silversand,
As you know, we have a 2004.5 Chevy also but it's the 6.6 diesel (D/A) which has 2 big starter/acc batteries also. Just replaced the OEM batteries last year at 11 years old and over 160K miles. Still started the truck fine but sure didn't want to be somewhere with 2 dead batteries so it was time! Never disconnected them once as the truck (only used since new for RV use with either the Lance TC on or our Carriage Carrilite 5th wheel) very rarely sits idle for even a week.
Heck, I never disconnect the boat batteries for storage from around the first week in November till in May and they are 8 years old now. NO battery minder ever used and the engine starts right up always. Don't disconnect our RV's batteries when in not used season either and have never used a battery minder. Never had them go dead or below 70%. Just fully charge them before storing! All our very MANY (11) batteries are the flooded lead/acid 12V and most are group 31 deep cycle 215 to 225 minute reserve at a 23 amp draw except the truck and SUV starter batteries.
Probably helps a lot that where we live in West Michigan on the lakeshore we don't get below zero F at night or over 90F max as that can really hurt battery life etc.
