Using charger to hopefully breath some life into some older batteries. So far it looks good. Made in China, and the leads are a little on the cheap side, but I believe the technology is solid.

I have a box trailer which I store my motorcycle. The trailer has 12v battery for interior lights. I recently had to move my trailer to a storage lot that has no 120v power available. This solar panel and QuadLink 4 Channel Charger Multiplier solution allows me to keep a maintainer and splitter for me to use on the trailer and motorcycle battery. I just installed this so I have no experience with the durability, but the solution is perfect for this application.
I had some questions about whether this product was what I needed after receiving the product. I emailed technical support and they called me on the phone to discuss. EXCELLENT customer support!

Works great! Worth the price!

14 days isn’t really enough time to know if a battery maintainer is doing a good job but they want a review. It seems to be well constructed. The installation guide was clear. Shipped quickly. I’m happy so far.

It works

How can a buy a new maintainer mine stopped working I've got the sp-7

SP-25 SolarPulse Charger/Maintainer (12V)

answered questions quickly and advise installed and waiting to see how they worl on rv.

Purchased 3 of these units to maintain batteries in my boat and Jeep at our seldom used desert home and happy to report that all batteries are fully charged even after sitting for 2 months. Extremely happy with the purchase.

This order was easy and painful. Fast shipping also! Thank you

I rent dump trailers and kept having customers complaining about the battery dying. Bought this kit about a month ago and I haven’t had a dead battery yet. Easy to set up and working as soon as the sun hits it. 100% recommend.

Xtreme Charge® XC400 4-Amp Battery Charger/Maintainer

Just placed a bulk fuel tank, with 12v system. Installed the solar on op of a dry box and ran wires inside. With drilling holes and placing the battery it took 45 minutes. Checked for a charge, primed the pump and we’re off to the races

Just installed, Will be used to keep my camper battery charged , I have a battery lock box for two batteries. I only use one. I installed the pulse on the inside with the battery solar panel on the outside. Very well-made product easy to install solar panel very well-made so far so good. I’m happy with my purchase.

I have had good success using the pulse tech charger. I use them to keep the batteries charged when they will be setting for along time.
