Can I charge 2 12v batteries wired for 24v and the starting battery at the same time?

No. Only the two 12v at a time. I use a separate charger for the cranking battery.
923842
I only know that I can charge my trolling battery and cranking battery at once.

you can only charge 2 12volt batterys. cant charge them wired in series that gives 24 volts. cant charge 3 batteries.

Yes, I have 2, 12v in tandum and the charger automaticly goes to 24v chargeing.

I don't believe it is a 24 volt charger per se but depending on which charger you have it can charge one or two 12 volt batteries at a time So one 24 volt battery no But if two 12 set up for 24 volt yes

Actually, if you run 2 battery banks @12 volts, you would essentially be combining the two banks into 1. The terminals are tied together so positive/negative terminals on top and bottom are both the same terminal internally. You definitely need to use both terminals along with very large wire in order to provide the high amperage draw from the batteries. I hope this helps!

With a 12v dual battery setup, batteries are wired in parallel. A single Battery Tender should charge both batteries with no problem.For proof positive, call Deltran (the manufacturer) in Florida: 386.736.7900.

No, They are 2 12 volt batteries that will make 24 if you wire them properly.

if you have 12v batteries in series your adding to the voltage therefore your batteries together are 24v not 12 anymore. if they are in parallel then you will still have 12v just double your amp hours. this charger says its for 12v only i wouldn't recommend it.

I would not since the charger senses your battery and goes to float when it reaches charged state so with 2 it may overcharge a battery, also this is a very low amp charging system so it would probably not do the job on 2 batteries.

Yes,if you hook up two 6 volt batteries in series you will double the voltage to 12 volts and keep the amperage the same. + to - and -to +. Connecting the same batteries in parallel + to + and - to - gives you 6 volts but doubles the amperage. So if you connect them in series the 12 volts will be charged with any 12 volt charger. Sorry for the lengthy explanation but I wanted it to be clear. Good luck.

Only if you do in series. If you connect in parallel the same way you take off the wires its still 12v no matter how many batteries you hook up.

I agree with most all said here before. Get 2 12v batteries in series = 24v, or 4 6v and hook up in series but controller is best way to go to match your solar panel. Most quality solar panels will charge 12v and 24v. Get a volt meter and check it out as you go. A fuse is a must. Good luck

I have charged 3 12 volt batteries hooked up in series with this. It works fine. It is best if you make sure that the charge is balanced across the 3 batteries to start with.

Hi Gary, Yes. The charger has four leads and can charge 2 12V. Batteries at once. It's working great for me.

I don't think so. I tried to charge 2 12 volt batteries together for your same reason but that didn't work.

Yes you can wire as many batteries as you want theoretically. You need to hVe adequate panels to charge your battery though.

Don't connect the BM to a battery bank that is wired in series to produce 48V. Your options are to separate the batteries from each other and charge them individually with the BM or disconnect them from the system and then wire them in parallel for charging with the BM. Both of these options might be a lot of work to accomplish the proper charging of your battery bank.

Dont know if i understand your question. But it doesn't sound like it would work because one 12v panel wont charge 24v battery unless you connect two 12v panels in series.
