Duracell Optimum AAA batteries provide up to 100% extra life and extra power (compared to the Minimum Average Duration of the 2015 IEC Digital Camera test. Results may vary by device or usage).
Extra Life
Duracell Optimum will last longer than previous Duracell Alkaline batteries in a range of mid to high drain devices (e.g. Xbox One Wireless Controller, Fujifilm Instax mini 11 camera).
Extra Power
In other devices, Duracell Optimum will deliver more power than previous Duracell Alkaline, making them work better (running motors faster in remote controlled cars). So your screwdriver can operate with more power to build your DIY furniture faster
