The Autel X Star Premium battery is known for its reliable performance, but like all batteries, it can eventually lose its ability to hold a charge. This guide details how to potentially revive a dead Autel X Star Premium battery that hasn’t been used for an extended period. This process involves carefully disassembling the battery, applying a controlled voltage, and reassembling it. Disclaimer: This process is risky and should only be attempted by individuals with experience in electronics repair. Improper handling of lithium-polymer batteries can lead to fire or explosion.
Steps to Revive a Dead Autel X Star Premium Battery
Reviving a dead battery requires patience and precision. Here’s a step-by-step guide based on a successful attempt:
Disassembly and Preparation
-
Carefully open the battery casing: Refer to online resources like YouTube videos for detailed instructions on disassembling the Autel X Star Premium battery. Exercise extreme caution to avoid damaging the battery cells.
-
Detach Internal Components: Remove the charging connector and charge controller board from the battery casing while keeping them connected to the battery terminals. This allows access to the battery cells for direct charging.
Controlled Charging Process
-
Disconnect Charging Circuitry (Optional): While not strictly necessary, you can desolder the charging circuitry from the battery terminals. This isolates the battery cells for a more direct charging approach.
-
Apply Low Voltage: Using a variable power supply capable of delivering up to 30V and 3A, set the voltage to 12V and the current to the lowest possible setting without causing the voltage to drop.
-
Connect to Battery Terminals: Connect the positive and negative leads of the power supply to the corresponding terminals on the battery. Monitor the voltage closely. The initial voltage might drop but should gradually increase. Warning: Perform this step in a fire-safe area.
-
Monitor Voltage and Disconnect: Observe the voltage rise. Once it reaches around 8V, disconnect the power supply. Briefly connect the charging circuitry to assess the battery’s response. The battery indicator LEDs might faintly light up.
-
Repeat with Higher Voltage: Repeat step 4, but this time allow the voltage to reach 12V before disconnecting. Check the battery indicator LEDs again. They should show a more significant charge level.
Reassembly and Testing
-
Resolder Charging Circuitry: Carefully solder the charging circuitry back onto the battery terminals. Ensure solid connections to prevent issues during flight. Avoid short circuits and exercise extreme caution when working with the positive battery lead.
-
Reassemble the Battery: Put the battery components back into the casing, ensuring proper alignment and secure closure.
-
Charge with Autel Charger: Attempt to charge the reassembled battery using the official Autel charger. If the battery charges successfully, it has been revived. If not, the battery might be beyond repair and should be discarded safely.
Conclusion
While this method has proven successful in some cases, it’s not guaranteed to work for all dead Autel X Star Premium batteries. Always prioritize safety when working with lithium-polymer batteries. If you’re uncomfortable with any of the steps, consult a qualified technician. Remember, attempting this process is at your own risk.
