My car battery was dead for a year. So dead the locks were not even working. I tried to just charge the battery and still could not get the car to start. I added distilled water And brought the levels up on the electrolyte and still no cranking amps. I added this amazing product and charged the battery and to my happy surprise it worked. I have not had a charger on it in over 4 months and even on cold days after sitting for a week it will still start up. This stuff is awesome! Saved me from having to purchase a 180 dollar battery for now.

It was worth a try, but did not work. Wound up replacing the batteries. Lot of money.

I recently found an old Hercules generator that was sitting in a barn since 1978 along with 12x very old batteries that weight 170lb each, batteries were 100% dry so I filled them with distilled water and placed them on charge for weeks, still they were not holding a charge so I sent 6 of them to recycle and kept the other 6 connected to my 24 volts solar charge controller, meanwhile I started doing research on something that could recondition them, after reading several good reviews on this product on Amazon I bought two bottles and added some to these large batteries, I still couldn't get them to work so I left them alone on the solar charger till I will find time to send them to recycle, probably about 3 months later I was working in my garage at night and just checked the charge controller which usually shows charge level as 12-20%, this time it was showing 70% so I went ahead and connected my 100W power inverter just to try to see if these batteries can run any tool, my angle grinder worked perfectly fine while the batteries maintained the 70% charge, the next day again I used my grinder, and chop saw on the inverter for about 30 minutes, this time the sun was out so the charge controller was working hard to charge the batteries while the inverter was drawing currents, the same evening when I checked the battery level it was sitting at 81%, that is too good for a battery that was sitting in a barn for 41 years. As of now my batteries are sitting at 94% but I did not use them since last time, it looks like the more they are used the better they get so I will try to hook the inverter to a high current tool and see what happens. I regret that I got rid of 6 of these batteries, they are 6 volts 400 Amp Hour batteries, this product seems has made a miracle, I just placed an order for 3 more to add them to my weak golf cart batteries.

Hi. I am running two 48-volt and one 12-volt bank of Trojan L16E batteries on a fully solar house. The 12-volt group was going bad. That's two 6-volt batteries in series. One of the batteries n the 12-volt group was a consistent about 4-volts after discharge overnight and the other would drop to just under 6-volts. Both batteries showed low electrolyte quality on a hydrometer with the worst battery showing one bad cell. I picked up a bottle of this to try and got it all installed. Its best to do if the batteries are low. I had to remove the 2 ounces of electrolyte from each cell. no big deal. I replaced those 2 ounces with the battery additive as directed. After two days of normal use and recharging the lower battery dropped to 2-volts on discharge while the other battery lost about 1-volt under its last discharge rate. This was due to the other battery dragging it down I figured. I took one of the older batteries out of one of the 48-volt banks and replaced to bad battery in the 12-volt bank. The 12-volt bank began to work perfectly with only normal drop during discharge. I had to replace the bad battery with a new one. I don't know if the fluid helped the one good battery in the 12-volt bank but the electrolyte in the battery does show an improvement. This could be from it getting a better charge and discharging less at night. So moral of the story is, I don't know if it helped or not. I do know that the bad battery got worse after its use. I have other batteries that may benefit from the fluid that are showing that the electrolyte is getting weak. So, I might try again on those batteries. It's just something to consider.

Terry, I just wanted to say thank you for your product and referring your friend Steve. My battery had a reading of .9v out of 48v And a diagnosis of the "battery is junk and not worth trying to restore" from large battery company. It cost me almost $300 for that diagnosis by the way.. I had a volt meter reading of 44v after the first treatment and charge. Thank you so much. You make a incredible product and it was nice to speak to a company and actually feel helped when done. Today it is so rare to even speak to a live person much less have the person talk thru the issue and the solution instead of telling you they cant help or pass the issue to some one else that does the same. Thank again Sincerely Ken "Thermoil for Life"
