2015–2019 Hyundai Sonata Battery Size (BCI Group and CCA)

Which Hyundai Sonata model years does this cover?

These battery specifications apply to every Hyundai Sonata built from 2015 through 2019 — the LF (7th generation), mid-size sedan. 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 2015–2019 Hyundai Sonata

• 2015Generation launch on the LF platform; Eco 1.6T added
• 2016Hybrid and Plug-in Hybrid trims join the lineup with the Nu 2.0L GDI hybrid powertrain
• 2018Mid-cycle facelift arrives; a new mid-range SEL trim is added with Blue Link telematics, SiriusXM, HD Radio, and a power driver's seat standard (base SE and Eco lose those items as standard equipment)
• 2018–2019Mid-cycle facelift: new front/rear styling, revised interior with digital instrument cluster option, Eco 1.6T dropped from some markets late in the run
• 2019Final model year of the LF generation; facelifted trim lineup and styling carry over unchanged ahead of the all-new DN8 for 2020

What size battery does a 2015–2019 Hyundai Sonata take?

BCI group 94R (AGM, idle-stop-equipped trims) / 124R (flooded, non-ISG trims). 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.

Does the 2015–2019 Hyundai Sonata 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 2015–2019 Hyundai Sonata?

Engine bay, driver side.

Does a 2015–2019 Hyundai Sonata need the battery registered after replacement?

Trims with Idle Stop & Go (some Eco 1.6T configurations) require an AGM battery; other trims use a conventional flooded battery. Confirm which your trim needs before replacing. Installing flooded on an ISG car will fail prematurely.
