The capacity of a battery is a matter of great concern to users. Can businesses determine the reliability of a battery’s capacity? Today, experts from Zhengzhou Lixun Electronics will analyze the testing methods for battery capacity. We can test the battery capacity ourselves:
The self discharge of batteries and gradual sulfurization of plates are inevitable “gradual failures” of lead-acid batteries, but with increasingly strict requirements for product materials and processes, such as changing lead antimony alloy to lead calcium alloy, it gradually becomes “maintenance free throughout the process”. Some people are accustomed to using only the voltage range of a voltmeter or multimeter without adding a load to check if the battery is fully charged, which is very unreliable. Because even for a battery that has been started and discharged, once the discharge is stopped, the open circuit voltage electromotive force between the positive and negative plates of the battery and the electrolyte can be reached immediately, and the potential difference between them can be restored. Each cell is about 2.1V, and the entire battery is about 12.6V or more. When measuring voltage alone, the current consumption is extremely low, so there will be no large voltage drop inside the battery, so the displayed voltage is not low. However, if a considerable load is added, such as headlights (10~15A) and speakers (6~12A), the battery will dim the lights and make the speakers hoarse, indicating insufficient battery storage.
When the electrolyte level is too low, both small balls will fall to the limit position. At this time, the observation hole will show “outer red and inner colorless” (with a colorless transparent circle in the center and a red ring around it), indicating insufficient electrolyte and that the battery cannot continue to be used and must be replaced. If this type of detection plug is installed on a dry charged battery, it means that distilled water must be added. The English description is marked as “Adddistilledwater”
Batteries are large components that are prone to wear and tear, with a lifespan of up to 3-4 years and 1-2 years. Moreover, the more frequently a car is driven (especially for long-distance use), the longer the lifespan of the battery; The more frequently a car or bus is parked, the shorter its battery life is due to frequent discharge but insufficient charging.
