Peugeot 206+: Battery Discharge & Charging Issues with Absaar AB104-200 Intelligent Charger

Hello,

I have a big problem with charging the battery in my Peugeot 206 + (60 Ah - 640 a). The point is that I accidentally left it in contact in the garage (it stayed like that for a few days), which, of course, led to a complete discharge of the battery.

I started the car with cables, but after driving about 80 km and after trying to start the car the next day (after the whole night), it was impossible. I will note that after firing the car with cables and driving about 40 km, I stopped in the shop for about an hour and then it fired without any problems.

So I bought a charger (http://www.amazon.fr/Absaar-AB104-200-Chargeur-Intelligent-Ecran/dp/B00HEF5220) which charges on fast charging max 4 A. The problem is that after charging the battery to a certain values (say down to 11V) this value starts to drop to say 9.6V and starts charging again. It's always like this..

I don't know if it's the fault of the faulty rectifier or it's just that I need to replace the battery ...

Thank you in advance for your help

You have a compact cell, a garbage can.
Those few days of standing in the unloaded state only hastened his death and you wouldn't have traveled this winter anymore.

And you can check it somehow at home, is it really a compact cell? I just don't want to throw away a good battery ..

On the basis of "bubbles" it cannot be stated that the cell is short-circuited. It can only be sulphated. The decisive factor is the measurement of the voltage under the load of a charged battery.
The patient must be saved to the end. I suggest a check-refreshing charge:
1) pour out the electrolyte from the suspect cell (if it has separate cells) or from the whole-into the vessel and keep it
2) pour distilled water into it
3) charge with low current 1 / 20Q ie
4) discharge with a small current
5) pour out the water from the suspect cell
6) pour in the saved electrolyte and charge the battery.
It can work.

For several days of standing, the battery will not sulfate to such an extent that it does not hold 12V after charging, there is clearly a compact cell and that's it.
Gargling will help like a "cancer drip".
The sulphated battery will not provide electricity as such, but the voltage will be kept by a book.

then you have to make sure. Also check that the alternator is charging.

These chargers are new to .... It's best to take a normal old charger and then charge it preferably via a light bulb. These chargers soften when the battery is deeply discharged. For the future, when you discharge the battery to zero, that even the light bulbs are off, do not start the car with the cables. Remove the battery and charge it with the charger. When the battery is completely discharged, the alternator injects a very large current of over 80A into it, which is fatal for the battery.

Have you ever measured it? Have you seen how much current "takes" such a battery from the charger? I think not and what you are writing is just an assumption.

At first, not much due to the internal resistance, but when it reaches the value of a few 80A volts, it takes lightly.
And this is not just a measurement, I even have a graph from such a loading.

A modern battery, discharged below 10V is considered unusable and should be replaced with a new one. It will never have its nominal capacity again, even if it is successfully recharged.

Not true.
The battery may not reach its rated capacity, but if it is 90% good, why replace it?

Hello,


Thank you for your help

Eventually I ordered a new battery

Have a nice day
