Tips for choosing a Group 51R
- Group size sets the case size and terminal layout (our diagram doesn't show the terminal side yet). It doesn't set power, so check CCA too.
- Equal or higher CCA than the minimum is fine. Lower can mean hard starts in cold weather.
- If your car came with an AGM or EFB battery (often cars with engine start-stop), stay with that type.
