Tips for choosing a Group H8 (49)

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.
