+ 01 Battery life in Juneau
What Juneau does to a battery
In Juneau, the cold is the whole story. At twenty or thirty below, a battery has only a fraction of its normal cranking power and the engine needs far more to turn over, which is why block heaters, battery blankets and cords through the grille are everyday equipment here. A battery left at a low charge in deep cold can even freeze and crack. Most batteries last three to five years, and the ones that last longest are kept charged and kept warm.
From the Juneau notes
- Short trips are the norm here, and a car that never fully warms up builds moisture in the oil and slowly drains its battery.
- Deep cold kills batteries, thickens oil and exposes weak starters every winter.
- Engine block heaters, battery blankets and winter-grade oil are standard equipment, not options.

+ 05 Questions
Juneau battery questions
How long does a car battery last in Juneau?
Three to five years is typical. Deep cold doesn't age a battery the way heat does, but it punishes any battery that's weak or undercharged, so keeping it fully charged matters most.
Should I use a battery warmer?
In deep cold, yes. A battery blanket or pad keeps the battery warm enough to deliver its cranking power, and it plugs in on the same cord as the block heater.
Can a car battery freeze?
A fully charged battery is very resistant to freezing, but a discharged one can freeze at temperatures that are common here, and the ice can crack the case. A battery that has frozen has to be replaced.
Do you bring the battery to me in Juneau?
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 Juneau 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 Juneau?
If the test points to the alternator, starter or anything else, Mobile Auto Repair sends a mobile mechanic to Juneau for the repair.
