Battery Tenders

[Ziggy]

I keep a tender on my RV batteries all the time. I take 'em home when not in use and keep both hooked up.
After 20+ years of just turning off, I just started the same "tendering" with my boat this year, experimenting with two different ones to see which I prefer.
Testing one of those $6 tenders and one of those solar 1.5amp battery mantainence panels, both from harbor frieght. See this Spring how they each performed.
