PGSONIC CR1620 3V Lithium Battery (5pcs) - Long Shelf Life

In this review of the PGSONIC CR1620 3V Lithium Battery (5pcs) the bottom line is straightforward: these batteries are best for small electronics that need steady, long-lasting coin cell power. The reviewer found them easy to install, reliably fresh on arrival, and particularly useful for devices where replacement is infrequent. The main reason to buy is the combination of a long guaranteed shelf life and safety features, which makes these batteries a practical choice for remotes, key fobs, medical devices, and small household gadgets.

Key Features

• Grade AA 3V: Supplies consistent 3 Volt output appropriate for a wide range of coin cell devices.
• Fresh with strong power: Each pack arrives fresh and delivers reliable energy for devices that need stable voltage.
• Premium performance: Designed to provide continuous power under varying temperature conditions for dependable operation.
• Long storage time: Holds 100% power for 5 years under good storage conditions, so spares stay ready when needed.
• Safety features: Leak-proof construction with 0% mercury and passing UN38.3 safety tests for safer handling and transport.
• Model equivalents: Compatible with CR1620, 1620, DL1620, and 1620H devices for easy replacement.

Who It's For

These batteries are aimed at owners of small electronics that require coin cell power: wrist devices, remote controls, car key fobs, glucometers, and other low-drain or intermittent-use gadgets. Users who want spares that can be stored for years without losing capacity will appreciate the five-year Best If Used By guidance on the package.

Those needing high-drain, continuous-use batteries for larger devices should look elsewhere, since coin cells like the CR1620 are intended for low to moderate current draw. Also, if a device specifies a different chemistry or voltage, choose the exact cell it calls for rather than substituting.

Pros & Cons

Pros

• Consistent 3V output that performs well in small electronic devices.
• Good value for a five-pack with fresh cells and practical storage life.
