I've never had a starting battery go beyond 5-6 years but then again it's best to change them before they leave you stranded.
We had 1997 Varta battery working 13 years on our Mercedes. Have seen reports about 17 years as well.
Kirkland 100-months battery died after 50 months, so I got some money back.
The current 96-month Bosch battery is about 5 years old and I use it in camper as we speak.
Amazing I can have lights, fridge, water pump + fan for whole night and the 100 amp-hr battery still has good voltage in the morning.
