FQ universal alkaline batteries are a reliable power source for frequently used devices that need increased battery power. Unlike standard salt batteries, they have a significant reserve of electricity and a low level of self-discharge, which will allow them to be stored outside the device for much longer. Where are used: computer devices (mice, keyboards, speakers), photographic equipment (photo-video cameras, flashes); remote controls; clocks and alarm clocks; medical devices; flashlights; portable speakers, players and radios; electronic toys, calculators. Attention! FQ batteries cannot be recharged.
