Connect your charger to the terminals in the engine compartment, and you should be able to pop the trunk.

 

The battery charger has a 75 amp "quick start" switch on it, I've used it on my Expedition with success. Can I use that through the front engine compartment posts?

 

I do have a auto battery charger, and have used it on my truck few times, but I know the battery in my R/T is a little different.

The battery in you R/T is not different in any way. All flooded lead acid batteries are the same, and your auto charger will work perfect.

So what killed your battery ?

A "battery tender" from Deltran is the only way to maintain a proper charge over a long period of storage. We use them on everything from stand by generators to ATVs, Harleys, cars, trucks and have never experienced a dead battery....only if you have a good battery to begin with. My R/T battery failed the first day it was defective replaced by dealer and fine now.:bigthumb:

 

i have mine hooked up to battery tender too they seem like good product,truck and mower too :thumbsup:

 

As Mokeman3 said, just recharge in auto mode on the charger. Avoid the "Boost" setting unless you really need to get up and go. Just a nice overnight re-charge is all that's needed. The Boost setting send a lot of current into the system and that's never a good idea.

Slow and sure is best...IMHO..

 

HI All
I have a 08 srt8 up here in Toronto. Since I purchased the car, june 08, I have had problems with hard starting. It cranks once or twice then evenually starts? the dealer has replaced the starter, and a left fuel pump? and now, since it is winter up here and the car is put away for the winter, everytime I try and start it ( about every 2 weeks ) the battery is dead. Any ideas? Could the problem have been the battery all along?
thanks guys

 

Sounds like a bad battery or you have something drawing too much parasitic battery current when the car is shut off.

I tested the parasitic current on my 09 SRT and it was only 30mA. This would take at least a couple of months to drain a good battery.

Look for the problem and also get yourself a Battery Tender.

 

dead battery

HI all
I did get myself a battery tender, but after 24 hours of charging the battery tender indicated that the battery was defective and should be replaced!

Now, being Income tax time, I was going over my invoices for my vehicles, and came across the sheet from the dealer ( last time serviced before putting away for winter ) a note from the lube person, that the electronic battery test indicated that the battery was very WEAK! You think that since the car was in for a hard starting problem, that maybe someone should have looked at the battery.... apparently not. I called the dealership and told them what I had found, and they replied " I guess we owe you a new battery" So I guess I will have to wait until spring to start the car again.

I did learn 2 things, one about battery tenders... great little machines
two, actually read the paperwork I get from the dealer.....

thanks for the help

 

How are you going to start the car in the spring to get it to the dealer? Before I risked having it towed to the dealer, I put a new battery in it myself.

 

HI
I am hoping that I can boost the car to start??? and if they have to tow it, they better send a flatbed, there is no way I will let it be towed any other way..... I am a 54 yr old woman, and I do not think I could even lift the battery out and I do not think that the dealer would let me do it anyway??
P.S. being a woman, I do not think they really pay attention to me when I tell them there is something wrong... even though I was married to a Service Manager for 18 years... sad but true

I will keep the forum updated on my progress. thanks everyone

 

Dead battery...

Hello all, like many of you on here i've experienced battery issues with my 09 SRT8...they have just resulted in a few crank overs typically...until today when I went to pull it out of storage. It has been started religiously every two weeks all winter...but now it has decided to hold itself hostage. The doors are locked...so that means no access to the hood release...however...knowlege to me after downloading the owners manual...since that also is in the car... there is a valet key in the key fob...according to Google...Brad Pitt also had this same brain fart!

Just thought i'd try and save someone else this same hassle...and yes a battery tender is tomorrow's purchase!

+1 hemigirl, a battery tender is the only way to go....starting her up every 2 weeks is not the best idea...just leave the car off(sleeping) & hook up a tender, if your battery is in good shape, the "tender" WILL solve the problem!!:thumbsup:

 

Hey Yall,

My 09 R/T Auto has been setting a month or so and my battery is dead. I've had a charger on it for several hours and tried to start it with the "start" selected on my charger with no luck. I called my service advisor and she said it was still under warranty but that I would need to call roadside assistance and have her towed in.
I didn't like that answer so I trying you guys. Any other ideas? I did try to jump start it but no luck there either.
Thanks,
Rod

 

If you are not in a hurry, leave the battery charger connected at normal charge rate for at least a day. It may start to take a charge and come up.

However in my experience, any auto battery let go flat dead will suffer some damage long term. You may want to go the route of having it replaced under warranty if they will.

BTW - Your battery should not go dead setting for 1 month. 3 months, yes.

And when this is all resolved, get yourself a Battery Tender if you plan to leave the car set for weeks at a time. It will save you grief and ruined batteries.

 

Here's some helpful advice about charging a dead battery:

If your battery becomes totally discharged, you should re-charge it (for 3-4 hrs.) with a proper battery charger. Don't just jump it and expect your alternator to re-charge it.

Late-model cars take large amounts of current to operate such things as fuel pumps, fuel injection, PCM, and lots of other electricity-consuming accessories. That's why most cars have 100-amp or larger alternators. Running all that stuff, while trying to resuscitate a really dead battery, can make an alternator overheat and become damaged.

However, if you don't have a charger, start by hooking up the jumper cables to the two batteries and letting them "chat" for 30 minutes. Don't run the engine on the donor car. This will put at least some charge into the dead battery. Then start the donor car and let it run at fast idle for 10-15 minutes to add some more charge. Now start the dead car, but turn off as many accessories as you can (e.g., A/C, defroster, headlights, etc.) until the car has been driven for a couple of hours, on preferably an interstate (i.e., avoid stop-and-go traffic).
