If you take it to a place that sell batters they should be able to test the batter and charging steam for you if not you can buy a tester of your own. If battery and charging system is ok then many places will sale you a grease or pad that will help stop corrosion on terminals.

SOURCE: alternator charges at 14.4volts, replaced regulator, same result. boils battery.

The max charge voltage is usually around 14.5 volts, so 14.4 is not high.
Its possible the battery has a dead cell and that is causing the acid problem.
You might want to check with the dealer on what the max voltage is for your car.

SOURCE: my terminals are bad and i cant find the right

Your local Mercury or Ford dealer will have those battery cables. Obviously will cost a few bucks, but they will be the right size.
Or you can go to a local parts store where you can buy battery cable per foot, right diameter (called wire gauge size-- take your old cables for matching) and length.
Then you will have to buy the terminal ends which you can either crimp or solder the battery cable to.
Also you will be needing different battery terminal posts to hook up the battery cables to the battery.
Good Luck.

SOURCE: positive terminal keeps getting corroded even after 3 weeks.

Try keeping the terminal far away from any moisture and dirt. In fact isolating it may not be a bad idea. Try getting a battery box for it or sealing off the existing one, just make sure to use a drain tube and vent. Some stores have battery terminal isolators, these are less effective but can help. There is also a battery terminal sealant spray that may be helpful if you cannot get/use a battery box. Clean the terminals thoroughly, spray the terminal sealant, and use the battery box for a three way attack. This is especially use full in harsh climates. These methods can also be used on remote battery terminals that are on some cars.

SOURCE: Cleaning Battery Terminal?

Using a suitable container place a heaped tablespoon of common cooking 'bi-carbonate of soda' - add approx 4 cups of hot water .
Dip the battery terminals / battery clamps in and wait for the fizzing to stop.
This will neutralise and disolve the acidic deposits.
Wash off with clean water, then paint any exposed metal parts of the battery clamps with acid resistant paint.
Apply thin coating of vaseline to assembled battery terminals to resist future corrosion.

Most likely not a battery problem. Since the battery is fairly new, a good charge should restore it. As far as the corrosion, A thorough cleaning of the battery cables should suffice and replacement shouldn't be necessary.

What's your question? hi if the wire leading to the positive terminal of the battery gets corroded by battery acid can it effect the car in starting. ....

Most certainly. If battery acid is present on top of the battery, the seal between the post and the top of the battery is leaking. Replace your battery and use baking soda and water to clean the battery cable.

Can be several things: Loose terminal connections to solenoid, corroded terminals or wires, bad solenoid with burned coil or pitted contacts. Lastly, a too worn out key switch. To find out, test proper (12VDC) voltage at solenoid coil terminal, check for a bad ground too. Then test wiring between key switch and starter. Some power feeds are fed from fusible link harness behind battery box. For the age of the car, there could be some corrosion on terminals or even corroded and broken fusible wires because of nearness of battery acid vapors tend to eat near wiring slowly. My two cents.

What is the white powdery stuff on my battery post/terminal and is it affecting my new battery? If so, what do I do to fix/remove the issue?

It should never be there
It has a big effect on your battery & could cause it
to drain down
That is acid leaking out & should not be

You remove the battery & wash it with baking soda
dry it & clean the acid off the cables.

If it continues your battery is either bad or the alternator
is overcharging
I suspect the battery was not a good brand or choice on your part,
they should not leak

My car want start battery is fully charged. But the immobilizer light on the instrument panel stays on?

Having a full charged battery won't just solve the promblem. You might want to check with the battery terminal connection on the postive+ and negative-, It might be corroded, grease, or acid build up, so check for thse signs, also it could be that clamps are not fully tighten. You still can get power to the car from the baterry which in this case is leads to the immoblizer lights on the dash boards to stay on, but the terminal are corroded with acid, grease, or just from dirt, and with these element in presence, the battery is not fully ground. The engine needs a specific amount of amplitude from the battery for the engine to crank. A kia sorento v6 engine needs alot of cranking amp. So my solution is, check the battery connection terminal on the battery and the cable (positive and negative connections) de-tach the cable connections, clean the connection cables which are the adapter to the battery, and the battery terminals, with a toothbrush or high grit sandpaper until dirt, acid build up, grease are gone, and reinstall the cables. See if this will help.

1.Loose Battery cable. Very common thing for a side post battery.

Solution: Tighten both battery clamps as needed.

2.Corroded connections for battery cable ends. The cable ends that connect to the battery.

(A side post battery was a bad idea IMHO.

When a battery is made the posts come up through a plastic case. There is a seal around the post, under the plastic case that you cannot see.
This seal allows battery acid to eventually leak out.

It was bad enough for a Top post battery, but seems like a ridiculous idea placing the posts on the side!
The idea was implemented to save space, so that cars could be made smaller)

Solution: Clean battery clamps, and side post area on battery.


Hand Protection:
Gloves should be worn when working with a Battery.
Dishwashing gloves would work, but be sure to replace them, if a hole is torn while you're working.

Thin leather gloves are preferred.

Use old clothes that you do not care about, and may be thrown away if needed.

Eye Protection:
Safety glasses, or goggles should be worn. If safety glasses are not available, at least wear some sort of eye protection.

As said, battery acid does leak out. Usually a tiny amount, and not always seen. Even if dried, it is still potent.

This is Sulfuric Acid.

It will eat holes in your clothes. You won't notice it until you go to wash your clothes.
It will burn your skin, and eyes. DO NOT touch your face until the gloves are removed, and you have thoroughly washed your hands.

Use cold water first. Warm water will open the pores of your skin.
After using cold water, and thoroughly cleaning your hands, then you can use warm water.

When disconnecting a Battery, ALWAYS disconnect the Negative terminal first! Positive terminal last.

When connecting, Positive terminal First, Negative terminal last.

You can use a solution of Baking Soda, and water to clean the battery clamps.
Two tablespoons of Baking Soda to a 12 ounce glass of warm water thoroughly mixed. (It won't mix all the way. Squish it around in the glass as you are using it)

You Cannot use this mixture on the Battery. There is a chance it could go through the seal/s, and will nullify the battery acid inside, ruining the battery.

A wire brush is used for this application. (One of the reasons the eye protection is imperative. The wire brush bristles could sling dried battery acid up in your eyes)

3.Bad battery:
Could be the battery is at, or near the end of it's 'Lifetime'.

4.Bad Alternator:
The alternator isn't working, therefore isn't charging the battery.

5.Loose or Worn Alternator belt:
The belt/s are worn allowing the belt to slip on the Alternator pulley.

Have battery but engine wont turn over

1.Do the headlights come on? Are they as bright as they should be? No? Check the battery cables, and connections. A corroded battery cable terminal end, and battery terminal will cause this. (Even side post batteries have a terminal. It's just a flat area with a threaded hole) Side post batteries are notorious for acid leaking out of the side post area, and corroding the connections. (I change everyone of my vehicles to use a Top Post battery)

2.Battery terminals and battery terminal ends clean? Battery cables good? Then it's the starter solenoid, or the starter itself.

Inside the starter solenoid, (Mounted to the starter. It's that cylindrical looking object on top of the starter), are contacts. These can burn, and wear out over time.

Inside the starter are brushes. The starter is just an electrical motor. The brushes wear down over time, and do not make contact anymore.

If somehow this is the original starter, and starter solenoid, consider yourself LUCKY! It has seen it's use, and is well past time to be changed.

Moved + bat terminal, now dashboard dials don't work

For safety purposes always always remove the negative side first. This eliminates the possibility of shorting out your wrench against the body or any other negative charged part. There is strong possibility of shorting out the battery which could blow up. This happened to my brother as a kid and he ended up with battery acid in his eyes.
Try unhooking the negative side of the battery as this may reset any relays.
