CR1616 3V Lithium Coin Cell Battery

CR1616 3V Lithium Coin Cell Battery (Cross-Reference: CR1616 / DL1616 / ECR1616 (IEC 16mm × 1.6mm)) is a primary (non-rechargeable) lithium manganese dioxide (li/mno2) miniature cell providing a stable 3.0V DC nominal output and ~50 mAh to 55 mAh capacity. Engineered with a leak-resistant stainless-steel crimp seal and low self-discharge chemistry, it delivers reliable long-shelf-life power for ultra-slim car remote key fobs, Casio/digital wristwatches, Game Boy cartridge SRAM backup, and compact medical sensors.

Key Features:

• Precision 3.0V Nominal Output: Maintains a flat, dependable discharge voltage curve suitable for CMOS memory retention, RF transmitters, and LCD measuring instruments.
• Universal IEC Size & Cross-Compatibility: Matches standard CR1616 / DL1616 / ECR1616 (IEC 16mm × 1.6mm) mechanical dimensions (Ø16.0 mm × 1.6 mm) for drop-in replacement.
• Leak-Resistant Crimp Seal: Nickel-plated stainless-steel can and polypropylene gasket prevent electrolyte leakage inside delicate watches, calipers, and remote controls.
• Extended Shelf Life: Low internal self-discharge preserves energy during multi-year storage at room temperature.
• Mercury-Free Eco-Safe Formulation: Manufactured without added mercury or cadmium for safe everyday consumer and industrial use.
