URC-LOG880 Replacement Battery for Harmony 880 Remote - Reliable Power

In this review of the URC-LOG880 Replacement Battery for Harmony 880 Remote, the bottom line is simple: this is a straightforward, no-frills lithium ion replacement intended for owners of the Harmony 880 who need a like-for-like power pack. The reviewer found it installs easily and restores remote functionality quickly, making it a sensible choice if the original battery has weakened. The single biggest reason to buy is compatibility and correct voltage: a 3.7V, 950mAh pack that matches the original specification and gets the remote back to regular use without fuss.

Key Features

• Exact voltage and capacity: The 3.7V and 950mAh rating provide the correct power output for the Harmony 880 and helps avoid compatibility issues that can arise with generic replacements.
• Lithium ion chemistry: Offers a compact, rechargeable cell type that balances energy density and size so the battery fits the remote housing precisely.
• Compact package size: The thin profile and small dimensions make it easy to fit into the remote without forcing or modification to the case.
• Plug-and-play replacement: Customers report the battery restores functionality immediately, reducing downtime and the need for technical support.
• Imported component: Country of origin CHINA, which is typical for replacement cells and allows for cost-effective sourcing.

Who It's For

This battery is for Harmony 880 owners who want a direct replacement that mirrors the original pack in voltage and capacity. It is suited to users comfortable swapping a small rechargeable cell into a remote housing and who prioritize restoring normal function over upgraded features like higher capacity or smart battery management.

It is not for users seeking a dramatic increase in runtime or advanced battery features; some customers report mixed feedback on longevity, so those needing extended life between charges should consider alternatives or expect performance similar to the original specification.
