19.1- Battery & Charger
UF 801-P/PB has an internal NiMH battery pack. This pack includes some
protection against short circuits, an over charging or over temperature.
This battery is permanently supervised by a dedicated component & circuitry that
looks for all input/output currents. This component, after self calibration (see
below) will show its
autonomy time as a % of the full capacity
at a dedicated
line in measurement menu. It also drives the fast/slow charging sequence.
To prevent damage due to a too low battery voltage, these supervising circuits
have an automatic power-off, if this voltage becomes lower than an internally set
threshold.
User battery life:
Completely charged new batteries should offer a continuous
use of 12~14 hours. It is possible to increase this service time by using the ON /
OFF sequencer (See §16).
Charger use / Charging time:
Connect the charger at Mains 100 to 240 V AC
50/60 Hz (Green LED must be lighted) and plug-in the output to UF 801-P
dedicated connector. The typical charging time is 2.5 hours.
When battery is charged, the charge supervisor switches from high to low current,
to maintain the charge but also to supply an UF 801-P that is kept ON.
In that case, the charger can be considered as an external supply. No problem to
use this supply module during a long period, but monitor the unit periodically.
Attention! If you detect a too high temperature at UF 810-P/PB back or
any abnormal situation, please unplug the charger supply and advise
Ultraflux after sales service.
How to re-initialize the battery supervisor?
To have a correct display of the
battery level, it is necessary to calibrate this range in relation with the actual
battery condition. To do this, do a complete cycle after the UF 801-P has been
automatically powered off by low battery voltage detection (that set the zero %)
up to the maximum charge (that sets the 100%).
We recommend doing this every two months.
19.2 Battery pack whole life
(exchange: see 20.4)
Any battery pack has a limited life depending on the complete number of
charge/discharge cycles, and also the care you have had for their use.
NiMH technology offers typically 500 complete cycles following IEC standard.
So, during your UF 801-P life, it will be normal to exchange the battery pack.
