I wasted so much money on about 4 other chargers with low amps before. This is the level of charger I needed all along to charge my dead Li batteries when I was replacing them. Now I have 3 useless chargers and 2 Li batteries that are good again just sitting around lol ## Frequently Bought Together - Optimate Lithium 4s 10A, TM-275, 10-Step 12.8V 10A Sealed Battery Saving Charger & maintainer - Optimate 7 Select - 12V 10A, TM-251v3, 9-Step Gold Series Battery Saving Charger & maintainer --- ## 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.ro/products/593078521-tecmate-optimate-lithium-4s-10a-tm-275v2-10-step-12](https://www.desertcart.ro/products/593078521-tecmate-optimate-lithium-4s-10a-tm-275v2-10-step-12) --- *Product available on Desertcart Romania* *Store origin: RO* *Last updated: 2026-08-13*
