Petzl Warnings About LED's and Lithium Batteries
Petzl have issued a warning about Lithium batteries potentially damaging the LED's in some of their products.
I've no idea if the same will apply to other LED torches, but to be on the safe side you should contact your manufacturer if you are thinking of using Lithiums in your torch. Posted by bigcrags @ 4:46 PM

Hello I have read these comments with interest and wanted to flag up some important points to you about the use of Lithium in headtorches. The statement on the Petzl website claims that lithium batteries have a higher output during discharge which can cause the lamp to overheat. In a device Lithium batteries put out the same amount of power as regular batteries – the technology just allows the battery to do it for longer. We have not seen any technical evidence to support Petzl’s claim and we have had no other issues or complaints regarding the performance of Energizer Ultimate Lithium in headtorches. Energizer Ultimate Lithium performs extremely well in extreme temperatures (below 0 degrees), giving a better performance to users of headtorches in cold conditions. Lithium batteries are often best known for their performance in high-drain devices such as digital cameras and MP3 players, but also in high performance torches. Below are a few key points about Energizer Ultimate Lithium. Energizer Ultimate Lithium • Performs well in extreme temperatures (from -40°C to +60°C) • 33% lighter than alkaline AA • The world’s longest lasting AA battery in high-tech devices • Lasts up to 7 X longer in digital cameras* • Takes up to 630 pictures** in a digital camera vs 90 photos with an alkaline battery • Carries a 15 year shelf life • Lasts up to 5.5 hours longer than leading ordinary alkaline batteries in MP3 players • Up to 12 CD player hours * Based upon ordinary alkaline in proposed industry testing. Results may vary by camera ** NCIEC digital camera test, results may vary by camera Elizabeth McGregor Marketing Director Energizer UK # posted by
 : 4:13 PM Hi Elizabeth, There's no doubt about the performance of Lithium batteries. Indeed, the cold of the winter mountains, it can sometimes be the only battery that will keep a digital camera going all day. Thanks for filling us in with the facts and figures. Much appreciated. Adam << Home
