FORTIVO 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 64oz

I'm sure this stuff works but my old marine battery was probably past reviving. The fact that I'm clueless where it comes to restoring old batteries didn't help either. Without even contacting them, they read my review and refunded my money. Not expected as the product didn't guarantee it would work for every battery. Standing behind your product is definitely a rarity these days. Again, this product probably works for most batteries. I just think mine was past reviving.

Didn't work for me maybe my battery was to far gone. Great people to deal with they refunded my money. I gave 5 star because they where so honest and easy to work with. Thanks

Does not work. I tried reviving a 6 V and a 12 V lead acid battery with this fluid. Both were fails, and actually seem to make the batteries worse. Also, they’re not very good instructions as to if this is just to top off acid, or if there’s only a certain amount you should pour in on top of real acid? Disappointing.

Item didn’t restore my battery performance. Easy to use. Could’ve been just a bad battery could work on another. Price was better than the local advance.

I'm sure this stuff works amazing when used properly. I use this on some extremely old lead acid batteries and it worked pretty well on a few of them but some of them were too far gone. Unless you have a way to restore the lead plates with this fluid You're not going to be able to restore more than 5-year-old batteries.
