Leaking Battery

I changed the oil and rotated the tires on my car this weekend.
I also deleted the snorkel. That's in another thread.

In the process, I discovered that my battery was leaking, and had been for a while. There's lead sulfate splatters all over the inner fender, and there are rust bubbles on one of the cross members.

My car was built in May 2011 and has 44,500 miles on it.
Check your batteries. Better to find out now than get stranded.

Yes, you need a new battery quickly.
And checked charging System.

$140 at Advance Auto Parts and they installed it for me.
I got it swapped right after I put the oil in the engine.

I would pull out the battery, the battery box and what ever else there is below it checking for damages. I recently had a battery leaking a lot of acid which ate my transmission shift linkages as well as the hydraulic line between the master/slave clutch cylinders.

Did they run diagnostics on your charging system? If not, you may have a recurrence of the same scenario.

No, but now I'm paranoid. I'll try to test the alternator this week.

The Ford Focus has a Smart Charge charging system. This is a special charging system.
You can not charge the battery with standard charger. These destroy the battery.

But you're right. Check the charging system and alternator.
You have Start/Stop system in your car ???

No start/stop.
I have been checking the voltage using Test Mode while I've been driving.
My voltage consistently shows 13.5V or above while driving.

FWIW, test mode is incredibly distracting while driving. Especially when you go to Gauge Sweep, LED test, or the Test Pattern.

Start/Stop hasn't (thus far) made it to Canada/USA.

Don't be paranoid.

The charging system is quite intelligent.

It is highly unlikely that you would have a problem without some kind of notification.
