    I bought my Challenger SRT 392 in March of 2015 after deciding I wanted a fun car as a second mode of transportation. So far I have loved the car up until a couple weeks ago when it started acting up. The car sat in my driveway for two and a half weeks straight while I was on a business trip and now won't start. I tried hooking up a booster cable from my Subaru and the screen came up saying Accessory Mode Turn key to start. I pressed the start button and the battery died. I then tried charging it with the auto battery charger I had in my garage. The battery wouldn't hold a charge. Has anyone else had this issue with theirs? Is there a simple solution for it? I travel a lot and I can't be stuck coming home to a vehicle that doesn't run even though I have two other vehicles I can drive. Any advice would be greatly appreciated. Thanks

    Do you have a big boy charger to put on it? If not every garage needs one, Sears DieHard works well

    my 2011 would die in storage after 6 weeks....called dodge to complain and they said it was normal...2 weeks sounds too short for this issue (mine sits for 2-3 weeks w/o an issue)

    for winter storage you need a battery tender for newer cars

    buy a new battery see if that helps.......otherwise get a battery tender for $20

    If the battery was dead after 2 weeks there is a problem. Do you have any aftermarket devices connected such as a OBDII device, USB charger, etc?

    If not you either have a bad battery or parasitic drain problem.

    Leaving the vehicle set 6-8 weeks could cause a dead battery, use a Battery Tender.

    Take it to you dealer and have the battery load tested. I have had new car batteries fail after a few weeks, I had a new Honda battery fail the next day after buying the new car. Bet you have a defective battery and will get a new one free. Not uncommon for a new battery to fail, at least not for me. If it will not hold a charge its bad!
    Good Luck!

    I strongly recommend a Battery Tender unless you live in CA. Where they cannot be sold. I have a small collection of cars that sometimes sit several weeks before I can exercise them all including my Hellcat. With the Battery Tender I never worry about a dead battery.

    Robert,
    I don't own a Hellcat yet but I've owned a lot of vehicles in my life but a battery going dead in two weeks isn't normal especially on a new car.
    I live in Texas where it'snormally hot so is this a cold weather thing?
    Call me paranoid but I'd take it to the shop and make sure there isn't a electrical short and or if you got a bad battery.

    normal IOD (ignition off draw) on any dodge vehicle is 5-35 milliamps. this can kill a fully charged battery in as little as 3 weeks.
    a less than fully charged battery likely wouldn't last as long. although 2 1/2 weeks seems short, it's actually not that bad.
    i would ensure the battery is fully charged, then load test it. if it passes, an IOD test would indicate if there is excessive draw.
    my recommendation is; if it's gonna sit for over a week, get a battery tender or carry a booster pack.

    I just re-read your post and see you have a Srt I had a 2013 Challenger Srt8 and there were times I would let her sit in the garage for a month at a time and I never had an issue with the original battery. I own several vehicles and I take turn driving all of them.
    The 1997 Dodge truck I just gave to my son was sitting for a good six months and it fired right up. Once the factory batteries get old I replace them with a Die Hard battery which the truck had.
    Good luck

    Im a big believer in a Battery Tender well I prefer the off brand ( the ones sold at Advance auto works great) as I have had at least 3 Battery tender brand go bad over the years. I use one on my Harley and I have got up to 7 years out of a motorcycle battery using one so Battery maintainers are wonderful and WILL make a batter last!
    However, OP says his battery will not charge even when using the auto charger he has in his garage... He has a bad battery that will require replacement. New batteries do fail.

    maybe his charger is defective or he doesn't know how to use it. Most people think a trickle charger will charge a dead battery in a couple of hours, when in fact, a completely discharged battery can take up to 30 hours to fully charge.

    Uh, I have a battery tender I bought at harbor freight, and they also sell them at Home Depot? Not sure what you mean that these cannot be bought in CA?

    I don't know who makes Mopar batteries but I've had great luck with them. My original '01 Dakota battery lasted 6 years. My original '08 Challenger battery also lasted 6 years. When it died I replaced it with another Mopar battery. I used to swear by Die Hard Gold batteries but the one in my wife's Toyota only lasted 2 1/2 years. Sears gave me a new one.

    CA passed a law in 2014 requiring battery chargers to be more energy efficient. Battery Tender Jr. does not apparently meet this requirement. Amazon for example list product as not available in CA.& OR. Also Deltron Battery Tender web site shows Battery Tender Jr. not sold in California & Oregon
