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.

Quick Summary

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.

Chemistry

When it comes to the chemistry, the regular and pro versions of the eneloop AA batteries are composed of LSD Ni-MH.

Capacity

The eneloop pro AA has a 27.5% bigger maximum capacity when compared to the eneloop AA. As a result, you should be able to get more usage out of a fully charged eneloop pro battery than a fully charged eneloop battery.

You can find the capacity specs for both below:

  • eneloop AA: 1900 mAh to 2000 mAh
  • eneloop pro AA: 2500 mAh to 2550 mAh

Storage Life

On the other hand, the eneloop AA has a much better storage life than the eneloop pro AA.

For the uninformed, storage life measures how capable a battery is when it comes to holding a charge after not being used for a certain length of time.

The eneloop AA battery is able to hold a 90% charge for up to 1 year as well as a 70% charge for up to 10 years. The eneloop pro AA battery is able to hold an 85% charge for up to 1 year.
