A grease-like material that keeps H20 from soaking into your battery!
People usually use petroleum jelly rather than grease because it does not harden with time. It prevents water coming into contact with the different metal components preventing electrolysis which, in time, will degrade the terminal and allow the build up of salts preventing a decent connection.
It is smeared over the terminal of the battery and the connector before they are brought together - this helps ensure that there are no metal parts exposed to the moisture in the air...

Can grease be used to prevent corrosion on a car battery terminal battery?
A very thin smear of Copper Grease over the Battery terminal / Cable end will help pevent corrosion.

How do you connect a 24 volt charger to two 12 volt batteries?
You connect the batteries in series Red charger lead to one red battery terminal, then the black battery terminal of that battery to the red battery terminal of the second battery. Then black battery terminal of the second battery to the black lead of the charger.
What causes car battery corrosion on only one terminal?
Corrosion at Battery TerminalsUsually, 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.
How do you change starter on ranger 2002?
Jack and support front or use ramps to elevate front of vehicle. Disconnect the negative battery terminal. Remove electrical connections and then the mounting bolts, be careful, the starter is very heavy. Align and install mounting bolts, then reconnect electrical connectors, and reinstall negative battery cable. It might be a good time to disconnect the positive battery terminal as well, use a terminal cleaner to clean the battery terminals, the insides of the clamps, then spread dielectric grease over terminal, reconnect all and snug.
What is the end of a battery called?
The top of a battery is called a carbon rod, which is on the positive terminal.
Replace battery 2004 Dodge Durango?
REMOVAL Turn the ignition switch to the Off position. Be certain that all electrical accessories are turned off. Loosen the battery negative cable terminal clamp pinch-bolt hex nut. Disconnect the battery negative cable terminal clamp from the battery negative terminal post. If necessary, use a battery terminal puller (2) to remove the terminal clamp from the battery post. Loosen the battery positive cable terminal clamp pinch-bolt hex nut. Disconnect the battery positive cable terminal clamp from the battery positive terminal post. If necessary, use a battery terminal puller (2) to remove the terminal clamp from the battery post. Remove the battery cables from the battery. Remove the battery thermal guard (1). Remove the battery hold down bolt (1) and battery hold down (2) from the battery. WARNING: Wear a suitable pair of rubber gloves (not the household type) when removing a battery by hand. Safety glasses should also be worn. If the battery is cracked or leaking, the electrolyte can burn the skin and eyes. Remove the battery from the battery tray.
