The solar panel arrived in good condition and worked just fine as soon as I connected the wires. I set it up on a work bench to test it out and it has worked very well. The rested battery had 12.46 volts showing and began to rise right away. I have not been able to do a sunny day test because it has been overcast and raining everyday. If there is decent light out the solar panel can do it's thing and that is just what I want. I will have to wait to give a better sunny day report, but for now all is well. Sorry for the lack of sunny day detail. I plan to use the charger on my travel trailer to keep the battery up. I did try plugging in a power inverter to see if it would work with one attached to the battery while charging and it worked as well.

Satisfied with the purchase.

Would I recommend it: yes

Con: the delivery time was a bit long I thought, compared to other purchases but Amazon has spoiled me with other quick deliveries.

Had a BatteryMinder on the garage roof since 2009 keeping the battery of my show car Mercedes 450SL charged. It's been perfect for the job. When I put it up, it seemed to me better to be raised off the roof an inch, so I glued 4 solid rubber bumpers at the corners. No rain build-up, no leaves, etc.

We had a huge wind through here in July, 2010, which broke out the top of a 40' willow 30 feet from the Battery Minder, which didn't move at all.

I never take it down. Rain or snow or heat, it keeps working fine.

Purchased solar charger for the RV batteries, 2 6V Trojan T-105s. Easy to install. Working as it is described. Hoping to keep batteries in charged state while the vehicle is sitting idle. It is giving me peace of mind that my $200+ batteries are not deteriorating as I write this.
