Panasonic CR1620 3.0V Lithium Coin Cell Batteries - Long Lasting

In this review the Panasonic CR1620 3.0V coin cell is assessed for everyday devices that need a reliable, compact power source. The bottom line: this two-pack is best for owners of car key FOBs, small remotes and watches who want long storage life and safety-conscious packaging. The reviewer found the cells deliver consistent voltage, simple installation, and the child resistant, standards-based packaging provides extra peace of mind for households with children.

Key Features

• Long lasting performance: The CR1620 offers steady power output for devices that require 3.0 V nominal voltage, reducing the need for frequent replacements.
• Child resistant packaging: The standards-based, child resistant package meets multiple safety norms so batteries are less accessible to children.
• Long storage life: Unused cells maintain charge for up to 8 years when stored properly, making them good to keep in a drawer for emergencies.
• Wide temperature range: These batteries remain dependable across a broad operating range (14F to 140F), suitable for devices used indoors and in varied climates.
• Broad device compatibility: The CR1620 fits many household items such as car key FOBs, watches, calculators, and small medical devices, so one pack covers multiple needs.

Who It's For

The Panasonic CR1620 is aimed at people who need a small, reliable coin cell for car key remotes, watches, garage door transmitters, and compact electronic gadgets. It is especially appropriate for purchasers who value verified safety packaging and long shelf life so spares can be stored without worry.

People who need larger batteries, specialty rechargeable cells, or high-capacity cells for continuous heavy-drain devices should look elsewhere. This pack contains two non-rechargeable cells, so it is not intended for products that demand rechargeable or higher-current solutions.
