It starts more sometimes, a quick charger 3mn then in assistance mode start charger in 220v

It starts, so it’s not a lot of power that the battery is missing but it’s missing.

Chronology

2 3 months ago noise of a squeaning belt

10 seconds then never again/

Tension do you have the frequency of the alternator belt because I tuned /tensioned the air conditioning to 122 hz,

And there a laternator I have 99hz

The key is 23 for the pebble?

To tighten it is like the air conditioning, wooden baton on pebble we press and tighten the torx in key (not evident alone! But already done)

I put the battery in slow charge yesterday out of the car 3h and it indicated yesterday 13.4 V and this morning 12.4 (figure that allows me to start according to my maintenance books)

Bad sign?

I recently had a problem with a connected box that tells everything to my insurance in obd2 so it may be tempted to connect all night in 4g.

But he’s disconnected now.

I also changed the radio and its price was very low on the boncoin so shady, with the battery at 12.6 when I turn the key and car radio and it doesn’t work we go to 12.11 and it falls to infinity slowly

Test on the car battery off no amps flying secretly. (Voltmeter in series at the + terminal)

I would like to do the maximum before changing the battery

Thank you for your advice

Apparently I’m missing 150 hz

We’ll have to tilt the alternator a lot,

Is it possible to tighten the belt without disassembling the air conditioning belt?

Thanks

Test voltmeter engine running 13.4 if I accelerate it goes up to 13.6 if I turn on the radio no incidence.

The belt is quite secure at 1/4 turn

Thanks

I can’t understand much of anything you are posting. Most posters here are from the USA. If you are driving a Renault Twingo, you are not in the US as we have not had Renault vehicles here for 40 years. I assume English is not your native language.

Since this is your only question:

And we know little to nothing about Twingos, so I’d say Sorry, we can’t help.

It sounds like this car does NOT have an automatic belt tensioner

And it seems to be charging at 13.4V at idle . . . that sounds okay, given I know very little about a Renault Twingo

How old is this battery?

Is the electrolyte level correct?

Do you have some way to perform a more proper test on the battery for free?

do the auto parts stores in your country test batteries for free?

Hi thanks dor your reply
I am not sure how old is battery but I have slow charging low level charger and have only done a 3hour charge.

Not sure about ectrolyte so all batteries allpw to check? Or some sealed

Yes I can do more test what do you suggest? Havent tried ripple one

Not sure about stores helping they will probably want $$$

Thanks

Do you have access to something like that?

They’re pretty cheap

Have you verified the current draw with a digital multimeter?

50 milliamps is generally considered the maximum allowable value

Does your battery have removable caps?

What does the current draw show?
Which current drawn?
Thx

With that type of charger, it may take 12 hours or more to recharge the battery. Depending how much the battery was discharged.

Yes, good idea
Some websites say healthy battery should be at 13.8 so looks like Its a little low
(When running)

With the engine running, the voltage should be 13.5 volts or higher.

If it’s closer to 12 volts, the alternator isn’t working.

engine off batt volts should be higher than 12volts (higher than 12.5 is preferable.)

During cranking, battery voltage should stay over 10volts.

Engine running volts should be over 13.5 volt.

anything different means you have an undercharged battery or some other issue.
