    Battery Life

    How long do they last??? My 2011 summer only driven Charger has the original battery which works well. I start the car every few weeks while it is parked for the winter in underground parking. Will it last another winter or should I play it safe and go with preventive maintenance? I replaced the original battery in my 2005 Magnum after 9 years (it was working fine) only to sell the car 3 months later. My parts guy has his original 15 year old battery in his Ram truck.

    Have you had it tested? Essentially when you have oil changes performed a battery test is included with the service. Should give you an idea of battery state. OR if you just want the peace of mind replace it.

    I'd just run with it until it dies and then replace it at that time.

    Funny you should ask. I went to the Interstate Battery store. I asked to have it tested. I would have to bring the battery inside the store as they don't test in the car due to Covid-19 restrictions. I asked for a price...$375.00. BUT they don't have my type of battery and probably won't until next year. Some kind of demand and shortage due to Covid-19. I asked if that price included installation. They don't install due to Covid-19. The dealership I work at has 3 in stock priced at $200.00 + install ($25.00) Parts guy said to wait 'til spring when it makes more sense to see how it survived the winter (starting it up every 2-3 weeks instead of every 6 weeks, like I have done since it was new.)

    P.S. I had the oil changed exactly 1 year ago. Have driven 500 miles in the past year!!

    Run it until it goes bad. My 12 RT Charger got 7 years and 185K miles on the original battery. But, I’ve had other cars where the battery went after three years— car battery life generally is all over the map.

    At the shop, most batteries seem to go between 5-8 years. On my cars and parents cars I change them at 6 yrs. because most of the time it happens at the worst time. Most of the time, outside temps like 90’s or higher or lows like 40 or below kill older batteries. Just my observation.

    9 years? I'd change it now and go with the dealer OEM battery.

    If you try another brand which after the OEM lasted all these years I don't know why you would, make sure it has a vent tube and it gets hooked up.

    Have it "load Tested". Most auto parts stores just read the voltage and if it above 12V it is okay. BUT... it could have a partially shorted cell which restricts its max power.

    Cool

    5 years or more is really pushing it with a battery. I have seen original batteries last up to 12 or so years but anything can happen before that. If you use a maintainer like a Battery Tender I'd say maybe you could get away with it.

    Interstate was probably trying to sell you an AGM Battery, which our cars did not come equipped with originally. Group Size H7/94R. If I remember right, the Larger H8/49 used in Police Models was an AGM. Batteries availability on the dealer level has been an adventure for a few years. When PGW took over from Interstate as Mopar's battery supplier it all went downhill fast. It took forever to get batteries. In the last year a battery distributor owned by Exide took over, and it has improved some.
