How many years does a 4008 car start-stop battery generally last?

[VonJocelyn]

The original car battery has a service life of 3 to 4 years, while ordinary car batteries last 2-3 years. Extended information on battery maintenance is as follows: The battery is most afraid of low temperatures. In low-temperature environments, the battery's capacity is much lower than at normal temperatures. Therefore, timely inspection and maintenance are essential. In daily life, pay attention to the following: 1. Avoid long-term parking: Avoid leaving the car parked in an open parking lot for extended periods. If long-term parking is necessary, remove the battery to prevent freezing damage. 2. Car engines are harder to start in winter: Each start attempt should not exceed 5 seconds, with intervals of at least 15 seconds between attempts. If the car doesn't start after multiple attempts, check other aspects like the circuit, ignition coil, or fuel system. Avoid continuous unsuccessful starts, as this can cause the battery to over-discharge and burn out. 3. Charge the car battery regularly: A battery left unused will gradually self-discharge and eventually become unusable. Therefore, start the car periodically to charge the battery. 4. Cleaning: Clean the battery terminals regularly and apply special grease to protect the wiring harness. Frequently check the battery's accessories and connecting wires. 5. Avoid using car electronics after the engine is off: Using the battery alone when the engine is not generating power can cause damage.

My 4008's start-stop battery has been running steadily for three and a half years now. These AGM batteries with start-stop function are actually more delicate than regular ones, and their lifespan largely depends on your driving habits. Like me, driving daily in city traffic with frequent start-stop system activations, mechanics say they typically don't last beyond four years. If you often drive on highways where the battery gets fully charged, it can last around five years. Last month, I had the battery capacity tested, and the mechanic said it's down to 60% and I should prepare to replace it. It's recommended to check the battery terminals for corrosion every six months and minimize using car electronics after turning off the engine. Recently, I noticed the start-stop isn't as responsive as before, which is a warning sign. It's best to have a new battery ready in advance.

Attention to all 4008 owners, the replacement cycle for start-stop batteries really can't be calculated like regular car batteries. My battery died at just 50,000 kilometers, and the 4S dealership said it was normal wear and tear. Their diagnostic tool showed that deep discharges exceeding 400 times are dangerous, especially when using air conditioning in summer traffic jams where frequent start-stop actions severely damage the battery. Now I maintain it quarterly with a charger and always turn off the AC and radio before shutting down the engine to extend its lifespan. The original battery costs over 2,000 RMB, while third-party brands around 1,000 RMB can also work. The key is to choose an EFB or AGM battery compatible with the start-stop system - installing the wrong type may burn out the control module.

As a long-time Peugeot owner, I'd like to remind everyone to monitor the health of your start-stop battery. My 4008's battery suddenly died after three years and two months of use, and seeing the 'STOP' warning on the dashboard was truly nerve-wracking. These batteries typically fail due to three main reasons: power leakage from long-term vehicle inactivity, insufficient charging from short-distance driving, and overload from aftermarket electrical modifications. It's best to conduct a test before each winter – be alert if the voltage drops below 12.4V. A mechanic taught me a trick: if your headlights noticeably dim when starting the engine, or if the start-stop function stops working, these are the battery's final warnings. I now always keep a portable jump starter handy to avoid getting stranded on the road.
