What is the lifespan of the Boyue key battery?
3 Answers
The lifespan of the Boyue key battery is 2 to 3 years. The functions of the battery are: 1. Provide strong current to the starter when starting the engine; 2. Assist the generator in supplying power to electrical equipment when the generator is overloaded; 3. Supply power to electrical equipment when the engine is idling; 4. Protect automotive electrical appliances. Taking the 2020 Boyue as an example, it belongs to a compact SUV with body dimensions of: length 4519mm, width 1831mm, height 1694mm, wheelbase 2670mm, fuel tank capacity 58L, and curb weight 1575kg. The 2020 Boyue is equipped with a 1.8T turbocharged engine, with a maximum horsepower of 163PS, maximum power of 120kW, maximum torque of 250Nm, and is paired with a 6-speed manual transmission.
I've been using the key fob for my Boyue for about two and a half years now, and I find the battery quite durable. It really depends on how you use it. I don't press the buttons frequently, so I haven't had to replace the battery yet. However, a friend of mine who often uses the trunk and lock buttons had to replace his in less than two years. Remote key fob batteries are usually those small coin-type ones, like CR2032, and their performance can degrade over time, especially in cold winters or hot weather. It's a good idea to regularly check if the key's indicator light flashes slower or if the unlocking distance shortens—these are signs that it's time to replace the battery. Don't wait until it's completely dead and you can't lock the door, causing unnecessary trouble. Replacing it yourself is simple: just pry open the back cover, pop in a new battery, and you're done—no need to spend extra money at a repair shop. In short, paying attention to your usage habits can help extend the battery's lifespan, making it more cost-effective.
As a Boyue owner, I've observed that the key battery typically lasts around two years, but the specifics heavily depend on individual usage. For instance, my car key is mainly used for unlocking doors and starting the engine, with minimal button presses, so the battery lasts longer. However, some owners have added remote control features, and frequent usage drains the battery faster. The battery type is CR2032 lithium, and its aging rate is significantly affected by environmental conditions—exposure to summer heat or humid weather accelerates degradation. I recommend purchasing a small tool to check the voltage; if you're inexperienced, refer to the user manual for replacement steps. Actually, replacing it early is low-cost, just a few dollars each time, avoiding the embarrassment of being stranded in a parking lot at night. Also, avoid leaving the key in a hot car during daily storage, which can extend its life by a few months.
