How To Choose The Best Battery For Mazda 3?


Which factors determine the effectiveness of a Mazda 3 battery? We have already hand-picked 10 items for you. But, if you need to decide on your own, you would have to know what particular aspects you should contemplate for making the perfect decision. 

Here are the things you need to keep in mind:

Battery Group Size


Not all car engines are the same in size, so car batteries also differ in that regard. A battery intended for a particular engine size won’t fit in a different one. Even if it does, the fit won’t be satisfactory. So, getting the size right is car battery shopping 101. Mazda 3 engines use category 35 batteries, so make sure you are buying a size 35 battery.

Cold Cranking Amps


Cold Cranking Amps, or CCA, won’t come into play unless the weather turns freezing cold. It represents the magnitude of discharge load a battery can provide for half a minute in 0 degree Fahrenheit temperature while sustaining a minimum terminal voltage of 1.2 volts. In simpler words, higher CCA ratings imply better engine performance in winter.

Reserve Capacity


Reserve capacity, also known as reserve minutes, is the amount of time a battery can maintain a load of 25 amperes before draining out of charge. The reserve capacity of a battery indicates the battery’s capacity to power a car’s electronic amenities. Therefore, a higher reserve capacity is desirable.

Frequently Asked Questions


Q. Will buying a non-OEM battery replacement harm my Mazda 3 engine?

No, you can buy any battery that fits the OEM specs. Mazda batteries are 12-volt ones that can provide a continuous power supply of 3 amperes over 20 hours. In terms of size, Mazda 3 batteries are classified as category 35 batteries. Any battery that fits these descriptions should be okay for Mazda 3 vehicle. 

Q. Will a bigger battery impact my Mazda 3’s performance?


Even though Mazda 3 engines originally use size 35 engines, getting a slightly bigger engine size won’t hurt. On the contrary, it could prolong the lifespan of your alternator. A bigger battery would act as a cushion between the engine and the alternator. It would also minimize the workload of the alternator. 

Final Say


A faulty battery is a common culprit for car accidents. If you notice your Mazda 3 engine acting up lately, check it and see whether or not you need a new battery. If you do need a battery replacement, make sure you buy the best battery for Mazda 3 to enjoy a seamless driving experience.
