Default Repeated dead battery

I let my car sit for a whole week unused during that cold spell last week. Had to jump start it, no issue there. Battery is an interstate green top and is only 2 years old. Have had issues lately with corroded battery terminals creating a bad connection so every now and then the car would be ďdeadĒ but actually was fine once I cleaned the terminals.

So after jump starting with my jump pack or cables, the car will run fine and after driving around town, will start right up with no hesitation. However if I let it sit overnight it will be dead. It may crank once or twice slowly but wonít start. The battery terminal was replaced yesterday thinking it was the issue, but again this morning, barely cranked and also barely cranked with the jump pack. Finally got it started and drove 45 mins to work. Once parked, i shut if off and tried to restart, started right up with no hesitation.

So basically it can hold a charge temporarily but sitting for hours it dies. Is this typical dying battery? Maybe letting it sit for that cold week at 10į toasted the battery totally? Even a completely dead battery will slow crank when being jumped? I donít think itís a short, never had an issue until I let it sit. Gonna get a new battery today but wanted to get opinions before I paid for one.

I have the same battery in a couple of our cars in N NJ. All the batteries are a couple years old, cars have been sitting outside in the same weather, each just cranked over fine yesterday.

Have your battery tested, it could be just dieing.

Standard troubleshooting, test battery and fully charge on an external charger if good or replace if bad, test alternator, check all main power and ground connections for corrosion and voltage drop and fix as needed.
Doing the above should take care of it, if there is still a drain problem after all that then it's time to do a parasitic drain test.

Car started right up after my 45 minute commute quickly and without hesitation. But if I let it sit for a few hours, dead. Gonna bring it to my buddy's shop today and have him pull the battery and test it again.

Easy (as I stated before, Mulder also commented ), do a battery test.
Sucks a battery can fail, but sounds like check it first.

Any other recent electrical work done?
New electrical work may be adding a drain killing the battery voltage.
Then again, crap happens, maybe a bad battery.

Take from a long term auto guy, 14+ years in the datacenter UPS business.

THe combination of cold and letting your car sit killed your battery. You'll need to replace it.

Replaced the battery, all is well again. Interstate prorated the cost of the new one under their warranty.
