SPARK Golf Cart Battery Restore Liquid Solution - Restore - Repair - 6, 8, 12 Volt Lead Acid Batteries - Made in USA - Expands Charge Capacity - Extends Battery Life - Non-Toxic - Larger 64oz Bottle

Was a bit skeptical but it actually worked, my golf card batteries wouldn’t charge (charger said the batteries were bad) I added this to the batteries as directed and a few days later they took a charge. Don’t know how long it will last but for now I don’t have to buy batteries. They are holding a charge like normal. Again it took several days to take affect. If your battery were ran dry this probably won’t work for you

give it some time, seems to help thats why 4 stars, maybe in more time. 5 stars

This really works! It saved us from buying 6 new batteries. It was easy to use and it came on time and was packaged well. Would use seller again.

Didn’t work for me, hopefully others have better success

Didn’t work

It’s a constant battle to keep good useable batteries installed in all of our vehicles and equipment. We also have off grid solar systems with lead acid batteries. So, needless to say if we can save an old battery or extend its life, then it’s worth it to try. I’ll outline what I did to an old (2012) 12 volt car battery. This battery showed 12.4 volts on my volt meter, but it wouldn’t turn over a small truck engine. After trying to start the truck, the voltage dropped to around 8.5 volts, and then slowly recovered. I started this experiment by emptying all of the electrolyte from the battery in to a clean oil pan, without stirring it up too much. Then I filled the battery with water and replaced the caps. I tipped the battery over on its side in all directions several times trying to stir up any debris in the bottom. Then, I drained the water in to another pan. This time it came out very dirty and reddish brown with a lot of sludge. I rinsed it again, until it drained clean. Then I refilled the cells about half full with the original electrolyte, and added 2 ounces of the “Spark battery restore liquid solution” to each cell. Then I filled the cells to the top level with the remaining electrolyte, and hooked up an old school type battery charger. I used the low amp, trickle charge setting and left it on overnight. In the morning the battery showed 12.89 volts. I decided to let it charge for a second night and the following morning it showed 13.34 volts. I re-installed the battery today and it started the engine very well. I have to say that I am impressed with the outcome, because replacing that battery right now would cost about $160, compared to the 12 ounces of restore liquid that I used. I am very happy with the results, even though I didn’t follow the directions on the label exactly, it worked, and I have enough to do 4 or 5 more batteries.

It was definitely worth a shot to see if my 6 year old near end of life batteries had anymore life left before spending a hefty amount.My batteries are 6 years old and if anyone forgot to place it back on the charger after use within 24 hours the batteries were spent.Well I'm glad to say this actually improved how long the batteries will stay charged if one of us forgets to place it back on the charger. Now can go roughly 48 hours without needing recharged.This takes a little patience It's not instant first you need to remove enough liquid to expose the lead fins and then top off with this Spark electrolytes. Drive or shake it around to get it to mix and then you won't see the full results for roughly a week.I don't know how much longer this will extend the life of my batteries but hopefully it's enough time for me to save up the money for that hefty bill.Hopefully my written and photo reviews are helpful, thank you!.

This is no miracle for really old dead batteries but if you batteries are several years old and not holding a charge for long, this will give you some additional charging capacity and help you get a little more life before you need to replace.
