What to Do When the Car Shows a Battery Symbol?
2 Answers
When the car shows a battery symbol, it indicates low battery voltage. Charging at 1500 rpm for 20 minutes can eliminate the warning. Here is some information about automotive batteries: 1. The battery is an essential part of a car and can be divided into traditional lead-acid batteries and maintenance-free batteries. 2. Maintenance-free batteries use lead-calcium alloy grids, which produce less water decomposition and evaporation during charging. Additionally, due to their sealed structure, they release minimal sulfuric acid gas. Compared to lead-acid batteries, they offer advantages such as no need to add any liquid and longer charge retention.
I've been driving for nearly twenty years, and the battery light on the dashboard is a common sight—usually indicating the alternator isn't charging the battery properly. When this happens, don’t push your luck by driving far; find a safe spot to pull over and turn off the engine. First, check if the battery terminals are loose or corroded. If you see greenish powder, clean it off with baking soda solution and tighten them. Then, start the engine and measure the battery voltage—it should normally read between 13.5 to 14.5 volts. If it’s lower, it might be an alternator or belt issue. Last month, my battery light came on, and after checking, I found the alternator’s output was weak. I rushed to the repair shop for a replacement, saving my long-distance trip. Make it a habit to inspect the belt and battery health every six months—it saves hassle, money, and keeps you safe.
