Correct and you know there is something to it when my local scrap yard gives me 5 bucks for a lead acid.
PS:Guys a millionaire,whats that tell ya?
O'Reilly Auto Parts out in Tillamook, Oregon gave me a $10 gift card last week. I used it to buy some wax for the car I pull behind the RV. Last summer did Yellowstone, Glacier and Yosemite Nat. Parks, this year the Oregon/Washington state and NP's.
I have several flexible solar panels for the RV. I only use them when I am going to be off grid for a few days. The flexible panels do not seem to hold up real well to long term UV exposure so mine will be essentially brand new for a long time as they are kept in storage (about 4 pounds for a 120 watt panel).
