As with most information on the internet: Caveat Emptor. I would say, "It's worth every penny you're paying for it." "God gave you a brain and expects you to use it." So you're implying that only expensive things are worth whil? How about, for example, air - or water. I have found much better informaion on the internet than from sales people - they generally don't even know what they are selling, and if they do they have a vested interest. |

There is often far more crap on the Internet than valid info, and it can be very difficult to tell the difference. When you're paying for information, you get the benefit of screening by someone trained to tell the difference. That's why, for example, Bloomberg makes so much money. Sales people are of course another matter entirely, since they are being paid to influence you. -- Best regards, John Navas Panasonic DMC-FZ8 (and several others) |

"safe" temperatures for lithium batteries?

I am guesing its a lithium-ion in my case. The reason I ask is that I left the item near a source of warm air (computer system fan) and it got quite warm to the touch when I finally moved it. it would just be nice to have some actual figures for what constitutes a risky temperature for rechareable li-ion batteries... Some info is available in the manuals that are provided with the cameras that use Li-Ion batteries. FWIW, the manuals for several of the ones I've downloaded (Canon, Nikon, Olympus, etc. - you don't need to buy cameras to download the manuals) all specify the same operating temperature range of 0 – +40 °C (+32 – 104 °F). Unfortunately, they don't mention recommended storage temperature ranges, which will be somewhat wider. You might be able to get this information from battery manufacturer's data sheets. The ones provided by Energizer for their non-rechargeable lithium AA and AAA batteries shows that they far surpass the recommended range of the rechargeable Li-Ion batteries, although by how much on the hot end I can't say, and this won't help you with your current batteries. [For Energizer's L92 (AA) lithium cells] : Storage Temp: -40°C to 60°C (-40°F to 140°F) Operating Temp: -40°C to 60°C (-40°F to 140°F) |
