The XTAR VC2 charger is the World's first lithium-ion battery charger that features an innovative tachometer-style LCD display screen. This charger will tell you the real power of your battery! The VC2 will display the batteries mAh capacity assuming it is completely drained before charging. Like all of our chargers, it can intelligently identify input power and automatically adjust the the most suitable charge current (0.15A~0.5). It is compatible with both IMR lithium batteries and small capacity batteries. Both channels are independent and it can also tell you if you have bad batteries. And like all XTAR chargers, the VC2 features overcharge protection, over-discharge, short-circuit, and reverse polarity protection. Adopted from the VP2 charger, the VC2 can revive overly discharged batteries as well.
