It has happened again

[Sfcjerryharris]

Well don't know what to say, the battery was dead again, it got cold outside and it was dead, jumped it and she was fine, it got warm outside and she started right up, I'm lost on words, new alternator, new battery, it's just when it gets cold outside the battery dies, but if it's warm outside, it's start right up, can anyone explain please.

Take the battery out or drive the car to a local auto parts store have them test it. Maybe it has less CCA like a weak battery.

CCA are just that for COLD start ups. I have bought plenty of batteries brand new that didn't work for shit when it was cold. Test it and see what the voltage is.

OPs complaint is on cold start ups...

I'd think about a parasitic draw weakening the battery and showing up on cold days. You could try fully charging the battery and then disconnecting the pos. terminal, let the car sit and reconnect on a cold morning. A good start will eliminate the battery/charging system.

I always have this issue when winter comes..

basic battery terminal maintenance always seems to be the fix..
