Heat Shortens Battery Life More Than Cold Does
Cold weather gets the blame for dead batteries, but sustained heat is what actually shortens their service life. High underhood temperatures accelerate the internal corrosion and fluid loss that eventually kill a battery, which is why batteries in the Phoenix area frequently need replacing sooner than the mileage or the warranty period would suggest.
Testing Beats Guessing
A battery that starts the car on a warm afternoon can still fail on the next cool morning, so we test battery condition rather than relying on age alone. We also check the charging system, because a failing alternator will destroy a new battery and a weak battery puts extra load on the alternator. Corroded terminals, a loose ground strap or a worn serpentine belt can produce symptoms that look like a bad battery, and all of them are far less expensive to fix. Our staff includes ASE Master Certified Technicians certified in electrical and electronic systems.
