Hello to you, About ENELOOP rechargeable batteries (available from SANYO), I am now little more than this brand, either AA or AAA. they are very easy to spot without having to read it, since they are white! Their fault? they are MORE EXPENSIVE than other brands. Their interest? LITTLE they have to "memory effect" (in fact, according to my Assemblers in whom I have confidence, ALL BRANDS have more or less a "memory effect". ENELOOP also. But this brand is still very well placed. So... Conclusion: since I am very satisfied with this brand, I do not see why I would change, even under the pretext of (this remains to be demonstrated) savings. I prefer to bet on tranquility.
