Strange case: Battery won't hold charge

[zap.FREEDOM]

Try mo check yung battery clamps. Malamang maluwag na kaya hindi nagchacharge ng maayos. Happened to my beloved Lancer.

ito rin po isang suspetsa ko e, kasi dun po sa negative terminal post, may mga white deposits na namumuo tapos po sa positve terminal naman, may kalawang na po dun sa clamp, try ko po sa thursday mapalitan, medyo busy ako ngayon e.

If the battery discharges while engine is running, then the alternator current is not enough to supply to the electrical loads. Check the voltage while engine is running on idle with all usual electrical loads on (head lights, stereo, aircon, etc.). The voltage should not go lower than 12V.

To check if the alternator is charging the battery:
- start the engine
- disconnect either the negative or positive battery terminal
If the engine dies..the alternator is not charging

Good luck with your in-car electronics sa ganyang method...

baka pumutok ang fuse.

for probably lack of tools/equipment and understanding your car's problem, you can try to isolate the battery by disconnecting the negative terminal when you park for the night and check if the battery is still charged in the morning. this will differentiate excessive parasitic load from a bad battery. if your battery does not have a hold down, chances are the battery is partially shorted by the flakes of lead compounds that fell off to the bottom of the battery shorting out the positive and negative plates.

case closed: just got replaced my battery terminals at tinabasan ko yung positve and negative cable then put a new eyelet terminal then clean the fuse box, ayun naka-biyahe na ako ng malayo-layo kanina, there's no discharge happened saka chineck ko rin, wala ng white deposit na namumuo dun sa post ng battery ko, dati after use may namumuo e, ngayon wala na.

okay, case closed. dismiss na.
