INFORMATION ABOUT THE FUNCTIONING AND THE MAINTENANCE OF
THE BATTERIES
Ni-MH batteries, used in the Tapping Machine, can work for some years, but just if used
correctly.
Their life is longer if they are used regularly and in the correct way, instead if they are
used a few times the life of the batteries will be shorter.
The main cause of the damage is due to the spontaneous self-discharge. When the batteries
are new it is up to 1% each day, but if used incorrectly the spontaneous self-discharge
could reach the 5% a-day ( 20 days are sufficient to discharge completely the battery
risking to damage it permanently).
Not all the elements of the Battery Pack get old at the same time and in the same way.
Because of this, after some time( especially if the battery is not used a lot), some elements
that are part of the battery pack could be “ slightly damaged”, modifying their ability of
supplying electrical current and the work potential difference.
In this case, the total potential difference of the Battery Pack (composed of n.21 cells in
series “21x 1.2 v=25.2V” assumed value )will not be as it was in origin, it will be as lower
as many elements are damaged, and the electrical current will certainly be lower than the
minimum one necessary for the correct functioning of the Tapping Machine.
If this is the situation, you can try to reactivate the Battery Pack making some
charge/discharge cycles proceeding in this way.
1) Charge the Battery Pack until full charge (Green led on).
2)Wait for at least 30 minutes to let the battery cool itself.
3)Repeat the sequence of charge, turning the Switch Off and then On (Switch 2)( leveling
of the electrical current of the cells) and wait until the charge is completed( Green led on).
4)Wait until the battery is cold. Turn the Switch n.2 Off and On again.
5)Push the internal button “CONDITIONING”(n.6). The orange led (n.7) will turn On and
it will start the procedure of battery discharge.
It could take 10/15 hours to complete the discharge.
When the battery is completely empty, the orange led (n.7) will turn Off and the procedure
of recharge will immediately start( yellow led On n.8). At the end of the charge the green
led(n.9) will turn on.
6)Wait for at least 30 minutes to let the battery cool itself, turn Off and then On the Switch
n.2 (second leveling of the electrical current of the cells) and let the battery charge again.
End of the process of Battery Pack Conditioning(recond)
Now use the Battery Pack and verify its functioning.
Pay attention: When the battery is new, the Tapping Machine can work ceaselessly for
40/50 minutes ( push the START side of the switch n.3).In St-By mode the Battery Pack
will be able to work for about 50 hours.
MAINTENANCE OF THE EFFICIENCY OF THE BATTERY PACK
To extend the life of the Ni-MH batteries it is important to keep them charged and, in case
of irregular or missed usage, repeat the charge cycle each 1-2 month(s).
The batteries will work better if the Battery Pack is charged the day before the use of the
Machine( if the B.P. is old, repeat the charge cycle twice before using it to “ level the
charge of the cells”).
The potential difference values can be read on the Voltmeter placed on the rear panel.
