A comprehensive introduction to car battery knowledge, how to maintain the battery

The storage battery provides electrical energy for the start of the car and the electronic equipment in the car, and it is an essential part of the car. However, most car owners don't pay much attention to car batteries. Therefore, some problems caused by batteries are common, so we pay some attention to it. As for car batteries, let me introduce some knowledge about car batteries below.

A comprehensive introduction to car battery knowledge-types

Car batteries are divided into wet-charged batteries, dry-charged batteries, low-maintenance batteries and maintenance-free batteries. The product label of car battery is generally similar to "6-QAW-54a", Q stands for car battery, 6 stands for battery with 6 cells, A and W stand for battery type, A stands for dry-charged storage battery, and W stands for maintenance-free storage battery. If it is not marked, it means an ordinary battery, 54 means the rated capacity of the battery is 54Ah, and a means a first-generation improvement of the original product (b is a second-generation). Most of the cars nowadays use maintenance-free batteries, which is relatively easy, but the price is relatively high.

A comprehensive introduction to car battery knowledge-structure

The structure of a car battery mainly consists of positive and negative plates, separators, electrolyte, tank shells, connecting bars and pole piles. Most of the early batteries were ordinary lead-acid batteries, which required regular addition of electrolyte, that is, distilled water. Nowadays, most batteries use lead-calcium alloy as the grid, which produces less water decomposition during charging and low water evaporation. Coupled with the sealed structure of the outer shell, the release of sulfuric acid gas is also very small. Compared with traditional batteries, It has the advantages of no need to add liquid, strong resistance to overcharge, large starting current, and long power storage time.

A comprehensive introduction to car battery knowledge-maintenance

How to maintain the battery is a critical issue, and the daily maintenance of car batteries is very important. The first is the first charge of the battery, which has a great impact on the service life and charge capacity of the battery. If the charge is insufficient, the battery's charge capacity is not high, which will reduce the service life; but if the battery is overcharged, although the electrical performance of the battery is good, it will also shorten its service life. Therefore, the new battery must master the time of the first charge.

Furthermore, after the car is parked, try to minimize high-power electronic equipment while driving to avoid excessive battery power consumption. If the car is parked for a long time, it is recommended to unplug the negative battery of the battery to avoid power loss. It is recommended to start the car at least once a week to make the battery recharge by itself when the car is idling. Finally, you should often scrub the battery to clean the surface dust, oil and white acid powder, so as to extend the service life of the battery.
