Transmitter Battery: Inspection
WARNING: This page is about a different car, the 2007 Toyota Land Cruiser. However, it is still accessible from the selected car via links, so may be relevant.
- INSPECT BATTERY CAPACITY
HINT:
- The capacity of the battery can be determined only when the battery is installed in the transmitter. For a lithium battery used in the transmitter, a voltage of more than 2.5 V is shown on the tester until the energy is completely consumed without the battery installed in the transmitter. Therefore, it is necessary to measure the voltage with the battery installed in the transmitter (a resistance of 1.2 kΩ is applied to the battery) to check the amount of energy left in the battery.
- If the transmitter is faulty, the amount of energy left in the battery may not be measured correctly.
- Connect the lead to the negative (-) terminal of the transmitter and install the battery.
- Connect the positive (+) tester probe to the positive (+) side of the battery (lithium battery) and the negative (-) tester probe to the lead.
- Press one of the transmission switches on the transmitter for approximately 1 second.
- Press the same or another transmission switch again and check the voltage.
Standard voltage: 2.2 V or higher
NOTE:- If the temperature of the battery is low, the inspection cannot be done correctly. If the outcome of the test is less than 2.2 V, conduct the test again after leaving the battery in a place with a temperature of 18°C (64°F) for more than 30 minutes.
- The automatic power-off function causes the battery voltage to be 2.5 V or more (with no resistance applied to the battery) when 20 seconds have passed after the switch is pressed. Therefore, make sure to read the voltage immediately after the switch is pressed.
- Disconnect the lead.
