car battery/voltage meter

**enu** · August 13th, 2013 02:38 PM

mga bossings,

ask ko po sa inyo kung meron na sa inyo naka-try ng car voltage meter?

Qoo10-Singapore - Automotive - ?Car LED Battery Tester? Using Cigarett...

di ko po kasi alam kng paano ma-check kung ok pa yung battery.
naiwan ko yung headlight ko na nakabukas ng maghapon.
kaya natatakot ako at baka bigla na lng tumirik ako sa daan.

plano ko po magpabili ng car voltage meter...yun nga lang di ko sure kung advisable or reliable ba sya.
hehehe.

thanks!

basta ma charge ng alternator batt mo it should be no problem na.

old cars had voltmeter and ammeters. to make the car's instrumentation simpler. manufacturers replaced them with idiot lights or charge malfunction indicator light. of course the predictables (voltage is regulated when the engine is running and the alternator is working satisfactorily) don't need elaborate gauges. similar to aircraft instrumentation. the flight crew, the pilot, co pilot, navigator and flight engineer tend to panic if one gauge is fluctuating or some warning lights flicker. but with this similar scenario, on military aircraft, should it happen while forward deployed in a hostile area, the crew will try to fly it back home. if the malfunction happens in say for example hawaii, puerto rico or japan or europe, the flight crew will use this as an excuse to stay at club med for a considerable time. the warning lights should suffice as long as you do your routine preventive maintenance.

unless you want it to look like this

maganda sha as an accessory pero other than to monitor battery life parang hindi sha worth it.

punta ka na lang sa car battery store, normally free service naman un pag check ng battery status, pwede ka pa mag second opinion sa ibang shops.

hindi mo rin ma chcheck yan diba? kasi when car is running ung alternator na nagsusupply ng voltage hindi na galing sa baterya.

in my opinion... no.
baka mas matakot ka lang dahil ma-worry-worry ka sa mga numerong makikita mo diyan.
i had one 20 years ago.. never got the chance to appreciate it. never missed it at all.

If you remember. Naka parallel connection ang Alternator sa Battery. Then ang DC Voltmeter ay parallel connection din sa Battery. So any voltage reading ng Alternator at Battery ay ma monitor ng DC Voltmeter.

During high rpm ay ang alternator ang mag supply ng dc voltage sa kotse while charging the battery. Pero during low rpm ay mahina ang charging ng alternator at yun charge ng Battery ang additional supply para sa electrical ng kotse..

correct sir. ang point ko lang naman you could get an accurate reading of the battery voltage pag patay ang makina kasi pag naka engine on, ung reading ng alternator ang ma re-read mo instead of the battery. kung baga hindi accurate kung battery lang gi read mo.

Useful yan voltmeter na yan to monitor yung charging lalo na kung full load at naka idle yung sasakyan. Alam mo na kung di kaya icharge so me option ka na mag off ka ng iba pang naka on sa auto mo.

I used this before. Dami nagkalat sa banawe acc shops, even blade/concorde.

Helpfull in a bit. Me threads na rin dito about car batts.

Afaik, below 11.9v cannot start the engine na. While idle or rev a bit voltage will play bet 13-14v.

Yun iba naman, 'upgrade' to reduction type starter which can still start your car at 6v ata (not sure sa min voltage requirement)

By experience sa motolite, usually starts to fail on 25th to 26th month nya (past the 24mo warranty). Charge/power doesn't stay long na.

Kun manual ka, no need to worry at pwede itulak (in case no issue with electricals when batt fails o discharged).
