OPERATING THIS PRODUCT INCORRECTLY CAN
CAUSE DAMAGE TO THE BATTERIES.
READ MANUAL COMPLETELY BEFORE USE.
GENERAL PRECAUTIONS
•Do not charge battery cells other than NiMH or NiCD. Please check with the battery manufacturer to ensure it can accept the programmed charging and discharging rates. Do not expose the unit to rain or moisture due to the risk of fire.
•Do not operate the charger if it appears damaged in any way.
•Always place the battery cells with positive tip facing the top. Incorrect polarity may cause fire or explosion. Observe polarity diagrams located on the charger.
•Do not allow the unit to be exposed to direct sunlight. Operate in
•Do not allow the battery terminals to become shorted.
•To reduce the risk of damage to the power cord, always pull by connector rather than the cord.
•Use only the supplied adapter or optional regional and car adapter offered by Maha Energy. Using third party accessories voids the product warranty.

GENERAL BATTERY EDUCATION
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 recommended.
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
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
