Charging Current Selection Look for a charger that offers multiple charging current options, such as 1A and 2A. This allows you to choose the appropriate charging rate based on your battery's capacity and condition.
Advanced Boost Charging Some chargers offer a boost or recovery mode that provides a higher voltage or amperage to help revive deeply discharged or sulfated batteries. This feature can be useful if you have an older or heavily discharged battery.
Auto-Cut-Off Function An auto-cutoff function is crucial as it prevents overcharging by automatically stopping the charging process when the battery reaches a certain voltage or is fully charged. This helps protect your battery from damage caused by overcharging.
