4. Battery Discharge
4.1. 1.5V Constant Voltage Discharge
Jugee discharges energy at a 1.5V constant voltage while
the charge is released, creating a feeling as if the battery
is always feel “as fresh”.
4.2. Low Voltage Warning
Jugee battery will lower output voltage to 1.1V when its
internal energy is nearly depleted, as a signal in order to
avoid sudden power cut without warning.
⚫Special Notes
A. When used devices with battery gage, the
remaining charge indicator or bars would reduce
only at the point when the battery is in low energy
state.
B. With other types devices, low battery charge
condition can be observed from the reduced power
C. The amount of energy reaming at low charge state
varies by the different Jugee battery models. Please
see the datasheets attached to this manual.

11
4.3. Usable discharged energy
Jugee battery capacity rated in accordance with the “5-
hour discharge method”, a standard adopted in China
and internationally. Below is table of measured energy
using this method for different Jugee battery models:

2100mWh
⚫Special Notes:
To help consumers estimate battery capacity in
actual use, Jugee battery use mWh as the
metric of storage capacity. This is not to be
confused with the mAh metric used by some
other battery brands.

12
To understand the difference in meaning between mWh
and mAh, and how to use this to estimate usage
performance, please read Appendix 2 and 3.
4.4. Over-discharge Protection
Jugee battery employs over-discharge protection, which
automatically shuts off battery power output when
energy is depleted, hence avoiding potential damages to
battery. User is thus assured of normal use of the
battery till it is auto-shut.
⚫Notes:
After depletion shut-off, Jugee battery terminal voltage is
0V. This is a normal for battery in over-discharge
protection.
4.5. Timely Recharge After Depletion
The Jugee battery is exhausted or stored in a depleted
state. It is best to charge it within 10 days after the
battery is discharged. The maximum length is not
recommended for more than 30 days to avoid damage to
the battery and affect the use of the battery. This a critical
point about requiring user attention!
⚫Attention:

13
Should allowed recharge delay period has elapsed after
Jugee battery is depleted, over-discharge condition could
damage the battery, to degrees ranging from reduced
capacity, shortened cycle life, to malfunction of the
battery in the most server case. Slight damage to battery
is detected and automatically repaired by the built-in
electronics, but some irreversible degradation to the
battery is to be expected.
4.6. Over-Current Protection and Reverse Polarity By-Pass
Jugee battery has over-current protection, and a by-pass
function where a depleted cell in a series can allow
current continuation with reversed polarity, so the series
can continue to provide power. This feature makes it
easier to put batteries in series, as the user does need to
be concerned with state of charge or relative ages of cells
in a series.
⚫Attention:
A. Serial connection of cells of different state of
charge or relative age is limited to Jugee battery
models listed in this manual, namely EN5C3W0
and EN7C1W0. It is not permitted to mix Jugee
batteries with other makes of batteries, or

14
damage to Jugee batteries or the other cells can
be caused.
B. Jugee battery in depletion shut-off mode does not
have active over-current or over-temperature
protection. It is therefore necessary to limit working
current of series string to 1A.
4.7. Discharge overload or short-circuit protection:
Jugee battery has protection against discharge overload
or short-circuit, and limit discharge current to
approximately 2.5A, to protect external electric devices
from series damage when overloaded or short-circuited.
⚫Notes
A. Jugee battery is not harmed in over-load or short-
circuit protection mode, however, the battery may
become hot due to the rapid discharge current.
B. The over-load / short-circuit protection function of
Jugee battery is effective in protecting the external
device or the battery, but it limits current rating of
the battery, which may render the battery
incapable of power certain high-current
applications, such as camera external flash with
flyback boost or class-4 high power racing model car.

15
4.8. Discharge Temperature Protection
Jugee battery has discharge temperature protection,
which shuts down battery power output when battery
cell temperature is higher than 60℃ or lower than -30℃.
Battery discharge function automatically resumes once
the temperature is in the range of60℃ ~ - 30℃.
⚫Note:
Do not store or use Jugee battery in environment of
temperature higher than 60℃ (e.g. inside of a car on a
summer day) or lower than -30℃, to avoid damages to
the battery.
4.9. Discharging in Series
When multiple Jugee batteries are connected in series,
power output is not stopped when one of the batteries is
depleted and shut down. However, energy released or
discharging power of individual batteries in the series are
not necessary uniform, nor will the batteries in the series
all reach low-energy state, or enter into depletion shut-
down mode at the same time.
⚫Note:

16
A. When Jugee batteries are put into series
connection, the combined voltage and total
power will increase. Connection of more than 10
batteries together should only be performed by
electric power technical professionals.
B. A Jugee battery operating in revered polarity
current continuation mode will incur certain
voltage drop (typically 0.3-0.4V) cross its terminals.
When the battery is used in series: If any one of the
batteries is exhausted and the discharge is turned
off, the total series voltage is approximately equal
to the sum of the remaining battery voltage minus
the drop.
Take the 4-cell Jugee battery in series as an example.
After any one of the batteries is exhausted, the
output voltage of the series battery pack is: 1.5*4-
1.5-0.4=4.1V
C. Under depletion shutdown mode Jugee battery’s
discharge over-current or over-temperature
protection is unavailable. It is therefore necessary
to ensure that total discharge current of a series of
batteries, especially when one of the batteries in
the series is depleted, should be limited to 1A.

17
4.10. Discharging in parallel
When multiple Jugee batteries are connected in parallel,
current will never flow from batteries of higher remaining
charge to lower ones (even when batteries operate in
1.5V and 1.1V modes co-exist). However, energy released
or discharging power of individual batteries in the group
are not necessary uniform, nor will they all reach low-
energy state, or enter into depletion shut-down mode at
the same time
⚫Note:
When Jugee batteries are connected in parallel, the
voltage cross the group is equal to the highest among the
individual batteries in the group, and therefore the total
discharge energy and current will increase. Connection
of more than 10 batteries together should only be
performed by electric power technical professionals.

18
5. Charging the Battery
5.1. Compatible Chargers
Jugee batteries can only be charged with chargers
showing the label MILPEB mark. MILPEB chargers
contain charging regulator and protection circuits, and
ensure normal, rapid and safe charging operation for
Jugee batteries.
Charging Jugee batteries with non-MILPEB chargers can
significantly reduce charging speed, and cause no-charge,
incomplete charge or even damage to the batteries
and/or the chargers.
⚫Notes:
The Jugee battery of the model listed in this manual
can also be charged using MILBEP's old 4-cell
charger (CUM54). It should be noted that the
charging time of the old charger may be longer, and
may be accompanied by the phenomenon that the
battery LED indicator flickers at a low frequency.
5.2. Use with a USB 5V power source
To use 110/220/240V AC power, a 5V USB power adaptor
must be used. The following guidelines should be used
when selecting the USB 5V adaptor:

19
A. For 4-cell charger, adaptor current rating should be
no lower than 3.0A;
B. For 2-cell charger, adaptor current rating should be
no lower than 1.5A;
⚫Note:
If a USB 5V power adaptor used has a current rating lower
than the above requirements, Jugee battery may exhibit
under-power protection mode when charging. Under this
condition, not only will the charging time increase
significantly, the 5V USB power source will also be in full
load condition. This should be avoided in general, unless
for emergency short period of time.
5.3. Charging from a computer USB port
When charging from USB port with any Jugee charger,
use the following guideline to determine the number of
Jugee batteries that can be charged at the same time:
A. For USB port V1.0 or lower, 1 type AA batteries;
B. For USB port V2.0 or higher, 2 type AA batteries;
C. For USB port Type-C, 4 type AA batteries(You need
to bring your own Type-c to Type-c cable).
