Swapped out the battery on my 2000 Avalon in 2006 (age 7) just because the OEM
battery in my '81 Celica finally died after 7 years.
All you need to do is occasionally give your battery a trickle charge for a day or two, to get longest life out of them.
(( What gets pulled from your battery by those little LED lights, and transistorized alarm systems is negligible. ))
All my cars now fitted with inboard trickle charger from Harbor Freight LINK
$15-$20 on sale, and $$ well spent.
