It’s also essential to consult your owner’s manual for specific instructions on changing the battery. Some Subaru Outback models may have unique requirements or precautions to take.
Choosing the Right Battery
When selecting a new battery, make sure it’s compatible with your Subaru Outback. Check the battery’s voltage, cold cranking amps (CCA), and reserve capacity (RC). The battery should have the same or higher specifications as the original battery.
Here are some key factors to consider when choosing a new battery:
- Voltage: Ensure the new battery has the same voltage as the original battery (12V for most Subaru Outback models)
- Cold Cranking Amps (CCA): Choose a battery with a higher CCA rating to ensure reliable starting in cold temperatures
- Reserve Capacity (RC): Select a battery with a higher RC rating to ensure the battery can handle short-term power surges
- Age: Opt for a new battery that’s less than a year old to ensure it’s still under warranty
Understanding Battery Terminology
Battery terminology can be confusing, but it’s essential to understand the basics. Here’s a quick rundown of key terms:
| Term | Definition |
|---|---|
| Voltage | The electrical potential difference between two points in a circuit |
| Cold Cranking Amps (CCA) | The battery’s ability to supply a high current to the starter motor in cold temperatures |
| Reserve Capacity (RC) | The battery’s ability to supply power to the electrical system during short-term power surges |
