Our 9 volt battery replacer / eliminator kit outputs 0.5 amps or 500ma which should cover any 9v battery powered device. **Q: A previous question was already answered about the power cord length. How long is the snap connector cord?** A: The length of the Eliminator Connector is approximately 6.25in **Q: will this work with "the basement watchdog model bwd-hwa 110 db battery operated water alarm"?** A: If it's a 9v battery powered device, and you can leave the battery compartment open, it should work fine. The eliminator can supply a lot more current, for longer, than a battery can. It's also always steady at 9v, at reasonable current draw. **Q: Why doesn't it work on my garage door opener?** A: Hello, we would be happy to help you figure out this issue, but we would need more details such as what was the normal power source for your garage door opener? Was it originally a 9v battery? When happens when you try to use the eliminator with it? Please contact us directly, and if possible send a picture of your setup and we will be more then happy to help you troubleshoot the issue more as out 9-volt battery eliminator should be able to replace 9v batteries in nearly all products that it is able to be connected to without issue.

So happy I bought this. ### ⭐⭐⭐⭐⭐ Great conversion for a 9v dc safe *by D***. on February 13, 2026* Works great. Helped me convert my 9v dc Gun Vault to ac. No more replacing batteries - or forgetting to replace batteries! ### ⭐⭐⭐⭐⭐ Works well-- correct DC polarity not an issue *by D***R on February 28, 2024* I've checked, and if the two-part plug-in substitute for a 9v battery is used as a kit there shouldn't be any polarity problem. The AC/DC converter plug prongs are reversible, because AC cycles back and forth, and for this purpose the converter doesn't care which prong the AC comes from. The DC polarity at the point of connection where the the adapter attaches instead of the 9V battery will always be right -- male pole positive. The seller explained to me that polarity can be wrong if an AC/DC adapter with a purposefully different DC polarity -- like for a guitar pedal -- is substituted for the converter that comes with the 2-part kit. ## Frequently Bought Together - 9v Battery Eliminator (9v DC Adapter & Battery Eliminator) - Replace Your 9-Volt Batteries with Wall Power Supply - THE BASEMENT WATCHDOG Model BWD-HWA 110 dB Battery Operated Water Alarm - Pinpoint® 9-Volt Battery Universal AC Adapter Kit 120VAC_AB --- ## 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.sn/products/82581378-9v-battery-eliminator-kit-500ma-ac-dc-adapter-connector-42in](https://www.desertcart.sn/products/82581378-9v-battery-eliminator-kit-500ma-ac-dc-adapter-connector-42in) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-08-28*
