Pulling out battery during winter saving cranking amps??

[ellisjay2]

Does it help to pull the battery out of my truck due to not having a garage from the winter, its getting down to the low 20's now here in north ga, its been cranking good with carb and electric choke, but is starting to sound weak on first mourning crank. Someone told me I should take battery out and bring indoors and put back in next mourning when leaving from overnight to help save cranking amps/ make cranking better....I will be buying another battery soon to get fresh start on winter on the way to snow season.
