12V solar battery tender，solar trickle charger，Solar Battery Charger and Maintainer， Suitable for Automotive, Motorcycle, Boat, Atv,Marine, RV, Snowmobile, etc. (1.8W Amorphous)

This was the 2nd time we ordered these since they worked so well. We needed them for more of our vehicles. Arrived quickly! Very satisfied with the product!

I bought several of these a couple years ago, through time I've needed to replace them, so I'd say the average lifecycle is about 2 years each. I use them on my ATV's, Motorcycles and camper battery to keep charged through the winter and they work perfectly. A couple items to note are:1. Having the alligator clip connected all the time to my camper battery caused it to corrode enough that the alligator clip was unusable after about 3 years.2. These do not connect to your typical tender connection whip that you might get from an auto store. You must use the ones that come with the panel.3. Besides the typical wear and tear these things keep my batteries charged and my toys ready for use, good value for the money.As mentioned I've bought these twice and didn't think twice.

This is my second one like the size and the low charge rate I use these strictly for maintance. The only reason I gave it 4 stars is because both units have a light (led) that does not work. I've checked and both are working, just the indicator light is INOP

unit looks to be well built. instructions are well written, positive wire is a white stripeon edge of a black wire ?{a blask and red wire would be a inpoevement. so at this point in new just out of box and manual read. once i install and watch it work for a while . ill add to my report.Well 6mos in only complaint i cant disconnect from battery from in side the car, wish the cord on the charger was only a foot long,

I bought two of these. I used them to keep a small 12v battery charged so I could run lights in my storage building. The first one lasted about 7 months before the led quit lighting up. When tested it was no longer putting out any voltage. I hooked up the 2nd panel and had the same results. It also lasted about 7 or 8 months.*** I took both panels apart and found that a solder connection on the back of the panel had come loose. It was a simple fix. I soldered the wire back then put a piece of electrical tape over the connection. Hopefully next time the panel gets hot and the solder gets soft the tape will hold the wire in place until it cools back down. Both panels are not working again. ***
