TECHNOLOGY
Longer life, trusted reliability
Maximize the long-lasting power in every device with eneloop pro. These rechargeable battery cells feature a unique formula that deliver up to 20% more capacity than eneloop batteries. eneloop pro batteries also maintain stable voltage until the battery charge is depleted. Your devices work longer, and you save more with every charge.
*Testing method established by IEC 61951-2 (7.3.2) and compared with minimum capacity.
Note: The graph opposite shows an AA-size eneloop pro tested against an AA-size eneloop and a competitive AA-size alkaline battery under continuous discharge at 500 mA, 25 °C. Values are approximate.
Faster flash charging and longer life
External camera flash units demand short, strong bursts of power, requiring time for their capacitors to be refilled. That delay could make you miss the shot of a lifetime. eneloop pro batteries refresh your flash much faster than regular alkaline batteries. Flash units powered by eneloop batteries can even be set to burst mode, allowing users to capture life’s most important moments.
Note: According to Panasonic research with 4x AA eneloop pro tested against 4x AA eneloop and 4x comparable AA alkaline batteries in an auto-flashing strobe with a 2-second flash interval and 10 minutes rest every 20 seconds. Recharge time is measured every 100th flash.
Retains up to 85% of its charge after 1 year*
We've improved the metal-hydride alloy lattice inside your eneloop pro battery so that it retains up to 85%* of its charge even after 1 year*, when unused and properly stored. The design also resists voltage drop during discharge and minimizes loss of capacity. You can trust eneloop pro Ni-MH rechargeable batteries to provide long-lasting, stable power to all power hungry devices.
*Capacity based on testing method established by IEC 61951-2 (7.3.2) when stored at 20 °C (based on Panasonic's estimation) and compared with minimum capacity. Varies according to conditions of use and proper storage.
Pre-charged with solar energy and ready to use
eneloop pro batteries are initially charged at the factory using power generated from solar energy.** The Panasonic Environment Vision 2050 initiative, is focused on generating more energy than we use by 2050. Pre-charging eneloop pro batteries means you can use the cells immediately after purchase.
