Energizer, the manufacturer

of batteries and torches, is

conducting a second wave of marketing for its Ultimate Lithium battery, which the company says is the world's longest-lasting battery in hi-tech devices.

It is capable of powering

a digital camera for 600

photos compared with 90 when using a standard alkaline

battery, and lasts 5.5 hours in

an MP3 player.

Energizer is giving three

lucky retailers the chance to

win two boxes of Energizer Ultimate Lithium 4xAA batteries.
