Methods for judging distance using car rearview mirrors: 1. When the rear vehicle is in the safe zone and positioned at the center of the rearview mirror, it indicates a distance of 15 to 20 meters from the rear vehicle, allowing normal turning operations; 2. If the rear vehicle occupies half of the rearview mirror area with only half of its body visible, this means the distance is very close, and you should maintain your current lane; 3. If the rear vehicle occupies one-third of the side mirror area with the entire car visible, the distance is about 15 meters, making turning operations possible; 4. If the rear vehicle's grille is completely obscured, the distance is 3 meters, which is a safe following distance at low speeds.

What is a Maintenance Battery?

Maintenance batteries are refurbished batteries by manufacturers. Here are the specific details: Nature: Maintenance batteries refer to recycled, repaired, and reused batteries (lower grade), commonly known as refurbished batteries. Warranty: The warranty for maintenance batteries typically ranges from 12 to 15 months. If the battery develops quality issues, the manufacturer will replace it with another set of maintenance batteries. Quality: The quality of maintenance batteries is inferior to that of regular batteries because maintenance batteries are essentially batteries that have been repaired after a second-stage failure. The lead content inside is not purified again, which naturally affects the battery's performance.
