Rated 4 out of 5 by lovetowalmart70 Great Product
I bought it to maintain my car battery when I don't use it. So far all tests that I done to SBM confirmed that it delivers what promised. Under direct sun the output is over 20 volt and without sun just around 13 volt.

The Solar Battery Charger, keeps lawnmower battery topped off and easy to put slow charge on car battery.
Rated 5 out of 5 by mobear410 Super Excellent Product
If you have an older vehicle that the battery keeps dying on then this is just the product that you need or you can use it most anywhere that you can put it into the sunlight. Totally worth the money and the speed of delivery was great.

I bought two of these for two different cars that aren't driven much. The first one quit after 3 months and the other was dead right out of the box.
The specs say that the maximum operating environment temperature is 170 degrees F. I'm thinking it gets hotter than that on my car's dash. I wonder about the one that lasted just 3 months. Did it get too hot? If so, that's no so good for a SOLAR panel!
I'll add that this panel was always handled with care as I have a background as a technician in aviation instruments and sensitive medical equipment.
