You can connect as many 12v batteries as you like. You just need to make sure to connect them in parallel, if you connect them in series you will have some serious problems.

yes, you can connect the 12v batteries in parallel. It is best to use deep-cycle or marine batteries for this application. Parallel battery hookup will maintain the 12v, but extend the amp-hours rating of the entire set of batteries. Hooking up batteries serially will have an additive effect on the voltage (eg. two 6v batteries hooked up serially will output 12v).
1615005
No problem at all. Just connect 2 or more 12v batteries in parallel. I use 4 x 12v batteries.

These inverters are commonly used with multiple 12 v. batteries. They need to be wired in parallel --pos to pos, neg to neg. This creates a "bigger" 12 v. battery, but the voltage at the terminals is still approx. 12 volts. With this configuration multiple batteries will charge at the same time. ALWAYS use identical batteries of the same age/capacity as one bad battery spoils the bunch.
1615007
Sure, you can use more than one 12v battery, but the multiple batteries must be wired in parallel, NOT series. "Parallel" means like terminals (+/-) must be wired together. You should consult an electrician if you aren't sure how to do this. I'm not sure about charging capacity - I suspect it will take longer to re-charge multiple batteries. You may want to ask Tripp Lite about that.

Yes: you can hook up as many 12v batteries as you like. We have many of these with up to 4 batteries connected. IMPORTANT: If using 12v batteries, just be sure you hook them up in parallel, not series!!

I do not know. I assume you are hooking them parallel (? Is that right?) to keep the voltage at 12 volts, but longer run time. I have a deep cycle cell on mine, but have three motorcycle batteries and I have been thinking of doing this to get maybe more amperage. Don't know if there is more amperage. I don't know why you could not hook more up as long as you don't increase the voltage. How do they show hooking up the two motorcycle batteries? To get more amperage at 6 volts or increase voltage to 12? Sorry, a lot of blather here without saying much. I would be interested in what you decide to do. Good luck. I do not know.

I've always used them with two cell flashlights. If the six batteries are in series (- of one battery against the + of the next battery and so on), then you'll increase the voltage but the overall power capacity remains the same. For example, two 1.5 volt batteries in series gives you three volts, but overall should have the same overall power capacity as one 1.5 volt battery. Six would be 6 x 1.5 = 9 volts. Now Having said that, I have recycled nearly dead batteries into flashlights with these LEDs and still get very useful amounts of light for several more months (where the conventional flashlight bulb would have become too dim to use). Hope that helps, Joe

All batteries of the same amps can be used in series with no problems!the 12v in series may actually come down to 24-28V, as these li batteries give a tad more voltage; so make sure you got a good charger!
2070265
yes that is correct. If you connect two 12v batteries in series end result will be one battery bank of 24v. When charging batteries - use of a charge controller is highly recommended.

Hi Shard, my initial assumption is that you do not have the connectors in the right place. The batteries are connected in series i.e. mine are 6volt batteries and I have 6 of them for a total of 36v. So the positive connector has to be on the 1st batteries positive terminal and the negative connector has to be on the negative terminal of the last battery. If you have it hooked up that way, one of the batteries might be bad. Bill

It was pretty easy....take a wire from the positive side of battery #1 and a wire from the negative side of battery #6 and connect them to the 36v input wires. I think they are the black and yellow wires on the voltage reducer. It's marked on the bottom and I believe its marked 36v. Then you connect any 12v device to the other two wires, which I believe is the black and red. Again, the input and output are marked on the bottom of the voltage reducer. Works great and only takes minutes to install. Good luck.

Depends on what type of battery you have, Susan. Here is a direct quote from my owner's manual: "This system is designed to be used ONLY on vehicles with 12 volt DC battery system. Do NOT connect to a 6 volt or 24 volt battery system." The caps are mine to stress that this unit is only for 12 V systems. So far mine has worked flawlessly and I hope you have a 12 V battery so you can enjoy the same performance that I am. Good luck! Chuck

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!

You can use for more than one light as long as it does not exceed the manufacturers recommendations. If you are using 12 volt lights you MUST also use the Intermatic 120vAC to 12 vDC transformer.

The unit I got was preset to 11.99 volts output. I used a voltmeter to set it to 12V output. The input accepts a range of voltage and does not need to be set. I connected my 20V and then 12V rechargeable batteries and the output voltage did not waiver.

Two 12V batteries in series can be connected to a 24v charger, but you want to make sure they are both in approximately the same condition. Two batteries in parallel doubles the capacity, but not the voltage so you can not connect them to the charger as the parallel pack is only at 12V
406500
Yes, two of them. Make sure they're alkaline as it likes higher voltage (NiMH has a tendency to not work well)

These units were designed for use on a single battery and not "6" connected in a series or parallel. You can check with the manufacture about this issue but my guess is it will not work with 6 batteries.

A battery is a battery and voltage is voltage. If the machine will run from 12V DC there is no reason you couldn't use it. I would have to imagine there are better solutions for that though.

Go with two high current 12 volt deep cycle batteries. Wire them in paralell; not series. You only want 12 volts; not 24. Use the same brand/capacity and type. Don't mix brands or current ratings. THE HIGHER THE CURRENT RATING;THE MORE TIME YOU'LL GET ON THE BATTERIES. I've seen systems with more than two batteries however, you'll need additional equipment to pull it off safely. You could also use a marine A/B Battery transfer switch and draw from bat A bat B BOTH of OFF. Don't forget to use fuses at key points. Amazon also has some pretty good books on the subject.

We recommend using two PP-12-L units when you are using larger 6 volt batteries in a series parallel connection. We suggest placing one on each of your series connection. When you are using one unit, it will cover the two batteries well but as the pulse wave goes out, the wave diffuses. It is like throwing a rock in a pond and as the waves go out they diffuse. But if you throw two rocks in the pond on each side, the waves cover the pond equally and quicker. You will want to create equal resistance levels in the batteries as they are desulfated.

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
