Remove the rear screws and open it slowly. This is the flat cable connecting the panel control buttons. Gently pry it open. After removing the screws on the circuit board, you can gradually see the battery. Then, disconnect its wiring. Compare the old and new battery compartments—as long as the voltage is the same, install it. Use a ruler to measure the length, width, and height before purchasing one. Prepare a soldering iron, using only the soldering iron and a small screwdriver as tools. A small piece of double-sided tape, with the key soldered onto it. It’s still in the original place, and the circuit board is being reassembled. It can be used after installation. Thus, the issue of replacing the dash cam battery is resolved.

When replacing the dash cam battery, I need to follow the steps carefully to ensure it's done correctly. First, prepare tools such as a small screwdriver, anti-static gloves, and a new battery. Most dash cams use 3.7V lithium-ion batteries, so make sure the size matches the original model—these can be purchased online or at auto parts stores. Before starting, turn off the dash cam's power and unplug all cables to avoid short-circuit risks. Next, locate the fixing screw holes, unscrew the casing with the screwdriver, and be careful not to damage internal wiring. The old battery is usually secured with adhesive tape—remove it gently and note the positive and negative terminal positions (reversing them can damage the device). After installing the new battery, test the power-on and charging functions to ensure they work properly. Regularly watch for signs of battery degradation, such as shorter recording times, and replace it early to prevent unexpected failures. The whole process takes about 10–15 minutes, and using a multimeter to check voltage is recommended for extra safety. If unsure about the battery type, refer to the manual or consult a professional installer.

I've personally experienced this. Once my dash cam kept running out of power and failed to record crucial footage, so I decided to try fixing it myself. I bought a new battery for just 30 yuan and looked up video tutorials online. First, I located the screws on the back of the device, opened it up, and saw the old battery attached with double-sided tape, which I gently peeled off. When installing the new battery, I made sure not to reverse the polarity, otherwise it wouldn't start. After one attempt, it successfully recorded a full journey. Since then, I've made it a habit to check the battery condition every six months. Replacing the battery yourself saves money and effort, but remember to disconnect the power first to avoid electric shock or damaging the device. If you encounter difficult-to-remove screws or lack the right tools, asking a friend for help or sending it for repair is also an option. Battery durability affects driving safety, so taking early action is a good idea.

Safety first! Replacing the battery may seem simple, but it carries hidden risks. Always ensure the vehicle is turned off and the power is disconnected, otherwise a short circuit could cause a fire or damage the device. Wear gloves before handling to avoid static electricity damaging the circuit board. Choosing the correct battery type is crucial, as incorrect voltage or size can lead to overheating or even explosion. It is recommended to back up video data beforehand to prevent accidental loss. When removing the casing, handle gently and avoid forcing it, as plastic parts can easily break. If the device is under warranty, opening it yourself may void the warranty, so consider professional service. Keep the environment dry and ventilated throughout the process, and keep children away. After completion, test the device by repeatedly starting it to confirm normal operation. Prevention is key—regular maintenance extends the lifespan of the dash cam.
