Currently 15 degrees here in Berks County Pennsylvania. Went out to start the Acura in signature -- have not started it the last 3 days and its been brutally cold with the wind especially overnight. Hooked up the battery tender for the time being. Will be using the car to go to church later. I am sure a good drive would take care of it also. Really caught my attention though initially with the crank. Just purchased the Walmart battery last year 2021 right before winter. Middle of the line price wise battery they had.
