Duracell Alkaline Batteries Ultra AAA (4 pcs.)

The unique powercheck technology allows you to check the energy level of the battery. It avoids unnecessary downtime and uses batteries that are no longer in use in more energy-intensive devices to power low-power devices (hold the batteries together and do not put them in another device with new batteries). Simply press the white dots on both ends of the battery and check its status on the meter. Duralock technology allows you to maintain the power of unused Duracell batteries for up to 10 years, as long as they are stored at ambient temperature. These are the best Duracell alkaline batteries for more energy-intensive devices, such as digital cameras, flashlights, power-hungry toys or bumboxes; they are also the ideal choice for standard devices such as powered toys, flashlights, wireless game controllers, razors, toothbrushes, etc.
