Recommended Posts

Is it my imagination, or is that battery acid in my engine bay?

It's battery acid. All non-sealed car batteries vent some acid when they charge. If you have a sealed battery, then it's cracked - replace it. If it's not sealed, clean the white corrosion powder off with an old toothbrush that has been dipped in baking soda and wipe it all clean. Then apply a light coat of vaseline or grease to any exposed metal parts near the battery. Notice that your battery terminals were not corroded - they have a protective coating on them.

I'm having the same problem. Second time I took it in (with nice corrosion all over my blue anodized SPT tie-down) they still said nothing is wrong with the battery, but they sprayed it with some kind of sealant.

 

I'm just gonna pony up for a sealed, lighter weight battery with better cranking amps, anyway. Screw it.

my battery holder no longer has paint on it. I replaced my battery last month some time. I have 40k miles on the car and the battery was bulging at the sides and leaking from every possible place.. -1 for subaru and cheap batteries..

 

my positive terminal is almost unuseable its so eaten now as well. I suppose I have no one to blame but myself. If I opened my hood more I would have noticed this sooner.

Yep same here. My 2007 is beginning to corrode and show signs of leakage all over the top of the battery.

 

I might just clean, spray and install those anti-corrosion pads to the terminals.

Probably only $5 for all that vs $100+ for a nicer battery.

I did clean it, several times. The corrosion kept coming back. At the dealership, they coated it liberally with an anti-corrosion grease. Took longer, but the corrosion came back.

 

If the corrosion is a problem for your battery, your best bet is to go to a sealed battery.

 

The good news is that many of the sealed batteries, while expensive, are lighter than the OEM battery.

I replaced the OEM battery with a Braille sealed battery. 15 lbs, 1000+ amps FTW!

 

Thread revival!

 

Did you have issues using the OEM positive terminal with the Braille battery posts? The OEM terminal on my car seems a bit too "loose" for the supplied Braille posts.

...and to go back on topic, the battery in my wife's OBXT went bad suddenly while I wa out picking some stuff up. It had shown corrosion, not as bad as I saw on my spec.B, but it had gradually built up and had half-eaten one of the terminals, not to mention the battery tie-down.

 

Luckily, I was near Costco and just picked up a brand new Optima Yellow Top. I'm done with leaky OEM batteries.
