Take out the tail end of the key, push the marked switch upward, and the hidden mechanical key will pop out slightly, allowing you to remove the mechanical key. Use the extracted mechanical key to press against the marked position, and with a gentle force, the key casing can be opened. After removing the key casing, you will find the battery positioned deep inside. Gently pry from the gaps on both sides with a tool to remove the old battery. After replacing with a new battery, reassemble by following the installation steps in reverse order.

What does a horizontally opposed engine mean?

A horizontally opposed engine refers to an engine where the pistons are evenly distributed on both sides of the crankshaft, moving left and right in a horizontal direction. This design reduces the overall height and length of the engine, lowers the vehicle's center of gravity, and enhances driving stability. The horizontally opposed engine is mounted along the vehicle's central axis, with the torque generated by the pistons on both sides canceling each other out, reducing vibrations during driving, allowing for higher engine speeds and reduced noise. The characteristics of a horizontally opposed engine include: 1. The lateral vibrations it produces are easily absorbed by the mounts, achieving overall balance; 2. The piston movement is well-balanced, ensuring smooth engine operation.
