Car Battery Buying Tips for Choosing the Right Replacement
Car batteries do not last forever, so vehicle owners should plan ahead.
Have the battery checked every year, especially before a long trip.
A mechanic should load-test it annually after it reaches two years old in a warm climate.
In a cold climate, testing can begin after four years.
Batteries come in different sizes, so the replacement must fit the car.
The same brand or model that worked before may not always be the best choice.
New batteries should be as fresh as possible because they lose strength while stored.
Check the warranty and return the old battery when buying a replacement.
Have the battery inspected annually, especially before a long road trip.
Load-test batteries annually after two years in warm climates or four years in cold climates.
Choose a battery that fits both your vehicle and driving needs, rather than relying only on brand or model.
Buy a fresh battery—less than six months old, and preferably about three months old.
Compare free-replacement and prorated warranties, and return the old battery for any refundable deposit.
