    The WORST thing for a battery is leave it dormant

    Posted by OGL on Jan 31st 2023

    I purchased the Renology solar charger/ maintainer over a cheaper brand because I have purchased their mono crystal panels 10 yrs ago and they are still operating. As for the Charger/ maintainer I put it a battery for 1 week and then switch it to another, it keeps batteries at about 12.38 volts which is fine One complaint people had was it wasnt water proof as you see in the picture i just put it in a large freezer bag. It may reduce the efficiency a bit but it still works Renology is the way to go for solar needs. This charger does as it should which make the battery active and fresh, it is NOT designed to max out a batteries voltage however it does as it is intended Keep a battery fresh and ready to go.. I use it on deep cycle batteries which are on my dump trailers and I use it on my lawn mower battery works on all applications..

    Nice unit

    I didn’t pay anything for it so it’s well worth having. I have it hooked up to my riding lawnmower. Keeps the battery full charged even all winter. Easy to connect and disconnect. It’s saved me one battery so far

    Used for my ATV, far away from an outlet. It works great! No more extension cords!
