  • Both. All battery terminal corrosion is from a leaking battery terminal or acid somehow making its way onto that connection, it is NOT caused by the electricity or anything like that, it is 100% of the time acid touching the metal and causing a reaction.

    It is very hard, pretty much impossible to bond lead to plastic, most batteries are manufactured with an o ring embedded in the plastic to seal against the lead terminal. This often doesn’t help, acid wicks up and out.

    Best thing to do is start off with disconnecting and cleaning the corrosion off of the terminals, install those felt anti corrosion disks, they soak up and neutralize the acid under the terminal where it’s coming from before it wicks up into the connection, protecting it, then spray it all down with battery terminal protectant, you’ll never have a corrosion problem after this.


  • It’s pretty easy to test your clutch for slippage (it being burnt out). Get on the highway in your highest gear, then just floor it. If the rpm’s shoot up, without speed increasing at the same rate, your clutch is slipping. If you floor it and the rpm’s stay low and slowly incrementally increase with speed, then your clutch is grabbing fine and it’s not an issue.


  • That doesn’t sound like a bad battery. Best way to “revive” a bad car battery is to charge it. Leave it on the charger for a week, if it’s still not good, it’s bad. The only way a lead acid battery might be able to be revived is if it’s sulfated, overcharging, or leaving the battery on a new charger that will trickle charge the battery will usually break this sulfation up, but it takes time, usually a week. If it doesn’t improve after a week, it’s not sulfation, it’s something else like broken plates, a dried out or shorted cell, something that can’t be fixed and the battery is bad.

    Most car batteries don’t come back after they’ve failed, I’d personally just throw in the cheapest battery you can buy, like a $50 Walmart special, and just know it’ll need to be replaced every couple of years.
