The UPS recognizes them and works flawlessly. I'll see how long they last and update if they don't hold up. Outside of longevity, they are much lighter then the SLA batteries and keep the devices plugged into the UPS online longer, as well (using the same load/devices as the SLA batteries).

The UPS recognizes them and works flawlessly. I'll see how long they last and update if they don't hold up. Outside of longevity, they are much lighter then the SLA batteries and keep the devices plugged into the UPS online longer, as well (using the same load/devices as the SLA batteries). ### ⭐⭐⭐⭐⭐ Battery *by J***I on February 5, 2026* Battery fitment was good, hold charge for a good while, good value ### ⭐⭐⭐⭐ Misleading Advertisement, But Good Product *by T***K on October 10, 2022* This battery is good for some things, but not all things that are shown. A single battery is rated at about 100W constant output and about 255w for 5 seconds. The correct use for this battery is as a short term UPS backup on smaller items like LED lighting, laptops, Wifi routers and cell phone chargers. Incorrect use would include, motors (tools, ride on toys, golf carts. starter motors) medium to large solar storage...any other high current uses (>100W per battery) This battery is designed for a slow and steady output unlike a car battery that is designed for high output for short amount of time. DC motors have a high starting current, over 15 times the run current. Think about all the start/stops on a tool or toy ride on. All that being said, under correct usage (>=1C) the batteries performs much better than lead-acid with a 24v UPS load of 175W AC for 48 minutes vs about 35 minutes before low voltage cutoff. It will be some time before I can comment on the longevity of these batteries. ## Frequently Bought Together - NERMAK 12V 7Ah (7.2Ah) Lithium LiFePO4 Battery 2 Pack, 2000+ Cycles Lithium Iron Phosphate Rechargeable Battery for Small Solar, Camping, Lighting, Power Wheels, Fish Finder and More, Built-in 8A BMS - ULTRAPOWER 4-Amp 14.6 Volt LiFePO4 Battery Charger,12.8 Volt LiPO Lithium Battery Charger,Smart Battery Charger Maintainer for Cars,Motocycles,Golf Carts,UAV,Fishing Boat and Deep Cycle Batteries. - Nermak 2 Pack 12V 10Ah Lithium Ion LiFePO4 Deep Cycle Battery, 2000+ Cycles Rechargeable Battery for Solar/Wind Power, UPS, Scooters, Lighting, Power Wheels, Fish Finder Built-in 10A BMS --- ## 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.at/products/468443393-nermak-12v-7ah-7-2ah-lithium-lifepo4-battery-2-pack](https://www.desertcart.at/products/468443393-nermak-12v-7ah-7-2ah-lithium-lifepo4-battery-2-pack) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-07-22*
