I have replaced the batteries in a 90's fold n go power scooter with these amazing little gems. Can and does still use its original charger, battery pack is now half the weight of what it used to be, and packs quite the punch. Installed very easily by swapping everything over to the new batteries, fully charged in very little time and scooter that had been sitting for years was back on the road. Review: Seems to work OK with Cyberpower UPS - I purchased two 10 AH 12 V batteries and received them today (6-30-26). I installed them in my Cyberpower CP1500PFCLCD UPS as a test to see if they would both fit and power the unit. The fit test worked great. I was concerned that the dimensions listed for these LiFePO4 batteries were slightly larger than those listed for the OEM batteries. I tested functionality both plugged in and unplugged with the UPS powered on and everything seemed to work as it should. I then connected the UPS with my electronics and turned it on (connected to the AC power) and everything is working OK so far. At present, I see no reason why Cyberpower ups owners shouldn't use this battery substitute instead of the OEM lead-Acid version but I will update this review in the future if I encounter any issues with these batteries. Afterthought: While the mfgr doesn't recommend this battery solution for UPS above 1000 VA, I felt confident using it in a 1500 VA unit because my electrical loads are very light compared to the UPS rating AND I have whole home electrical backup so the UPS would not have to carry the load using the batteries for more than 2 seconds when an outage occurs. I don't know if I could honestly recommend this solution for someone who relies solely on the UPS for backup during a long outage with over 1000 watts of load connected. Be sure that you will only expect light loads during any outage if you decide to install these batteries in your UPS. For those wondering why I even use a UPS with whole home backup: The delay to switch to the home backup can take as long as 2 seconds to kick in when a grid outage occurs. The ups switches much faster (~ 20 ms) and keeps my electronics powered during that short delay. ## Features - 【Superior Performance】: Lithium iron phosphate battery has high energy density, Long cycle life, Good safety performance, No memory effect, etc. NERMAK LiFePO4 battery has built-in BMS protection to prevent overcharge, Over-discharge, Over-current and short circuit, and excessive low self-discharge rate ensuring up to 1-year maintenance-free storage. - 【Long Cycle Times】: Lithium batteries 2000 + cycles no problem while the traditional lead-acid batteries only 200-300 cycles, More safety and environmentally friendly than lead-acid batteries. - 【Widely Uses】: Widely uses in most areas such as: Lighting (LED strip etc), Scooters, 12V router, RV/outdoor camping, Power wheels, Fish finder, Backup power, Ham Radio, Cellular remote camera, Solar/Wind power and more... - 【Expansion and Recharge】Can be connected in series or parallel, in series, Up to 4 identical batteries can be connected，Quick charge by 5A , and heavy-duty output discharge up to 10A continuous and 2C Pulse. - 【Warm Note】: 2*12 Volt Replacement lithium ion battery，12 months warranty, If you have any question for our product, Contact us: click the "Ask a question" on our storefront or in "YOUR ORDER" options click the "contact seller" (please use LiFePo4 special charger, with fully automatic SLA charger may not be fully charged) ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09H3FG1D5 | | Battery Capacity | 10 amp_hours | | Battery Cell Composition | Lithium-Phosphate | | Battery Type | Lithium-Phosphate | | Best Sellers Rank | #12,990 in Health & Household ( See Top 100 in Health & Household ) #13 in 12V Batteries | | Brand | NERMAK | | Brand Name | NERMAK | | Compatible with Vehicle Type | Fish finder,12V router,Lighting,Small UPS,Ride on toys | | Customer Reviews | 4.2 out of 5 stars 1,077 Reviews | | Included Components | 2*12.8V 10Ah LiFePO4 Battery | | Item Dimensions D x W x H | 5.94"D x 2.56"W x 3.91"H | | Item Weight | 1.2 kg | | Manufacturer | Huizhou Yu'an Technology Co., Ltd. | | Manufacturer Part Number | 12V 10Ah-2PACK | | Manufacturer Warranty Description | 1 year | | Model Number | 12V10A | | Number Of Cells | 2 | | Product Dimensions | 5.94"D x 2.56"W x 3.91"H | | Terminal | F2 Terminal | | Unit Count | 2 Count | | Vehicle Service Type | Fish finder,12V router,Lighting,Small UPS,Ride on toys | | Voltage | 12.8 volts | ## Product Details - **Battery Capacity:** 10 amp_hours - **Battery Cell Composition:** Lithium-Phosphate - **Brand:** NERMAK - **Item Weight:** 1.2 kg - **Number Of Cells:** 2 - **Product Dimensions:** 5.94"D x 2.56"W x 3.91"H - **Terminal:** F2 Terminal - **Unit Count:** 2 Count - **Vehicle Service Type:** Fish finder,12V router,Lighting,Small UPS,Ride on toys - **Voltage:** 12.8 volts ## Images ![Nermak 2 Pack 12V 10Ah Lithium Ion LiFePO4 Deep Cycle Battery, 2000+ Cycles Rechargeable Battery for Solar/Wind Power, Scooters, Lighting, Power Wheels, Fish Finder Built-in 10A BMS - Image 1](https://m.media-amazon.com/images/I/61B69x6e+6L.jpg) ## Available Options This product comes in different **Style** options. ## Questions & Answers **Q: With two of these hooked together can it be charged with 24 volt charger? yes or no.** A: Yes,It is possible to charge two 12v batteries connected in series with a 24V charger, our Lithium ion battery has a voltage of 12.8V, you may have to use a 25.6V Lifepo4 charger to fill the battery, if your charger is 24V, one of the batteries will be undercharged, causing an imbalance in battery charging, I hope my answer can help you! **Q: What is recommended max charge current?** A: LiFePO4 should be charged or discharged under 0.5C (0.2C preferred). For a 10Ah version with 128Wh. You should charge it no more than 3A (preferably 2-3A). **Q: Will this work with a trolling motor and for how long will it run ?** A: Thank you for your question, our batteries can be used in a trolling motor, but I don't know how powerful your trolling motor is, so I don't know how long it will run, our batteries are 128Wh, if your trolling motor is 100W, it will last for more than 1 hour, I hope my answer can help you. **Q: Got a shoprider Jimmy electric chair, will these discharge to the extent that you cannot recharge them like the lead acid batteries that come with it?** A: All batteries will do that eventually. The advantages of these are they will tolerate 80% discharge per cycle before any degradation (as opposed to 50% for lead-acid). and they offer many times the cycles. I can’t speak to their suitability for your application, though. They’re only 10AH each. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great cost for an effective replacement. *by D***S on August 14, 2025* Although slightly shorter in height than original batteries, work like a charm.

One battery seems to have died and will not take a charge. Apparently the return window is up and I can't get support. Would not recommend simply because one of the batteries have already died. I purchased in February 2026. Nermak reached out and refunded me the amount for the battery. Customer service team stepped up where the battery failed and made things right. This shows they stand behind their products and understand sometimes things happen. I appreciate the assistance and have adjusted my review rating due to exceptional communication and customer service. ## Frequently Bought Together - 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 - ULTRAPOWER 4-Amp 14.6 Volt LiFePO4 Battery Charger,12.8 Volt LiPO Lithium Battery Charger,Smart Charger Maintainer for Cars,Motocycles,Golf Carts,UAV,Fishing Boat and Deep Cycle Batteries. --- ## 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.sk/products/389334670-nermak-2-pack-12v-10ah-lithium-ion-lifepo4-deep-cycle](https://www.desertcart.sk/products/389334670-nermak-2-pack-12v-10ah-lithium-ion-lifepo4-deep-cycle) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-07-28*
