Re: Standardized rechargeable Li-Ion AA?

There is an extremely good reason why there is no Li-ion AA battery and there never will be. Li-ion batteries need special chargers as their electrolyte is highly flammable. An AA-sized Li-ion battery would run the unacceptable risk of being put into a charger designed for nikkel-metal hydride batteries with potentially disastrous results.

It's the same reason plugs and sockets for different voltages are designed to be incompatible, why your phone line can't be accidentally plugged into a mains power socket etc.
