The charger display will indicate ‘DONE’ when all the batteries connected to
that channel have received as much charge as they can safely accept:
PL16 Display
PL16+ Display
3.10
As Li-Ion batteries near the end of charge, the charge current is reduced.
This is perfectly normal for the ‘constant voltage’ phase of the charge cycle.
3.11
Batteries may be removed, and others connected at any time, without affecting
the operation of the charger.
3.12
The charger will continue to monitor the status of all charging channels.
It will not attempt to charge batteries which the charger indicates are ‘DONE’
or faulty (indicated as ‘FAIL’). When there are no batteries connected the
charger display will indicate ‘ABST’:
PL16 Display
PL16+ Display
If a new battery is connected to the free channel, the charging sequence will
be initiated automatically. The order in which batteries are connected is
therefore immaterial; the charger will ensure that all batteries are charged in
as short a time as possible.
3.13
If the charger detects a faulty battery while the charging program is running,
the display will show ‘FAIL’. This could be caused by one of several conditions,
such as a very old or damaged battery, a short circuit battery, or an excessively
high or low voltage battery.
3.14
The charger will not recognise the connection of a battery which has a
voltage substantially outside of its range or one of unsuitable chemistry type.
3.15
If the internal protection circuit of a PAG or Sony Li-Ion battery should turn-
off, for any reason, the battery display will not operate, and there will be no
voltage at the battery terminals. The PL16 incorporates a Recovery Charge
program which will automatically turn the protection circuit back on again.
3.16
If the charger should detect a fault during operation, it will shut down to
a safe condition. See Section 5.4 ‘Servicing and Repairs’.
