The 2017 Hyundai Accent uses a standard 12-volt automotive lead-acid battery. It powers starting and electrical systems, and there is no high-voltage battery in this non-hybrid model.
Battery type and what it does
The Accent relies on a conventional 12-volt battery to start the engine, run lights, and power accessories when the engine is off. In most markets, the battery is a maintenance-free flooded lead-acid type; it is sealed and vented to the atmosphere. Hyundai did not equip the 2017 Accent with a hybrid or plug-in system in that year, so there is no hybrid battery to consider.
What to know about its size and compatibility
- Battery type: 12-volt automotive lead-acid battery (not lithium-ion). In most trims it is a standard flooded or maintenance-free lead-acid type.
- Group size and rating: The exact group size and cold-cranking amps (CCA) depend on market and trim; the information is printed on the battery label and listed in the owner's manual. Have the store verify the correct size using your VIN or the owner's manual.
- Location and fit: Located in the engine bay; ensure the replacement fits in the battery tray and bracket with compatible terminal orientation.
Summary: The 2017 Accent uses a common 12-volt lead-acid battery; verify the exact group size and CCA on the existing battery or in the manual when replacing.
How to identify the exact battery you have
To ensure you buy the right replacement, check the label on the current battery and the owner's manual:
- Read the battery group size (for example, a number like 24, 35, 42, or 44R on the label).
- Note the cold-cranking amps (CCA) and reserve capacity (RC) ratings.
- Check the terminal layout and dimensions to confirm mounting and cable fit.
- Use your vehicle identification number (VIN) when shopping at an auto parts store to confirm compatibility.
Conclusion: The exact specs will guide your replacement; always match the group size, rating, and terminal arrangement to the original.
Replacing the battery: quick guide
If you’re replacing the battery yourself, follow these standard steps and safety precautions:
- Disconnect the negative (-) terminal first, then the positive (+) terminal; remove the hold-down bracket. Wear eye protection and gloves.
- Remove the old battery, clean the tray and terminals, and inspect for corrosion or damaged cables.
- Install the new battery with the correct polarity, secure the hold-down, and connect the positive terminal first, then the negative terminal.
- Check that the electrical systems function and recycle the old battery at an approved facility.
Note: If you’re not comfortable performing a DIY battery replacement, have a professional technician handle it to ensure safe disposal and correct reconnection.
Summary
The 2017 Hyundai Accent uses a conventional 12-volt lead-acid automotive battery, with no hybrid-high-voltage pack in that year. Replacement requires matching the exact group size and ratings as listed on the battery label or in the owner's manual, and proper safety procedures should be followed when replacing it.
