This is a very, very common issue.
There are two parts to a car battery,
The first part is common to all vehicles, they are 12 volt batteries. The 12 volts are standard for all of the electrical equipment on the vehicle. ( headlights, stereo, brake lights, etc )
The second part is the amps, also refered to as, " cold craking amps ", it is the amps that start your engine, not the 12 volts.
Two batteries, side by side, identical in every way except one has 500 cold craking amps, and the other has 700 cold cranking amps.
The 550 cranking amps may start a 4 cylinder engine, but it's very unlikely that it's powerful enough to start a 6 cylinder engine, especially if it's cold outside. However, the 700 cranking amps should start a 6 cylinder with out any problems.
You very likely have a battery that doesn't meet the vehicles, " minimum cold cranking amps requirement ."
I am sorry for the long explaination, but, many people are having the same issues, and because this is likely going to be viewed by other users I am hoping that they will start looking more at the " cold cranking amps " rating, before thay buy a battery that isn't powerful enough to start their car, especially in cold weather.
I hope this helps you.
