Question about 2011 Mazda 2 1.6
My Mom has a 2011 Mazda 2. She bought it new, and in cold weather the car won't start. The dealership said it was the battery, so she replaced it and it died again a few months later. She replaced it a third time and it was fine in the warm weather, but now that cold weather has hit in Upstate New York, she went out to get groceries the other day... car won't start/dead battery. Is it REALLY the battery, or something else?

When that light comes on, it is indicating charging system problem which could mean alternator not charging for one reason or another like loose belt, faulty alternator, or yes, bad battery or connection at battery, for example. First & easiest thing to do is check all your connections to battery, which you've probably done, and make sure they're tight & clean. Make sure belt driving alternator is good & tight, and in good shape. Now boost the vehicle to get it going & test voltage at battery, after you take cables off. My guess is in your case, the voltage will begin to go down, indicating a bad alternator, that will need to be replaced.

It's fine to use a battery with a higher cold crank rating than original. Consider the rating in the manual to be a minimum requirement. You'll be fine as long as the physical dimensions and terminal placement are compatible with your car. The battery manufacturer's guide should tell you which battery fits your car.

Was this mechcanic certified? It sounds like your altenator has a weak diode or regulator instead if the car does start every day. To see if you have a bad diode take a volt meter and set it to the DC switch for direct current. Have the red probe to red (POSITIVE) and black on black (NEGATIVE) It sould give you a reading of 13.5 volts when the engine is running. If not switch the red wire from the meter to the black (Negagtive) on the batteryand the black wire from the volt meter to the red (Positive) to the battery. If you get the same reading when inverting the wires you have a bad diode. A diode only lets current flow one direction. If it shows flowing both ways it will under charge your battery causing it to die out

Testimonial: "You asked me if it was mechanic certified? What does that mean? I don't have a voltage meter at home. Is Dealership responsible for this? Thanks"
