CONGA 990 EXCELLENCE Robot Vacuum- Checking the condition of the battery

What you need

  1. CONGA 990 EXCELLENCE Robot Vacuum- Checking the condition of the battery, CONGA 990 EXCELLENCE Robot Vacuum- Checking the condition of the battery: step 1, image 1 of 2 CONGA 990 EXCELLENCE Robot Vacuum- Checking the condition of the battery, CONGA 990 EXCELLENCE Robot Vacuum- Checking the condition of the battery: step 1, image 2 of 2
    • Checking the battery voltage and verifying that the voltage from the recharge cradle reaches the battery.

    • Necessary tools:

    • Phillips "star" screwdriver, medium size.

    • Digital multimeter with DC Volts, VDC measurement

    • Optional: 2 office clips and insulating tape or heat shrink tubing to wrap around them.

  2. CONGA 990 EXCELLENCE Robot Vacuum- Checking the condition of the battery: step 2, image 1 of 2 CONGA 990 EXCELLENCE Robot Vacuum- Checking the condition of the battery: step 2, image 2 of 2
    • With a medium sized Phillips screwdriver, unscrew the 2 screws of the battery cover.

    • We will check in the data sheet what is the voltage of the same. In this case it is 14.4 V. To disconnect or to replace the battery we have next to this the white connector, we press the tab, and stretching we release the battery.

    • The hole for inserting the multimeter test leads is quite narrow, so we can use office paper clips if the test leads do not fit.

    • Multimeter scale to be used, V DC scale higher than 15 V. In this multimeter the closest upper scale is the 20 V scale.

    • With the side ON/OFF switch open = OFF, we measure the battery.

    • Measured between 14.4 and 14.5V

    • Activating the side power button ON/OFF, we proceed to measure the battery again. In this case, since the robot is running and there's battery consumption, the voltage drops slightly. For example, it measures 14.18 V.

    • We place the charging base on the 2 charging terminals of the robot. (I put the battery on top to ensure good contact between the terminals). We will verify that the voltage should increase, going from 14.5 V to a charging voltage of 14.72 V or slightly higher.

    • By activating and deactivating the side ON/OFF button, we will observe how the voltage varies between the battery voltage and the charging voltage.

    • In this case, both the battery and the charging base have correct voltages.

    • This check is performed to rule out a common battery problem in this type of cleaning robot. Once the battery issue is ruled out for this specific robot, the fault is localised to one of the wheels/motors.

Conclusion

To reassemble your device, follow these instructions in reverse order.

Mi conga da 4 pitidos cuando está acabando la carga de la batería y según parece es porque hay que cambiarla, sin embargo cuando lo pongo en marcha está funcionando como hora y media por lo que parece que la batería aún está en buen uso ¿Que puede ocurrir? Gracias.

Inicialmente la bateria podria estar ok si dices que dura tanto, pero habria que medirla con voltimetro, aplicando una carga para ver el voltaje real de la misma que puede estar ligeramente bajo.

No creo que sea una averia yo apostaria por un cambio de bateria, y limpieza de todas las partes moviles de las ruedas y cepillos.

Hola. Micoga 990 está sin estrenar. La pongo a cargar y da tres veces 4 pitidos con la luz roja fija. Que puede ser. Gracias

Hola mi conga 990 se pone en marcha y a los dos minutos se para y ya le he cambiado la bateria

Hola Ana, puede ser eque falle el cargador y no este recargando la bateria, lo primero seria medir el voltaje de salida del cargador, 2º medir el voltaje que tiene la bateria cuando falla para ver si es bajo, si el problema es el cargador, si lo demontas te podria indicar alguna cosa, como cual seria el condensador que posiblemente esta fallando.
