    Battery still good after 5+ years storage, but solar panel is toast!

    Battery still good after 5+ years storage, but solar panel is toast!
    Planning to leave the country for two years, I put my truck in storage in summer 2018, sitting outdoors in Texas, no sun shade. I had just bought a brand new battery for the truck and thought it would be a shame to let the $90 battery die while sitting there. After reading a lot of reviews of inexpensive solar battery tenders, I bought this, feeling no confidence it would work, much less even survive. I disconnected the battery from the vehicle, connected this tender, and left.When I came back, life happened, and I didn't get my truck back until late 2023, when I towed it to the driveway to sit until now, Feb. 2024.I just assumed the battery was dead after five years, tender or not, and was already removing the bracket to trade it in on a new one, but I thought, why not just test it? The multimeter said 12V, but I still didn't quite believe, so I connected the battery back up to the truck. I couldn't believe it actually cranked over, and very strong, too!However, the battery tender's plastic cover melted under the Texas sun. I don't think that's the tender's fault, though: you can see the cracks in the truck's dash that weren't there before.So it's liking like this turned out to be a good bet: $30 to save a $90 battery.
