2.8 Lithium-ion baery
NOTE
Please make sure to follow the following instrucons for using lithium-ion
baeries!
a) Only charge the batteries in suitable chargers
if the battery is not used in a suitable
charger, it may be permanently damaged
.
b)
If the battery is not used for a longer period of time, it must not remain on the
charger or on the tool.
If a work break of more than 3 hours is expected, the battery
must be removed from the tool. Otherwise, the battery may be permanently damaged.
c)
The lithium-ion battery should not remain on the charger for longer than 36 hours
for safety reasons. Remove the battery from the charger immediately after the
charging process is completed.
d)
An empty battery should not be in contact with the tool or a charger that is
disconnected from the mains
for a longer period of time. In both cases, currents
can flow that
deep discharge the battery and can permanently damage it.
- 12 -
e)
Recharge the lithium-ion batteries immediately and
never store them when empty.
If the battery is stored while disconnected from the tool
and the charger, it will
maintain a constant capacity over a long period of time. (Loss approx. 5 % per year)
f)
Do not subject the lithium-ion battery to high temperatures (+ 50°C) or direct
sunlight. If the battery gets warmer than 50°C during operation (charging or
discharging), it must be removed from the charger or tool immediately.
g)
Keep the unused battery away from paper clips, coins, keys, nails,
screws or other
small metal objects which might bridge the contacts. Do not open the battery and do
not short-circuit it.
A short-circuit between the battery contacts can lead to burns, fire
or explosions.
h)
Under extreme use or temperature conditions, batteries can leak.
Avoid contact
with the skin or eyes if the battery leaks.
The battery fluid is acidic and can cause
chemical burns on tissue.
If the fluid comes into contact with skin, immediately wash it
with soap and water and then
rinse it with lemon juice or vinegar. If the fluid gets into
the eyes,
flush with water for at least 10 minutes and immediately go to the doctor.
i)
Make sure that the Li-Ion battery does not fall down or is subject to vibrations and
impacts.
j)
Clean the contacts on the batteries and charging station regularly with a cloth
soaked in high-percentage alcohol
or alternatively with a cotton swab.
NOTE
Lithium-ion baeries have nearly no self-discharge and do not have a memory
eect. If properly used, they will reliably supply your tool with power for
several years (approx. 800 - 1,200 charge cycles).
In general the following applies:
Avoid deep discharging or overcharging the lithium-ion baery under any
circumstances. It will be permanently damaged from this.

WARNING
The matching battery adapter and the correct software and firmware must
be mounted/installed to charge the batteries.
3.2 Addional informaon
If the operation voltage is connected and the charging station is switched on, a self test
will automatically start.
After switching on the charger, all of the LEDs will light up and then a signal will sound.
When all of the LEDs go off, the charging station is ready to use. Now batteries can be
inserted for charging.
NOTE
HS-Technik oers updates for the charging staon for download in the course
of further development. The operator is obligated to keep the charging staon
rmware up-to-date. HS-Technik does not assume any liability for defecve
baeries if the charging staon is not operated with up-to-date rmware.
- 17 -
WARNING
Make sure the polarity +/- is correct.
When replacing batteries, make sure the new battery is not inserted until the LEDs have
gone out (red or green).
If a battery is replaced very quickly, the electronics may retain the status of the previous
battery pack.
3.2.1 Charging process
Via an initialization routine, the voltage, temperature, short circuits and reverse polarity
of the inserted battery are checked.
Prior to starting the charging process, the temperature contacts (NTC contact, etc.) are
checked. If the temperature contacts are OK, the battery will be charged.
If the battery is too hot, it can stay in the charging station, and when it has cooled down,
it will automatically start the charging again.
If the red LED lights up, the charging process will start using the special HST frequency
modulation impulse process® and charge the battery based on how depleted the battery is.
During the charging process, the voltage and temperature of the cells and the remaining
charging time are continuously monitored.
Taking all of the parameters into account, the charging current and remaining charging
time varies on a case-by-case basis. The installed fans switch on automatically, as needed
during each charging process.
Every charging process can be recorded on an optional memory chip for subsequent
evaluation.

3.2.3 Sleep funcon
The sleep function defines the time after which the charging station or the boards
switches to sleep mode when it is not charging batteries. The time can be set freely up to
18:12:15 hours via the software. The charging station can be woken up from sleep mode
by pressing the wake-up button on the front or by putting on a battery.
Each board goes into sleep mode seperately after the set time if it is not in use. If the last
board goes in sleep mode the power supply will shut off.
NOTE
Prior to use, always check that the mounted baery adapter is compable
with the baery you wish to charge.
3.3 Safety funcons and special features
The battery is charged using the HST frequency modulation impulse charging process®
until a charging parameter is reached, then the charger switches to charge retention
mode.
A microprocessor monitors and controls every charging box and only supplies the battery
with as much energy as it can effectively absorb (dialog between the battery and charging
station).
This results in low heat development and faster and better storage of the capacity. This
special charging technology ensures the charging process is always extremely gentle on the
battery and guarantees a very long service life of the battery. Furthermore, this dynamic
charging technology automatically regenerates older batteries (that were charged with
other chargers) with reduced capacity, so these batteries can continue to be used.
No "memory effect" for Ni-Cd and Ni-MH batteries, due to the special charging technology,
the residual energy in the cells is shifted which prevents accumulation or crystallization
of the electrolytes. Every time the battery is charged, the cells are reformatted and the
electromechanical balance is rearranged. Thus, the voltage curve when discharging is
significantly higher than with other comparable charging processes. (More energy in the
form of joules can be discharged).
- 20 -
Higher capacity at lower currents.
The charging boxes are completely short-circuit-proof and protected against reverse
polarity so the batteries will not be destroyed. If the polarity is reversed or there is a
short-circuit, the charging box is disconnected from the power supply and a signal will
sound, accompanied by a red blinking LED.
(The highest level of safety is thus ensured.)
The fans are controlled based on need and cool the batteries quickly, even under extreme
stress.
Absolute protection against overloading via voltage monitoring and voltage gradient
evaluation a well as Delta U, charging time limitation and dynamic temperature evaluation.
Automatic dynamic evaluation of the temperature contacts depending on the adapter
type.
NOTE
Only for Ni-Cd and Ni-MH baeries.
3.4 Soware
• Special HST frequency modulaon impulse charging process® (absolutely no memory
eect due to variable frequency-modulated impulse charging current with a high am-
plitude)
• Self diagnosc (test of the internal power circuit)
• Polarity reversal protecon (power is disconnected from the charging box, accompa-
nied by a signal and a red blinking LED, disconnect charging box - baery)
• Special charge mode for Ni-Cd baeries (for deep discharging or dormant baeries)
• No voltage change required (baery voltage is detected automacally)
• Charging at baery temperatures exceeding 40° C (by generang gradients using dyna-
mic temperature evaluaon)
• Automac evaluaon of the temperature contacts (with NTC contact, a dynamic tempe-
rature evaluaon is performed, this depends on the baery adapter.)
