How do you hook more two batteries together? In parallel, I assume? And this would double the battery usage time, correct?

That's what I've done. I don't know that it "doubles" the usage time but certainly extends it. I also periodically use a battery charger to "boost" the batteries.

Refer to "The Twelve Volt Bible" available at Amazon.com - will answer all your questions. That's what we used.

The batteries may be wired together in either parallel or series configurations - depends on your needs.Parallel wiring = increased amp/hr rating at same voltageSeries wiring = increased voltage at same amp/hr rating

Yes I have 4 hooked up. Just connect all the positives and all the grounds to the battery u connect to

You need to make sure of a couple things. #1 the Batteries ideally need to be bought at the same time as a pair. #2 at a minimum the batteries need to be the same class (capacity) and close to the same age.Otherwise you will not have even charging, one battery will charge fully, and actually discharge itself to bring the other battery up to its level of charge.You must use deep cycle batteries. Standard car batteries are not designed to have a constant drain down and recharge like deep cycle's are.

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.

Rajesh, The more 24 volt batteries you hook in parallel the longer hours of output you will have. Joe

Don't connect the BM to a battery bank that is wired in series to produce 48V. Your options are to separate the batteries from each other and charge them individually with the BM or disconnect them from the system and then wire them in parallel for charging with the BM. Both of these options might be a lot of work to accomplish the proper charging of your battery bank.

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).

Battery Tender site indicates multiple batteries can be connected in parallel. They need to be the same type and voltage but do not need to be the same capacity. If the connectors fit or can be made to fit, I think this would work as long as total capacity is within limits stated on Battery Tenders web site. For storing batteries over the winter, I would probably charge all batteries separately and then connect them in parallel using this or direct connects. I plan on taking a closer look at purchasing the item :-).

You can use it taking off one and using the other but not two at the time. This battery comes like two OEM batteries connected to eachother, one is bigger than the other. You take off the OEM battery and put unstead the extended one, and put on the case that comes with it.

There are several ways to do this. For a parallel connection: The absolute rule is that positive (+) goes to positive and negative (-) goes to negative. The easiest way to wire them in parallel is to make two pigtails for each battery. Use wire no smaller than #16 gauge stranded, #14 would be best. Having two colors, preferably red for + and black for - will help you keep things in order. Buy four female and two male insulated quick-disconnect (fast-on) crimp terminals of the right size to fit the battery terminals. These are 0.25-inch terminals. Radio Shack 64-3049 has a kit of four of each. Crimp a female terminal to just one end of each pigtail. Skin and twist together the other end of the two black wires and crimp one female terminal to them. Do the same for the red wires. Plug negative male connector from your load to the black wires. Do the same with the red wire. Use electrical tape to cover each connection. Plug the black pigtails to the battery negatives. Plug the red pigtails to the battery positives.

Do you mean what type of battery, if so it takes three Double A batteries. If this is not what you want to know, please add a little more info to your question.

on top of the batteries there is what looks like a flip up handle - if you flip it up you will see the inlet for the plug, you just plug in the charger and align the pins and plug it in. When fully charged do the other battery.. I bought a second charger so I can charge both at once. But I don't think I would invest that much again. I have a broken bike in my garage. Have had to replace the back rim which is not cheap and the new rim broke within a few weeks -- if you can sell it do so - they are not built with strong enough back rim and spokes

You can hook up as many batteries to it as you want man just make sure its 12 volt series. Like I have 4 batteries I took off of oil pumps and I connected them in a parallell series. Like I went to auto zone to get the wires to hook it up from one battery to another and then from the battery to the power inverter but I only used one positive and one negative bolted on to the inverter I didnt use all 4 and let me tell ya haha this thing powers my while cabin like a champ!

When you connect them like this, they operating in parallel - same as if you had wired the batteries in parallel yourself. Each battery will receive the same charging voltage. For some batteries, this this will be the correct charging voltage, However, the other batteries could be over-charged or under-charged. All the Battery Tender sees is one battery! This is answered on the Battery Tender website. The explanations are excellent, with clear diagrams. Find this info in the education section - it's a on pull-down tab, at the top of the homepage. A good reference for all battery charging and connection questions.

I have an additional thought to your answer Kurt. While it may be true that the unit auto switches from 12 to 24 volts for two batteries. If more than two batteries are involved (in 24volt configuration) Additional batteries would have to be by two and in parallell. If you start with one battery (12 volts), just keep adding in parallel. Personally I would just assume hook up one battery at a time ...charge it up fast...then hook up the next one.

According to the hype, you can charge up to 4, 12 Volt batteries at once? However, I could not get it to work?

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.

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 don't think you should try using adapters and more battery than this supposed to take 1.5 volts each adding to many 1.5 volts can break it and they will not last as long d is a lot of power just use the d I say
