Why replace the original 3 year old battery?
I am somewhat
jaded b/c both my Malibus (09 & 13) battery died at 41 and at 34 months.
The last battery episode lasted two weeks before the dealer replaced it under warranty. Prior to that I had to jump start it 3 times and it caused hours of frustration. It kept testing "fine" by 2 shops who honestly/shockingly didn't want to sell me a battery.
Lastly, the Frequently Asked Questions from the ACDelco warranty page:
"What is the warranty on the battery that came with my vehicle? It says that it has a 42 month no charge warranty. (Example: ACDelco Professional PG Series)
The
battery that comes with a GM vehicle or is replaced under warranty is covered by the limited warranty of
three years or 36,000 miles (48 months/4 years or 50,000 miles, whichever comes first, for Cadillac and Buick)"
Our two SUV (Equinox and Uplander) OEM batteries lasted 5 years and 7 years though. I was grateful that my
replacement battery was free. I would have paid to get a better one, but wasn't given the option. My "new" battery is warranted for 36 months.
OP is getting their first BU, might as well eliminate the potential risk bad times etc and just be HAPPY....CPS
