Would this be able to charge an 85 AH 12V deep cycle battery at say 60% within one day in average to ideal conditions?

I would ask Renogy: Their customer service rocks. I called and hung up after no one answered. I still received a call back the same day. 909.517.3598 or info@renogy.com -I have not wired a battery charge indicator to my system, so I can't help you that way. Good Luck!

Remember that you are pushing amps back into the battery, and with normal losses this 5.3A panel and charger will likely give you 4.5 amps per hour at the battery in good to excellent lighting conditions (that's what I'm getting here in central Indiana). In a day, consider that you'll have 6 hours of bright sunlight, and another 4-6 of indirect sunlight. Conservatively that's about 8 hours of (8 hours x 5 amps) or 36 to 40 Amp-hours restored. That's enough to restore your 85 Ah battery each day if you take it down to 60%. This system should be fine for your battery--and others might point out I'm being very conservative. Even in late afternoon in indirect light I'm getting 4+ amps. You may find a fully-recharged battery each day by mid-afternoon.

Yes. I have this mounted on my boat dock to charge a 12 v Battery for my boat lift. Working perfectly.

i am not sure. but i have a 1.5 20 amp charger on a timer for one hour every day

Yes, I hooked a 5w trickle charger panel to a 12v battery and it worked well. Might want to go with a 15w panel however- mine loses charge if I leave it on 24/7.

Definitely. I'm not positive what the lower limit of the charger is, but I live near Edmonton, Alberta Canada, and I use mine to keep my trolling battery and main battery charged during the year when not in use - and also through the winter. My boat is stored in a non-heated seacontainer in my yard, and temperatures drop to -40 C here (-40 F).

Probably not. Your battery pack is giving you 10 watts peak, Your charger needs 9.6 watts. This requires the converter to be 96% efficient. It probably can't make this. Do you know if your 12v device really does need a full 0.8A? Is is that just the max rating of the charger you are trying to replace?

Really depends on the size of the battery. It puts out 1.8 amps, so if nothing else is pulling it down , it should charge in a day of direct sunlight.

Yes , the charger will charge batteries between 6v-12v so you will be ok. depending on wich "female connector" you have it should work great. and if it doesn't include the connector you need, you could always run down to your local hobby shop and pick up a adapter .

I use mine with a Marine deep cycle car battery to power lights and a tablet as a portfolio at an art fair, so yes it'll do the trick.

Yeah, but with only a 6 amp charge rate, it might take a while. The charger does work well, though. I use it for my 27 series cranking battery in my boat, which I never run all the way down. The two deep cycle batteries that run my trolling motor use a charger that has 15 amps per bank.

The voltage on this battery is 12v. The nominal chanrging rate listed for the battery is 15A with a peak charging rate at 30A. If you have a single battery with a charge controller at 30A, you should be just fine. However if you add a second battery this will drop to 15A per roughly, minus loss so you may not be able to fully charge your batteries based on your usage in a single day.

It is a very good charger, i us it on only one 12v battery currently, but i see no reason why it would not maintain the charge on your batteries as long as they are hooked as a 12v system, i am sure it would be more effective it you did one at a time and cycled them through

I doubt it would have a high enough power output to charge a battery that size... I would recommend against it.

I love this battery charger ,on 12 amps should get you charged in a couple of hours

If you look at specs on this charger it is fully automatic, amps are limited, so yes if the battery can be charged this one will do the job. If the battery has a dead cell then nothing works.

I use it to charge and keep the charge on a 12 volt 7AH battery and it works fine. No need for a charge controller because the amps it puts out are very low, so you should be just fine.

It works fine for any size battery. A slower charge is better for the battery as it creates less heat. If you are not in a rush this will work fine. For your battery, it will take it from a state of charge of 50% t0 90% in under 5 hours and will have it topped off by 7 hours or so. I like this charger so well, I'm buying two more. One to put a winter maintenance charge on all my equipment batteries, and one as a permanent install on a car. I have the 10 Amp version which I'm also very pleased with. I use in to charge my boat battery which is a little small but I'll be swapping it out for two larger batteries. It works fine for any size battery.
