Our van has been in storage for the last two years. The invertor was accidentally left on and now the batteries have zero charge. I had the power connected all day, but no sign of any charging. Are they dead? Gel batteries about seven years old, hardly used. Collo.

The panel itself is 35mm thick and Ive placed it...

Hi, I have just purchased a Kings 120w Solar Blanket after reviewing the specs on the web site. However I was surprised to see in the user manual, when opening the blanket after purchase, that the solar blanket and MPPT regulator are not to be used to charge Lithium ion batteries. Stating that the MPPT c...
