Product Details

The CR1220 Lithium Button Cell Battery is a small round lithium cell built for miniature low-drain devices that run on a 3V coin cell. It delivers a stable 3V output with a capacity of 40 mAh and a maximum discharge current of 1 mA, which matches the load profile of motherboard backup circuits and other micro electronics that draw a small, steady current over a long service period.

As stated in the product highlight, this is a 40 mAh CR1220 battery with a stable 3 volt lithium button cell construction, and it is a motherboard CR1220 button cell battery. The cell carries a 5-year shelf life and works over an operating range of -20 to 60 °C, so it can be stored and shipped through a wide range of climates.

WHY THIS PRODUCT 04

Product Advantages

  • Stable 3V Lithium Output: The cell holds a stable 3V lithium output, so motherboards and other 3V electronics receive the steady voltage they are designed for.
  • 40 mAh Capacity: A 40 mAh capacity in a CR1220 coin cell gives micro devices enough energy for the long, low-current service intervals they require.
  • 1 mA Max Discharge Current: A 1 mA maximum discharge current matches the design load of backup circuits and similar miniature devices, keeping the cell within its intended operating profile.
  • Wide Operating Range (-20~60 °C): The cell works from -20 to 60 °C, which covers normal indoor use in equipment and enclosures plus transport and storage through cold and hot climates.
  • Controlled Storage Conditions: Storage from -20 to 50 °C with 20 ±5 °C recommended as the best condition, so stock rooms and production lines can be planned around a clear temperature window.
  • 5-Year Shelf Life: A 5-year shelf life means stock can be produced, warehoused and distributed without tight rotation pressure.
