The Duracell rechargeable AA batteries have an impressive 2,500mAh energy capacity, which is great for powering any device. These batteries are also affordable, so you won't have to spend big bucks on becoming more economical! Something to keep in mind, however, is the pretty low recharge count of these batteries. While others can be recharged over a thousand times, Duracell's rechargeable batteries have a recharge count of only 400.
