What Size Battery Is in the 2019 Hyundai Elantra?

The 2019 Hyundai Elantra typically uses a 12‑volt lead‑acid battery in the Group 47 (H5) size, with around 60–70 amp‑hours (Ah) and roughly 600–760 cold cranking amps (CCA), though exact specs vary slightly by trim and replacement brand.

Understanding the 2019 Hyundai Elantra’s Battery Specifications

The 2019 Hyundai Elantra is equipped from the factory with a conventional 12‑volt lead‑acid battery that powers the starter motor, electronics, lights, infotainment, and safety systems. While many owners simply refer to this as a “car battery,” it has specific size and performance ratings that matter when it comes time for replacement.

Factory Battery Group Size

In North America, the 2019 Elantra most commonly uses a Battery Council International (BCI) Group 47 battery, also known as H5 in European sizing. This size defines the battery’s physical dimensions, terminal layout, and hold‑down compatibility with the car’s battery tray.

The main physical attributes of the Group 47 (H5) battery used in the 2019 Elantra can be summarized in the following list to show what “size” means beyond a simple label.

• Group size: BCI Group 47 (also labeled H5, L2 by some brands)
• Approximate dimensions: about 9.6 in (244 mm) long, 6.9 in (175 mm) wide, 7.5 in (190 mm) high
• Terminal type: Standard top‑post automotive terminals
• Polarity: Typically positive terminal on the right (check your original battery to confirm)

Together, these characteristics ensure the battery physically fits in the Elantra’s engine bay, aligns with the cables, and can be securely clamped in place as designed by Hyundai.

Electrical Ratings: CCA and Capacity

Beyond physical form factor, the battery’s performance is defined by cold cranking amps (CCA) and amp‑hour (Ah) capacity. Hyundai’s original equipment battery for the 2019 Elantra falls into a common range used by most aftermarket brands for this model.

The following list details the typical electrical specifications you’ll see when shopping for a 2019 Elantra replacement battery, helping you recognize whether a given product meets or exceeds factory standards.

• Voltage: 12 V (standard for gasoline passenger vehicles)
• Cold Cranking Amps (CCA): generally around 600–760 CCA, depending on brand and model line
• Amp‑hour rating (Ah): typically around 60–70 Ah for Group 47 batteries used in compact sedans
• Reserve capacity (RC): often in the 100–130 minute range (amount of time battery can run a 25‑amp load before dropping below a specified voltage)

These ratings indicate that while the Elantra’s battery is compact, it has enough power to reliably crank the engine in a range of climates and to support modern electronic features when the alternator is not charging at full output.

Variations by Trim Level and Market

While Group 47 is the standard fitment for most 2019 Hyundai Elantra models sold in the U.S. and Canada, there can be minor variations depending on trim, options, and region. However, the overall battery “size class” remains consistent, with differences mainly in brand, exact CCA rating, or internal construction.

Gasoline Models and Trims

The 2019 Elantra lineup includes several trims—such as SE, SEL, Value Edition, Limited, Eco, Sport, and others—primarily with 2.0‑liter or 1.4‑liter turbo gasoline engines. From a 12‑volt battery standpoint, they largely share the same Group 47 footprint and similar electrical specs.

The following list outlines how trim differences typically affect the battery only in subtle ways, rather than requiring a different size.

• Base trims (e.g., SE, SEL): Usually equipped with a standard flooded lead‑acid Group 47 battery with moderate CCA.
• Higher trims (e.g., Limited, Sport): May come with slightly higher CCA ratings to support more electrical features but remain in the same group size.
• Eco or turbo models: Often still use the same Group 47 size, with similar or slightly uprated CCA for reliable cold starts.
• No factory hybrid/EV version: The 2019 Elantra in most markets does not include a full hybrid or electric variant, so there is no separate high‑voltage traction battery to consider.

In practice, most owners across trims can replace the battery with any reputable Group 47 unit meeting or exceeding the original CCA rating, without worrying about trim‑specific part numbers beyond minor differences in OE branding.

Regional Differences

Outside North America, Hyundai sometimes uses slightly different battery coding conventions, and local suppliers may list batteries by European codes (like H5 or L2) instead of BCI Group 47. The physical and electrical characteristics, however, remain functionally equivalent.

The list below highlights what tends to change by market and what remains constant, helping international owners match the correct battery even if part labels differ from U.S. standards.

• Labeling: European or Asian markets may label the battery H5, L2, or provide EN standards for CCA instead of SAE.
• CCA measurement standard: EN (Europe) vs. SAE (North America), with figures that may look different but represent comparable performance.
• Branding: Local battery manufacturers may supply Hyundai’s OE batteries instead of multinational brands.
• Size consistency: The physical dimensions and general 12‑volt design stay within the Group 47/H5 class.

Thus, regardless of regional labeling quirks, owners should look for a battery whose physical size matches Group 47/H5 dimensions and whose CCA rating is in the same performance range as the factory unit.

Replacement Considerations for 2019 Elantra Owners

When it’s time to replace the battery in a 2019 Hyundai Elantra, selecting the correct size is only part of the equation. Quality, warranty coverage, and type of battery construction also factor into long‑term reliability and cost.

Choosing the Right Replacement Type

Most 2019 Elantras come with a conventional flooded lead‑acid battery, but many aftermarket options are also available in enhanced types such as AGM (Absorbent Glass Mat). Both types are sold in the Group 47 size, giving owners flexibility to upgrade if desired.

The following list compares the main battery types Elantra owners will encounter, helping clarify which might be best suited to individual driving patterns and climates.

• Standard flooded lead‑acid (most common): Typically the least expensive; sufficient for normal driving and moderate climates.
• AGM (Absorbent Glass Mat): More resistant to vibration, better for high‑demand electrical usage and frequent short trips; often higher CCA and longer life but more expensive.
• “Maintenance free” labeled batteries: Sealed designs that don’t require topping off water; this is the norm for modern batteries and matches OE style.
• Premium/high‑output variants: Offer higher CCA and reserve capacity within the same Group 47 footprint, useful in very cold climates or for heavy accessory use.

While Hyundai does not require an AGM battery for the 2019 Elantra, choosing an AGM or higher‑spec Group 47 unit can provide extra starting margin and durability, especially if the vehicle sees harsh conditions or a lot of stop‑and‑go city driving.

Verifying Fitment and Installation Details

Before purchasing a new battery, it is wise to double‑check fitment against the specific Elantra configuration. Online fitment tools are generally reliable, but they should be confirmed with the vehicle’s existing battery label and the car’s manual.

The next list outlines the basic steps and checks owners should perform to ensure compatibility and a smooth installation, whether they change the battery themselves or use a professional service.

• Confirm group size: Match the new battery to Group 47/H5 dimensions; avoid trying to fit non‑standard sizes that may not secure properly.
• Check terminal orientation: Make sure positive and negative posts match the layout of the original battery to prevent cable reach issues.
• Compare CCA rating: Choose equal or higher CCA than the factory battery, especially in cold climates.
• Inspect hold‑down and tray: Ensure the new battery seats fully and can be clamped tightly to prevent movement.
• Protect vehicle electronics: If possible, use a memory saver or follow the owner’s manual instructions to avoid losing radio presets or triggering warning lights during replacement.

If all of these factors are checked carefully, the new battery should deliver reliable performance and integrate seamlessly with the Elantra’s electrical system without fitment or starting issues.

Summary

The 2019 Hyundai Elantra uses a standard 12‑volt automotive battery, most commonly specified as BCI Group 47 (also labeled H5), with typical ratings around 60–70 Ah and roughly 600–760 CCA. This size defines both the physical form factor and the performance level expected by Hyundai’s engineers. While trims and markets can introduce minor variations in brand and labeling, the underlying battery class remains consistent. For owners, the key points are to choose a Group 47/H5 battery with equal or higher CCA than the original, ensure correct terminal orientation and secure mounting, and consider premium or AGM options if added durability or cold‑weather performance is desired.
