Myryle55 Posted September 28, 2017 Report Share Posted September 28, 2017 I cannot get help with my battery dying problem. I have purchased new batteries, and they just keep draining. I need help please! Quote Link to comment Share on other sites More sharing options...
WWWPerfA_ZN0W Posted September 28, 2017 Report Share Posted September 28, 2017 Welcome! I assume this is the car battery, not the keyfob battery? Sounds like you have what is called a "parasitic draw" that is killing the battery. How many days between installation and "death"? Are you leaving devices plugged into the power points of the car? Are the terminals on the battery clean and tight or are they loose/crusty? Do you have issues with a CD player skipping, or a shifter sometimes not going into Park? OR the alternator is not charging it properly, because starting in 2011 model year, Ford implemented a smart charging system. Every time you put in a new battery, the system has to learn the behavior of that battery. Otherwise, the car thinks it is dealing with the old battery and won't try to charge it properly. The simplest way to do it? Drive it around for the day, then park the car undisturbed for at least 8 hours. The car will keep testing the battery during that time, learning how to best charge it efficiently. Should have no problems after that. The alternator could also be at fault, though your car is relatively young yet for that. Get a Solar BA7 tester, or have a major auto parts store test the battery AND the alternator with a modern digital tester. Quote Link to comment Share on other sites More sharing options...
Myryle55 Posted September 28, 2017 Author Report Share Posted September 28, 2017 It is indeed the car battery. I also drove it quite a few miles, then let it sit for a day and a half to 'learn' the new battery. I unplug everything, turn off the auto headlights and radio and heat/air. It still tells me battery low, start car. So I do that, drive it like 60 miles and it's good for a day perhaps, then it's low again. Makes me crazy, and no one can find the problem in it. Thanks for answering me. Quote Link to comment Share on other sites More sharing options...

WWWPerfA_ZN0W Posted September 28, 2017 Report Share Posted September 28, 2017 How many miles on your Edge? Are there any other electrical troubles happening? I would say get the alternator tested. It simply may not be charging the battery correctly. Quote Link to comment Share on other sites More sharing options...
Myryle55 Posted September 28, 2017 Author Report Share Posted September 28, 2017 42k miles. The fobs don't always open the doors, but nothing else is wrong. Quote Link to comment Share on other sites More sharing options...
enigma-2 Posted October 5, 2017 Report Share Posted October 5, 2017 (edited) If your concerned that it's not your battery and may be a parasitic draw, drawing down the battery when the car is off, try the following troubleshooting procedure. To test for a parasitic draw, disconnect the positive lead of the battery and attach a milliamp meter in series between the disconnected battery lead and the positive terminal. This will show the amount of curent being drawn by the car when shut off. It should be a couple hundred milliamps. (Varies between vehicles). If it's more, there's a parasitic draw occurring. The way to isolate which circuit is at fault, is to pull each fuse, one at a time, and check the VOM to see if the draw has stopped. When it stops, that circuit is suspect. (Note, go through all fuses when you do this to make certain you found all draws). Once you have the circuit, you will need a schematic of your cars electrical system, especially for that circuit. You will then need to start unplugging various connectors in the circuit until the draw stops. Once you isolate the component, you can address it's repair or replacment. Note that this type of troubleshooting will not interfere with a warranty or extended warranty. You can buy a cheap multimeter (called a VOM or Volt-Ohm-Milliamp) meter on Ebay for less that $10.

RDL1000 Posted October 13, 2017 Report Share Posted October 13, 2017 By any chance are you having the "Door Ajar" light coming on? Before I purchased my 2012 Limited I did a bit of research on safecar.gov and car complaints.com and both make reference to the door ajar light staying on in the dash which drains the battery. In fact the majority of issues dealing with electrical and/or the battery was dealing with the door ajar light. Hope this helps. RDL Quote Link to comment Share on other sites More sharing options...
ADAM_O Posted November 2, 2017 Report Share Posted November 2, 2017 i have a 2012 ford edge and my battery just started dying and i had it checked and my altenator checked at les scwab and both were fine apparently. My battery will not say it needs charge when hooked up to charger but when hooked up to my car the car acts like its low on juice then dies after a few minutes of being hooked to car help Quote Link to comment Share on other sites More sharing options...
WWWPerfA_ZN0W Posted November 2, 2017 Report Share Posted November 2, 2017 Did the shop check CCAs on the battery or just Voltage. Voltage is a false indicator. Unless there is a parasitic current draw and/or the alternator is not charging correctly, the battery likely needs replacing, especially if it is the one that came with the car. Replace with a Group 65 AGM type battery for best operating life. Allow the car to sit 8 hours+ undisturbed after you park it for the night so it can learn the characteristics of the new battery.

akirby Posted November 2, 2017 Report Share Posted November 2, 2017 If the battery is more than 3 years old, replace it. Then get a Solar BA-7 tester. Just think of how many battery sales they're giving up by not having the proper test equipment (or not knowing how to use it). Quote Link to comment Share on other sites More sharing options...
