how to charge a deep cycle
marine battery.
When charging deep cycle marine batteries, complete discharge should be avoided and charged and discharged within the middle range of battery capacity (50-85%) to extend battery life. When charging, it is necessary to ensure that the positive and negative poles of the charger correspond correctly to the positive and negative poles of the battery, that is, the positive pole is charged to the positive pole, and the negative pole is charged to the negative pole to avoid dangerous consequences
In addition, the battery system should be equipped with sufficient capacity charging devices and measures to suppress radio interference. The charging device should be equipped with overcurrent protection, including short circuit protection, as well as instruments that can indicate charging and discharging current, voltage, temperature, and other parameters on or near the charging device or in frequently manned areas on the ship. The charging device of the battery system should have an interface with the Battery Management System (BMS) and operate under the conditions specified by the BMS. The charging device should also be equipped with a temperature monitoring device to transmit corresponding signals to the charging control system based on temperature changes, achieving temperature monitoring and overheating protection functions at the charging gun end
Although batteries may be fully charged at lower voltages, they require longer periods of time, so it is important to ensure that the battery does not experience long-term undercharging
