CR2450 Battery 3V Lithium Coin Cell - 5 Pack for Key Fobs

In this review the reviewer looks at the CR2450 3V lithium coin cell in a 5 count pack and finds it a practical, value-oriented replacement for small electronics. The bottom line: this pack is for anyone who needs reliable power for key fobs, remotes, calculators or garage door openers and wants a long shelf life and an anti-leak design. After testing fit and temperature tolerance, the reviewer found the cells offer convenient long-term storage, wide operating temperature range, and good compatibility with several equivalent sizes.

Key Features

• Pack size: Five CR2450 cells provide spare batteries so users can replace multiple devices or keep extras on hand.
• Wide compatibility: These cells fit devices that accept DL2450, ECR2450, GPCR2450 and other equivalent sizes, reducing the need to guess fit.
• Temperature tolerance: Rated to perform from about -4 F to 140 F, so they keep working in cold cars and warm environments.
• Long storage life: Lithium chemistry and a claimed shelf life of up to 10 years mean the pack is useful as a long-term spare supply.
• Anti-leak design: Improved sealing reduces the risk of corrosive failure in sensitive devices over time.

Who It's For

This CR2450 5 pack is best for homeowners and vehicle owners who regularly change batteries in key fobs, remote controls, thermometers, and small electronics and want spare cells on hand. It suits DIYers who maintain multiple devices or service kits for property managers and technicians.

Those who should look elsewhere include users who need specialized rechargeable cells or batteries with proprietary branding where official OEM parts are required for warranty reasons. Also, if precise runtime claims are critical, a dedicated performance test of any given device will be necessary rather than relying on general longevity statements.

Pros & Cons
