Does it charge optima 6 volt yellow-tops AGM alone or do they have to be charged in tandem (two) to mimic a 12 volt battery?

You really don't want to do that. I have a special 6 or12 volt charger for that purpose; it's a Smart Shot charger, by Yuasa. Accumate also makes an excellent 6/12 charger. I have both. Bear in mind that if you set up your 2 (6) volt batteries in a series configuration; you're dealing with 2 separate batteries with individual and unique needs. It is definitely not advised at all! With respect, buy yourself a separate charger and use the Optimate 6 in a way it is specifically designed for; that's 12 volts in an individual battery. It is clearly my advice to "NOT" use it on individual batteries that are hooked up to total 12 volts. That way you'll have 100% conditions to obtain the best outcome. Hope this helps.

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

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.

most newer chargers have a setting for the agm gel type batteries, you want to use no more than a 12 to 15 amp preferably a 2 amp charger, kind of like a deep cycle battery less amps for longer time.. But when my charger was on the agm/gel battery settings it was showing 12 to 15 amps most of the time.. Good luck if you get one.

I don't know as I haven't used my charger other than as a 'backup'. The used Honda generator I bought was a 'companion' model that allows two 2000i generators to be hooked together. That feature takes the normal 12VDC output off the circuit panel. I needed a back up power for 12VDC. It's 8amp and won't overdraw on the generator. Mine works for what it does, charges wet-cell 12VDC batteries. I haven't had any experience with AGM (glass-grid) batteries. Regards. D. in Lacey, WA

It's only one. A 12 volt rectangular battery like a miniature car battery, They're not your usual double aa's or anything like that if that's what your thinking.

You would need to put two 6 volt batteries in series (make it 12 volts). Not enough info ?? eg: is this automotive type battery etc. As is not made to charge 6 volt battery.

It can be charged with the same 12 volt charger as a car battery. Best on trickle charge or low setting charge.

You have to hook up battery's in a series. It will charge 6 / 12 volts at a time.

According to Lifeline the maker of my AGM batteries either the gel or sealed setting will give the right voltage. One thing you might need to know is if the batteries are discharged say down to 50 or 60% you need to bulk charge with enough amps (most say at least 10%of the battery bank's capacity), so a 300 amp system would need at least 30 amps as a minimum and more would be better in order to assure a full charge is achieved. You may want to check with your battery manufacture to get the exact specs to charge with so you can get the longest life from your batteries. I just use the 180 watts of solar panel to keep my already charged batteries at full charge. Have a great day Gary

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.

Hello Jennifer, Yes, the Guardian 12V Charge Controller will charge any 12V battery. The Guardian can handle a maximum of 90 Watts input. You can use 3 - 4 Boulder 30 panels with the Guardian to charge your 12v battery. Thank you for your interest - I hope we can help you - Denis, PrepareDirect

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.

I have this on a 6 volt battery and it does keep it charged. I would probably go with the larger one for 12v as this said for 6 volt

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.

My application is different, 2 trolling motor batteries, 1 starting/accessory battery. The charger will charge all 3 batteries to full after heavy use in 1 evening, batteries are Optima Blue tops.

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.
