What kind of maintenance method does the battery in winter?

Battery maintenance method: After more than 2 years of battery, the battery is used, the capacity and discharge capacity will drop. General car battery life will not exceed 4 years. Of course, maintaining a good battery life will be longer.

Let's learn the maintenance method of water-based lead-acid batteries and maintenance-free lead-acid storage. Water-type lead-acid battery: pay attention to battery liquid level and battery fluid density. The battery fluid of the lead-acid battery is formed by mixing sulfuric acid and distilled water.

When the battery is discharged, the water varies more and the sulfuric acid will increase, which results in a decrease in the density of the battery liquid; when charging, the water will become less, and the sulfuric acid will change. The concentration of the battery reflects the ratio of water and sulfuric acid in the battery fluid. Normal electrolytic solution density is 1.

28 (summer) / 1.29-1.30 (winter) (unit of gram per cubic centimeter).

As the owner, we should check the battery liquid level regularly. When the battery fluid is insufficient, distilled water should be added to the appropriate level. After adding distilled water to the battery, we should check the battery-liquid density, always keep the battery fluid density within a reasonable range.

Maintenance-free lead-acid battery: regularly check the magic eye and keep your power sufficient. Due to the maintenance-free battery, there is no water hole and the battery fluid level scale. We need to judge the state of the battery through the magic eye on the battery.

The magic eye is green to indicate that the battery is normal, charging the foot; the magic eye is black, indicating charging; the eye is white to replace the battery. Dispelling capacity to detect a dedicated battery detector. We generally use a voltmeter to check the battery voltage, although it can detect the voltage value of the battery but cannot check the battery load capacity.

In order to check the actual situation of the battery, we should use a dedicated battery detector to check the battery's discharge capability and the capacity of load.
