I have 3 AGM house batteries in parallel on my motor coach. Will this unit charge all of them at the same time in this configuration, and not overchrg

Not positive here, but I would be hesitant to use this charger for that purpose and I wouldn't even dream about it if they are in series. (I would dare to believe that they are parallel though.) I would feel okay with 2 standard automotive batteries wired in parallel, but I think you are asking for a short lived charger on anything more than that.

AGM Batterys have the same charging specs as Lead Acid battery' (shttp://www.bdbatteries.com/mcharging_procedures.php) so no problem. The charge info is found here (http://www.progressivedyn.com/prod_details/rv_conv/rv_converter_pd9245c_2.html).

I have a Renogy 40 a controller with three of these batteries in parallel and the system works great! The VMax website provides all the details you need on their batteries. Just remember that when hooking up the charge controller to hook up the positive at one end of the string of batteries (in parallel), and the negative at the other end.

Yes, I feel it charges all my batteries properly. I have used it on conentional, deep cycle , and AGM batteries. I select battery type and like to use the percentage readout and watch till it it reads 100%. This can take longer than you might expect as I think it tapers off as battery fully charges.

Yes, it will just take twice as along if both batteries are in the same state of discharge. Depending on how your two batteries are hooked up you may be charging both anyway.

Thanks for your inquiry. The batteries would have to be connected in parallel, not series, in order to be charged.

I am not using it on AGM batteries, but they are just lead acid batteries in a more efficient configuration, so I wouldn't be afraid to use this battery charger on AGM 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.

Yes, you can charge only 1 battery at a time. I do this often. I find that this charger works very well and I like it.

Any 12 volt AGM charger should charge your battery bank. The calculation that you need to consider is how fast you want the battery bank to charge and size your charger appropriately. Yes, this charger has a battery type mode to accommodate AGM battery types. Looking around on the internet, this battery charger on its highest setting of 70A should charge your bank of batteries in 14-18 hours.

I've used it fo 2 31series batteries I think it would depend on the size and condition. It would probably maintain them but I dont think it would adiqilutly charge 4 batteries unless they were small

in my opinion this charger will charge your batteries as it has a agm setting which is good for your batteries but just to be sure seeing the size of your batteries and the expense of them I would go with a bigger amp charger

No, not in my opinion. This unit will recondition and charge a very low AGM battery while most charger won't. Optima also offers a smaller trickle unit that will insure your AGM stays healthy assuming your AGM is in a vehicle that sits more than it's driven - or boat...

Absolutely, my batteries are the size of electric wheelchair batteries which are made to run all day without a charge. I charge 4 at once. I use a smaller charger (same Make) to charge my car battery. I would recommend this one because you can select a trickle charge first. Too much charging will ruin your battery. even 6 amps is not excessive.

hi I have had good luck with it charging two batteries at the same time for my tracks Slash I think those or 7 volt batteries but I like it it works for me

I assume you are talking about two 12v agm batteries hooked in series, that are then connected in parallel to a 24v source. First, battery minder makes a charger for agm batteries vs normal car batteries. Second, to be safe, if there were a way to disconnect the two 12v batteries from each other, and from the 24vsource, you should be able to charge them individually (red clip to + terminal on battery and black clip to a ground point on the vehicle). Do not attempt to charge while connected to 24v source or while the two batteries are connected together.

It would charge it, but not to quite full charge. It is not the ideal charger for an AGM. They require a little more voltage. This also is not a "smart" charger and can overcharge a regular battery if left on too long. If nothing else get an upgrade from this one.
