The indicator clearly shows whether the battery is charging or maintaining. Feels like a high-quality product. Review: Buy this and toss the rest - I sure wish I knew what I know now 10 years ago. 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 ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07NSKTNKX | | Amperage | 10 Amps | | Battery Charge Time | 120 minutes | | Best Sellers Rank | #874,799 in Automotive ( See Top 100 in Automotive ) #1,637 in Battery Chargers | | Brand | Tecmate | | Color | Blue, Multicolor | | Connector Type Used on Cable | Alligator Clips, SAE Connector | | Current Rating | 10 Amps | | Customer Reviews | 4.8 4.8 out of 5 stars (34) | | Input Voltage | 120 Volts | | Item Weight | 1.41 Kilograms | | Manufacturer | Tecmate | | Mfr Part Number | TM-275 | | Model Number | TM-275 | | Number of Ports | 1 | | Output Voltage | 12.8 Volts (DC) | | Specification Met | CE | ## Product Details - **Brand:** Tecmate - **Color:** Blue, Multicolor - **Item Weight:** 1.41 Kilograms - **Output Voltage:** 12.8 Volts (DC) - **Specification Met:** CE ## Images ![Optimate Lithium 4s 10A, TM-275v2, 10-Step 12.8V 10A Sealed Battery Saving Charger & maintainer - Image 1](https://m.media-amazon.com/images/I/81wxtwbB0mL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ High quality *by B***. on May 5, 2025* Great charger—reliable, easy to use, and completely hassle-free.

Feels like a high-quality product. ### ⭐⭐⭐⭐⭐ Buy this and toss the rest *by B***A on March 21, 2023* I sure wish I knew what I know now 10 years ago. 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 ### ⭐⭐⭐⭐⭐ The most reliable and easiest to use charger brand *by C***0 on May 5, 2021* Don’t waste your time with other chargers. These are plug automatic and they actually work. I’ve seen and recovered batteries that other brands like CTEK and Noco have failed to recover. ## 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.pl/products/112093095-optimate-lithium-4s-10a-tm-275v2-10-step-12-8v](https://www.desertcart.pl/products/112093095-optimate-lithium-4s-10a-tm-275v2-10-step-12-8v) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-04-22*
