TOP-TECH: Rechargeable battery
Error processing SSI file

Laptop computers, digital cameras, mobile phones, portable MP3 players - they all depend upon lightweight rechargeable batteries. Without them, none of these devices would exist as they do today.

Make no mistake, all of these devices could use non-rechargeable batteries, but the cost would be very high and the waste created by used batteries would severely damage the environment.

So to meet the power demands of today's portable devices we have rechargeable ion batteries.
