, or sooner, and everytime before you go out intending to use the lights. Check for leakages and indents at top and bottom. Some designs which turn on the light by turning the tailcap, e.g. 6P, can cause the batteries to be too tightly squeezed. Given time this may cause indents. especially with cheaper Chinese torches.
5. Take care where you leave your lights normally. If you have a light in the kitchen, as in the case in this thread, keep clear of the oven ,cookers, tabs and any known sources of heat and water. And, like drugs, keep out of reach of children (and dogs and cats).
Accidents can always happen. The name of the game, however, is to take all necessary precautions so as to avoid them. An instrument can always be dangerous if the master of it is not too careful.
I hope I have been of some help.
