would this keep a permanent charge on 2 12v batteries

Hard to say. How big are the batteries? How much ambient sunlight does your location get?

Sure! It's a 12V battery, just not a big one. One caution, though. If you are using these in series (like, in a Razor scooter), you must disconnect at least one of the connecting leads between batteries. Otherwise, it's a 24V system, and your 12V charger won't work.

I have it charging two deep cycle 6 volt battery's wired in series for 12 volts on my camper works great for that. I would think it will charge any 12 volt system, larger would just take longer.

Yes. I use mine to keep a deep cycle 12V marine battery charged. 12 volts is just a nominal term for the average target output of a battery used in a 12V system. When fully charged, all batteries exceed their rated voltage.

If your 1amp charger is 12 volt AND you charge the batteries 1 at a time. I use my 2 amp charger from time to time.

This is a smaller battery, I can fit 2 of them in my battery box. it is 12 volts so yes it will work but will be half the capacity

yes; but just remember this unit is just a trickle charge. It will keep it up, but real slow. Also make sure your batteries are topped off with distilled water.

Yes, but...If you have room for two batteries, it's more efficient to use two six-volt batteries in series rather than your idea if using two twelve volt batteries in parallel. In a parallel installation, the two batteries, even if matched in capacity and age, usually have slightly different charges and the lesser charged battery sucks current out of the other one. So the battery bank tend to self discharge. Two six volt golf cart batteries are your best bet.

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.

Yes, but beware, you probably want to charge more than just 1 battery, more like a small bank of batteries. For example, I have mine hooked up to a small bank of 8 SLA 12V batteries giving me about 1500 watts stored to power a 1200 W Inverter for appliances. It's like a solar powered battery pack so that I can work and have phone conversations in the most odd places (no generator noise in the background, just pure silence or nature noises, it's awesome). You'll want a decent charge controller (I bought a 10 Amp controller, which is overkill, but has the better charge-methods and pattern that I wanted). Good Luck!

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

I've used it for two 12V batteries that power the electric motor in my boat.

No, not recommended. If the required load to maintain the two batteries (assuming they are wired in parallel) is unbalanced, this can damage the charger. These are cheap chargers, save yourself some grief and buy two.

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.

I use a heavy duty car battery with my 12v power inverter and so far it has keep the battery charged.I am very happy with mine.

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

no as long as its a 12v battery it will charge it, the bigger it is the longer it will take.
