I`ve had my civic parked up in Edmonton Alberta, Canada since the end of Oct and decided to start it up today. I know it gets cold here, so i gave her a boost and started it right up. I let it run for about 10 mins, then shut it off, and went to restart it since it was warmed up. Almost dead and wouldn`t even crank over. The batter is new from this summer, so i yanked it out only to see how bulging it was, talk about frozen! I had no idea they expanded so much. Here;s a pic of what it looked like, crazy

 

lol damn will it work after it is thawed out i don't think so but who knows baller status Acura battery

 

lmao throw it in the oven

 

I know Honda used to have a battery warmer. It was an accessory back in the day.

 

keep it on a trickle charger. all over the place on ebay or a motorcycle shop.

Mine has auto shutoff so you can set it and forget it.
