1. Check Your Owner’s Manual

Your vehicle manual will specify the correct size, voltage, and amp-hour (Ah) rating for your car. Stick to these specs.

2. Match the Battery Size

Battery group sizes (like 24, 35, 48, etc.) determine the physical dimensions and terminal placement. Use the group size recommended for your car to ensure it fits and connects properly.

3. Consider Battery Type

• Lead-Acid (Wet Cell): Cheaper, but needs occasional maintenance.
• AGM (Absorbent Glass Mat): More expensive but lasts longer, handles extreme temperatures, and is maintenance-free — ideal for modern cars with high electronic demand.

4. Check the Cold Cranking Amps (CCA)

CCA is vital if you live in colder climates. It measures how well the battery starts your engine in cold temperatures. Match or exceed the manufacturer’s CCA recommendation.

5. Look at Reserve Capacity (RC)

RC indicates how long the battery can run essential systems if the alternator fails. A higher RC is generally better for backup reliability.

6. Buy Fresh

Check the manufacture date — batteries lose charge over time. Choose one that’s less than 6 months old. Battery codes like A5 (January 2025) tell the age.

7. Warranty Matters

Look for a good free replacement period and prorated warranty. A 1–2 year full replacement is ideal.]

8. Compare Brands and Reviews

Stick to reputable brands (like Exide, Varta, Bosch, Optima, etc.) and read local reviews or ask your mechanic for advice.

9. Don’t Overspend

More expensive doesn’t always mean better. Just make sure the battery meets OEM specs and your usage needs.

10. Get It Professionally Installed (If Unsure)

While some batteries are easy to replace, many modern vehicles have tight engine bays or electronics that may require coded resets. If you’re not confident, let a professional handle the installation to avoid damage or system errors.
