Hybrio batteries
The Hybrio batteries mix the best of disposables batteries (fully-charged out of the box) with the best of rechargable batteries (can be reused / recharged) whilst keeping the price down, which is the main reason that people continue to buy environmentally damaging one-use batteries.
A four-pack of fully charged Hybrios with a charger comes in at around £15, and each battery keeps 70% of its charge after a year, can cope with up to 500 charge cycles, and is protected by a three year limited warranty.
We've heard this whole song and dance before, but apparently Hybrios are such an improvement over regular one-use batteries that the Worldwide Wildlife Fund recently let the company stick its logo on the packets.
