What is the battery model for the GAC GS4 key?

[VanMichael]

The battery model for the GAC GS4 key is CR2025. CR2032 is a lithium manganese dioxide battery, named according to the IEC standard. Among them: C- indicates a chemical battery system with lithium metal as the negative electrode and manganese dioxide as the positive electrode; R- indicates that the battery is cylindrical in shape, with F replacing it if it is square; 20 indicates that the battery diameter is 20mm; 25 represents the battery height of 2.5mm. The nominal voltage is 3.0V, the endpoint voltage is 2.0V, and the rated capacity ranges from 140-170mAh. CR2025 typically has a lifespan of 5 years. If the manufacturer's production level is not high or quality control is poor, its lifespan will be significantly shortened. Domestic first-tier brand batteries can generally guarantee this lifespan. If the usage environment is ideal (sealed, room temperature, free from moisture, etc.), the lifespan can be further extended to 8 years or even 10 years. Generally, replacing a car key battery only requires the following three steps: Step 1: Remove the mechanical key. Press the buckle on the side of the smart key to remove the mechanical key. Step 2: Open the battery cover. After removing the mechanical key, you can see a deep groove and a shallow groove at the top of the smart key. The deep groove is the keyhole, and the shallow groove is used to open the battery cover. Insert the mechanical key into the shallow groove and pry it outward to open the battery cover. After opening, you can see the coin cell battery. Gently pry it, and the battery will come out. Step 3: Replace the new battery. Install the new battery, then reattach the battery cover and mechanical key in order, and the key battery replacement is complete.

The remote key battery model for the GAC GS4 is typically CR2032, a common button cell battery. I remember last year when my key suddenly stopped working and the indicator light was dim, I checked the manual and realized the battery was dead. I replaced it myself: gently pry open the key casing, locate the battery compartment, and the old battery was a CR2032. The new battery costs just a few bucks and can be bought at supermarkets or hardware stores—just make sure not to get a CR2025 or CR1632 by mistake, as their size and voltage differ, which could cause the key to malfunction. The key battery usually lasts one to two years. Try to avoid exposing the key to high temperatures, like leaving it in a sun-exposed car, as this shortens its lifespan. If the remote frequently fails, check for oxidation or loose contacts on the battery terminals to catch issues early and avoid awkward situations. Regular maintenance saves a lot of hassle, especially in winter when battery performance drops faster.

The GAC GS4 car key uses a CR2032 battery, which is a 3-volt lithium coin cell with a diameter of 20mm. I've replaced it several times because the key's range decreases with prolonged use, and when the buttons stop responding, it's time for a replacement. CR2032 batteries are quite common—not just for car keys but also for watches or small appliances—so buying them at an electronics market offers good value. The tools needed for replacement are simple: use a small screwdriver or a card to pry open the key's back cover, being careful not to force it and damage the casing. The battery compartment has polarity markings; avoid installing it backward. After inserting the new battery, test the remote's responsiveness. If the battery drains frequently, it might indicate an internal circuit issue, but 90% of the time, it's just battery aging. I recommend choosing reputable brands like Panasonic or Sony for stable quality and to avoid leakage from off-brand batteries. For daily storage, keep the key away from phones or strong magnetic fields to extend its lifespan, saving money and ensuring safety.

The battery for the Trumpchi GS4 key is CR2032. From a practical perspective, here's my advice: When the key becomes unresponsive, first try pressing the unlock button near the car window. If it works, it confirms the battery is low. Replacing the battery yourself is simple: Prepare a new CR2032 battery, pry open the key casing (usually at the middle seam), remove the old battery, insert the new one with the positive (+) side facing up, then close the case and test it. The whole process takes less than five minutes, saving you unnecessary costs at the dealership. Make sure not to confuse the battery model—CR2025 is thinner and may cause poor contact if used. You can find these batteries at supermarkets for just a couple of yuan; brands like Double Deer or GP are recommended. The key typically requires maintenance every 1-2 years. Avoid dropping or exposing it to water to protect the circuitry. This battery model is also compatible with other Trumpchi models, making it a universal solution.
