7. Battery recharge
During normal functioning, the presence of a valid external source of power supply (with a socket
as symbol) or low battery condition (with the symbol of a battery) is shown in the display to the
right of the first line. From the moment the symbol appears, about 90 minutes of autonomy remain.
Recharging of REI2’s internal batteries is managed entirely by the microprocessor. In this way it
has been possible to implement a recharge control which guarantees maximum efficiency of the
batteries at all times, at the same time prolonging their operational life.
When you enter this function, the current state of power supply is shown on the sixth line of the
display as follows:
•
‘Battery use …’
the internal batteries are being used
•
‘Maintenance’
the stopwatch is supplied by the external power source and at the same time the
efficiency of the batteries is maintained by a trickle charge but they are NOT recharged
•
‘Discharge…’
the internal batteries are completely discharged before being subsequently
recharged
•
‘Recharge’
recharge in progress; on the right, the time remaining before the end of recharge is
shown
•
‘Recharge blocked’
recharge has been temporarily interrupted because of insufficient voltage.
It will resume automatically as soon as a voltage level is restored.
To recharge the batteries, connect the plug for recharging to any continuous current supply between
11 and 24 volts. In the REI2 package a special adaptor is provided for mains power supply (220V).
To recharge the batteries or completely discharge them, REI2 must remain switched
on. During recharge it is possible to carry out every kind of timing. The important
thing is not to switch it off.
After a reset the battery gauge cannot calculate the battery status correctly ( ). It
will therefore be necessary to carry out a Charge/Recharge cycle to have accurate
knowledge of battery status.
7.1. Discharge/recharge
When this function is selected, the internal batteries are first completely discharged and then
recharged. This is the most correct procedure for keeping the internal batteries at maximum
efficiency.
The duration of the discharge phase depends on how fully the batteries are charged and can last up
to about 3 hours.
The duration of the subsequent recharge phase is 7 hours for the old type of battery (in version
1.07.9.0), while for the new type (in version 1.07.9.1) it is about 9 hours 15 minutes. At the end of
recharge the message
‘RECHARGE OK!’
appears.
7.2. Immediate recharge
If it is not possible to charge or recharge in the correct way because of lack of time or for any other
reason, it is possible just to recharge. In this way recharge time is reduced but this procedure is not
recommended as it reduces the efficiency of the batteries.
