Why Can’t My Smart Lithium Battery Be Activated Or Turned Off?

Unfortunately, when your Smart lithium battery can not be activated or turned off, there could be a variety of reasons behind the problem. The issues might stem from a damaged communication port or external factors unrelated to the lithium battery itself. It may require some trial and error as well as battery troubleshooting to uncover the underlying cause.

What Are The Factors That Affect The Activation Or Deactivation Of A Smart Lithium Battery?

1. The battery is currently in the process of charging or discharging, preventing it from being switched to sleep mode.

2. The battery has been over-discharged, triggering BMS protection and preventing the battery from being activated.

3. The activation switch is damaged.

4. The communication port is damaged.

Troubleshooting Steps:

1. Exclude the impact of charging and discharging processes. During charging or discharging, the activation switch may not work. Please disconnect all connections from the battery and then attempt to switch the battery status using the activation switch. (Some loads with internal capacitors may briefly charge the battery with a very small current.)

------Possible Results------

Positive: Able to switch. This function is normal.

Negative: Unable to switch. Please try other steps.

2. Exclude the possibility of BMS undervoltage protection. Measure the open-circuit voltage of the battery to check if it is below 10V.

------Possible Results------

Positive: Voc < 10V. The battery is in BMS undervoltage protection, and the status cannot be switched. It is necessary to charge the battery using a device with lithium battery activation function.

Negative: Voc > 10V. The battery is not in BMS undervoltage protection. Please try other steps.

3. Exclude the possibility of a damaged activation switch. Try cross-validation by replacing the activation switch or using a different battery.

------Possible Results------

Positive: Activation switch is faulty. Follow the after-sales process.

Negative: Activation switch is normal. Please try other steps.

4. Exclude the possibility of damaged communication port. Please check the battery's communication port to see if there is any corrosion or damage.

------Possible Results------

Positive: Communication port is corroded or damaged. Unable to communicate. This will be determined as a misuse causing the communication to fail.

Negative: Communication port is undamaged. Please try other steps.

If all the influencing factors mentioned in steps 1, 2, 3, 4 are ruled out, it can be determined that the product itself is faulty.
