I've used this battery for a month now and so far no issues, in fact is seems to last longer than the previous battery (Which is probably due to a defective battery). 10/22/13 Update to my review, I felt compelled to write a follow up since I've seen so many negative reviews. I've used this battery for almost 3 years now with no issues and am really surprised on how many people had defective batteries. Maybe I've been lucky but I've noticed I can't go more than a couple of days on a single Charge (Which happens due to aging battery) but that's been OK since we put the remote back on the charger by the end of the day. I haven't had a problem with the stock charger charging the battery nor have I had the pleasure of this battery failing. Review: Perfect for Logitech - Had a Logitech Harmony all in one remote. Sadly they have stopped producing them. Ours was acting strange rebooting not turning on devices. Replaced the original battery with this one and it’s good as new. ## Features - Kastar Battery Replacement for Logitec R-IG7 Battery - Battery Type: Lithium-Ion; Battery Voltage: 3.7V - Battery Capacity: 950mAh - Package Includes: 1 Battery - Compatible: Logitech Harmony One, Harmony 900, Harmony 880, Harmony 890, Harmony 720, Harmony One Advanced, Harmony 890 Pro, NTA2340, Logitech R-IG7, Harmony 880 Pro, Harmony 895, Logitech 190304-2000, Harmony 885, Logitech 190304-0000, Harmony 785, Logitech F12440023, Logitech 815-000037, Monster AVL300s, Harmony H880, Logitech 190304-200, Logitech K43D, Logitech M36B, Logitech M41B, Logitech 866165, Logitech 866145, Logitech 866207, Monster AVL300, Monster MCC, Monster AV100, Harmony HR880 Pro ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B003YJAXEM | | Batteries | 1 Lithium Ion batteries required.

Sadly they have stopped producing them. Ours was acting strange rebooting not turning on devices. Replaced the original battery with this one and it’s good as new. ### ⭐⭐⭐ AEC Review *by A***N on August 16, 2012* The rechargeable battery worked great upon arrival when I installed the unit. Now I need to purchase a new battery, because for some reason the battery wil not hold a charge long. Amazon's service was good, however; the suppliers service/product was not to good, for me. ## Frequently Bought Together - Kastar Rechargeable Battery Compatible with Logitech Harmony 880 890 720 785 885 895 One MX-880 R-IG7 F12440023 815-000037 190304-2000 190304-0000 866165 866145 866207 and Monster AVL300 MCC AV100 - Logitech Harmony Remote Control Replacement Rechargeable Battery - Harmony One, Harmony One Advanced, Harmony 720, 850, 880, H880, 880 Pro, 885, 890, 890 Pro, 900, 900 Pro, Harmony 1, Harmony 1 Advanc --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.th/products/12047546-rechargeable-battery-compatible-with-logitech-harmony-880-890-720-785](https://www.desertcart.co.th/products/12047546-rechargeable-battery-compatible-with-logitech-harmony-880-890-720-785) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-04-27*
