Complete Mazda 3 Battery Replacement Guide Phuket

The Mazda 3 is a highly popular compact car with beautiful design, fun driving dynamics, and advanced SkyActiv technology. However, many people may not know that each Mazda 3 generation uses different batteries. Especially the BP generation (2019+) which has the i-Stop system installed as standard, requiring EFB batteries only.

I’ve encountered many customers who installed standard batteries in their newer Mazda 3, only to have them fail within 2-3 months because the i-Stop system works very frequently. This article will explain everything about Mazda 3 batteries in the simplest way possible.


Mazda 3 Generations and Battery Types

Mazda 3 has 3 main generations sold in Thailand, each using different batteries:

BL Generation (2009-2013):

  • No i-Stop yet
  • Uses standard 55D23L battery
  • Price: ฿2,200-2,800

BM Generation (2014-2018):

  • Some models have i-Stop
  • Uses 55D23L (non-i-Stop models) or Q85 EFB (i-Stop models)
  • Price: ฿2,200-3,800 depending on variant

BP Generation (2019-Present):

  • i-Stop in all variants
  • Must use Q85 EFB only
  • Price: ฿3,200-4,500

Why Mazda 3 BP Generation Must Use EFB Battery

Mazda 3 from the BP generation (2019 onwards) has the i-Stop system installed as standard in all variants, whether C, S, SP, SP Sport, or X models.

The i-Stop system automatically turns off the engine when stationary and restarts it when the driver releases the brake. It works similarly to Toyota/Honda’s Start-Stop, but with a special feature: Mazda uses a faster starting system, making it start more frequently than other brands.

This is why Mazda 3 BP generation must use EFB batteries only. Standard batteries are strictly prohibited.


How to Check if Your Mazda 3 Has i-Stop

Check by Year:

  • 2013 and below = No i-Stop
  • 2014-2018 = Some models have i-Stop (check variant)
  • 2019 and above = Has i-Stop in all variants

Check Dashboard:

  • “i-Stop OFF” button = Has i-Stop system
  • Green i-Stop light when stopped = Has system

Check Owner’s Manual:

  • Clearly states i-Stop is included

If unsure, send a dashboard photo and I’ll check for you.

  • GS 55D23L: ฿2,400
