Usually, battery terminal corrosion occurs when the factory seal between the battery case and the lead terminal has failed, allowing some electrolyte [battery acid] to work its way through to the outside.
It tends to "wick" upward [due to surface tension] on the terminal post, and eventually to the cable clamp also.
Although lead in the battery terminal is relatively inert, the Sulphuric Acid does cause some corrosion.
The fact that this is happening only at one terminal suggests the the seal at the other terminal is still intact. This is unusual in that eventually almost all batteries leak slightly and cause terminal corrosion.
The only "fix" is to remove the cable clamps, clean the terminals and clamps well, apply some grease around the base of the terminal post and on the non-contact area of the cable clamp, then reinstall, and coat the entire assembly with grease. This will tend to inhibit the ability of the acid and its vapors from contact with the interface of the terminal post and battery cable clamp, an hopefully extend the time period before it becomes necessary to clean the posts and clamps again.
For years, it has been recommended that the terminal posts and cable clamps be thoroughly cleaned AT LEAST once a year, and anytime corrosion is observed.
What else can I help you with?
Should you disconnect both battery poles of a car if you will not use it for 7 months or is disconnecting only one pole enough?
NO....you only need to disconect one terminal to stop circuit continuity. If you take 2 terminals off cover them with greese to stop corrosion.
How do I hook tWO six volt batteries together to get 12volts?
Connect them in series. With the 2 batteries sitting side by side just connect the negative terminal (-) on battery # 1 to the positive terminal (+) of battery # 2. Now connect the red hot cable to the positive terminal of battery # 1. Then connect the negative black cable to battery #2. You will have 12 volts but the amperage of only 1 battery.
Under what circumstances can the terminal potential difference of a battery exceed its emf?
"The potential difference between the terminals of a battery will equal the emf of the battery when there is no current in the battery. At this time, the current though, and hence the potential drop across the internal resistance is zero. This only happens when there is no load placed on the battery-that includes measuring the potential difference with a voltmeter! The terminal voltage will exceed the emf of the battery when current is driven backward through the battery, in at its positive terminal and out at its negative terminal."

What are semiconductor devices allowing electricity to flow only one direction from the negative to the positive terminal?
battery
Where is the battery on a 2000 2.7 intrepid you only see neg terminal?
The battery is on the passenger side of the vehicle, behind a barrier in front of the wheel. You have to remove the wheel and barrier to access the battery.
What type of current will a circuit that involves a battery and electrons traveling in one direction have?
a battery always produces a direct current.the electrons always travel from the negetiove to the positive terminal.But the direction of the current is the opposite that is from the positive to the negetive terminal.
Why would a 1998 bonnneville not start the battery is new the starter is only a year old?
there may be a ground wire from the negative battery terminal that isn't making a connection
How do you use a single terminal car horn on a two terminal electrical wiring system?
On a vehicle, the return path to the battery is through the vehicle's framework. The negative terminal of the battery is connected to the frame of the vehicle. The reason there is only one terminal on the horn is that, that is all that is needed to make the horn operate. Applying the positive side of the battery to the single terminal which is connected to the horn's coil will make it operate. When the horn is bolted to the vehicle this completes the circuit back to the negative terminal of the battery. Apply the 12VDC to the horn by pressing on the horn button which closes the circuit and the horn activates. A horn with only one terminal has its coil grounded internally within the horn. A horn with two terminals has the coil isolated from the ground. On a two terminal horn there needs to be a wire installed to the frame on one of the terminals to make the horn operate.
How do you replace battery 2006 grand prix gxp?
Oh, dude, replacing the battery in a 2006 Grand Prix GXP is like, super easy. You just gotta locate the battery under the hood, disconnect the negative terminal first, then the positive terminal, swap out the old battery for a new one, reconnect the positive terminal, and then the negative terminal. Boom, you're good to go! Just remember, positive vibes only when working on cars, man.
When you turn the key to start your car it turns without starting?
dead battery or corrosion on eletrical connections wet wireing in motor bay if no response corrosion may be problem even if only small amount of corrosion can abstruct normal eletrical functions
Will a corroded battery cause your car not to start sometimes?
YES!!! Replace the car battery. The white corrosion seen on one of the battery terminals, is also inside the battery. The internals of a car battery contains lead plates , copper platres and sulphuric acid. During the (dis)charging process the sulphuric acid combines with the lead to form lead sulphate (The white corrosion). When sufficient of the white corrosion builds up inside the battery on the lead plate , it will eventually touch to copper plate. Whereupon the battery discharges and will not re-charge. The battery is //??@@#@!!! XX . So replace the battery. Sometimes, during the sulphuric acid /lead reaction hydrogen gas is liberated, if an electric spark occurs in the gas , there will be an explosion. So definitely change the battery!!!!!
Which terminal of the VW Golf battery is grounded is it the positive or the negative terminal?
grounding is always neg on a 12 volt american car. I only know bulldozers that reverse it. hope that helps you out.
