Steps to replace the battery of a dash cam: 1. Unscrew and open the back cover; 2. Pry open the control panel connected to the buttons; 3. Remove the screws on the circuit board, cut the old battery from the wires, and replace it with a new one to complete the process. A dash cam is an instrument that records images, sounds, and related information during vehicle travel, consisting of a main unit, speed sensor, and data analysis software. Functions of a dash cam: 1. Protect the legal rights of drivers; 2. Playback recorded footage to assist traffic police in handling accidents; 3. Record scenic views during road trips.
I'm the kind of person who enjoys DIY projects, and replacing a dash cam battery is actually quite simple. First, you need to confirm the device model because battery locations and sizes vary by brand. Look up tutorials or video guides online and prepare a small screwdriver and tweezers. The crucial step is to power off the device to avoid short circuits—unplug the dash cam's power cable. Carefully remove the casing without forcing it to prevent damaging components. Take out the old battery, note the polarity clearly, and ensure the new battery matches the voltage when purchasing—common options include 3.7V 18650 lithium batteries. When installing the new battery, make sure the connection is secure and test that the device powers on and records properly. After installation, seal it tightly to prevent dust from entering, which can affect lifespan. Battery aging is often caused by high temperatures; parking in the shade during summer can extend its life by several years. Take your time during disassembly to avoid costly damage.
As a car owner, I believe safety is more important than anything else. Before replacing the battery, park the car and turn off the engine, then wear rubber gloves for protection. When removing the dash cam, handle it gently and avoid poking the interior with metal tools. Check if the wiring connections are loose. Old batteries may leak, so make sure to wrap and recycle them properly instead of discarding them carelessly. Common mistakes include purchasing the wrong battery specifications or reversing the polarity, which can lead to device burnout and wasted money. I recommend consulting the manufacturer's manual or seeking help from online communities first. After replacement, test the functions to ensure everything works properly and avoid power failure on the road. Additionally, regularly cleaning the lens and checking battery health can prevent issues and extend the dash cam's lifespan. Opting for durable battery brands is more reliable and reduces replacement frequency.
