Always keep the battery terminals clean. Simply wipe them with a mixture of baking soda and water then scrub clean with a wire brush.
It's also important to know that if the battery is severely overcharged or the ventilation is inadequate or the battery itself is faulty, a flammable concentration of hydrogen can remain in the cell or battery enclosure.
Make sure that the battery cables are tied tightly enough so that they do not move around.
your battery should be kept safely in a tray so that there is minimal damage to the hood.
the power will be drained if the cabin lights are left on for a long period of time also using the air-conditioner when the engine is in idle. Factory defects can also cause issues with the ability of the battery to maintain charge.
Proper safety is important when working with your battery. Make sure there are no open flames around the battery while checking it.
Check all thick gauge cables from the battery to ground, solenoid and starter for tightness. If you find corrosion (it's caused by leaking battery acid) on battery terminals, remove cables and clean battery posts and clamps thoroughly with a wire brush and then scrub with a mixture of 25% baking soda / 75% water on an old toothbrush dipped in the mixture. Continue adding & scrubbing with mixture until fizzing stops. When fizzing stops, the acid has been removed. Next, wash down the whole top of the battery with the mixture and hose off when fizzing stops. Keep any caps secured to the battery! Do not let baking soda mixture enter the battery. You may need to charge or jump the car to get it started again - but the battery should accept a charge for the alternator at this point and keep from draining (assuming the battery is still good).
Are you sure you need to replace the entire cable or just replace the terminals that the cable is connected to?The terminals may be worn out and loose which leads to corrosion. Simply go to an auto parts store and buy the appropriate terminals and replace them. You can also get a wire brush to clean the cables before installing the new terminals. Also there are some corrosion protectors that help aid in corrosion.
Fist thing to try for a quick fix would be to clean terminal posts. It's a pretty easy do-it yourself project.
To do this find where your battery is connected, remove the negative battery cable (black with a - sign) then remove the positive terminal ( red with a + sign). Clean both the terminals and cable end with a wire brush. If heavily corroded, use a paste of water and baking soda on a toothbrush to scrub then rinse off. This may bubble and foam when it comes in contact with the corrosion. After you've rinsed off any remaining baking soda, replace the positive terminal first and tighten, then replace the negative terminal and tighten.
If that doesn't solve the problem, I'd have the alternator tested and replace if necessary.
Hello
Sound like a bad connection or dirty battery cable ends.You will need to clean the battery terminals.
Take a wire brush or some emery cloth or even steel wool,remove cables from battery using a pair of pliers or if you have wrenches use them.If there is any white or green corrosion get it off with the tools listed above.Claen battery cable ends also.
Once you have everything clean wipe off the top of the battery with a damp rag,i prefer to use a mixture of water and baking soda.1 gal of water and 4 spoons of baking soda,shake it up and dump it on the battery.
Then dump a gallon of pure water to neutralize any acid,remember to wear gloves and eye protection.
You need to replace the terminals on the battery leads and clean the terminals on the battery, baking soda and water, along with a good scrubbing with a wire brush should do it. That could also work with the cable terminals. Check the power going to the starter and starter solenoid for corrosion also.
