Depends on how they've been treated. Maybe depends on which brand you've got too; dunno.
FWIW, our oldest starting/house bank of 3x Group 31 AGMs (Odyssey) has been through 9 seasons. Not saying that's average, though.
And even though that bank still seems fine... of course I'll be paying close attention to how well they still hold charge come this Spring.
