the battery is 12v 6ah

It's quite normal to have a bubble every few seconds. Its hydrogen and oxygen electrolysis and happens whenever you put electrical power through water. This is the reverse of a hydrogen fuel cell.

Your battery contains dilute sulfuric acid which has a lot of water in it.

on the picture u can see on the battery quick charging is 3a x 1h when my charger have 4AMP u think i can use it or i shouldn't?

A 12 v charger is a 12 volt charger. I get the impression that the need to charge the battery is a symptom of.a different problem.

Lead acid batteries prefer slower longer charging regimes rather than short fast but remember that is if they are low.

A battery on a bike will be at it's optimal charge most of the time. The starting amps are soon replaced and then the alternator supplies all that is necessary.

When charging a very discharged battery it will take a hefty charge early on but as it gets closer to fully charged it takes longer to charge and trying to force it does no good

So yes, your charger is just within the battery fast charging range but if you intend to keep with bikes a specific bike charger or fancy charger like a CTEC will be a good investment.

12v 6Ah... that's a pretty small battery. What's it on?
Is it the correct size battery for the bike?
Does the bike have an electric start?

My immediate thought is that a battery that small, probably wont fare too well on a bike with an e-start that would tend to deep-cycle discharge it pretty hard on start-up. Good odds that electrolyte would be boiled by that and deteriorate, followed quickly by the plates that would tend to warp, and 'sulphate-up' as the electrolyte boils off, the electrolyte level dropping and 'silt' like kettle scale building up between the plates to create short circuits, as the plate to acid in contact area falls reducing what charge holding capacity the battery might gave even more.

So how old/tired is the battery?

What you heard that sounded like 'boiling' could be pretty much that, if battery old and tired, and of diminished charge holding, so small to start with, even a pretty moderate 'car' type battery charger, rated at say 4A could be banging in the juice fast enough to get it hot, even if new.. more so if new and not properly filled, even more if battery old and electrolyte level low (Or topped up with tap water with fluorine+chlorine from the water works in it!), and even more if battery old an knackered....

So what's it off and how old and what's the back story?

B-U-T other one is you DID take the fill-plugs out when you put it on charge didn't you? As has been mentioned when a brand new battery is put on charge the acid is electrolysed and makes hydrogen that bubbles out.. making a boiling noise... but also has to escape some how and the litte overflow 'vent' on the side IS not really enough... which is why in the instructions it says to remove the fill-plugs....

A 6 month old battery wont go flat in a month unless something else is wrong.

4-5 months old, is a measure of time, not how hard the battery may have been hammered and kerfkered in that time.

Assumption here has to be that it's probably rather tired and a bit kerfkered from lots of stop-start riding never properly charging the battery off the engine, and it 'may' not be too bad... 'may'....

As to whether you could charge it off a common a garden car charger... well you should be able to, b-u-t its a diddy mattery and I wouldn't want to leave it, unsupervised for more than maybe an hour.. or it could go pop.

Also begs question whether the boiling noise you heard came from the battery, or from a half toasted charger, or if charged in situ on the scooter, something else, like maybe the reg/rectifier getting toasted....

If the charger in question... don't use it.... that solves that one.
If battery in question.... get a new one; that answers that (unasked) question.
BUT overall, look at how you use the thing, and how much e-starting you do compared to full bore riding when the generator might be able to make a bit more electric than lamps and other equipment may be sucking.

Personally I recomend Bump-starting if the battery wont turn the engine over.....

Slight deviation from thread but in the same ballpark, I need a new battery but whats the best type? and whats the difference between factory activated and non factory activayed?
