Battery leak question
Sorry if this has been addressed or is a repost, but I have a question/concern with the battery in the trunk of my Camaro.
My previous "toy" was a street machine I built and kept for 16 years. One spring, I went to get the car out of the corner only to discover that the top of the battery was covered with the familiar residue of a slight leak that had developed. Sadly, it has cause hundreds, if not thousands of dollars damage under the hood of the car. The acid in the confines of the underhood air corroded everything that did not have a very stout finish. It wrecked the carb, spark plugs, relays, brake lines, etc. Everything cad plated was destroyed.:( Needless to say, it was the final year I stored it with the battery in. So now I buy the car of my dreams and it has the battery in the trunk. Is anyone else concerned or have experience with finding their stock battery doing this inside the trunk pan? I have fixed old muscle cars and cringe at the thought of looking in the trunk in a few years to find out the rust demon was locked up in there festering away for years. Once it starts I know it never sleeps. Has anyone else checked theirs? How much of a pain is the battery to get at? Would the concern be abolished with an Optima? Any help is greatly appreciated. |

Aren't they all?
Are you saying there's nothing on the top like caps? They completely sealed? I thought they all had to be able to vent. I'm certainly no expert, though, or I wouldn't have asked.
I guess I'll have to go exploring in my trunk this spring. Thanks. |

Yea, I've had concerns about this.
Yes, the factory battery is a sealed unit. I haven't shopped for a replacement battery and it will probably be 5 years before any of us really need to replace one. When I had to find a replacement for the battery in my Chevy Colorado I shopped every battery dealer in town to find one that would fit. Chevrolet seems to love to ignore standard size batteries in favor of odd ones that nobody carries. I ended up setteling for a non-sealed one because even the dealer didn't have the "stock" delco battery for a replacement. Will this be an issue as our Camaro's age? I suspect it will. We'll end up with some after market battery that may or may not be sealed, and from then on I can see proglems developing with corrosion in the trunk floor pan. |

The battery is a special battery designed for mounting in the trunk, They are used in some other brands of cars as well. They are not sealed they have a vent hose that runs out of the trunk under the car. They are very easy to get to, just like gaining access to a spare. They have the trunk pad and then the hard spare cover with a large nut to spin off. Mine is an SS so I'm not sure about the other models when you order a spare.
Replacement AC Delco batteries are around $200.

CRAP
That is what I feared. Those caps on the top are what "weeped" on my street machine. I guess I'll have to look once in awhile.
Would a gel battery eliminate the problem? |

They sell a pad that you can put under the battery that will absorb any acid leaks. Maybe put one of those under the battery if it helps you sleep at night. I have one on my '69 because it happened to me once. Cheap insurance.

Its pretty rare for a modern battery to start leaking. You'd probably have to have a overvoltage problem in your charging system that 'cooks' the electrolyte. I'd just inspect it occasionally and otherwise not worry about it.

I'll check it when I get the car out
AND when I put it away each year, I guess. The pad would help but in the case of my Cutlass it was the acid air/environment created underhood that did the deed, not any actual contact with the acid.
Thanks for all the replies! |

I would be concerned if GM was still using side terminal batteries with the terminal below the acid level, but I have not had any problems with top post batteries leaking.

Trunk battery corrosion
My trunk at 7 1/2 years, 127800mi. Orig battery. Checking because it's been weak this week in the AM in the 40s (Florida). Topped off cell 1 &2 with distilled water. Still need to do my rear brakes in a couple of weeks, so when I do, I'll remove the battery and wet clean/neutralize, & see what I can do about the small rust bubbles.
