Energizer 1616 Lithium Coin Battery, Long-Lasting 3V Power

In this review the Energizer 1616 Lithium Coin Battery is examined for users who need a dependable replacement cell for small electronics. The bottom line: this single-pack 3-volt lithium coin battery is best for people who want a compact, long-storage cell that works across a range of specialty devices, with the main reason to buy being its long shelf life and wide temperature tolerance. The reviewer found it particularly useful for key fobs, remotes, and health monitors where a reliable small cell matters.

Key Features

• Long storage life: Holds power for up to 10 years in storage so you can keep a spare battery ready for infrequent-use devices.
• Wide temperature range: Operates and stores across -22o to 140o F, useful for devices exposed to heat or cold.
• Broad compatibility: Cell size 1616 (IEC CR1616) fits many remotes, keyless entry systems, glucose and heart rate monitors, and toys.
• Dependable voltage: Provides a steady 3 volt output appropriate for specialty coin-cell electronics that expect lithium chemistry.
• Mercury-free design: Made without mercury, reducing disposal concerns compared with older button cells.

Who It's For

This battery is targeted at owners of coin-cell-powered items such as car remotes, key fobs, medical monitors, small toys, and game accessories who need a small, reliable replacement that can sit in a drawer for years. It is also a good option for people who keep emergency spares because the long shelf life and temperature resilience reduce the chance of a dead replacement when it matters.

Those who should look elsewhere include users who require multi-packs for frequent swaps or very high-drain devices; this single-pack offering is intended as a spare or occasional replacement rather than bulk supply for heavy users.

Pros & Cons

Pros

Cons

• Single-pack format is not ideal for users who need multiple spares at once.
