BATTERY INSPECTION AND CHARGING
(TT-R125E/TT-R125LWE)
TIP
Since MF batteries are sealed, it is not possible
to check the charge state of the battery by
measuring the specific gravity of the electrolyte.
Therefore, the charge of the battery has to be
checked by measuring the voltage at the battery
terminals.
1. Remove:
• Battery cover
2. Disconnect:
• Battery leads
(from the battery terminals)
NOTICE
First, disconnect the negative battery lead 1,
and then the positive battery lead 2.
3. Remove:
• Battery
4. Measure:
• Battery charge
Measurement steps:
• Connect a pocket tester 1 to the battery
terminals.
Tester positive probe →
Tester negative probe →
TIP
• The charge state of an MF battery can be
checked by measuring its open-circuit
voltage (i.e., the voltage when the positive
terminal is disconnected).
• No charging is necessary when the open-
circuit voltage equals or exceeds 12.8 V.
