The method to check car battery power is: observe and check through the battery indicator eye. The main function of the battery indicator eye is to allow the user of the battery to visually see the battery's power storage status. The battery power storage status is mainly divided into three states: green or blue indicates good condition; black or red indicates the need for charging; white indicates the battery needs replacement. A car battery, also known as a storage battery, is a type of battery that works by converting chemical energy into electrical energy. Car batteries are divided into conventional batteries, dry-charged batteries, and maintenance-free batteries. Usually, when people refer to a battery, they mean a lead-acid battery.

Are Speed Cameras Active in Highway Construction Zones?

According to regulations, temporary speed limits due to construction are considered special circumstances where speed cameras are not activated. For example, if the normal speed limit is 100 km/h but reduced to 60 km/h due to construction, you won't receive a traffic violation as long as you don't exceed 100 km/h. Regarding visibility and distance requirements during adverse weather conditions like rain, fog, sandstorms, or hail: 1. When visibility is less than 200 meters: Turn on fog lights, low beams, position lights, and front/rear position lamps; maintain speed below 60 km/h and keep a distance of over 100 meters from other vehicles. 2. When visibility is less than 100 meters: Activate fog lights, low beams, position lights, front/rear position lamps, and hazard warning flashers; speed must not exceed 40 km/h with a minimum 50-meter distance from preceding vehicles in the same lane. 3. When visibility drops below 50 meters: Use all aforementioned lights plus hazard flashers; speed must stay under 20 km/h, and exit the highway at the nearest available ramp as soon as possible.

Why is a new battery still not fully charged after 13 hours?

New battery not being fully charged after 13 hours is due to a blown battery fuse or poor contact between the fuse tube and fuse socket. Below are specific details about charging a new battery: 1. Master the charging time: The first charge of a new battery affects its lifespan and charge capacity. Insufficient charging will result in lower charge capacity and reduced lifespan; while overcharging may improve electrical performance but also shortens the battery's lifespan. Therefore, it's crucial to properly time the first charge for a new battery. 2. Charging method: First, use the initial current (one-tenth of the battery's capacity) until the electrolyte bubbles and the single-cell voltage rises to 2.3-2.4V. Then, continue charging with half of the initial current until the electrolyte bubbles vigorously, and the voltage remains stable for 3 hours. Generally, after the charger indicator light turns off, continue charging for 1-2 hours. The total charging time should be about 8-10 hours. Avoid overcharging as it can negatively impact the battery's lifespan.
