COMMONLY USED TERMS
41 42
We guarantee this product to be free of manufacturing and assembly defects for a period of one year
from the time of purchase. The warranty only applies to material or operational defects, which are
present at t he time of purchase. During that period, we will repair or replace free of service charge for
products deemed defective due to those causes.
You will be required to produce proof of purchase (invoice or receipt). This warranty is not valid for
any damage or subsequent damage arising as a result of misuse, modification or as a result of failure
to observe the procedures outlined in this manual.

WARRANTY AND SERVICE
Commonly used terms
Final charge voltage: the voltage at which the battery's charge limit (capacity limit) is reached. The
charge process switches from a high current to a low maintenance rate (trickle charge) at this
point. From this point on further high current charging would cause overheating and eventual
terminal damage to the pack.
Final discharge voltage: the voltage at which the battery's discharge limit is reached. The
chemical composition of the batteries determines the level of this voltage. Below this voltage the
battery enters the deep discharge zone. Individual cells within the pack may become reverse
polarised in this condition, and this can cause permanent damage.
A, mA: unit of measurement relating to charge or dis-charge current. 1000 mA = 1 A (A=Ampere,
mA=Milliampere)
Ah, mAh: unit of measurement for the capacity of a battery (Amperes x time unit; h = hour). If a
pack is charged for one hour at a current of 2 A, it has been fed 2 Ah of energy. It receives the
same quantity of charge (2 Ah) if it is charged for 4 hours at 0.5 A, or 15 minutes (=1/4 h) at 8 A.
'C'-rating: Capacity is also referred to as the 'C' rating. Some battery suppliers recommend charge
and discharge currents based on the battery 'C' rating. A battery's '1C' current is the same number
as the battery's rated capacity number, but noted in mA or amps. A 600mAh battery has a 1C
current value of 600mA, and a 3C current value of (3 x 600mA) 1800mA or 1.8A. The 1C current
value for a 3200mAh battery would be 3200mA (3.2A).
Nominal voltage(V): The nominal voltage of the battery pack can be determined as follows;
-.NiCd or NiMH: multiply the total number of cells in the pack by 1.2. A 8-cell pack will have a
nominal voltage of 9.6 volts (8x1.2).
-.LiPo: multiply the total number of cells in the pack by 3.7. A 3-cell LiPo wired in series will have a
nominal voltage of 11.1 volts (3x3.7).
-.LiIo: multiply the total number of cells in the pack by 3.6. A 2-cell LiIo wired in series will have a
nominal voltage of 7.2 volts (2x3.6).
-.LiFe: multiply the total number of cells in the pack by 3.3. A 4-cell LiIo wired in series will have a
nominal voltage of 13.2 volts (4x3.3).
If the nominal voltage of the battery is not printed on the battery's label, consult your battery
manufacturer or supplier. Do not guess the rated voltage of battery.
