Lithium-coin type lithium batteries are high-energy, high-reliability batteries for a wide range of applications. The full 3V voltage of these high-energy-density batteries is about twice that of conventional dry batteries. There are two types of lithium lioning batteries: lithium polyfluorofluorinated influenzae (BR series) for uses that require greater reliability and safety, and lithium manganese dioxide batteries (CR series) for uses that require high voltage and strong load pulse characteristics. Let`s talk about BR1225, The BR1225 is a 3V / 48mAh coin cell non-rechargeable battery with lithium polymer technology and pressure contact terminals. Coin-type lithium batteries are high-energy, high-reliability batteries for a wide range of applications. The full 3-volt voltage of these high-energy-density batteries is about twice that of conventional dry batteries. Panasonic coin lithium batteries are polycarbon monofluoride lithium batteries (BR series) for uses that require greater reliability and safety. BR1225 can be customized for additional processing, add solder chip terminals, insulation packaging and configuration type, the model as following: BR1225/H1AN, BR1225/H9AN, BR1225/HAN, BR1225/VFN, BR1225/HBN, BR1225/HCN, BR1225/VCN.
