individual cell resistance without external resistance meter.

Capacity Limit

Charging capacity will increase as the charging goes on. If the charging
capacity exceeds the limit, the charging process will be terminated
automatically when it reaches the limit you set.

Temperature Threshold

Battery internal chemical reaction will cause the battery temperature to
rise. When the temperature limit is reached, the process will be
terminated.

This function is available by connecting optional temperature probe, which
is not included yet.

Warning and Safety Notes Warning and Safety Notes

Have you selected the appropriate program for the battery type you are
charging?

Have you set up adequate current for charging or discharging?

Have you checked the battery voltage? Please note that Lithium battery
packs can be wired in parallel or in series, i.e. a 2 cell pack can be 3.7V
(in parallel) or 7.4V (in series)

Have you checked that all connections are firm and secure?

Make sure there are no intermittent contacts at any point in the circuit.

Charging

During charge process, a specific quantity of electrical energy will be fed
into the battery, which is calculated by multiplying charge current. The
maximum permissible charge current differs on different types of battery
and its performance, which can also be found in the information by the
battery manufacturer. Only batteries to be capable of quick-charge are
allowed to be charged at higher rates than the standard charge current.

Connect the battery to the charger terminal, red is positive while black is
negative. Due to the different resistance between cable and connector,
the charger can not detect the battery pack's resistance. To work
properly for a charger, it's essential for its charge lead to be of adequate
conductor cross-section, and high quality gold-plated connectors must
be fitted to both ends.

Please always refer to the manual by battery manufacturer about
recommended ways of charging, charging current and time, especially
for a Lithium battery, which must be charged according to the instruction
strictly.

Special attention must be paid to the Lithium battery connection.

Never attempt to disassemble the battery pack arbitrarily.

Always remember: Lithium battery can be wired in parallel or in series.
In parallel connection, the battery capacity is calculated by multiplying
each individual battery cell capacity with total voltage staying the same.
Voltage imbalance may cause fire or explosion. Lithium battery is highly
recommended to charge in series.

Discharging

The main purpose of discharging is to clean residual battery capacity, or
to discharge the battery to a defined level of voltage. Final discharge
voltage must be set correctly to avoid over-discharging. Lithium battery
can not be discharged to be lower than its required minimum voltage, or
it will cause a rapid loss of capacity or a total failure. Please pay
attention to the minimum voltage of Lithium battery to protect it.

Some rechargeable batteries have memory effect. If they are partly used
and recharged before whole charging is accomplished, they will
remember this and only use that part of capacity next time. Above is
called memory effect. It is said that both NiMH and NiCd batteries suffer
from memory effect, NiCd, however, suffers more.

“DCHG>CHG” or “CHG>DCHG“. The “DCHG>CHG”
option will first discharge the battery and then
recharge the battery.

The “CHG>DCHG” option will first charge the
battery and then discharge the battery. If this
screen does not show your desired cycling
option, press the START button once and this
setting will begin flashing. Use the INC or DEC
button to change this setting.

Pressing the START button again will cause the
cycle count to begin flashing. Use the INC or
DEC button to change this to the number of
cycles you want the e660 to run. The e660 can
cycle the battery a maximum of 5 times
consecutively.

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 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): 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).

-.LiHV: multiply the total number of cells in the pack by 3.7V. A 4-cell LiHV
wired in series will have a nominal voltage of 14.8 volts (4x3.7).
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.
