Q&A

1.Do I need to make some preparations before desulfating?
- Check the battery voltage. The voltage should be more than 11.5V, or the desulfator cannot enter into the working cycle.

2. How to use this battery desulfator?
- Connect the desulfator to your battery (leave it with battery charged or not), then it displays battery voltage and automatically selects 12, 24, 36 or 48 volts.

3.What is the button used for?
- When the desulfator shows Cxx, you may select the voltage type by yourself with it.
- When the desulfator works, you may press the button to stop.

4. What are the targeted battery types and situations?
- Storage battery, winter maintance
- 3 years old battery or younger
- 12V 24V 36V 48V battery bank

5. Can it be used in lithium batteries?
No. It only can be used in lead acid batteries. Also, it will not work for damaged or dead battery.

6. How can I feel the improvement?
You can record the discharging time of your battery before and after you desulfate the battery.

Working Cycle:
1.After you finish the battery charging process,connect the battery to the battery desulfator.
2.Firstly,the battery desulfator will show the battery voltage.
3.Then it automatically selects 12,24,36 or 48 volts.C12 means 12V battery bank,C24 means 24V battery bank,C36 means 36V battery bank,C48 means 48V battery bank.
4.Red light will flash in cycle when it desulfate the battery.

Customers are mixed about the ease of use of the battery charger. Some mention that it's easy to use with no hassle or fuss, while others say that there are no instructions or manual.

"Couldn't be easier to use. Just remember that it runs on the battery's own power, so disconnect the charger...." Read more

Customers are mixed about the voltage of the battery charger. Some mention that it can do many different voltages, and is good for checking voltage. However, others say that it would not detect the proper voltage and even reads negative.

"...improvement in terms of CCA, internal resistance and Load Test voltage readings - the battery has been restored to around 90-95%...." Read more

"The first device was dead on arrival. It would not detect the proper voltage. Amazon promptly sent a replacement and it appears to be working fine...." Read more

Customers are dissatisfied with the charging speed of the battery charger. They mention that it takes a long time to charge bigger batteries, and it does nothing to improve charging performance.

"...If I left the ignition on for more than a few minutes. It would slow crank. If I didn't drive it long enough to recharge the battery it would die...." Read more

"...It WAS NOT working well, simply put, it would charge quickly, say it had 'regular' voltage, then deplete much faster than 95aH capacity...." Read more

Surprising results. Looks promising.

Surprising results. Looks promising.
UPDATE 7/15/2018:It took a while for me to get an opportunity to use this device in a real world test. I am completely surprised and shocked at the improvement this device made on several batteries. Initially, I used this on several small 12v batteries made for scooters. They seem to be better, but I just didn't know how much, or whether it was from using this device or just general charging. Now, I have a 12v AGM jetski battery that was holding around 5.6 volts consistently. It would charge to around 11.9 volts, but would drop to 5.6 volts after a day of sitting there undisturbed and not connected to anything. I decided to charge the battery to 11.9v and quickly attach this device to let it do its magic. After it stopped running, I charged the battery again, and this time the battery seems to hold charge around 10.x volts. Wow! I'm amazed at what it did in the first run. I ran it through a few more charge and desulfate cycles, and have decided to let it sit for a week to see if it will keep its charge. Will report back soon. This device did not come with any documentation on how to use it and what to expect, so I'm dinging it 1 star. It appears this $20 desulfator device actually saved my 12v AGM battery, while the other $50 charger/desulfator combo device I bought ruined my deep cycle 12v battery (*not; see 8/6/18 update; desulfating can drop electrolyte levels and needs to be replenished). My next test will be to see if this device can fix the deep cycle battery ruined (*not) by the $50 charger/desulfator combo device.UPDATE 7/31/18:I found that the first time I used this on the AGM battery, the battery seems to work better (maybe a lot better). After a few cycles of charging and desulfating, I found the battery condition worsens and now not retaining its charge as well as the first few times of desulfating. My recommendation is to use it only once or twice on a battery, as there appears to be a declining benefit and possibly a negative affect after repeated uses on the same battery. I will do more testing and report back.UPDATE 8/7/18:After more testing, I discovered something that is not mentioned in the non-existent user manual. In the process of desulfating, this device may cause some of the battery solution/electrolyte/sulfuric acid) to evaporate. Adding water to replenish the electrolyte appears to remedy the problem of battery charge retention. So be sure to add water if the battery's cells look dry or low (see provided photos). Be careful doing so, because sulfuric acid is very caustic and getting any splatter on your body or in your eyes has damaging consequences. I read that AGM batteries have a catalyst plug to convert evaporating gases back to liquid; although I believe that system did not work on my AGM battery. In conclusion, this desulfating device and the other $50 desulfating charger appear to both do their job, with some intervention required when battery solution/electrolyte is lost in the process.ORIGINAL POST:I wish I could say something great about this product or something bad. Unfortunately, the way this products is designed, it is hard to tell whether this device actually works or not. In practice, it takes a long time to realize whether the technical marvel of desulfation technology is having an impact or not. Something is happening and energy is being consumed in the process, but does it prolong battery life?---We probably won't know any time soon. I thought this device would charge the battery while it is desulfating the battery or immediately afterwards (automatically), but it only desulfates---so the battery must be recharged multiple times in order to achieve the desired effect. I do like that it can do 1-4 batteries connected in series. Honestly, I'd rather get a device that does it all (and no manual intervention; i.e., where I don't have to manually charge, desulfate, repeat). So, I am ordering another item from Amazon that promises to do exactly that...
