Next generation rechargeable batteries: robust & lightweight

The CoinPower® series from VARTA Microbattery are lightweight lithium-ion rechargeable micro batteries featuring 3.7V with a maximum capacity of 120mAh. The energy density is up to 30% higher than comparable products, therefore these lightweight button cells are suitable for Bluetooth, portable, and wearable technology applications. These button cells are free of lead, mercury and cadmium.

The CP 1254, CP1454 and CP 1654 feature capacities of 60, 85 and 120mAh respectively and boast low impedance, an extended shelf life of > 1 year, and fast charge capability. Certified to IEC 62133/UL 1642 safety standards, these batteries offer optimized drain capability (CP 1654 up to 500 mA continuous) and may be recharged over 500 full cycles while maintaining at least 90% initial capacity. The cells use the CC/CV (constant current-constant voltage) charging method and exhibit virtually no swelling due to their scratch-resistant stainless steel enclosure. These button cells are available as Crimptag Wires for proto typing, as Bare Cell and various solder tags assemblies for Mass Production.
