Capacitor bank on vehicle battery

Re: Capacitor bank on vehicle battery

i guess you are talking about connecting a series of caps so they are 14V++ in parallel to the battery?

Well I was never interested in that solution, i do have problems with batteries as well due to being a cheap ass and using used ones on my daily car. For me, the proper solution would be putting a brand new high capacity battery + making sure charging circuit is working as it is supposed to. Other than that I would check for current leaks and so on. I do not think that caps would prolong battery life that much.

Did you try using a desulphator? I wonder if those are useful.

Yes, like this
How do you think? it said that could makes ripple on a smooth level but didn't have talking about prolong battery life, but I have ever seen other site mention it could prolong battery life.

I don't know what is desulphator. Im gonna takes a time to read it googling.

Yeah, I mean kick start mechanism, Sorry. I don't know how to call it, bad english too.

did you ever experience to connect parallel caps on this battery? If this help to makes battery life last long, I would make it on my bike and car.

Indonesia? Crank by leg? Perhaps it is a motorcycle, probably 250cc or smaller. I've driven a bike that had both an electric starter and a kick-start mechanism.

"start my vehicle use starter button recently, not a crank by leg. "
-- can you rephrase?

Re: Capacitor bank on vehicle battery

Thank you for response, so I know this is applicable to makes this as a battery, but the price is so

I have read some site discuss it and mention about common radial lead electrolyte caps too.

How about add on common capacitor bank parallel with battery? not a supercapacitor.
I means that we are not changes battery with supercapacitor, but add an extra common electrolyte capacitor bank paralled with battery. Is that makes an effect to longer battery life?

I don't have an experience on supercapacitor and I have an idea to make one of them using common radial lead electrolyte caps as add on for battery (if true makes last longer) because the expensive price for supercapacitor.

Re: Capacitor bank on vehicle battery

Some people have successfully used super/ultra capacitors to replace car batteries.

As supercapacitors usually are rated for 2.5-2.7v, several of them have to be used to get about 12-14 volts or more (to survive charge voltages), usually at least 8 of them are used.
Then, two or more sets are usually put in parallel to increase capacitance but even so, this fake battery would only be able to give that energy to start a car for about 10-20 seconds. If you have a bad car that needs time to start, you're screwed.

But they're expensive... you can find some used or overstock or stuff ordered for cancelled projects on eBay... those supercapacitors are about 30-50$ a piece and when you need 8+ of them...

So yeah, it still costs a lot, but on the other hand you don't have to buy batteries every again.

Hi everyone, anyone on this forum ever makes a capacitor bank for vehicle battery?

I have read some site that said about this and they are mention about this could makes our vehicle battery last long and didn't hard to start.

I have a problem to start my vehicle use starter button recently, not a crank by leg. (maybe different with others country vehicle that automatic mode vehicle)
I have try to fill it with chemical battery water and charges it using UPS, but it is still hard to get start.. maybe it was defective already, and after buy the new one, I think to makes this if really could makes my battery last longer.

So the question is this capacitor bank really applicable or just a hoax?
