in August, my battery was dying. So i went to claim warranty. It lasted only 3 months
Now December, it shows dying again.

fyi, i drive 300km everyday non stop. All interior light change to white color, I charge my phone twice per day under QC3.0, recently put a dashcam and 6 seat underleg LED light.
How to diagnose the alternator?

add: one more thing is my headlamp bulb always burn every month. the RM20 bosch osram, chapalang one burn 1 day also got 1 week also got.

If not alternator problem, most likely it's those wiring done by unprofessional accessories shop people...

All never go to school workers.... some cannot even differentiate positive and negative. The boss sometimes also same.

Headlamp u also upgraded ? Previously halogen, and u install HID or LED ?
Then another area you seriously need to suspect how they do the wiring.

Must be wiring problem.

The best way, Use the voltmeter to check if your alternator is charging or not. Not sure the value while charging. You can check at youtube.

Another way is to use steel wrench and put it near the alternator while running/charging. If your alternator is ok, you can feel the wrench stick to it. If your alternator not ok, the wrench will not stick. Btw, it's not recommended to use this method.

Sound like malfunction alternator voltage regulator problem. Everyday 300km frying battery to death. Check engine running with no load what is the voltage? If more than 15v voltage regulator Kong already.

I suspect due to alternator voltage regulator problem.

Did you touch any wiring when modding? Check the voltage when the car is running, especially when you are driving for long. Anything 14.8V and above then you'll have an issue especially expose to such high voltage for such a long time.

You never mentioned if you installed any after market parts in it, like voltage stabilizers, earth cable, aftermarket head unit, HID, extra spot lamps, interior lamps, 3rd party alarm, GPS, OBD II display, blah blah.

I can only say wiring problem done by one self. No one behind the screen can tell you how to solve if you did any of those.

Disconnect the led underleg light. If those led not properly ground or poor designed circuit, you will get some leakage into ground connection.

Undo all your wiring mods, charge up the battery and observe.

Get a battery tester and start hooking back one mod by one mod, each one use a few days, observe and confirm no leakage then add the next mod.

This way you can pin point better where the leakage is coming from.

Alternatively, buy a battery charger like Bosch C7 or Ctek (more exp) and charge your battery every 2-3 weeks.
