A replacement 12-volt battery for a 2019 Acura ILX typically costs between about $100 and $350, depending on the battery type and where you buy it, with installation extra.
Key specifications for the ILX battery
Understanding the correct size and chemistry helps you shop with confidence. The ILX uses a 12-volt battery located in the engine bay, with a common group size of 51R. OEM replacements are usually maintenance-free flooded batteries, though AGM (absorbed glass mat) options are available from some retailers for enhanced performance. Always verify the exact size, CCA (cold-cranking amps), and RC (reserve capacity) on the label or in the owner's manual before purchasing.
Group size and compatibility
Most 2019 ILX models use group size 51R (12V). Ensure the CCA and RC meet or exceed the OEM specifications by checking the battery label or owner's manual.
Battery types you may encounter
You can choose between standard flooded maintenance-free batteries and AGM batteries. AGM options tend to cost more but offer better starting performance in cold weather and longer life, which can be beneficial for frequent short trips or heavy electrical loads.
Cost by source
Prices vary by where you buy and the battery type. Here are typical ranges you can expect for a 2019 ILX replacement.

- Aftermarket standard flooded battery: roughly $100–$180.
- AGM/high-performance battery: roughly $180–$300.

Where to buy and installation options
Choosing where to buy affects price, warranty, and convenience. Common options include:
- Acura/Honda dealership for OEM or recommended replacements, often with installation and warranty.
- Auto parts chains (AutoZone, Advance Auto Parts, O'Reilly, NAPA) offering standard and AGM batteries with in-store installation.
- Online retailers and marketplaces that ship batteries or offer local pickup; installation may be available separately or bundled.
- Mobile battery replacement services that come to your home or office.
- DIY installation if you have the proper tools and safety precautions; disconnect the negative terminal first and follow proper procedure.
When choosing a source, compare warranties (2–4 years standard; longer for AGM options), return policies, core charges, and whether installation is included or separate.
