BATTERY CHECKING AND REPLACEMENT
Internal Battery
The rechargeable battery in TestBook will not
normally need to be serviced. It allows a technician
to disconnect TestBook from one vehicle and
reconnect it to another without the loss of data.
When TestBook draws power from an energy source
other than the internal battery, the yellow indicator
light is on.
However, if the battery life drops below five minutes,
it is possible to extend it. This is described later in
this section.
Battery Operation
TestBook’s internal nicad battery is designed to
power TestBook only when moving it between a
power point and a vehicle. It will normally provide
fifteen minutes of power when fully charged. For
power within the vehicle, use the Road Test Power
Supply provided. Never attempt a road test using
only TestBook’s internal battery.
BATTERY RESTORATION PROCEDURE
(TESTBOOK 2)
Perform this procedure at the end of the working
day. It should take less than fifteen minutes. If it
takes longer, the battery didn’t need restoration.
1. Leave TestBook "ON" at the Welcome screen.
2. Without turning TestBook off, unplug the
external power supply.
3. Wait for the internal battery to discharge
completely.
4. Plug TestBook back into an external power
supply.
5. Leave TestBook plugged in overnight. The
TestBook itself does not need to be left
switched ON.
6. The battery should last longer the following
day. If the battery life is still less than five
minutes, please telephone the Helpdesk for a
replacement TestBook.
NOTE: TestBook must be plugged into
either a power point or a Road Test Power
Supply in order for it to be switched ON.
TestBook, by design, will not turn ON from
internal battery power.
The nicad battery recharges whenever TestBook is
plugged into an external power supply. Return the
unit to the external power supply as soon as
possible after a road test so that it can begin
recharging for the next road test.
The time needed to re-charge a fully drained battery
varies with ambient temperature:-
Two to three hours if temperature is less than 30°
Centigrade/Celsius.
Overnight if warmer than 30° Centigrade/Celsius.
The battery despatched in new TestBook units is
uncharged. They must to be fully charged before
they will provide power. This simply means leaving
them in TestBook overnight while it is plugged into
an external power supply. TestBook does not need
to be turned ON during recharging.
After a while, it may be noticed that TestBook’s
battery does not last as long as when it was new. To
extend the charge life of the battery the following
steps should be carried out.
