low cost battery reconditioner desulfator specifically designed for 12 volt batteries used in Motorhomes, Boats, cars and trucks. Suitable for batteries up to 250 Ah. Full 60 day

Hello Reader,I bought this unit, as I had a lead acid battery on a tractor that is not used too much, but failed to start after charging the battery. It was either this or a new battery & with the 60 day guarantee it is defiantly worth a try. I used the unit with a battery charger, over a 7 day period. For other reasons, I then left the battery in the tractor for a month, then tried it, it started first time. Therefore, unquestionably it had a positive affect, how long it lasts I do not know.After receiving the unit, I emailed their tech department with a couple of questions & within the day, got a very thorough response from someone who definitely knew their stuff.Update Oct 1 2015 - Battery has continually started the tractor without further offline charging. Definitely has had a positive & lasting effect.thank you, for your interest,Gerry (from Ireland).

Seems to do the job simply and well. Exactly what I needed and sits well with a large battery inside a large box. Comes with croc clips and post mounts. Haven't used crocs included as I attach to croc clips on either charger or electric motor when in use or charging using the post mounts (small ring connectors approx 10-12mm). Seems accurate so far and time will tell if it's doing it's job! This will get good use and I have high hopes. Came well packaged and was dispatched promptly with great communications and response to messages from seller. Highly recommended and will post review again if anything else relevant/of note!

Early days but it does appear to have improved the first battery significantly after 2 days of cycling charge/ discharge

I'll update when I get results.

Purchased based on promises in listing. Have previously made up the cheap £10 kits available on ebay. Result was that this item worked no better than the kit. Used on various sizes of 12V battery from high capacity halogen torch cells to alarm back-up batteries, all between 2-5 years old. It is virtually impossible to rejuvenate batteries which have been stored in a discharged condition for years due to chemical and physical changes that take place, so don't purchase this with the expectation you can do this, you would be better putting the money towards a new set of batteries and cycle them correctly to extend their life. Looking inside this item after it failed their are a number of very fragile components which would not cope well with extended periods of use / electrical load, but this is exactly what is needed / recommended to "revive" depleted cells in batteries. Overall very disappointed that product failed to perform or live more than a few weeks after the warranty expired. Save your money towards an earlier replacement of your battery, and recycle those old ones in the shed that you thought this product could bring back to life.

I was recommended to but another car battery. Would of cost me to replace the same type over a hundred quid. Seen this gadget on you tube. Thought I'd give it a go. So glad I did. After a week of normal driving. The battery is like new. Holds its charge. The great thing about this, it will keep the battery in tip top condition. Just connect it, cable tie it to the battery and that's it. Peace of mind that my car will start every time.

Yes I have use this unit on a battery the I would of had to replace. It has brought it back to full power. I have fitted them to three mobility scooters and my wheel chair now and I have seen a mart improvement.

I have used this item since august on a variety of different car batteries and done dozens of charges and discharges on each. It has not made any positive difference to any of them. The OK ones are still ok, the knackered ones are still knackered and most of the good ones are still as good (but no better) than they were before. One surprising result was that one of my good batteries is now knackered as the polarity of one of the cells is now reversed. I don't know whether this is coincidence or not but it had been fine before.My opinion is that this is a very expensive volt meter. As to the write up about needing to be metal to dissipate heat etc and that plastic cases couldn't do the same job, what utter tosh. The unit is always the same as the ambient temperature (which is probably because it isn't actually doing anything).I would have returned it but missed the deadline due to work commitments. Now I just chalk the loss up to experience.
