Fixing a leaky C&D Batt?

For some reason while installing my C&D 300MR battery in the back of my car today, and the negative cap is leaking slowly, when I press down, acid squirts out of the hole, anything I can do to re-seal it, I don't want to throw away a brand new battery.

Where is it leaking from exactly? Can you take a picture? It sounds to me like it was maybe overfilled a little. But ya if it is new and you didn't do anything to it I would take it back.

Yeah a pic may help but for the most part, bad idea to keep a leaker... That acid is no joke. It'll eat just about anything.

Most batteries are not technically "sealed" the gas from the charging process has to be released somehow. If it is allowed to build up to concentrated levels is when you have an explosion.

Alright, so the small cap was leaking, I would push down and a bit of the sulfuric acid would bubble out around the edges, I popped off the cap and found a small pool of acid around the terminal thing underneath, I mopped it out and will be watching it over the next couple weeks and seeing if any more acid ends up under the cap. If so, I guess my brand new battery is simply junk. I will never buy C&D again. Going to watch the Local CL for some Deka 9A31's.

Did you buy it used? That would be a manufacturer's defect if it was purchased new from an authorized dealer.

New from an Online Dealer, don't want the hassle of shipping it back since I decided to go with a different batt setup anyways.

Makes sense.
