Even saved a battery on a bike i bought from a friend that was completely depleted of power. It is still holding a charge 1.5 years later. Dont need often but when i did it performed flawlessly. ### ⭐⭐⭐⭐⭐ Great brand, always works as expected *by on Reviewed in the United States July 26, 2026* Saved a completely dead battery in a few hours. Been using this brand for a decade and never fails except my old version that was for acid battery adhd said to be compatible with others doesn't work for the lithium when totally dead. Battery sat on bike dead for 7 months, this totally did the job ### ⭐⭐⭐⭐⭐ Revives expensive lithium ion batteries!!! *by on Reviewed in the United States August 27, 2026* I bought this to save the dead lithium ion battery in my 2025 Husqvarna TE150. The other lithiom ion tender I was using previously was not able to charge the battery because it had gotten so drained that the ECU put it in sleep mode. The Optimate slowly brought it back to life and saved the battery! I'm so happy I purchased this! ## Frequently Bought Together - OptiMATE Lithium 4s 0.8A, TM-471, 8-step 12.8V 0.8A sealed battery saving charger & maintainer - Antigravity ATZ-10 Performance Lithium Motorcycle Powersport Battery with Built-In Jump Starting. 6.1Ah, Replaces YTZ10, YTZ12, YTZ14, YTX9, YTX7A Yamaha, Honda, Kawasaki, Suzuki --- ## 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://congo.desertcart.com/products/17483206-tm471](https://congo.desertcart.com/products/17483206-tm471) --- *Product available on Desertcart Congo* *Store origin: CD* *Last updated: 2026-10-14*
