Review: It worked! - I saw a review of this and thought why not give it a try. First battery I tried it on was dead and would not take a charge. I kept going between charger and hooking this thing up for a few minutes and pretty soon the battery started to take more of a charge. Next thing I knew this thing had revived the battery. I have now used it on several car batteries that acted like they were going bad and it has them performing good enough that I can continue using them. All it had to do was save one battery and it paid for itself. Yes, I am pleased with this thing and its makes me sick to think of all the batteries that I have traded in that it probably would have revived.

You can read the voltage and it is limiting that it only works at 11 volts and above. I use it attached to the battery 24/7 so it desulfates with a charge. It has noticibly improved the capacity of the cells for more amperage. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vn/products/7827822-auto-pulse-400ah-lead-acid-battery-desulfator-revive-battery-regenerator](https://www.desertcart.vn/products/7827822-auto-pulse-400ah-lead-acid-battery-desulfator-revive-battery-regenerator) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-05-20*
