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

Have purchased several of these, they work well to keep batteries charged and to extend their life. Very good product and versatile. Each of my 12V automotive batteries has a PulseTech product attached as does my Ryobi 48V riding mower.

I have been using one of these same type chargers on my 2011 Chevy diesel truck and it works great. Extended the life of my battery well over a year. Finally bought one for my Harley since I don’t ride as much as I used to. I would definitely recommend this charger to anyone.

Holy crap!!! It actually works!!!!

4 stars for its efficiency and will absolutely take a battery to 100% charged, lots of charger don’t. They shut off when they think the batteries charged but often are only charged to 80-90%. Pulsetech drives them home. This charger will restart if there’s a power outage, making it ideal for a storage vehicle. The xc450 does not! I’d have given 5 stars if it had temperature compensation, but for some reason Pulsetech doesn’t do this? TBD if this will be an issue in extreme hot and cold. I’m not sure if I’d leave this hooked up for a week during the summer without temp compensation. You may dry out the battery as this floats/maintains @13.9 which would be a little high for a flooded battery in the heat.

Works great

I think the pulseTech save my battery's life.

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.

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.
