XTREME CHARGE XC100-P - Charge 12V Battery Maintenance Charger Desulfator

Happy to have picked one up before they ran out of stock.

Okay. I was very skeptical. I had five different batteries that were no longer holding a charge whatsoever. All my other devices were saying the battery was bad. I plug this thing in, and let it charge for one week. And it brought the darn battery back to life. I was so excited I started plugging it into the lawn mower batteries, Motors motorcycle batteries, quad batteries ,anything that will take a charge. It brought back my marine battery.A motorcycle battery cost between 98 to $220. A car battery cost no less than a hundred bucks on up to 2 to three hundred bucks. Lawn mower batteries on another $75 plus. I had an old Yamaha battery that was on my quad. That was dead as a doornail. I put this thing on there for 5 days and it brought it back to life. All these years I've been wasting money just taking the batteries in after I try charging , and my machine say they're dead. Even the dealers in the stores say they're dead after they test it.This thing brought it back to life. You just hook up the positive and negative cable. And plug in the cord. It will automatically test your battery. Once it realizes that it can saved it it indicates 25%. I love getting up in the morning and walking on over see what percentage is on. After a day or two it'll be 50%, another day or two depending on the repair work that needs to be done. Going to hit 50-75% but once it hits 100 %,you're in business. Your going to be amazed. I got my lawn mower battery. Plugged it in and left it for a week and a half. Then I didn't start it for 2 weeks. Went outside and it crank right over. In the winter. It was better than a new battery. Sorry I can't stop talking about it .it's that great.Remember. Patience patience patience. Let it do its thing. Once it hits 100% you'll be very happy. also let me add. We have seven motorcycles. I'm always changing new batteries out every here. Battery tenders keep them charged but it still reducing the battery life. This thing brought back all those batteries and made them brand new as if they were just made. Can't believe all the money I lost for not having this years ago. I would have saved a bundle

I had a tractor that was cranking kind of slow, making it hard to start at temperatures under 20 degrees. The battery was over 5 years old, but still held a charge, it just didn't seem as 'strong' as it used to be. I tried a regular charger, which didn't help. Then I tried a trickle charger, which got it cranking faster for a day or two, then it went back to where it was. A friend suggested a desulfator, and based on reviews, I thought I'd try this one. Long story short, I hooked this to the battery for a while, and now my tractor cranks over better at zero degrees, than it did before at 20. It has been a month since I 'desulfated' the battery, and it still is working great, so I'm sure it actually did rejuvenate the battery, and not just 'charge' it. At close to $200 a pop, anything that gets me more use out of those big batteries can only be a good thing.Just a couple things to note, it takes time to work, so you have to leave it hooked onto the battery for quite some time. On my large tractor battery, I left it on for almost a week. However, the battery did not get hot, it didn't lose any water (or at least not enough to matter), and it did not overcharge. What it DID do, was bring back some of the cranking amps that seemed to disappear slowly over time, as the battery aged. The instructions clearly state that it will not repair a damaged battery, or one with an internal short, but I can vouch that it seems to add some useful life to a 'tired' battery. If it gets my tractor through the winter on the old battery, I figure it almost paid for itself, just in that one use.I have had similar results with other batteries I have tried it on. If the battery was fairly new, I couldn't tell it made a difference (I don't have a fancy battery tester, I just go by how fast things crank over) but I would say in most of the batteries I tried it on more than 2-3 years old, it improved the cranking power, sometimes by quite a bit. According to the manual, it is safe for all 12V lead acid batteries, including Marine and AGM types.

This is an OK charger if you want to charge your car battery SLOWLY and de-sulfate it as well. It charges at 2.5A, but states it is "Effectively 5A"? What does that mean? If it can only put out 2.5A, it can't be "effectively" anything higher!I watchedf videos and read web pages where people tested this little charger and revived COMPLETELY dead batteries. I had a couple dead batteries, I even added electrolyte and water, then charged for a week, didn't revive anything. I have never had this actually revive a battery yet. The picture shows a SLA battery I took out of my UPS, it charges fine. The other battery which was on top of this connected in series (which I took apart) I have been charging, it will charge for several hours then show it is a bad battery. I unplug it for a bit and charge again, same thing over and over and over. It has 12V, but the charger can't save it for some reason, says its bad.I use this charger on my Mustang because I don't drive it every day, and my Mustang model is known to have a battery drain issue with the Shaker 500 system. This is enough to keep it alive, so I use it for maintenance. A $70 battery maintainer. There are cheaper options for charging and de-sulfating, it is a good quality product from what I can tell, I just wish it was a little more powerful. Give it at least a minimum of 6A, that's kinda the standard for as CHARGER. 2.5A is more of a maintainer charge, if your battery is low it can take 2-3 days to charge with this. No kidding.
