Product description
- 0V start When the battery is exhausted due to long-term use, repair mode can be used to repair the battery, and charging can be started when the voltage is low.
- Intelligent Digital LED Display The LED screen displays the values of ambient temperature, voltage, current and remaining battery capacity. You can easily check the battery status.
- Safety This 40A car battery charger has multiple protection functions such as short circuit protection, overcurrent protection, cooling system and reverse polarity protection. The repair function activates batteries that have not been used for a long time, old batteries and batteries that cannot be charged.
- Note The battery charger will automatically turn off when fully charged. It starts charging when the battery is below a voltage level.
- The screen shows that 40A is the maximum current selected. Since this charger is a smart charger, it is normal for the charging current to fluctuate according to the different charging stages and battery power. This is to better maintain the battery life. For example, the current will gradually decrease when the first 15 minutes of charging is only 2.5A, or when the battery is more than 80% charged. Due to circuit loss, the actual maximum charging current is about 75%. The displayed current is only for the gear selection, not the real-time current.
