PKCELL CR1620 3V 70mAh Lithium Button Cell Battery

Coin Cell for Key Fobs and Memory Backup

The PKCELL CR1620 battery is a 3.0 V lithium manganese dioxide coin cell rated at 70 mAh. It measures 16.0 mm across and 2.0 mm thick. The cell powers car remotes, watches, CMOS memory circuits and small medical devices.

Open-circuit voltage sits between 3.05 and 3.45 V at 23 °C. Under a 47 kΩ load the terminal voltage holds 3.00 to 3.45 V after five seconds. A continuous 47 kΩ discharge to a 2.0 V cut-off runs 630 hours nominal and 560 hours minimum.

Operating temperature spans -20 °C to 60 °C, and storage stays at 25 ± 15 °C. Self-discharge holds below 5% across twelve months on the shelf. The cell weighs 1.6 g and contains no mercury, cadmium or lead.

Key Features

• Lithium Manganese Dioxide Chemistry
  The Li-MnO2 system delivers a stable 3.0 V plateau across most of the discharge curve.

• 70 mAh Rated Capacity
  Capacity is specified at 47 kΩ continuous discharge to a 2.0 V endpoint at 23 °C.

• Voltage and Discharge Envelope

  • Open-circuit voltage of 3.05–3.45 V at 23 °C.
  • Load voltage of 3.00–3.45 V under 47 kΩ after 5 seconds.
  • Fast discharge at 4.7 kΩ reaches the 2.0 V cut-off in 63 hours.

• Low Self-Discharge
  The cell loses less than 5% of capacity over twelve months at normal storage conditions.

• Primary Non-Rechargeable Cell
  The chemistry carries no memory effect, so partial discharge does not shorten service life.

• Compact 16.0 x 2.0 mm Case
  A 2.0 mm profile fits slim compartments in remotes, watches and sensor housings.

• Sealed Leak-Resistant Body
  The crimped stainless case passed a 30-day 45 °C leakage test with no electrolyte escape.
