A battery charger that is appropriate for the boat's battery system will greatly extend the life of the batteries.
A battery charger must respect the following characteristics:
- Three-phase charging curve (boost, absorption, floating), except for lithium batteries.
- Selection of the battery technology.
- If you are sailing in areas where the temperature is far below 25°C, in addition to the above criteria, you should make sure that the battery charger takes the temperature into account.
