+ 01 Battery life in Boulder
What Boulder does to a battery
Winter is the test in Boulder. As the temperature drops, a battery's available cranking power drops with it, while cold, thickened oil makes the engine harder to turn. Around zero degrees a battery can lose roughly half of its starting power, right when the car needs the most. Batteries actually age more slowly where summers are mild, so many reach four or five years here, but one that has lost capacity gets found out on the first sub-zero morning.
From the Boulder notes
- Warm, sunny afternoons can turn to snow, and the freeze-thaw cycle stresses batteries, seals and tires and opens potholes on the main streets.
- Cold mornings expose weak batteries all winter.

+ 05 Questions
Boulder battery questions
How long does a car battery last in Boulder?
Often four to five years. Cool summers are easy on battery chemistry, but winter is where a weak battery gets caught, so a fall test matters more than the date on the label.
How many cold cranking amps do I need in Boulder?
At least what your vehicle's manufacturer specifies, and a little above it is reasonable in a cold climate. CCA is measured at 0°F, which is exactly the kind of morning that matters here.
Can a battery be replaced outside in the cold?
Yes. A battery swap is a quick job and the tech does it in driveways, parking lots and garages all winter. If the car is snowed in, clear a path to the hood and the tech handles the rest.
Do you bring the battery to me in Boulder?
Yes. Call the number on this page with your year, make and model and where the car is. The tech brings the right battery, tests the charging system and installs it on the spot, at home, at work or at the roadside.
What if it isn't the battery?
The battery and charging system get tested before anything is replaced. If the alternator, starter or something else is to blame, you hear that first, and the Mobile Auto Repair page for Boulder sends a mechanic for those repairs.
Do you take the old battery?
Yes. The old battery leaves with the tech and goes to be recycled, so there's nothing for you to haul anywhere.
Not the battery?
Need a mechanic in Boulder?
If the test points to the alternator, starter or anything else, Mobile Auto Repair sends a mobile mechanic to Boulder for the repair.
