Our cars suffer in the cold too. AAA says at zero degrees, a car battery loses about 60 percent of its strength. This means body shops and mechanics are busy.
Batteries Plus Bulbs staff tell News 18 car battery sales have been non-stop. Their sales have doubled, selling between 50 and 70 batteries in the last two weeks.
"During cold snaps like this, we always try to plan ahead for these and keep things in stock," said Brain Smith, store manager at Batteries Plus Bulbs. "But then again you just never know. So, anytime it gets below sub-zero, we start to run out of stock."
Staff say the cheaper the battery, the shorter the lifespan. They also say the extreme cold exposure and the age of the battery are the main factors in how long it'll last.
