If you are looking for a rechargeable AA battery, then you may have found out aboth the eneloop and eneloop pro during your research. So, what are the main differences between these two Panasonic products?
You can find out in this comparison guide between the eneloop and eneloop pro AA-sized batteries.
When compared to the eneloop AA, the eneloop pro AA has a 27.5% bigger maximum capacity, which means that you can get more longevity with the pro version from a single full charge.
On the other hand, the eneloop AA has a much better storage life and can tolerate a higher number of charging cycles than the eneloop pro AA.
If you want to get the most usage time out of a fully charged battery, then we recommend getting the eneloop pro AA.
If you don’t mind having to recharging the battery more often, then the eneloop AA is the battery choice as you most likely won’t have to rebuy them as often as the pro verion.
