Rock solid performance from the name you know and trust! Energizer rates these rechargeable AA batteries at a conservative 2450mAh, yet in our testing, these Energizer batteries consistently provided 15-20% longer run-times than similarly rated batteries offered by the likes of Sony, Ansmann, Lenmar, & CTA. In an industry that routinely overstates the useable capacity of batteries, these Energizer rechargeable AA batteries actually deliver performance very close to their rated capacity.
Actual tested capacity*: 2395-2449 mAh
*Capacity testing has been performed with the PowerEx MH-C9000 WizardOne Charger/Analyzer which follows the IEC standard for determining battery capacity. Testing was performed on a random sampling of 4 individual Energizer 2450mAh rechargeable AA batteries and the results published above are an average of several tests. Your own results may vary.
