what is the right gauge for battery?

[rollyic]

yung car ko pong nissan series 3 ay may almost 2 yrs. nang motolite enduro 2SM maintenance free na battery.

nung pina check ko sa isang battery dealer, sabi nya ok pa naman daw yung battery ko at baka umabot pa ng another 1 yr. pa ang buhay.
ang problema daw is yung alternator ko. hindi daw nagka karga kasi 12-13 lang daw yung reading. dapat daw nasa 14.
ni-recommend nya kong ipa check sa isang auto electrician malapit sa tinadahan nila.
sabi ng auto electrician, di nga daw kumakarga. dapat daw talaga nasa 14 ang palo.

medyo duda ako sa sinabi ng auto electrician, kaya pina check ko sa dalawang auto electrician na nadaanan ko along the way. sabi ng dalawa, ok lang naman daw ang karga ng alternator ko. dahil sasabog daw ang battery kung nasa 14 ang reading.

ano po ba ang tamang reading?

charging systems are designed to put out 13.5 to 14.5 and on some toyotas, the output is up to 15 volts. it depends on your make and design. the most common ones are between 13.5-14.5 volts. check your battery output by disabling the fuel delivery and cranking for 15 seconds while observing your battery terminal voltage. while doing this, the voltage should not drop below 10.5 volts. your pcm and other computers only operate with a minimum of 10 volts regardless you are cranking, cruising or decelerating. once the voltage drops below threshold, engine operation ceases

^^mine's charging at 14.2 Volts at idle no load....goes down to 13.8 V at full load (A/C, Radio, all lights including hazard)......75A 12 V alternator.

so meaning, talagang sira yung alternator ko?

don't be so easy to condemn your alternator! check your belt for tension and condition first. then check your battery. remember: the alternator DOES NOT work without a battery. it is the battery that supplies the field coil to make it a moving electromagnet. then check your terminal for cleanliness and tightness

bago po yung belt...kapapalit ko pa lang po.

for any lead acid battery the normal minimum voltage for charging is 2.3volts and maximum is 2.6 volts PER CELL. since there are 6 cells in a 12-volt battery then minimum is 2.3 x 6 = 13.8 volts and the maximum is 2.6 x 6 = 15.6 volts. that means that for a charging system to work it has to have a voltage of between 13.8 - 15.6 volts. so tama sila na sira na alternator mo kasi mas mababa na sa normal minimum charging voltage.

note i said normal minimum charging voltage. that is because may tinatawag na "trickle charge" or "float charge" which is just at 13.4 volts. this is for systems that are on stand-by, like on UPS systems.

mukhang sira na nga yung alternator ko...
kasi binuksan lahat, aircon, headlight, car stereo pati hazard...pumalo lang sya sa 12v.

kaso sabi ng 2 technician, normal lang daw sa 12v. kasi ginamitan nila ng isang klaseng gauge na nasa gitna lang ang palo.
pag under daw or di nagcha-charge, nasa kaliwa daw dapat ang palo ng gauge. saka di naman namamatay ang makina pag tinatanggal nila yung battey terminal.

ano po sa tingin nyo? sira naba talaga ang alternator ko? o dahil bagong palit ang belt at masikip pa kaya medyo hirap ang alternator?
