What is the battery model for GAC Trumpchi GS4 key?
2 Answers
The battery model for GAC Trumpchi GS4 key is CR2025. CR2025 is a lithium manganese dioxide battery, named according to IEC standards. 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 used for square batteries; 20 indicates the battery diameter is 20mm; 25 indicates the battery height is 2.5mm. The nominal voltage is 3.0V, the endpoint voltage is 2.0V, and the rated capacity ranges from 140-170mAh. The shelf life of CR2025 is typically 5 years. If the manufacturer's production level is not high or quality control is poor, the lifespan can be significantly shortened. Domestic first-tier brand batteries can generally guarantee this lifespan. Under ideal usage conditions (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 involves the following three steps: Step 1: Remove the mechanical key. Press the lock button 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, while 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. Once opened, you will see the coin cell battery. Gently pry it out to remove the battery. Step 3: Replace the new battery. Install the new battery, then reattach the battery cover and mechanical key in order. The key battery replacement is now complete.
I've owned my Trumpchi GS4 for over three years and replaced the key fob battery twice, both times with CR2032 models which are readily available at supermarkets or online platforms like JD.com. When the battery was low last time, the remote control range noticeably shortened, so I simply used a coin to pry open the key casing and replaced the battery in under five minutes. However, be careful not to use excessive force to avoid damaging the internal chip, and ensure correct battery polarity alignment as improper installation may prevent operation. Battery lifespan typically lasts one to two years depending on usage frequency, with colder weather potentially increasing power consumption. It's advisable for owners to conduct regular checks to avoid lock/unlock failures at critical moments. As a side note, symptoms of a dead key fob battery extend beyond remote malfunction—it may also cause the start button to become unresponsive, making timely replacement crucial.
