But even at best, a healthy battery in 80 degree weather

remember that a battery is rated by cold cranking
amps (CCA), indicating its power and the reserve capacity
rating (RC), which indicates how long your car's accessories
can run and still have enough power to start the engine.
a car in cold weather can take up to twice as much
current to turn over a cold engine, cars in colder
climates would benefit from a higher CCA rating. CHeck
your owner's manual for the original equipment manufacturer's
(OEM) minimum requirements needed for your car and
select the battery adequate for your needs. BUying
one with an excessive CCA rating may be a waste of
In every situation,
more RC (reserve) is better, like a little extra in
the checking account. THe size and number of plates
in a battery determine how many amps it can deliver.
By having more and/or larger plates, you can increase

connect the cables to the battery) and terminal polarity.
BCI and the battery manufacturers offer application
guidelines that contain the OEM cranking amperage
requirements and group number replacement recommendations
by make, model and year of car and battery size, CCA
and RC specifications.
