Product catalog summary

Type Designation and Specifications
The CoinPower CP 1254 A3 is a lithium-ion battery with a cell code of ICR1254 and a system composition of graphite-layered metal oxide (LiNixMnyCozO2). It has a nominal voltage of 3.7V and a nominal capacity of 60mAh, with a typical capacity of 63mAh.

Dimensions and Weight
The battery has a diameter of 12.1mm, a height of 5.4mm, and weighs approximately 1.6g.

Charging Method and Parameters
The battery uses a constant current plus constant voltage charging method with a charge voltage of 4.20V ± 0.05V. Initial charge currents are 30mA for standard charge, 60mA for fast charge, and 120mA for rapid charge. Charging cut-off can be by time (5 hours for standard, 3 hours for fast/rapid) or by minimum current (1.2mA).

Discharge and Operating Conditions
The discharge cut-off voltage is 3.0V. The maximum pulse discharge current is 180mA for 2 seconds, and the maximum continuous discharge current is 120mA. Operating temperatures range from 0 to 45°C for charging and -20 to 60°C for discharging.

Storage and Cycle Life
The battery retains over 90% capacity after 1 year at -20 to 20°C, over 90% after 3 months at -20 to 45°C, and over 85% after 1 month at -20 to 60°C. It has an initial impedance of less than 0.5Ω at 1kHz and a cycle life of over 500 cycles at 0.5C/0.5C, maintaining more than 80% of initial capacity.

Safety and Compliance
The battery has passed UN 38.3 and IEC 61233 safety tests. It also passed internal overcharge tests at 12V, 3C, 12h, and 5V, 1A, 12h.

Recommendations and Patents
The battery must be used with external safety electronics (PCM) and is intended for specific purposes. For medical applications, contact VARTA Microbattery. The product is protected by multiple patents, including US and EP patents.
