It should The cables between charger and battery should be kept as short as possible to prevent excessive voltage drop (suggested cable length: 50cm~100cm). Too much voltage drop will lead to longer charging period.
Charger should be in the OFF mode before making battery connection or For auto ranging. Please refer to the manual before using this function.
