battery or alternator problem??

[joseph20]

mga sir, while im driving, nakaka experience me ng loss of power at parang nag chochoke na. So, stop me sa shell, den pinatay ko muna, nung start ko na, yaw na nya mag start, sabi ng mechanic dun, baka daw battery or alternator, but they are not sure. Pinacharge ko battery, so aun, umandar bigla. Nakauwi nmn me kaso wala aircon. Dinala ko sa electrician ko, then tinest nya battery ko, gulat ako, 14 pa no aircon, then 13.5 nung may aircon na. So, malakas pa, sabi nya, palitin na raw battery kasi baka raw panget na plate ng battery, at hindi daw alternator kasi malakas pa daw mag charge. Tanong ko po, battery na nga kaya sa tingin nyo? Bakit biglang lumakas ulit yung battery ehh, saglit lang naman po siya na charge.Thanks

The question is how old is the battery?

Your alternator is good as the mechanic said. Perhaps your battery can no longer hold when the battery becomes discharged, it will cause a small about of water to evaporate. Remember that the battery is filled with diluted acid. Over time, the water level drops to such a level that it won't hold a charge.

Maybe this not your case, could it been your battery cable was loose, dirty during that time when you were driving and all the juice that you need are run out, causing your car chocking and wont start anymore.

A good question is when was the last time you changed your battery?
When a battery is charged lalakas talaga but pagmalapit na masira, storing capacity of the battery deminish meaning maski full to hilt ang karga mamaya wala na. From experience once you let your battery cooldown it recovers and be able to crank or start better.

since okey naman ang charging during testing, try mo ang CRANKING TEST,para malaman kung battery ang sira .

mag 2 years na pala batt. ko. Dyna Power Brand. Try ko rin yung trick na tanggalin ko yung positive terminal sa battery, result is hindi naman namatay makina. Sabi ng mechanic, hindi na raw kasi maganda plate ng battery. Pero, sabi ko nga bakit lakas pa nya, nasa 14 pa meter nya. 2 New Battery Terminals naman. Time na po kaya na palit na battery?? hindi nama po siguro alternator, kasi lakas pa naman mag charge daw!

If ever you decide to replace you battery, get a good brand.

More than likely, papalitan na yan. If you want to be sure, ipa-load test mo.
