I have had one for about 10 yrs & have loved it! I have been hard on it & I finally wore the power cord at the body so couldn't fix it. My bad so I gladly bought a new one. Timing was perfect for new model. 2-4-Way capable is great. M.

Been using your Power Pulse desulfators ever since I read about them back in early 90's,for someone who doesn't drive much,they give me assurance the car battery will still be good... like how the size has decreased as well.

SolarPulse® SP-12 12-Watt Solar Battery Charger & Maintainer

After the first use my battery was showing 100% charged. It was also reading about 13 volts. After sitting for 3 days it still showed almost 13 volts and 75% CHARGE. I am going to reconnect it and let it charge again for a few days to see what happens.

New Xtreme charger is working on my motorcycles and ATV. Thank you.
BUT, I dropped one of my 4 older units on the floor and it just blinks all lights now.
Thank you again.

The car/truck/UTV batteries test like new after several years of use. The cost savings resulting from long lasting FLA/SLA batteries far exceeds the cost of the PulseTech conditioners. I use battery test tools. I am impressed and I know my vehicles will start when I need them.

My jeep sits 9 months of the year in the garage. With the XC400, I don't have to worry about battery replacements when it’s time to ride.

This is my third Xtreme Charger & Maintainer and I consider them a “Must Have” for keeping my batteries charged up and ready to go. I live in a cold climate state and have three classic cars, a snow plow/ATV, a large mower and a tag-along mower. These systems ensure that my vehicles are ready when I need them and extend the service life of the batteries. I highly recommend them.

Don"t lose sleep wondering if your battery will crank your vehicle on a cold winter morning. Charge/maintain it withe the Pulsetech XC450

This is the second purchase of this item to go with my new PulseTech maintainer/ charger. It gives me the option of placing the unit inside my garage and leave my vehicle in the driveway. Great option for a great system.

Great product and high quality.

The XC400 appears to work as advertised. The AGM battery in my Chevy Trailblazer is approaching its 4th year in service and has been showing signs of getting weaker. A week or so ago when the weather was nice, I connected the XC400 to the battery in the vehicle and let it do its thing for three days. After the charging and de-sulfation should have been complete, the battery tested as healthy and the internal resistance was at 3.9 milli-ohms which I believe is a good value for an AGM car battery. My understanding is that it's the sulfation in the battery that causes the internal resistance to increase and that is what causes the batteries to fail. Perhaps Pulse Tech could provide more information regarding internal resistance values for batteries and the relationship to battery health. Having a basic value like Internal Resistance to test for when determining battery health would be helpful.

I like the feature having to select & start push buttons after I hook up the terminals instead of the charging beginning when circuit is completed. It does a wonderful job of restoring batteries. I put a higher amp charger on for the bigger storage batteries if this one does not get it restored & then switch back to the Xtreme to let it fully condition it.

Concept of the product is amazing and sounds wonderful! Time will tell if it actually produces the results, but my fingers are crossed

For many years, all my 12v lead-acid batteries receive the PulseTech treatment twice a year or more. the batteries last more than 5 years as a result. awesome gadget! thanks!
