PulseTechXC400 Xtreme Charge 4 AMP Smart Battery Charger Maintainer, Trickle Charger | Test, Charge, Condition and Maintain All Types of 12V Lead-Acid Batteries

I have been using this on a 9/17 Everstart battery for a couple years.Guess the fact the battery is 7 years old might indicate it does what it claims to do.Will see how much longer the battery will last but can say I got my money out of this battery.I also us it on a 2021 AGM battery. They often don't seem to last as long with just normal uses. Hope it helps with that battery also since they are lots of $$.

Works great. I had the 2 amp version for several years which worked fine. I bought this one because I figured it would charge a little faster if I needed to. Gave the old one to a friend who leaves it on his vacation car.

This trickle charger, restores, aged and old batteries to new condition. Removes the self fates in the battery and put it back into circulation. Excellent.

I only used it one time for charging and it did fine on a battery that was 50 percent charged. Got it to 100 percent in short order. I have not had a chance yet to use it to bring a really discharged battery back from the dead yet.

So far so good. Charged a couple batteries back up. Yet to see if they last or not.

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.

I'm using this on my 2019 EZGO Valor golf cart battery. I have only been using it for a couple of weeks seems to keep it charged. Wasn't having any problems with the battery before I started using the charger. Only time will tell but the technology seems sound.

Compact unit and comes with the different clips ! Only time will tell if it actually saves battery

Works as described
