- Battery Charging Basics: Your alternator recharges the battery while the engine runs. Typically, a battery will recharge within 30 minutes to an hour of driving.
- Battery Health Check: Since your battery dropped to 11 volts, it's good to check its overall health. It's not uncommon for batteries to recover from such a state, but repeated deep discharges can shorten their lifespan.
- Precautions During the Drive: To ensure optimal charging, avoid using unnecessary electrical accessories like the stereo or air conditioning more than needed.
- Post-Drive Check: After your drive, consider using a multimeter to check the battery voltage. A healthy battery should read around 12.6 volts when fully charged.
- For Your Ferry Trip: Given the duration of your ferry trip, your battery should hold its charge. However, it's wise to carry jumper cables as a precaution.
- Avoiding Overstress: Remember, a severely weakened battery can strain the alternator. If you have any doubts about your battery’s condition, getting it tested at a garage is a good idea.
- Final Thoughts: If your battery is relatively new and hasn't been deeply discharged often, it's likely to recover well from this incident.
