A very thin smear of Copper Grease over the Battery terminal / Cable end will help pevent corrosion.
To clean a corroded car battery, first ensure the vehicle is turned off and disconnect the negative terminal followed by the positive terminal. Use a mixture of baking soda and water to neutralize the corrosion; apply it with a brush to the terminals and cable ends. Rinse with water and dry thoroughly, then reconnect the terminals, starting with the positive terminal first. Finally, consider applying a battery terminal protector or grease to prevent future corrosion.
It could start but if it is indeed corrosion you probably want to clean it off. Somtimes people will lightly apply a form of anti-corrosion grease to battery terminals to prevent corrosion. Your typical signs of battery corrosion look like greenish or white stuff that will crumble away easily when disturbed. You probably don't want to touch it though a bottle of water and some old rags (where some protective gloves and/or wash hands thouroghly afterwards) that you can throw away, should clean it up. The battery terminal affected should be removed and cleaned to a shine with a wire brush for best results. Be careful working around battery terminals as not to short the battery it could be very dangerous. But yes battery corrosion will definitly cause a car to not start. I don't recall seeing it look like grease, that is unusual. Hope this info helps.
Battery corrosion can be prevented by covering terminals with grease or installing washers under the terminals
No you do not need to use bulb grease but for 89 cents at your local auto shop its good to use it just like battery terminal grease its good to use projects your connection from corrosion
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.
There is a product that looks like flat washers made of felt that you can fit over the battery posts that will prevent corrosion (don't remember what it's called, but available at your local auto aprts store or Walmart). You can also try putting a dab of grease on the battery posts and terminals after cleaning. The grease will work best for you to help eliminate corrosion's. The point of putting grease on the terminals is to keep oxygen from coming in contact with the terminals and also help with keeping acid off the posts. When you clean the terminals use baking soda and water to neutralize the acid which will help for future corrosion
Its a cheap way to prevent water from soaking your battery and also prevents corrosion on the terminals.
Best is a wire brush and baking soda. You can use grease to coat the terminals to slow down the corrosion.
If the terminal to battery connection is loose snug up the center bolt (not too tight or you will pull the retaining nut out of the battery). If you have a molded, once piece cable you can buy new battery cables or side mount terminals at your local auto parts store. If your cable can be disassembled then take it apart, clean off all corrosion and trim/strip the cable and connected wires so you have good clean metal to work with. Reassemble and use battery terminal protector spray or grease to help prevent future problems.
The best type of grease to use on a garage door track is a silicone-based lubricant. Silicone lubricants provide smooth operation, prevent rust and corrosion, and are long-lasting.
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...
Personally I have used Vasaline petroleum jelly on my battery cable connections for many years with no problems
