Q: Does this have a blocking diode?

It is listed in product description has having a blocking diode.

Q: how long will it take with good sunlight to recharge a dead 12v automotive battery?

This highly depends on your definition of "dead" as well as "good sunlight". However, I'll give you an example of my experience with a 10w solar charger on a very low battery in the south. I maintain a church truck that gets started only on Sunday and it doesn't drive long enough for the alternator to do anything, plus I don't think the alternator even works so every start drains the battery quite a bit. Within about 2-3 months the battery can go from fully charged to not able to start the truck before I installed a solar panel. Once Covid hit I charged the battery for the final time with a battery charger to get it brought up high enough to start the truck again, but it was still starting very slowly because I couldn't leave it on overnight. I bought a 10w solar panel and attached magnets on the back then stuck it to the hood and plugged it straight into the battery. Now it starts with full battery voltage every Sunday, and even recharges the battery from the starter drain and no alternator recharging. It gets about 10 hours of sunlight every day and it's sitting flat on the hood which gets the best use of the noon sun which I think is the strongest. Sorry for the super long answer, but with solar there are no real constants and everything is very subjective to your location and even the angle of the panel.

Q: Are there any directions with this item? also, do i peel off the plastic coating? it is all bubbly like i should, but i am not sure.

Yes, peel of the thin plastic. If you need instructions there are 2 different PDF files available in the product information section of this item.

Q: “Will this charge two deep cycle battles at the same time?

10 watts at 12v DC is only .83 amps at peak most deep cycles are 80-120 amp hour battery’s so your talking 200-300 hours of peak

4.2/5
