LOL.....good rule of thumb is, ......after 3 or 4 years, if it hick-ups, Get a new one!
Some of my cars have 4 to 6 year old batteries, but I keep them up on trickle chargers, and they seem to perform well.
This is OK when you only drive a car every other month.
If it is your daily driver, just get a fresh new battery every 3 to 4 years, and if you are lucky, you won't get stuck with a dead one!
Check your spare tire, and jack, as well.
Fill the spare tire with 40lbs of air, and check it every time you service the car.
It's so, easy to do at home, but so hard to understand, why you don't have it on the road, when you need it.
Just say, "Happy Holidays, to Me" and buy a new Battery!
It will make you feel all Good Inside!
