Whoever values quality chooses a 9-volt block battery from the "Super Alkaline" series from GP. A particularly powerful battery with endurance. Ideal for devices where you don't want to change the battery again after a short time, for example smoke detectors. Game controllers and electric toys also often need a 9-volt block, as do wireless microphones and headphones, fire alarms, metal detectors and radio-controlled toys. All these devices work perfectly with GP Super Alkaline batteries. The package contains 8 pieces. The 9 volt alkaline battery from GP with the designation 1604A is suitable as a replacement for batteries with one of the following designations: 9V, E-Block 6LR61, 522, 6LP3146 and MN1604. https://elecena.pl/product/19752194/030e1604alb8-alkaline-battery-9-v-8-pcs 2021-10-30 https://elecena.pl/product/19752194/030e1604alb8-alkaline-battery-9-v-8-pcs 2022-05-30 https://elecena.pl/product/19752194/030e1604alb8-alkaline-battery-9-v-8-pcs 2022-11-16 https://elecena.pl/product/19752194/030e1604alb8-alkaline-battery-9-v-8-pcs 2025-08-18
