Review: I’m sorry, but I LOVE this battery… - I’m sorry, but I love this battery. Charges pretty quickly, but lasts a long time, a little “pricy” for my model building budget. I originally bought this battery to power the Arduino in my (self printed) 1/1000 Crossfield Class Federation Starship. But I liked playing with it so much I have yet to close up my U.S.S. Discovery. Our neighborhoods power went out for three days. I took this battery, about 100 leds and lit up our (above averaged sized) front room. We had three nights with the kids and my mother-in-law playing games, doing puzzles or even just talking. I still wish I had a generator though, so don’t go thinking you can power your refrigerator with this. But if you are thinking that chances are you can’t read anyway so… ## Features - Package includes: 1*12V 1200mAh battery pack, 1*12V battery charger. - Battery size: 70*55*20mm (L*W*T),Battery weight about 132g, battery cable length 18cm, 12V charger cable length 90cm. - Premium battery pack: Build in protection board, prevent battery from over-charge, over-discharge, over-voltage and short-circuit.

Maybe perfect for something really low draw although I'm not sure what that would be. ## Frequently Bought Together - KBT 12V 1200mAh Rechargeable Li-ion Battery, 12 Volt DC5521 Male Connector, Replacement Battery Pack with Charger Compatible for 12V Devices RC Car, Boat, Robot, DIY, LED Light Strip, CCTV Camera - (Real 18AWG) 10 Pairs 12V 5A DC Power Pigtail Barrel Plug Connector Cable, 2.1mm x 5.5mm Male Female DC Pigtail Connectors for CCTV Security Camera and 12V Power Supply Adapter by MILAPEAK - LUORNG 5Pcs 10A DC-099 Power Jack Cord Socket Threaded Female Mount Connector Adapter with Pre-soldered Wires and Waterproof Cover Cap, 5.5 x 2.1 MM --- ## 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.tn/products/537481198-kbt-12v-1200mah-rechargeable-li-ion-battery-12-volt-dc5521](https://www.desertcart.tn/products/537481198-kbt-12v-1200mah-rechargeable-li-ion-battery-12-volt-dc5521) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-21*
