I definitely wouldn't try switching them since it's a lithium ion battery - it could seriously overheat and cause a fire. **Q: Will this battery fit any battery holder available elsewhere? Can I possibly buy a battery holder that will fit this? Thanks!** A: not sure I drilled a hole in an old plastic file card holder and secure all wiring inside and feed the solar panel there also **Q: Is there a battery holder that fits this?** A: Hello, This pacakge including a 12V 5200mAh battery and a battery charger, there is no battery holder inside the pacakge. Thanks KBT Team **Q: If I was to cut the female end would the bare wires be capable of charging and dispersing power? Or does it need a separate input and output?** A: Hello, The female DC5521 plug is for charging only. The bare wires includes positive pole and negtive pole to provide electricity to device. If you cut the female plug and you need to charge the battery in 12V supply. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Upgraded my wife’s breast pump to be portable! *by on Reviewed in the United States May 20, 2025* This was the perfect thing to turn my wife’s spectra S1 breast pump into basically a portable unit. Apparently this battery is so strong it lasts twice as long and doesn’t lose its power compared to the much more expensive portable version( the S2) ### ⭐⭐⭐⭐⭐ Nice *by on Reviewed in the United States February 14, 2024* Nice battery. As others have said, no relevant instructions on charger, but research elsewhere suggested, and experience now confirms, that it's basically plug into power outlet, connect battery and wait until led on charger changes from red to green to show full charge. Battery life and longevity as yet unconfirmed. ### ⭐⭐⭐⭐ Nice battery and charger pack *by on Reviewed in the United States January 8, 2025* Battery looks well made and is working well. I like the connector arrangement. The charger is a little anemic. Takes longer than I would want. It does work fine though. ## Frequently Bought Together - KBT 12V 5200mAh Rechargeable Li-ion Battery, DC5521 Male Connector, Replacement Battery Pack with 12V Charger Compatible for 12V Device 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.in/products/538356120-12v-5-2ah-dc5521-connector](https://www.desertcart.in/products/538356120-12v-5-2ah-dc5521-connector) --- *Product available on Desertcart India* *Store origin: IN* *Last updated: 2026-07-09*
