In the post about my 18 yr old batteries in one of my Diesel Trucks that was kept on a small “Battery Tender” trickle charger. There were some comments about the Harbor Freight Solar Battery Chargers, did some research as I want a couple Solar Chargers and found that the Harbor Freight ones DO NOT come with a Charge Controller in them, those are sold separately. So beware that those chargers will burn up batteries. They will not stop the charge current at all.
I run a few Solar Gate Openers and had to replace a Panel today on one of them. Went to Harbor Freight and found a Charge Controller for a 7watt Solar Panel,I already have. While there I thought I would check out those small Battery Solar Chargers, and in doing so found that in the instructions it notes to not use them without a controller sold separately.
I’d hate to see batteries ruined.
I think I am going with a couple of these below. Comes with a controler.
