2010 Ford Fusion mystery annual battery drain. What is killing my battery?
2010 Ford Fusion mystery annual battery drain. Last year I found my cars battery had died. I took the battery in and they charged it and tested it and told me it was good. I stuck it back in assuming it had to be the alternator and my battery would soon be dead again, but no it didn't die… Til a year later it happened again last week. I took it in they charged and tested it and said it was fine. I stuck it back in and it has been fine for a week now. What is going on? No lights were left on. The only two commonalities are 1 it was around the same time of year. (a/c?) 2. I had an male-male audio cord plugged into the aux. (nothing attached unless I was driving) from what I heard that does not draw power.
I heard in AZ people have to replace them yearly because of the heat. Check your ground wires for shorts stuff drawing to much power
Hi I'm guessing here you have never come across the need to change a battery every 3-4 years before caused by suphide build up in the battery itself. This crust builds up over time due the the battery being charged up and discharged over a period this crust build up on battery plates. With in it. So every 3-4 years you need a new battery.
oh yes some do try to combat this with pills dropped in to each cell. Well it sort of works for a few weeks. The result is alway the same a new battery.
Ford cars are also well known for parts that don't last long like alternators they are not well made and don't last long either. So a ready supply is always available.

- I have a 1999 ford ranger, the battery is drained every morning. I traced the drain coming from my left head lamp,? Although the lamp still works but why does it still drain the battery… What do I do? it is the left head lamp that is draining my battery! But why, it still works… Maybe moisture in it?
- Where is the plug to drain coolant on my 2006 Ford Focus? I'm quite sure k-seal has caused a blockage in my cooling system somewhere, as since using it the coolant level has been erratic, bottle empty one day, then higher the next e.t.c. I want to flush old water out ( only use water) but where will I find the drain plug? During flushing coolant, is it just the plug I remove or do I also have to disconnect radiator hoses too?
- Help solve this mystery Blinker problem? '91 Ford Explorer. Right blinker lights are out, also the rear brake-light as it is the same bulb. The blinker on the dash does not blink on the right side (it is solid green) but left side is fine. HERE is the deal: I tried changing the rear bulb but the bulb is fine. The right front blinker lights up fine but does not blink. What is the cause?
