Default Battery Question

I have a reproduction battery for a 66 corvette that was purchased some twenty years ago but never activated. I've added acid and charged it slow with 2amps until it reached 13.7 volts. I tried starting the car with the battery but it cranked a few times and died. I checked the battery voltage and it was dead. Any ideas why this battery isn't holding it's charge?

I would have to guess, but setting empty without acid, the plates may have heavily oxidized. I don't know if there is a way to restore the battery or not. The used car dealers are putting rebuilt batteries in the cars which don't seem to last that long. When we bought the 2014 Stupidroo new, it had a non-branded battery that I think the dealer swapped in. It didn't last two weeks. The dealer's service manage said it was because we left the rear dome light in the OFF position. Had to contact Stupidroo of USA to get it replaced with a factory battery.

Okay, what’s a Stoopidroo?

We bought a new Durango R/T Hemi 2 weeks ago. We call it a Dingo.

Take care,
Steve

14' Subaru Outback, my stupidest purchase in a vehicle. Consumer reports said it was the most reliable vehicle at that time - they lied. Started replacing parts at just over 30,000 miles.
The 07 Impala it replaced never needed anything but gas, oil, and tires for 106,000 miles and got 50% better mileage even though it had more power, not to mention the ride was 10X better.
Cheap car for kids.

New Subarus are still highly rated. I briefly thought about one before buying the Durango. And as a bonus, since I traded in a Honda, I now have an All-American garage:



Take care,

I apologize to the OP for starting the deviation / hi-jack.
He may want to talk to a used car dealer to find where reconditioned batteries are brought back to life. One would think a new battery stored without acid would not degrade. There are U-tubes for what they are worth, but I don't have much faith in them.

Ron:

You were. correct in your reply #4 above. Plates heavily oxidized. Some batteries like this can be "brought back" but even then they are not really reliable and long lived. Appears OP battery took a "surface charge" but never really a proper "deep charge". There may also be other internal issues. Best OP can do is try to use time to his advantage and play with various charging techniques to see if he can get battery to bounce back. Maybe fast charge-slow charge-fast charge.................something like that. He can also use a wet cell battery tester(sp gr. tester) on each cell to see what that shows. That is the proper way to gage battery fitness and health.

Years ago I used the early reproduction wet cell batteries (many) for my 67 car. No matter what I did, the best I could get was about 2 years life. Some were easy to add acid and bring back to life, and others were not.

Worst case, OP could use the reproduction case and install a gel cell type battery inside the case. There are a number of folks that did this, and the steps are on the internet and NCRS website.
