AA NiMh Rechargeable Batteries NEW LSD Technology 2500mAh.
The batteries are supplied charged, so just use them straight after purchase. The LSD Vpaextech batteries discharge at a much slower rate than conventional NiMH batteries, so even a year after being charged there is still lots of the initial charge available. You get the benefits of traditional NiMH rechargeable batteries, without the drawbacks. You can still use a standard NiMH charger to charge them up again. So its like having a Alkaline battery that you can charge!
