FORTIVO [2 Pack] Battery Restorer and Desulfator for Lead Acid Battery - Prolong Life & Boost Charge Capacity, Battery Acid Refill and Additive for Golf Cart, RVs, Bikes, ATVs, Car Battery 32oz

I used this 2 Pack Battery Restorer and Desulfator on my car and RV lead-acid batteries, and the results were impressive. It noticeably improved the battery charge capacity and extended the battery life. The instructions were clear, and the application process was straightforward. I highly recommend this product for anyone looking to restore older batteries or prevent premature replacements. Great value for the price!

My 3 year old batteries would only give me about 4 miles on a “full charge.” But 2 months later I’m still getting about 12 miles per charge.I gave bumpy streets in my beach neighborhood which help shake the batteries as recommended by the supplier. I’ll probably convert to lithium next year.

Product did absolutely nothing may have actually made my battery worse

Fixed a battery that tested bad and wouldn’t hold a charge for a day. Saved me $228 bucks by restoring using this product.

I've had better luck with fresh acid in the past.

Works OK..it’s not a miracle cure. Takes some time and a good desulfator/ Charger.

I recently tested a concentrated battery additive on one of my golf cart batteries. The product claimed to break down sulfate buildup and restore capacity in lead-acid batteries. After adding the solution, I used a pulse charger for 5 cycles. While the battery now holds a charge similar to before, I'm disappointed that the specific gravity (SG) remains low, far from the ideal 1.280 for a fully charged battery. This suggests the additive may not be as effective as advertised in truly restoring battery performance. Despite its claims, I'm skeptical about its ability to significantly extend battery life or serve as a reliable alternative to replacement.

I’ve been using the battery desulfator for a week now, and here’s my experience.The packaging is straightforward and practical—two bottles of solution and a clear instruction manual. The instructions are simple and easy to follow, making the application process hassle-free. Even for someone like me, who isn’t very familiar with automotive mechanics, the product was easy to use.The most noticeable improvement is the car’s starting speed. Previously, my aging battery struggled during ignition, sometimes requiring multiple attempts. After using this additive, the ignition has become quick and smooth, almost as if the battery has regained its youthful energy.As for the claimed improvement in charge capacity, it’s harder to quantify. I haven’t noticed a significant difference so far.That said, this product isn’t a miracle cure. Battery aging is an irreversible process, and this additive acts more like a supplement that slows the decline rather than a magic elixir that restores peak performance. For severely sulfated batteries, the results might not be as pronounced. My car battery had been aging but wasn’t completely at the end of its life, so the effects were quite significant in my case.For users looking to extend the lifespan of their current battery and delay a replacement, this product is a solid choice. However, it’s important to manage expectations—it won’t resurrect a battery that’s on the brink of failure. I recommend using it while the battery still has some functional lifespan left to maximize its benefits.
