Capacitor bank on vehicle battery

Re: Capacitor bank on vehicle battery

thank you for video suggestion, I will see that.

Just do the math like i did, calculate the needed energy for starting the engine, measure the current or something. Check the starter motor, or at least its fuse if it has one, to find out how powerful it is. Or please state the model of your motorcycle, somebody will be able to find it in the internets.

Just an idea: it sounds that there is some problem with fuel/air mixture, timing, carb/injection system, compression.. I mean, if it takes long time to start the motorcycle, 4-6 starter cycles is a lot, then it might be that the battery is not a core problem, it is more a victim of a problem.

How does it start if you charge you battery with mains charger and try to start it just instantly after that?

That's good idea, i will find my model and data of motorcycle. I think the battery were defective because it has white chemical oxidation looks like a salt(I don't know how to call this) on battery connector, makes the connector rusty (but still strong enough and hard to remove it with screwdriver), so I just using warm water to clean it and wipe with WD40, after 2-3 months that chemical reaction appear again.

Re: Capacitor bank on vehicle battery

Ok. I just try to search any specifications on internet and find this, hope this give some idea for help me domas

I can't see any pdf file to upload so please forgive me if you have to takes a time to open and read the site. the bottom site is my country site so it needed to translate. thank you very much for your attention.

Typical remedy is water and baking soda. I don't know what you imagine when someone says to clean the connectors, but when I (being someone who's restored/wrenched on cars for almost 20 years) tell someone to clean their connectors, what I mean is to disconnect them, get all the corrosion (white stuff) off with a wire brush if need be, then use a battery terminal cleaner to scratch the contact surfaces of both the post and the connector... of if all you have is a steel-bristle brush or the like then use that to scratch the contact surfaces. It makes a big difference! Don't put WD-40 on the surfaces. Make sure that the GROUND cable has a very solid, very clean connection at the other end--should be the frame of the bike.

Thank you for your reply
I don't have experience before so I don't know how to clean it well, btw hot water or just cold water from pipe? this knowledge is very useful. So we just clean it with wire brush and mix it with water and baking soda if hard to remove the connector?

Re: Capacitor bank on vehicle battery

Hot water dissolves the baking soda better, and you use a stiff brush you no longer like to brush clean the whole top of the battery. Then rinse well with cold water and wipe dry with a clean paper towel.Battery posts clean to bright lead and same with terminals and leads. When attached use a can of battery terminal protector to coat them with a thin coat to keep them from corroding again. If you do not have this then wipe with a thin coat of vaseline over the outside of the terminal, though this will attract dust like magic. While you are there check battery water level and refill if needed with distilled water. If it is a "maintenance free" battery with a sticker on top pull the sticker off and then you will find the caps under to check water level, and it is likely to be low.

Re: Capacitor bank on vehicle battery

There are some specialty batteries available that have high current and deep cycle but you pay a heft premium for them. Try the coiled cell lead acid batteries for best of both worlds.

Re: Capacitor bank on vehicle battery

maintenance free battery couldn't refill as I thought, I have ever did it and no luck, battery still dead.

Hey, this circuit and cleaning trick gives me a good starter engine again, yesterday I was trying makes this caps and clean the battery (measured 12v on my meter) so I think this worth to try. and guess what? my engine didn't hard to start anymore. it just needed 1 times to start !! thank you for advicing.

Btw how it looks when you mean thin coat? veseline like skin beauty care veseline? correct me if wrong I don't know how it looks, I want to prevent this corotion again because this is annoyed me to have to clean it every 2-3 months.

Re: Capacitor bank on vehicle battery

Yes the beauty stuff. It's just petroleum jelly. It's clear and thin and melts to spread over the terminal. Anything that forms a seal will work. You just have to keep air water and everything else off the metal. Even grease will work but it's black and messy. A thin coat would mean about 1 or 2mm, the heat of the engine will make it spread out.

Re: Capacitor bank on vehicle battery

Permatex sells a protectant for battery terminals that becomes rubbery and purple when dried. It's meant to be applied over 100% clean terminals, after they're tightened. OTOH if grease is used instead, it should be applied before assembly so it seals the gaps. The grease won't block current flow because the asperites on the posts and terminals pierce through the film.

Re: Capacitor bank on vehicle battery

Thank you for new knowledge !!

I haven't know much about engine before, this thread makes me learn many things

Since this circuit and cleaning tricks doing well, I'll be attach some veseline likes you'all suggest to prevent any future corrode.
