Ever since the average car became a \u2018rolling computer\u2019, car battery related breakdowns skyrocketed (obviously).<\/p>\n\n\n\n

Nowadays, cars are equipped with over 30 different control modules that are constantly exchanging information with each other, therefore a healthy and powerful battery is extremely important.<\/p>\n\n\n\n

How to Choose the Best Battery for Mazda 3<\/strong><\/h2>\n\n\n\n

Before we dive in, let\u2019s take a look at what you should look for when buying a battery for your Mazda 3. Remember, each car is different, therefore different cars need different size, type and capacity batteries.<\/p>\n\n\n\n

Battery Group Size (BCI)<\/strong><\/h3>\n\n\n\n

Different engine bays can only fit a certain size battery, therefore engineers had to come up with a way to categorize batteries by their size. Make that sure the size of your battery of choice is as close to your car\u2019s OEM battery as possible. That way, you won\u2019t face any problems when installing the new battery.<\/p>\n\n\n\n

Here is the BCI group size chart in imperial and metric:<\/p>\n\n\n\n\n\n\n\t\n\n\t\n\t\n\t\n\t\n\t\n\t\n\t

Cold Cranking Amps (CCA)<\/strong><\/h3>\n\n\n\n

Cold Cranking Amps<\/a> is the single most important metric for cold weather. It\u2019s a measure of the discharge load in amperes that a battery in 0o<\/sup>F temperature can deliver for 30 seconds, while still maintaining terminal voltage to or higher than 1.20V per cell. To put it simply, the higher the CCA, the better the batter will perform in cold weather.<\/p>\n\n\n\n

Reserve Capacity (RC)<\/strong><\/h3>\n\n\n\n

RC is the number of minutes a fully charged battery will discharge constant 25 amps until the battery voltage drops below 10.5 Volts. This is supposed to simulate a complete charging system failure, meaning that only the reserve power on the battery is powering all electrical demands of the car. Similarly to CCA, the higher the Reserve Capacity, the better.<\/p>\n\n\n\n

Ampere Hour (Ah)<\/strong><\/h3>\n\n\n\n

Ampere hour is how you measure the flow of energy in amperes over one hour. For example, a 60Ah battery (the most common for Mazda 3), can supply 1 amp of current for 60 hours before it dies. Just like the ratings above, the higher the ampere hour rating of a battery, the better.<\/p>\n\n\n\n

EFB vs AGM for i-stop<\/strong><\/h3>\n\n\n\n

Now, changing your car\u2019s battery when it\u2019s going bad is easy, however, it becomes a headache once your car comes with a start-stop function and needs a special (and very expensive) battery. Unfortunately, this is the case with some Mazda 3’s.<\/p>\n\n\n\n

Some of these Japanese beauties run a special Q85 EFB battery, in this case, EFB stands for Enhanced Flooded Lead-Acid Battery. The Q85 EFB was specially designed to work with the i-stop function as it introduced frequent charging and discharging cycles.<\/p>\n\n\n\n

However, you don\u2019t need to spend a fortune on a new Q85 battery. Even though the original OEM Q85 is still the recommended replacement, there are plenty of much cheaper and better-performing alternatives for cars with start-stop functions on the market right now.<\/p>\n\n\n\n

Of course, EFB performs better than a conventional lead-acid battery, but as long as you get an AGM (Absorbed Glass Mat) battery, your Mazda\u2019s electrical system should work just as well or even better. An AGM battery is a better-performing, maintenance-free upgrade to the EFB.<\/p>\n\n\n\n

Enough with the technical mumbo-jumbo, let\u2019s get your Mazda 3 back on the streets. <\/p>\n\n\n\n
