Folks,
Clarification naman, nalilito na kasi.
PAg magtatanggal ng car battery, anong pole ang dapat maunang tatanggalin? Yung positive ba o yung ground? I've read somewhere na pag nagkamali ka ng tanggal at kabit, either masisira/madaling masira ang ECU/regulator, etc.
Thanks in advance,
[SIZE=2]How do I replace my battery?[/SIZE]
- Visually inspect the battery connections and note the location of the positive (+) and negative (-) terminals.
- Disconnect the negative (-) cable from the battery with a wrench.
- Disconnect the positive (+) cable.
- Remove the hold-down clamp which holds the battery in place.
- Lift out the battery.
- Inspect the battery tray for corrosion or damage. Clean or replace the tray and attaching parts as needed.
- Inspect the battery cables for damage. Clean or replace the cables as needed to ensure a good connection.
- Install your new Interstate battery and secure it with the hold-down. Be sure the new battery is the same voltage and group size as your original equipment battery. Check to ensure that it has at least the same cold-cranking amp (CCA) and reserve capacity (RC) ratings as specified by the original equipment manufacturer.
- Attach the positive (+) cable to the positive (+) terminal.
- Attach the negative (-) cable to the negative (-) terminal. Be careful not to over tighten.
Thanks for the clarification.
ako, ewan ko ba, sop ko negative.....
pero kotse ko, sa maxima positive kasi, naka quick-release yun,e....otherwise, negative (aka ground)
alam ko masama lang sa ecu ang over current.....
AFAIK, always negative muna for removal then una positive kung babalik na.
diko lang sure kung me effect ba yon kung alin ang mauuna pero ako laging una ang positive..alang pinagkaiba sa high voltage yan (electrical, lalo na sa line to ground) dapat unahin mo yong hot wire para dika matusta :belat:
The reason? See this:Quote:

The positive cable when unhooked from a battery almost always causes a small spark which is harmful to electronic circuit boards present on almost all cars nowadays. Unhooking the negative cable first prevents static sparking and "leaking" voltage from escaping the circuit.
For the same reason, when using jumper cables, connect the negative of the dead battery last.
Nothing happens to the vehicle if you connect the negative side first. But is is safer to connect the positive side first.
Reason: If the negative side is already connected and you put the positive side on you take a chance of touching a part of the body or radiator with your wrench while tightening it, causing the positive side to ground out.
If your negative side is not connected yet and you touch the wrench to the body while tightening the positive side nothing will happen.
So installing the positive side first reduces the chance of shorting the battery out which could cause the battery to explode.
either one of the two :)
If either one is cut off, the circuit is definitely cut off...no surprises :)
But usually if you have a quick release pole clamp it is connected in the positive terminal.
Just my opinion lang :)
ahh.. yun pala reason. well tinuro lang sakin yun ng erpats ko yung bata pa ko kaya yun na nakasanayan ko. thanks for the info. :happy:Quote:

A full charge battery has very high output current, so be very careful not to create a short circuit between the Plus and Minus poles while servicng the battery. If that happens, you will end up with either a melted/ burnt out metal tool, or it can produce strong electrical sparks which can lead to a fire.
not to mention getting quite a shock :electricf:Quote:

Thanks for the info
laking tulong nito sa mga newbie sa car.
sa trabaho noon ay may nagtanggal ng battery sa loader at di nya alam na ang kabuunan ng metal body nun ay NEGATIVE.
ng magtanggal sya, positive muna ang inuna kaya nung simagi ang wrench nya sa metal body ng loader ay sumabog ang isa sa batties at lumipad ang pole (lead) at tumama sa mata nya kawawa naman.
kaya ako pagnagtanggal ng battery ko negative muna at sa pagbalik ay positive naman ang inuuna ko.
Ang sa akin lang syiempre ang nakaground mauuna dahil pag yung isa ang tinanggal mo may positibo na kumpleto ang current pag nadikit ang katwan mo sa ground o ang tools na gamit mo may spark na mangyayari o gulat na maaaring makasakit sa katawan o sa katabi mo, maliban na lang kung may quick release ang kanilang mga terminal.
+ 1. this is really for safety purposes.:nod:Quote:
