What is the battery model for the Trumpchi GS4 key?
2 Answers
The battery model for the Trumpchi GS4 key is CR2025. CR2025 is a lithium manganese dioxide battery, named according to the IEC standard. The breakdown is as follows: C - Indicates a chemical battery system with lithium metal as the negative electrode and manganese dioxide as the positive electrode. R - Indicates the battery shape is cylindrical; if it were square, it would be denoted by F. 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. CR2025 typically has a lifespan of 5 years. However, if the manufacturer's production standards are low or quality control is poor, the lifespan may be significantly shortened. Batteries from top domestic brands can generally guarantee this lifespan. Under ideal conditions (sealed, room temperature, no moisture, etc.), the lifespan can be extended further, up to 8 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 will see a deep slot and a shallow slot at the top of the smart key. The deep slot is the keyhole, while the shallow slot is used to open the battery cover. Insert the mechanical key into the shallow slot and pry it outward to open the battery cover. Once opened, you will see the button cell battery. Gently push 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 sequence. The key battery replacement is now complete.
I've got plenty of experience changing the key battery for Trumpchi GS4. Last month, my old GS4 key suddenly stopped working and couldn't unlock the car doors, which had me hopping mad. Turned out the CR2032 coin battery was dead. Just buy a new one at the store for a few bucks. The replacement is simple: use a small screwdriver to pry open the key slot, remove the old battery, insert the new one with the positive side facing up, and snap it back together. These batteries typically last over a year, though cold weather drains them faster. I recommend keeping a spare battery in your car to avoid embarrassing situations like mine. Also, if the key's been used for long, the contacts might get dirty - a quick wipe helps. Changing the battery yourself saves a trip to the mechanic.
