COMMONLY USED TERMS
FINAL CHARGE VOLTAGE:
is reached. From this point on, further high current charging would cause overheating and
eventual terminal damage to the pack.
FINAL DISCHARGE VOLTAGE:
reached. The chemical composition of the battery determines the level of this voltage. Below
this voltage the battery enters the deep discharge zone. Individual cells within the pack may
become reverse polarized in this condition, and this can cause permanent damage.
A, MA:
unit of measurement relating to charge or discharge 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):
- NiCD or NiMH: Multiply the total number of cells in the pack by 1.2. A 8-cell pack wired in
series 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).
- LiION: Multiply the total number of cells in the pack by 3.6. A 2-cell LiION 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 LiFe 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 the battery.
