A replacement battery for an Acura TSX typically costs roughly between $100 and $350, depending on the type and retailer, with OEM or AGM options at the higher end. Installation and core charges can add to the total.
This article breaks down the price ranges, explains what affects the cost, and offers practical guidance on choosing the right battery for your TSX. It also covers where to shop and what to expect in terms of warranties and installation.
Price ranges by battery type
Prices vary by battery type and retailer. The following ranges reflect common options available as of 2024–2026 and can differ by region and current promotions.
- Budget standard 12V lead-acid replacement battery (non- AGM): typically $100–$180
- AGM (Absorbent Glass Mat) battery: typically $180–$320
- OEM/Dealer replacement battery: typically $200–$380 (often similar in price to AGM, depending on supplier)
- Premium/high-output options with longer warranties or higher CCA: typically $300–$450
Note that core charges (often around $10–$25) may apply and installation fees can vary. Some retailers bundle installation with purchase, while others charge separately.
Choosing the right battery for your TSX
To ensure compatibility and value, you should verify the correct size and electrical requirements for your year and trim. The exact group size and required cold-cranking amps (CCA) can vary, so consult the owner's manual or inspect the current battery label.
- Check the vehicle’s manual or the current battery label for the recommended group size and minimum CCA.
- Compare the specifications (CCA, reserve capacity, and amp-hour rating) across options to meet your climate and driving needs.
- Decide between standard lead-acid and AGM. AGM batteries are more resistant to vibration and perform better in cold climates but cost more upfront.
- Review warranty terms and coverage length, including what is prorated and for how long.
Bottom line: choose a battery that matches your TSX’s electrical demands, terminal layout, and mounting fit, and factor in climate and driving patterns when selecting AGM vs. standard.
Where to buy and what to expect
Shopping around can affect price, warranty, and installation options. Here are common avenues and what they typically offer as of 2024–2026.
- Automotive parts stores (e.g., AutoZone, Advance Auto Parts, O'Reilly) — wide selection, frequent promotions, and often free installation with purchase; core charge may apply
- dealership parts departments — OEM batteries, precise fit for your vehicle, typically higher upfront price
- Specialty battery shops or online retailers — may offer installation services, delivery, and competitive warranties
When shopping, ask about installation inclusion, confirm the core charge policy, and compare warranty terms (length, coverage scope, and prorated vs. non-prorated).
Warranty and installation considerations
Warranty length and terms vary by brand and retailer. Common warranties range from 2–3 years for budget options to 4–5 years or more for AGM or premium batteries. Installation may be free or charged separately, and some places offer free recycling of the old battery.
Summary
For an Acura TSX, replacing the 12V battery typically costs between $100 and $350, depending on whether you choose a standard lead-acid, AGM, or OEM battery, plus any installation fees and core charges. Always verify the correct size and CCA for your year and trim, compare several sources, and consider warranty terms to maximize value and reliability.
