Just noticed a mushroom of white on my negative terminal this morning when filling up my washer fluid. Have had the car for a year and a half and this is the first time this has appeared so now I have a weekend project to clean up along with changing out the spark plugs.
Any luck keeping it at bay or is it something I should start looking out for every so often?
I cleaned mine, then opened up the battery, metal was exposed, shame on me. Filled it up, cleaned it up, drove the car....HAL red eye of evil was on the next day. I kicked myself for not maintaining the battery, checked it a week later, lo and behold the indicator had turned green. Not sure what's up, maybe I restored it, maybe it's about to die...it is 6 years old so its life is likely about over.
I will say this, from here on out I'm gonna remember to check that battery indicator, I check my oil about once a week so both can be done weekly.
