Panasonic CR1620 3.0V Long Lasting Lithium Coin Cell Batteries - 4

In this review the Panasonic CR1620 3.0V lithium coin cell is assessed for everyday devices that need small, consistent power. The bottom line: it is best for anyone who wants a reliable, long shelf life button cell for remotes, key FOBs, watches and small medical or fitness devices, with the single biggest reason to buy being proven long storage life and stable output across temperature extremes. The pack reviewed contains four batteries in safety compliant, child resistant packaging intended to meet IEC and ANSI standards.

Key Features

• Long lasting performance: The CR1620 is engineered to deliver steady 3.0V output for small electronics so devices run reliably between replacements.
• Standards based safety packaging: The child resistant package meets or exceeds IEC 60086-4 and ANSI safety guidance to reduce accidental access in homes with children.
• Extended storage life: Unused cells can retain power for up to 8 years when stored properly, making them a good choice to keep as spares.
• Wide temperature reliability: These cells operate from about 14F to 140F, so performance stays dependable in varied household and outdoor conditions.
• Wide device compatibility: The CR1620 format fits many car key FOBs, watches, calculators, glucometers and other small devices commonly used daily.
• Manufactured by Panasonic: Production in a Panasonic Indonesia facility with U.S. packaging adds traceability and consistent quality control.

Who It's For

The CR1620 is ideal for homeowners, hobbyists, and anyone maintaining multiple small electronics who values long shelf life and reliable voltage under varied temperatures. It is particularly useful for car key remotes, watches, small medical devices and compact electronics that demand steady 3.0V coin cells.

Those who need extremely high-drain specialty cells or rechargeable solutions should look elsewhere; this is a primary, single-use lithium coin cell designed for long shelf life and steady discharge rather than high-rate rechargeable applications.

Pros & Cons

Pros

• Dependable 3.0V output that fits snugly in common coin cell compartments like remotes and watches.
• Long storage life of up to 8 years when unused, reducing the frequency of repurchasing spares.
• Child resistant, standards based packaging that follows IEC and ANSI safety guidance for household use.
• Reliable across a wide temperature range so devices keep working in various conditions.

Cons

• Single-use primary cell means extra cost over time compared with rechargeable alternatives for high-use devices.
