Innovative function for your safety
FDK coorporation, producer of FUJITSU batteries range works continuously on new technologies to ensure safe usage of its products.
One example of its innovation and valuable know-how is achieving greater safety through reverse current prevention in FUJITSU alkaline range. FUJITSU LR20 (D size) and LR14 (C size) alkaline batteries are equipped with special resin projections on the negative face. These prevent two negative terminals from touching each other, so the current will not flow when one or more batteries are improperly inserted.
