Low battery warning

So I got the warning the first time and I replaced the regulator inside the alternator (it was missing 1 whole brush), after replacing it upon startup no warning light, but then about 15-20 minutes into the drive the warning light appeared again, I shut the car off and turned it back on and the warning light was gone. It happened like that 3 times before I came home.
Anyone know anything about that? Didn't notice any electrical issues, engine running fine, lights weren't dimming or anything like that.

I have a video I could send somebody if they know anything.
 
Clio 197s/200s are really difficult when trying to replace the original alternator. We replaced the voltage regulator and continued to get the same warning messages. The messages only stopped when we managed to find a second hand OEM alternator on FaceBook.


Read on from this post.

Other people have had a similar problem after replacing the regulator, even though the battery is charging. Some people just put up with the warning messages.
 
These seem to be temperamental when it comes to alternators, specifically using genuine parts. First thing to do is get a voltmeter on the battery and check the voltage with the engine off, then again with engine running. That'll tell you if your fix has worked. I've seen people replace the regulator and the voltages are fine but they still got the battery warning light.
