Have brand new battery on car and it looks corroding

Just put a new battery in the car three months ago. It was last driven a week ago. Went out to start it and it was dead. Checked the battery and the connections look corroded. What could be causing this?

SOURCE: windshield wiper solution stained the hood of my car!

Yes. Go to any auto parts store and get a rubbing compound especially for autos. They may even have one especially for your color. This stuff works great.

I had the same problem with a Tercel, it was the distributor cap had a non-visible hairline crack in it and allowed moisture in.... does it do this only when it rains or high humidity?

SOURCE: Corroded battery cable?

To do a good job if you havent already done it is to tip hot water over the battery term and it will dry clean ,,if corroded term then replace it but you dont have to buy with a new lead ,,only a positive term only and then hot water over the battery lug when new term on then spray with Hair spray .
If battery cable dident corrod with other battery then your battery is either charging more than 13.5 volts and or battery post to battery is cracked
Wash and spray then check first

When the bushes in a starter get worn, it can cause the armature to rub on the magnetic poles (poleing) This can cause the starter turn slow or not at all
The sintered metal bushes are like bearings. Not to be confused with carbon brushes which are the electrical connectors.
When a starter clicks, it is the solenoid you can hear.supplying power through the brushes.

A starter that is poleing,often stops in a place where it isnt rubbing, and works fine the next start.
There can be other problems with a starter , perhaps one of the brushes is sticking, or the solenoid.
When it happens a tap with a hammer on the starter or solenoid, while a friend turns the key, is enough to get it working( this isnt a fix but might get you started in an emergency)

There is also the possibility of a loose or dirty cable connection, from when the new battery was installed

Have something draining my car battery. I have a 1999 Pontiac Bonneville, and I have to get a new battery about every 18 months. I had a new alternator put in, new not used, about 20 months ago. I replaced...


If you have a drain on your battery , it would not take 18 months for the battery to go dead . What do you mean The battery gauge in the dash shows only about 1/2 power, When ? When the vehicle is running ? Not charging ! The battery gauge as you call it has nothing to do with the Battery . That's showing how much the charging system is putting .The volt's indicator is controlled by the PCM - engine computer . With the engine running should show 14.1 volts .if your only seeing 7 the charging system isn't working. The alternator is controlled by the PCM as well ! Have it check by a GM dealer .

What is draining my car battery?


sounds like perhaps it is time to purchase a newer car and let that one find a new home . our daughter had a problem like this and after much expense was told to unhook every thing electrical she could . ended up being the radio/stereo in the trunk.

On a car that old, I would suspect a corroded fusible
link, in the wiring harness

I don't have have referrence material to help you
locate those items.

You still have to start buy checking the battery & it's cables
No power to anything at all,your working your way from
the battery to fusible links & on to fuses,to see what you do have

Really need a wiring diagram,if your into that type of understanding
of electrical

Are these factory OEM replacements? I once put three cheap aftermarket Kragen batteries in my Corvette in 6 months, bought a Delco and problem solved, that was years ago. Sounds like your problem is that the car sits to much, if it sits more a few weeks either hook up a float battery charger or disconnect the negative cable to the batt.

1999 blazer wont start??


Your battery is either faulty or ther is a parasitic drain, have it checked out at parts house. With a good battery installed, spray some starter fluid into intake housing. If it starts, then dies, you have fuel pressure/delivery problems. Can you hear the fuel pump run when you turn on the key? Hope this helps.
