Sorry for the late response. I just now found your message. Please respond as a reminder and I will dig it up on my computer. I inspected all tsb's for all my vehicles, I read this one in particular.

I bought a battery blanket (heater) and the main problem is a basic battery concept that a cold battery has a reduced capacity. So when it is very cold, the car thinks the battery is fully charged even if the actual capacity is low.

The location of the battery is the main problem. Because it is in the trunk and other the floor, it never warms up when it is cold, even if you drive the car for a long time. I had a heated garage which I kept at 10C all winter long and when the car is cold soaked for a full day at work, the warmer fixed it right away.

As soon as I started warming the battery while working (Saskatchewan, -30C weather), the problem actually went away... until I stopped. No real need for a trickle charger if you get the warmer. The battery will properly recharge as you drive. It is cheap, like 50$, and the install takes a few minutes. Unfortunately the cable will be in the trunk but it still works really well. I would close the hatch on the cable no problem.

Good luck.
Excellent point in regards to the location of the battery. I'd imagine that impacts the useful life.

I always replace batteries when it's ~5 years old.
