It fit perfectly, same dimensions as those old batteries but is much lighter and with more capacity. The built in BMS allows us to continue using the original charger that came with the lantern. We have tested the unit and while we have not run it down, it is clear that it will run a fair amount longer than the old gel cell could do. ## Features - 【High Safety Performance】Safety is the top priority when we are building batteries.

It fit perfectly, same dimensions as those old batteries but is much lighter and with more capacity. The built in BMS allows us to continue using the original charger that came with the lantern. We have tested the unit and while we have not run it down, it is clear that it will run a fair amount longer than the old gel cell could do. ### ⭐⭐⭐⭐ I only use this as a "temp" 12V "power source" projects around the house that need 12v power. *by S***N on February 27, 2025* I DO NOT use this as a constant source of 12v power for anything, so I CANNOT attest to the "longevity" of this battery or the overall "life" of the battery for daily use. I got this primarily to "open" fuel injectors to clean them out without using my car battery and other small projects around the house I need a "temporary" 12v power source for. (I like that it is very SMALL and LIGHT (for a 12v power source!) so I can just put it on a shelf in my garage until the next time I need it!) It worked well to open my fuel injectors so I could a clogged one and then stored the battery. I have a "charger/tester" that FITS this battery and after using this for that ONE project I have not needed to use the battery since. However, I DID hook up the battery to the "tester" and it still showed "full power" several weeks later for what that is worth. Considering that I do not use this for a constant power source or in a "daily use" item, I cannot attest to the longevity or the "starting power" of this battery for use in that manner. However, for the purpose that I USE IT FOR, an easily stored 12v battery source it has worked well for me for that purpose. At the time of review, it is currently "on sale" for under $30 which is definitely on the "low end" for a small compact Li FePO4 battery. IT has worked for me as a "handy" 12v project power source for "projects", I however cannot attest to its durability or longevity for "constant use" due to the way I used and use this product. --- ## 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.us/products/676936738-12v-10ah-lithium-li-fepo4-b-attery-with-built-in](https://www.desertcart.us/products/676936738-12v-10ah-lithium-li-fepo4-b-attery-with-built-in) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-25*
