2013–2016 Mazda CX-5 Battery Size (BCI Group and CCA)

Which Mazda CX-5 model years does this cover?

These battery specifications apply to every Mazda CX-5 built from 2013 through 2016 — the KE (1st generation), compact suv. Nothing in this specification changes between those model years. Pick your year for the engines it offered, what changed that year, and the problems recorded against it.

What changed during the 2013–2016 Mazda CX-5

• 2013US launch; 2.0L only at first, 6-speed manual or automatic, FWD or AWD
• 20142.5L SkyActiv-G added on Touring/Grand Touring; 2.0L remains standard on Sport
• 2016Facelift (styling, chassis stiffening, updated i-Activsense safety suite); mechanical specs (oil, filters, wipers) carry over unchanged

What size battery does a 2013–2016 Mazda CX-5 take?

BCI group 35, rated at 520 cold cranking amps from the factory. Group size is a physical dimension and terminal-position standard, so a battery from a different group may not clamp down or may put the terminals on the wrong side.

How many CCA does a 2013–2016 Mazda CX-5 need?

At least 520 CCA. Going higher is harmless and helps in cold climates; going lower is how a vehicle that started fine in October stops starting in January.

Does the 2013–2016 Mazda CX-5 need an AGM battery?

The factory battery is a conventional flooded type. AGM is a valid upgrade, but never downgrade from AGM to flooded.

Where is the battery on a 2013–2016 Mazda CX-5?

Engine bay, driver side.

Does a 2013–2016 Mazda CX-5 need the battery registered after replacement?

Factory battery is a flooded Group 35, commonly rated ~500–650 CCA depending on supplier (Mazda's own spec sheet lists it by amp-hour: 12V-60Ah/20HR, roughly equivalent). The CX-5 has no battery-management electronics that require AGM, so a higher-CCA flooded or AGM Group 35 both work as replacements.
