AER COMPACT MOBILE 2 - Battery Operation and Care

5.5 Battery operation and care
The battery in yourCompact Mobile 2 is a high-end
leakproof and maintenance-free lead-gel-battery.
It‘s high capacity will be available for a long time if
you follow some precautionary measures.
1. Charging
To charge the battery, plug your Compact Mobile 2
to the mains and switch it on. If you do not want to
use the amplier during the charging process, turn
gain- and master-control to minimum volume (as
far left as possible).
The charging of the batteries will be indicated by
the yellow charge-LED. The battery is fully charged
when the charge-LED is o. Charging time depends
on various factors and can vary according to the
battery’s charging state at the beginning of the
process.
A partly discharged battery will be charged
completely after a few hours whereas the charging
process of a completely discharged battery can last
more than 24 hours. The average charging-time of
a continually discharged battery will take about 8
to 14 hours. By constantly controlling the battery’s
voltage, the intelligent charge control electronics
prevents the battery from overcharge.
2. Operation
A completely charged battery allows 2 to 4 hours of
playing independent of mains supply, depending
on volume and dynamics. Low volume will enable
you to play up to 8 hours. The low-battery-LED
indicates that the battery is almost empty.
As soon as the minimal allowed battery voltage has
been reached, the charge control electronics will
automatically switch the Compact Mobile 2 o, in
order to avoid deep-discharge. After the amplier
has been switched o by the charge control elect-
ronics it can only be operated when connected to
the mains. A discharged battery should be charged
as soon as possible. Storage in discharged condition
may damage the battery.
3. Storage and self-discharge
If your Compact Mobile 2 is stored or not used over
a long period, the battery should be fully charged
in order to keep it‘s capacity. Being switched o for a
long time with discharged battery may damage the
battery irreparably by natural self-discharge. During
normal use, the charge control electronics can pro-
tect the battery from deep-discharge, but it cannot
prevent the electronical process of self-discharge in
the battery itself.
Always store your Compact Mobile 2 with charged
battery. A fully charged lead-gel-battery will still
be 60% charged after one year of storage whilst a
discharged battery might be damaged even after a
few weeks.
4. Temperature Dependency
Please note that the battery’s capacity (and thus
playing time) depends on the surrounding tempe-
rature. Playing outside in winter will reduce playing
time by 20 to 30% compared to playing in heated
rooms or outside in summer. This is a normal reac-
tion and not a sign of a defective battery.
5. Battery Life Expectancy
The producer of the batteries used in the AER Com-
pact Mobile 2 declares a life period of approximate-
ly 5 years at intended use.
6. Warranty
Batteries are items that wear out through the
ordinary course of use, thus they are excluded from
statuary two-year liability. If a defect has not been
caused by AER manufacture, warranty will expire
after 6 months.
7. Battery Exchange
The exchange of worn out batteries should be
carried out by a specialist or by AER Service as
both amplier and new battery could be severely
damaged through improper connecting or assem-
bly. Improper connection may cause explosion or
electric shock.
