XTAR MC2 is a professional portable intelligent lithium-ion baery
charger with two slots charging independently. It’s compable with
14500/14650/16340/17500/17670/ 18350/18500 /18650/18700/
26650 3.6V/3.7V rechargeable Li-ion baeries.
With a three-stage charge algorithm, 0V acvaon of baeries, and
real-me detecon of baery state, MC2 charges baeries
intelligently and safely. Meanwhile, the built-in reverse-polarity and
short-circuit protecon are great insurance for safely charging.
M C2 charger applies to all kinds of Micro USB interface for power
supply. The funcon of intelligently idenfying input power and
automacally shiing charge current creates more convenience
and flexibility for charging.
With over-heat protecon funcon, when operate in high
temperature, MC2 will automacally lower charge current to
prevent over-heang burns. In addion, MC2 adopts so start
funcon to avoid damage from surge charge current.
MC2 has under voltage lockout and self-start funcon.

USAGE
M C2 is compatible with two 14500/14650/16340/17500/17670/
18350/18500/18650/18700 and one 26650 3.6V/3.7V rechargeable
lithium-ion batteries. Attempting to charge other battery types may
be hazardous, and can damage the batteries and charger.
Connect the adaptor (5V/1A) to MC2, indicators turn green, MC2
performs standby mode.
When MC2 is in standby mode, insert over discharged battery(
battery voltage≤around 2.0V) into the channel properly, MC2
shifts to activated state. When battery recovery finished, battery
starts being charged.
MC2 can intelligently identify the input power and automatically
adjust the charge current:
When input power is 5VDC/1.0A, the constant charge current
would be 500mA.
When input power is 5VDC/0.5A with two batteries
simultaneously charging, the current through both channels would
be 250mA, while with only one battery being charged, the charge
current would be 500mA.

When complete charging, indicators are green on. It’s
recommended to remove the batteries after batteries being
fully charged.
TIPS
Because of different baery types, capacies, and over-
discharge depths, the baery-revive me may vary; heavily
over-discharged baeries may not be able to be revived.
When charge baery with voltage higher than 4.0V, please
insert the baery into slot first, then connect the adaptor.
When charging completed, MC2 will stop supplying power to
the baeries, it’s recommended to remove the baeries.
When system detects the baeries’ voltage is lower than
4.1V, MC2 will automacally restart charging if baeries are
le in slots for a long me aer charge complete.

NOTICE
Please charge compatible batteries with MC2. Attempting to charge
other battery types may be hazardous, and can damage the batteries
and charger.
M C2 has integrated short-circuit protection to protect the charger if a
short circuit occurs in a battery. Note that this short-circuit protection
protects the charger; it does not prevent batteries from short-
circuiting internally.
When in standby mode, if the channel is of short circuit, the
indicator would be red on. It will do no harm to the charger.
Keep MC2 away from water and excessive dust.
Do not disassemble MC2. Damage may result.
Do not operate the charger if it appears damaged in any way.
