I just finally replaced my agm factory battery and just opted to go with a Everstart Maxx its 800cca.

From my past experience I've seen new batteries go bad and I've seen batteries last for years. there istt really much rhyme or reason just kinda hit or miss.

You can take your car up and have a load test done on it to check it out. But my factory batt was testing about 50-75ca lower then spec so I wasnt waiting for a snowy freezing Michigan morning to have a no start condition

For the 04+, that is correct.

For the 97-03, not so much.

I replaced my factory battery (2002) last fall after not having driven or started the vehicle for a week. It wouldn't start. Tried charging, still wouldn't start.

The previous winter it was a little slower to crank over, but it always started.
