Sanyo Eneloop AA 2550mAh 4 Pk (BK-3HCCE/4BT)

Despite they are more expensive but they perform better than other brands. It lasts longer and never a problem with leakage. I use them on GPS and other handheld equipment which battery leakage means end of life of equipment. Highly recommended to use on expensive gadgets.

My original 4 x Eneloop 1900 mAh batteries still work just as good as ever after more than 1000 recharges. This time I bought the 2450mha batteries which will give an even longer run time than the 18 hrs with the old type. New ones only rated for 500 recharges, so don't know how this will pan out, but trust the product. Fingers crossed.
