Multiple protections: Reverse, Overheating,Low voltage,Short circuit,Over current protection.
Intelligent:Shorter charging time due to optimized charging process.
Optimization:Stabilizes internal battery chemistry for increased performance and longevity.
Energy-saving:When the battery is fully charged,it will automatic stop.
Differnt Voltage Standard:The voltage standard is different when on automatic and manual charge. The automatic charge is about 14.3v,manual charge is about 14.8v. So there will show two different readings when you change the charging ways. Please notice DO NOT charge the battery for long time
