Description

CR1616 Batteries

• The CR1616 is a primary (non-rechargeable) lithium manganese-dioxide (Li/MnO₂) coin cell.

• Its naming indicates its size: “16” → 16 mm diameter; “16” → ~1.6 mm thickness.

• Typical voltage is 3.0 V nominal.

• Typical capacity ranges around 50 mAh (some up to ~60 mAh depending on manufacturer and load).

• Dimensions: ~16.0 mm diameter × ~1.6 mm thickness.

Key Features & Benefits

• Compact size: Very thin, making it ideal for devices with limited space.

• Stable 3 V output: Useful for many small electronics requiring that nominal voltage.

• Long shelf life / low self-discharge: For example, self-discharge is around ~1% per year in some specs.

• Wide temperature range (depending on maker): Some versions specify operation down to -30 °C or up to +85 °C.

• Versatile low-drain usage: Excellent for devices that draw small current for long periods (e.g., watches, key fobs).
