PulseTech XC400 Xtreme Charge 4 AMP Smart Battery Charger Maintainer, Trickle Charger | Test, Charge, Condition and Maintain All Types of 12V Lead-Acid Batteries

Bought this because of their pulse technology - supposedly patented - that is supposed to extend the life of your battery by desulphating plates in your battery. I don't have a battery tester, so I can't say if it works or not, but there were enough credible reviews to give me hope. Here is what I do know. The desulphation mode runs automatically and constantly while hooked up to a battery. It runs a test every so often while it is charging the battery, shows you what percentage of charge the battery has, and adjusts the charging rate accordingly. Once it reaches full charge, it will automatically drop into trickle charge mode - but continue the desulphating routine. If the plates gain "new" ability to hold more charge due to having sulphates removed, it will go back into charge mode until it reaches 100 % again, and then drop back into trickle charge mode. I have witnessed this multiple times on the older battery I have in my truck, so I am hopeful that it is indeed cleaning the plates and will make my battery last longer than their usually short life span. Because it constantly works to clean the plates, I have started hooking it up to my truck overnight on the weekends, just to give it a chance to keep the battery plates clean. I have also used this charger on my motorcycle battery as a trickle charger between rides, and it has worked for that also. This is now the only charger I use ( I have others ) and if it does indeed extend my battery life, I will not bother using any other.

Already fixed my atv battery that sat dead for a year!

Units are simple to use. I have been using PulseTech products for over 15 years now and I have seen a improvement in the batteries life span. It is a little on the more expensive end for a battery charger but I can see a long term payback on not having to replace batteries as much. Plus the system does everything just plug it in and connect it to the battery.

It is not like the older de-sufator ,, even on the back specs. the older unit had different ranges and pulsers. Believe me the old unit brought back dead batteries , except the ones which probably had plates touching

These are great chargers I have 3 of them working great!

Great Quality product works Great would buy again and again. Has saved so many batteries.

Works as advertised, shipped fast, sustaining charge just fine.

I bought this charger in July & it started indicating bad battery after 7 months. The battery is new & upon connecting to another charger, it charged correctly. This charger was on an inclosed generator and never got wet or any other damage. It performed good for several months then kept defaulting to bad battery. After unplugging and reconnecting, it worked for several days then shut back down. Found out during power outage the battery was dead. Charger did not function properly.

I had an old AC Delco charger that delivered a pulse charge and it restored quite a few batteries. When it gave up in a puff of smoke after 30 years I needed a replacement. I've tried a couple of chargers that claim to start with a desulfication cycle but it's a one time burst that does nothing. It can take days or weeks to properly restore a badly sulfated battery and that's what this unit does, I'm very happy with it and I'd recommend.

Works as described
