At least a week ago I noticed this email like icon on the information display. I thought it had to do with the Bluetooth or something. I finally figured out it was a message that reads "Battery Saver Mode".

It will not clear, been on constantly at least a week and a few hundred miles - no symptoms. Battery seems strong...cranks right up even when 30 degrees...

Ill show the dealer soon when I get the two new front wheels.....any hints as to what this is?? One of the few things these cars seem to lack is an ammeter...:(

I was going to post this same subject. It's been 0-10 degrees for a few days and I have been using the remote start more. Like you the one day I had a message and sure enough it was the battery saver mode. I did just get the message once this was 2 nights ago. I did not get it today. My guess is its just minimizing power so the battery can recharge quicker with the alternator due to extra drain on the battery. Just taking a guess here

I have a 2013 AWD RT

lg, I'm betting that this is some fancy computer controlled setting that is glitchy...

Think about it....370 hp and Dodge couldn't simply put a bigger alternator on the car??

But I have been using the remote start a lot. And on another forum I noticed folks tying the remote start to this message. I'll not use the remote a few days and see if it clears.....

The message is due to low battery voltage. The link to remote start seems coincindental since it's usually only employed in very cold weather.

The root cause appears to be a bad alternator (factory defective) that isn't charging the system properly. Several have fried and at least one customer had it catch fire.

The system is designed to reserve enough power to start the vehicle and doesn't let you run the ancillary systems and draw the voltage down below an acceptable "start" charge. The issue appears to be that the system isn't recharging the battery enough and the "battery saver" program is kicking in.

Now that it's cold enough to expose this issue, expect a TSB from Chrysler soon.

DDaddy that makes sense....

Now that you explain it that way, it does seem like sometimes the seat heaters are very slow to work and other times they fire right up......that could be the system activating....

I will be at the dealer in a few days anyway getting 2 new wheels, they can check the alt.

thanks much

Now does this make the car more "interesting" to drive knowing it may spontaneously combust on you?:confused:

But on a more serious note..... this battery saver mode is this only on the new chargers or do the older styles have it also?

Yikes! Looks like I might be taking her in to get a new alternator. Thanks for the posts and info.

If Dodge had put an ammeter gauge in I would have known from the start what was going on....one of the few deficiencies I have found in the Charger.

But then I am a 56 year old engineer, my daughter wouldn't have a clue what an AMP is anyway so I guess it is a good idea.

Problem is, with cars, computers, everything......the more "idiot proof" they are made,..... the more "idiots" we are raising.....people can get through life understanding less and less about the world......

....I hire new college grads and most are engineers so they are ok. But you can get a business or accounting grad with a 4.0 GPA and ask them to hand you a cresent wrench and they give you the channel-locks. They get a flat, they are clueless and simply call dad......

Agreed, need at least on course in mechanics...(this is a flathead screwdriver, this is a phillipshead....etc..;))..I just use my volt meter in the evic to check charging voltage...

Yep, the ones you see on the side of he road with hood up and scratching their heads, "yep, must be a flat tire" and don't have a clue what is wrong.

As far as he battery, I was on borrowed time on mine when I traded her. 6 years and well over 100K miles on the original OEM battery.

6 years....exceptional. You must have drained and recharged it a lot. What a lot of people don't know is a light duty cycle on a lead acid battery is actually bad. If you only drain it 20% and then re-charge .....pretty soon 20% is all it can give.

People call tools by many different names....
Cresent is actually a brand name, not the name of a particular tool one might refer to.
http://en.wikipedia.org/wiki/Crescent_(brand)
Most of the time people want an adjustable wrench.
They did make quality tools up until a Chinese company bought them:
Apex tools owns them now.

In Mr Goodwrench's case; a miter saw....
Just a little tool Humor.

Took my charger out for the third time since I've owned it and at 191 miles the battery saver mode message came up. Disappointing.

My selling dealer has not seen any other instances of this message and asked me to double check what it said. It'll be going in to be diagnosed this week.

I have started seeing the same issue on my 2011 Charger.
I am in TX and its very hot right now.
I am only seeing this when using remote start and it does not happen each time. Whenever the message shows up, turning the car off and on right away makes it go away.

I have started it up many times manually and this message has not shown up.
When using remote start it shows up about 1 out of 4 times but there are no issues with starting though.

I took it to AutoZone and O'Rielly and they both ran the Starter and Charging System tests - Alternator, Battery and Starter all passed.

I am dreading taking the car to the dealer but I am at 34K miles so if there is an issue I want it fixed before the warranty is up. Seems like a computer or a remote start glitch...

I just got the "battery saver mode" message tonite. I will take it in the coming week.....bummer. If it is the alternator, I am going to have the parts guys get me the police alternator...I think it is 220 amps.

So! I'm guessing, by what the engineer said, that the alternator doesn't have enough capability to run the whole system at idle speeds; thus the computer begins to selectively shut things down, or lower their application amperage?:serious:

Yup, funny how they make the base models expandable with Bluetooth and heated seats etc and yet it can't even run everything it is designed to. Mine died and put a 180amp alternator in it. Problem solved. I don't have remote start and the battery saver mode message would come on 3/5 times a few minutes after starting it and the rest after I had been driving for about 10minutes. Center console would shut down, heat and ac stopped working. Parking it at home until it was fixed.
