Best 12V feeder batttery charger?

'Need a charger to leave at the lease. We're currently running 13 feeders. Any recommendations?

Has to be idiot proof, can't overcharge, etc.

Thanks for the help.

Go by Mummes on 281 north and see what they have. Used to have a low milli-amp charger that had cutoff/float when it reached full. Also was a dual multivolt charger for 6 or 12 volt. They were cheap back years ago when I bought one. I would think the big feed store before Boerne on IH-10 would have them in stock also.

18 Volt 5 watt solar panel is what I have running on my hog light. Been over a year and its doing very well.

Get one of these, around $20 at Walmart, wont over charge, does 6 and 12 volt all you do is hook it up and plug it in it tells you if battery is good or not and automatically senses weather it is 6 or 12 volt no adjustment needed. Works great on deer feeder batteries.

I have had one for years. Am currently on my second one because I left the 1st out in the rain charging boat batteries while on vacation.
