battery

[paulchoi517]

Has anybody noticed that the battery looks like draining a little bit fast if the car is not being driven at all for a few days ? I believe it is due to many sensors running simultaneously 24 hours a day.
All sensors and rear view camera should not be activated until the engine gets started except the sensors for Door Lock/Unlock and Engine Start. I am not sure Telluride sensors and
rear view camera are designed this way. Does anybody know about it ?

About 5% of all batteries will go bad in the first year, industry average for all battery makers. Abnormal drain from the battery after sitting for a few days, is not normal. Report it to kia and have them do a battery test, you will probably need a new battery. If it does not test bad, keep and eye, it is likely to fail in the future. The other option is that you store your keys near the car keeping it active.

Spend $50 on a battery tender and you battery will last seven years or longer.

How does it affect the battery by keeping the key near the car ?

I use battery tenders on my cars. They willprol the life of the battery. Necessary if you don’t drive the vehicle every day.

Most cars that have fobs like the telluride communicate with each other, to be 'ready'. When the key is closer the ping rate increases for things like door locks, trunk, and general accessories. If you turn everything off and just sit in the car, it is surprising how many things are still left on.

If the key fob is near enough, the signaling between it and the car can keep the too awake and drain the battery. And it is not only our key that does this, any proximity key will drain your battery. The car will be in sleep mode, listening for the key fob, when it detects a signal, it wakes up the controller, the controller then sends a ping to the key. At this point, the key response, yes I am your key or not. If it is the wrong key, the controller does a quick pinging session lasting a few seconds to see if the real key is out there and goes back to sleep. If you store a key in that distance, it is possible for the controller to be woke up every few millisconds, stay away for a couple seconds, and then go back, to sleep. Over and over and over. Most systems will allow the controller to ignore the ping of the fob it does not know, but it can not ignore the fob that it is program to.

Today’s key fobs/smart keys provide convenience -- and cause problems

In these days of vehicle owner expectations for their vehicles to perform tasks that would previously require a minor physical or mental effort on their part, the remote “key” has become a mainstay of late model design. Rather than inserting a metal key into a tumbler lock (obviously a task that...

I don’t agree with you. My current car (Volvo) will give a low battery after a week sitting. It isn’t anywhere near dead, but the sensors on these new, advanced cars with lots of sensors do have a high parasitic drain on the battery.

Note, I put in a new battery a few years back and same behavior. It is a 2011 I’ve owned since Jan 2012. Soon to be replaced by a telluride - on order.

A lead acid battery will lose capacity if not kept fully charged. If you drive short distances or if you car sits without being driven a battery tender will extend the battery life. My favorite is the BatteryMinder tenders with desulphation mode. I got 13 years out of a John Deere tractor battery using one of these. Our Telluride will sometimes go a week or more without being driven. I will use a tender regularly on it and likely will never have to replace to the battery during the 3 -5 years we will own it.

Don't take my word for it. Read all about it here:

@hammick - sorry, I meant to respond to @Gwyn .

I agree with you!

ps@gwyn had a lot of good stuff to add, it was just a specific line I disagreed with.

“Abnormal drain from the battery after sitting a few days is not normal”

Agreed it should not be the norm, and you had some good possible causes, but I have a car where this has been the norm for almost 8 years running - new or old battery.

I travel a bit for work and I can anticipate a battery warning every time I am on a trip where I am gone beyond a week. In those cases the car is parked in the airport ramp with the keys hundreds or thousands of miles away.

I have a 1.5 week trip in January, hopefully my Telluride will ready by then. I can update on if this happens with the Telluride then

I don't have any Volvo experience but I think something might be wrong with yours. Any chance your Volvo has a voltmeter in the display? You should be seeing between 14.1 and 14.4 volts when driving at normal speeds. If you don't you may want to put a meter on the battery terminals while somebody revs the car to say 3k RPMs and see what the reading is.
