new battery, acid leak AGAIN.. faulty battery, or electrical problem?
when i bought my 02 Z06, the previous owner had changed the battery with an aftermarket type.
The after market battery was installed in october 2004. The OEM battery had leaked, causing some fault codes to show up, and severed a vacume line as well.
I stored my car 1 month ago, and last weekend, i was cleaning the engine bay and noticed that there was some wet area around the battery. I disconnected and removed the battery, and noticed that white/green residue around the screws and bolts.
When i removed the battery, i noticed that acid was leaking out from the top cap/cover area, as if it came out from the battery cap. I brought back the battery to the auto part store, they told me that it is normal for acid to leak out from the top cover because I must have some sort of electrical problem causing the acid to boil and so it has to come out of the cap/cover.
is this true?
also note... since i stored the car, i had a battery tender on it. However, since all the bolts holding down the battery braket were full of corrosion, i suspect that the acid had been leaking well before the battery tender.
