Battery or problem electric leakage ??

Warning sign is on, the exclamation point is not working then air conditioner. When I stop the car, I can't start it again. I showed it to the service, the battery charger says, the battery is dead, I don't understand what it is, brothers. My car 2005 model 307 look package

If the light is on, it is probably a charger. The battery does not light. Once finished, the car will not start.

Some time ago, based on the knowledge of my Cenker master, I tested the dynamo and understood why the light came on suddenly. The battery is independent of that light.

Get the charge dynamo. It is useful to buy a battery after it is constantly charging the battery.

as far as I know the meaning of the light

First of all, thank you guys. Let's not change the battery then I bought the car first on March 18, this incident bored me. Let me tell the master the charger. We had an eagle, he also emptied his battery.

I looked at other forums too, my friends are the same, when there are situations when they are working or not, they changed the starter automatic.

My dad reinforced the battery and started the car

Go to the electrician to find out how many kW the dynamo sends to the battery terminals, and also look at the output of the charger .... Although my dynamometer gave the necessary current, the lights were on because there was a shortage of cables.
