Will this charger maintain the charge on a bank of 4 AGM D31M deep cycle batteries connected in series? Thanks!

being an electrician for Chryslers you might think I would know this. The float chargers that we use at Mopar were huge for the batteries that we charged for the carts that are used. They were ran in series also. I do not think this would be what you need, but it wouldn't hurt. I would call a battery wholesaler or ask this question on google.

Not sure as AGM is a brand I have tested deep cycle batteries with mine and had results as expected

You would have to put 4 batteries in series and all would have to be in about the same condition--not an optimal method. you would be better off putting two 6 volt batteries in series on a 12V charger

Repoleved pretty much answered the question. It depends on how much you use the battery and how much you drain down the charge. Mine runs a circulation pump for my solar water heater. I have a 12 boat (deep cycle) and it always seems to keep it charged up. When my panel arrived it had a cold solder joint and I had to re solder it to make a good connection, and you need to figure out how to mount it.

I would not use this charger on a AGM or gel batteries. It has a voltage ramp-up (15-16 volts) periodically to reduce accumulation of sulfites on plates which is not good for these types of batteries.

I use a Genius G3500 Charger/Maintainer. It has a special charging mode for AGM batteries. Just make sure to use a charging system that is smart enough to charge and manage AGM batteries. By the way, the Vmaxtanks MR107 12v 85AH battery is wonderful. I highly recommend this product.

I am not sure that the Battery Tender Junior has the sophisticated electronics that the 4 up Battery Tender Plus does. I have been able to keep 4 ea. 27 size deep cycle batteries at maximum voltage and CCA for two years since I got my 4 up unit. I believe that the Battery Tender Juniors are designed more for smaller batteries. You would have to talk to the people at Deltran for a more detailed answer to your question as I am not an electrical engineer. I really like my 4 up unit.

according to their spec sheet it does, but after calling them i found the cut off voltage (total absorption rate) is 14.7v to each bank. that's fine for AGM batteries but Gel batteries are only supposed to be charged to 14.1 and overcharging will definitely shorten their life !!! there are no switches or modes on this charger so buyer beware !

No, but make sure your charger charges this AGM battery with the proper voltage. AGM batteries require voltage of slightly over 14 volts

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

I cannot answer that question. I think from all I have read about this charger it cannot overcharge or undercharge its built into the charger. I use mine to charge my boat trolling motor and when the green light comes on I always disconnect it. I have never left mine on to continually charge. Some battery chargers will damage the battery if they don't switch to the maintenance cycle. But once again I think this battery charger it's all built in to not overcharge. That's why I bought it. Hope this helps some. I am just telling you how I use mine and I have never left mine hooked up past the full charge. Sorry.

This charger can definately maintain that battery. It will work on any 12 volt battery. It will automatically pick its charge rate based on whatever battery is plugged to it. Once the battery is fully charged it will go into float charge mode and act as a battery maintainer, so it can be plugged in indefinately. Great charger

Shouldn't be a problem with DC current, Better to have a continuos extension without multiple connectors (length not too much of an issue). it's best to check with manufacturer of the charger.

It probably does, but keep in mind that different batteries require different floating voltage ("maintenance mode" in other words). This charger has no voltage adjustments. For an expensive AGM battery you will want a better charger, the one that would allow voltage regulation, and also has a temperature compensation.

If the generator has clean output I see no reason that the BatteryMinder AGM could fail to charge a big AGM battery. A cleaner solution might be to charge the bank direct from the solar cells, as long as the solar array doesn't have enough power to overcharge the AGM bank.

I can't speak to 5 batteries, but I have 4 yellow tops connected together in my solar array and hook this charger onto the side posts of the last battery and the charger maintains all 4 without a problem. It may make a difference - series v. parallel - I have mine connected in parallel.

Yes, But will not charge at 1C rate. Max charge rate when using all four slots is 1000ma. Max when using two slots is 1200ma. i.e. around two hours charge time. Normally charger must put in about 110% of discharge current if battery is in good condition. Really like this charger because each slot is independent and retains values after both charge and discharge.
