diagrams located on the charger.

Do not allow the unit to be exposed to direct sunlight. Operate in
well-ventilated area. Do not place unit on the carpet.

Do not allow the battery terminals to become shorted.

What is 0.1C, 0.2C, etc?

“C” stands for the battery capacity and the number in front of it is the
fraction of the battery capacity. For example, 0.1C means 0.1 times the
capacity for the battery. For a 2700mAh battery, 0.1C would be 0.1 times
2700mAh which equals 270mA.

Choosing the right charging & discharging rate
Charging at a rate below 0.33C and above 1.0C is not

Charging too slow may prevent the charger from terminating correctly.
Charging too fast may damage the battery.
Typically speaking, slower charging rate will yield better battery
performance but requires longer time. Faster charging rate may not
charge as fully and battery temperature can be higher.

Battery Matching

Powerex Mh C9000 Battery Charger

In most devices, usually two or more batteries are used together. When
batteries are used in a series, the performance is limited by the worst
one. In other words, one poorly performing battery can significantly
reduce the device runtime.
Battery matching refers to grouping batteries with similar “actual”
capacity. To perform this, use the Refresh & Analyze mode to determine
the battery capacity. Group batteries with capacity within about +/- 5% of
the rated capacity.

Battery “Forming”

New batteries and those stored for extended period become chemically
deactivated. Battery forming is a charge-discharge-charge cycle which
forces a full charge into the battery at a very slow rate. This process
activates the battery. In certain cases, it needs to be repeated two or
three times.
Battery forming can be performed using the Break-In mode.
