MAPLINS sell these,http://www.ebay.co.uk/itm/Nickel-Zi...h-Batteries-/191472545667?hash=item2c94a72f83 they are fantastic 1.6 V I use them in my camera and they just keep on going PS you need the dedicated charger though but well worth it they are nickel zinc

They look the biz.
Some yeas ago, my sons had some radio-controlled cars that used 8 AA cells. I replaced them with NiCd and the cars went like rockets, but not for long. The radio receivers were the weak link - they went deaf when the voltage dropped, so, although the cars would still have amps for the motors, there were not enough volts for the RC.

Eneloops are the only rechargeables I'd consider these days.

Eneloops are good. They are low self discharge, which is great for things which you don't use all that much, like a torch or a camera. Very often with such things you lose more charge through self-discharge over a month or two than through use, so you find yourself recharging even if the item hasn't been used much. Cheap NiMH are notorious for high self-discharge. However, for something which is charged and discharged every day, like the battery in a set of solar garden lights, Eneloops have no advantage.
