car battery help

You may be able to replace the voltage reg separately or need to replace the whole thing. What car is it?

When I saw this thread title, I put my coat on.......... I thought you needed a push.

2 meters behind when pushing mind, have you got long arms?

Alternator. You're using power from the battery but not replacing it. Your Alternator replaces the power/charge. into the battery.
Surprised our resident auto technican hasnt offered his advice. Can't think what it would be....

Also might be worth checking for a drain on the battery, possible glove box or boot light staying on.

A Renault? Where is Aguerrooo?

alternator has two moving parts the rotor and the brushes, the brushes last for years and are replaceable, the rotor rarely fails ,any problem is audible. A simple check is to switch everything off, disconnect the earth from the battery then gently hold it near the post on the battery, looking for sparks. If you see any then something like a boot-light switch is faulty or a faulty car alarm is causing the drain. Can be hard to pinpoint with the number of components on a modern wiring loom. good luck with that

A Renault with electrical problems....Try replacing the whole car with an alternative brand. That should fix it.

On a serious note - the alternator should be easy to replace. I'd try and get a new one and have a go.
