2002 Camry Panasonic Battery.

Mine turned over awfully slow last winter, even with 5W30 100% Synthetic. Dipped to -50 with the wind chill at night where I work. Want to get a bigger battery but would like to know what size I have first.

I see you are in Calgary. That would explain it.

If you find out what type battery exists in your car, you can forward this into to me at snipped-for-privacy@hotmail.com

I believe Toyota Canada has 2 types of batteries: The std. and the heavy duty. You might want to look into this. Also, a engine block heater and battery blanket would help as well when its -50.

Maybe you should consider using 0w30 for those harse winter months. At that temp, the car is going to naturally start slower. I think it is hard for any battery to perform well at that temp. -50 is down there!

Put in the biggest battery you tray will hold, I did this, the battery is 15% larger, it helpes. And get the highest cca for that size. It cost me 110us. But now it cranks at -20, before it barely did.

Windchill shouldn't affect startup. Only actual temperature will affect the ability of the engine to turn over.
