You use a small LiFePo battery or a small lead-acid battery WITH supercaps. The supercaps will recharge in a matter of seconds to a few minutes and you'll be able to try over and over. Actually, you should in theory get substantially more crank attempts with a small battery/cap combo than with a standard lead-acid. The cranking current comes from the surface charge of your lead acid battery and you use that up very quickly at high current. Not to mention, greatly reducing the life of your battery. The caps on the other hand don't need the battery that's recharging them to be all that powerful. If you charged them in parallel and discharged in series, you could, in theory even charge them with a few AAs (would take a long time though). <br /><br />Btw, if you can't get the engine cranked in the amount of times a supercap+battery setup gives you, there's a problem somewhere else.Anonymoushttps://www.blogger.com/profile/05354264938488937312noreply@blogger.comtag:blogger.com,1999:blog-8658221316008750389.post-30284343576011139922017-02-10T12:49:06.178-08:002017-02-10T12:49:06.178-08:00That's not much :(That's not much :(Anonymoushttps://www.blogger.com/profile/03291222807206802813noreply@blogger.comtag:blogger.com,1999:blog-8658221316008750389.post-45440234125656189422017-02-09T17:31:04.070-08:002017-02-09T17:31:04.070-08:00Hi Victor, it differs from car to car like the kw ...Hi Victor, it differs from car to car like the kw rating on the starter motor.

First of all, you are asking to do somethin...Hello<br /><br />First of all, you are asking to do something that capacitors never really where designed for in the first place. I would advice you if you are going to replace your cars consumer battery with ultracapacitors you really need to do some calculations and measurements first, as to how much power the onboard car electronics really are pulling and for how long you are planning on using them between engine starts. <br /><br />It's been said in the comments that a 9 watt led bulb lasted for about 40 minutes with six 2600f capacitors. So you will then only get around 10 minutes of use if that load is around 35 watts. So in this case an ordinary battery would do a much better job.<br /><br />There are no guarantees when it comes to new types of car electronics and control units that it will work without problems. But your 190 Amp alternator should not have any problem charging the ultracapacitors even if you decide to go big. To keep things safe you can also add what's called a Super Capacitor Balancing Limit Voltage Protection Board.<br />About Supercapacitorshttp://2600f-ultracapacitor.blogspot.com/2013/03/ultra-capacitors-vs-car-battery.htmlnoreply@blogger.comtag:blogger.com,1999:blog-8658221316008750389.post-79322178337477087022016-08-05T02:03:14.816-07:002016-08-05T02:03:14.816-07:00Hi Simon, I have a VW Touareg with two batteries--...Hi Simon, I have a VW Touareg with two batteries--one for starting (110Ah, sealed gel-type) and one for consumer electronics (94Ah, sealed AGM type), alternator is rated at 190 Amp.

In fact many people that use aftermarket car audio amplifiers will also install a car audio capacitor to help stabilize the voltage. <br /><br />The thinking behind this is that high power amplifiers draw large amounts of current from the vehicle's battery and alternator. And when adding capacitors to store electrical energy to transfer that power to the amplifier it is easing the burden on the alternator and electrical system.<br />About Supercapacitorshttp://2600f-ultracapacitor.blogspot.com/2013/03/ultra-capacitors-vs-car-battery.htmlnoreply@blogger.comtag:blogger.com,1999:blog-8658221316008750389.post-72486627235986503622016-07-28T08:59:36.352-07:002016-07-28T08:59:36.352-07:00can i add Ultra Capacitors to my car batterycan i add Ultra Capacitors to my car batterysimonleyohttps://www.blogger.com/profile/14826474016383984599noreply@blogger.comtag:blogger.com,1999:blog-8658221316008750389.post-80392481024135094252016-07-28T08:58:57.495-07:002016-07-28T08:58:57.495-07:00This comment has been removed by the author.simonleyohttps://www.blogger.com/profile/14826474016383984599noreply@blogger.comtag:blogger.com,1999:blog-8658221316008750389.post-64652838492859527032016-05-05T20:18:59.318-07:002016-05-05T20:18:59.318-07:00Hi Fauzan Izhar, that should work fine.

But it's better to have a large alternator if you also use large capacitors like the 3000 F ones because they need more Amps to charge.<br /><br />So I would only see a problem if you have very large capacitors like the 3000 F ones and they are almost empty (like way less than 10 volts, but somehow managed to start the car). And then you have a small alternator. Then it would take a much longer time (about 1 minute) for your alternator to charge them back up. <br /><br />If you are worried and you know you have a very small alternator fitted to your engine that can supply much less than 65 Amps. But also have very large capacitors that need to charge back up from empty then I would try and help the alternator with an ordinary battery to take some of the load off the alternator. Best would be to fit a bigger alternator, or use smaller capacitors. Even six 300 F capacitors will start an engine.<br /><br />About Supercapacitorshttp://2600f-ultracapacitor.blogspot.com/2013/03/ultra-capacitors-vs-car-battery.htmlnoreply@blogger.comtag:blogger.com,1999:blog-8658221316008750389.post-40920312612982672112016-05-01T21:06:42.570-07:002016-05-01T21:06:42.570-07:00Can the car's alternator charge the ultracaps ...Can the car's alternator charge the ultracaps like normal?

There are people starting cars with only six 20 F capacitors (that's twenty farad x six). And six 350 F capacitors have no problems starting a cold V6 on a winter morning.<br /><br />So it does not take much to crank an engine with supercapacitors. Perhaps you have a bad capacitor and that's what causing problems for you. <br /><br />You could check how they are connected, some super capacitors have 3 post in a V shape and on the newer capacitors the terminals are negatives not positive, and only the center terminal is the positive.About Supercapacitorshttp://2600f-ultracapacitor.blogspot.com/2013/03/ultra-capacitors-vs-car-battery.htmlnoreply@blogger.comtag:blogger.com,1999:blog-8658221316008750389.post-7971193178353596852016-04-04T09:01:19.424-07:002016-04-04T09:01:19.424-07:00I am wanting to replace my car battery with superc...I am wanting to replace my car battery with supercapacitors. I placed 6 2.7 V 500 F supercapacitors in a series to get a total of 16.2 V and 83.3 F and it did not turn my car over. the voltage instead dropped from roughly 14 V to about 6 V. I do have a V8 though, I also tried this on a 4 cylinder and got the same results. I am wondering how big the supercapacitors have to be in order to start a V8 or if I just have bad supercapacitors. <br />Thanks, Clayton Anonymoushttps://www.blogger.com/profile/16569359024558859669noreply@blogger.comtag:blogger.com,1999:blog-8658221316008750389.post-71213407827024418122015-12-15T19:39:52.440-08:002015-12-15T19:39:52.440-08:00Hello Zephod, that's a good idea if you can fi...Hello Zephod, that's a good idea if you can find a good deal on these for the right price. <br /><br />The specs for the BCAP0010 2600f ultracapacitors say they are rated at 600 Amps and the rated discharge 0,3 - 30 seconds. So considering this they are much more suited for high load situations for a limited time.<br /><br />If you charge the six of them up in an array to 14 volts you can run a small microwave in your motorhome for a few 3 - 4 minutes with the 2600f capacitors. And by the end they will have discharged to about 11 volts. <br /><br />So they are not empty by that time but it really shows that you won't get much Amp Hours from them.<br /><br />Someone else did a test with a 9 watt led bulb and that lasted for about 40 minutes with six 2600f supercaps. I would advise you if you have room for solar panels on your motor home you could use that for charging them up, that way you could make sure they always stay charged and you would always have power to heat some food or perhaps make some coffee.About Supercapacitorshttp://2600f-ultracapacitor.blogspot.com/2013/03/ultra-capacitors-vs-car-battery.htmlnoreply@blogger.comtag:blogger.com,1999:blog-8658221316008750389.post-33276646319953909102015-12-15T07:46:21.375-08:002015-12-15T07:46:21.375-08:00I'm interested in combining supercaps with a c...I'm interested in combining supercaps with a conventional battery in my motorhome.

I can only guess that perhaps having 6 even bigger 3000 farad capacitors pull a bit too much amps for the alternator if it's only rated for 65 amps. If you left the car sitting for a week you might be down to 10 Volts and charging them back to 14 Volts would take 30 seconds, so not that long of a time but who knows maybe it would be too much for the 65 amp alternator to charge them up in one go. You could give the resistor a try considering the price of a resistor is nothing compared to having to buy a new alternator. But I would not rule out a faulty alternator either.About Supercapacitorshttp://2600f-ultracapacitor.blogspot.com/2013/03/ultra-capacitors-vs-car-battery.htmlnoreply@blogger.comtag:blogger.com,1999:blog-8658221316008750389.post-73548001098817869272015-11-02T14:50:03.796-08:002015-11-02T14:50:03.796-08:00I have tried 6, 3000 farad capacitors in series.

However 3000 farad supercapacitors are becoming more affordable now also. You can go as low as to use 300 farad capacitors to use as a 12 volt car battery replacement however you are running a greater risk of running flat using so small capacitors. <br /><br />The 10 farad capacitors would not have enought power to crank your engine or run much of the electronics in todays car, but you might be able to use 10 farad capacitors to replace a small battery but that's about it.About Supercapacitorshttp://2600f-supercapacitor.blogspot.com/2013/03/super-capacitor-vs-car-battery.htmlnoreply@blogger.comtag:blogger.com,1999:blog-8658221316008750389.post-67914480230879778492014-07-01T20:35:21.137-07:002014-07-01T20:35:21.137-07:00whats with the 2600 farad is that mandatory or can...whats with the 2600 farad is that mandatory or can i use the 10 farad 2.5v ones what will the difference be Anonymoushttps://www.blogger.com/profile/12982205148480743031noreply@blogger.com
