How does temperature affect voltage?

The temperature rises, the voltage drops; the temperature drops, the voltage rises.

Can the battery be used up before charging it?

Hurry up and power it is recommended to charge the battery when the battery power is lower than 80% of the rated power storage capacity.

How does temperature affect the specific gravity of the electrolyte?

The temperature rises, the electrolyte volume expands; the temperature decreases, the electrolyte volume shrinks. Therefore, the temperature reading must be corrected when measuring the specific gravity.

What is the maximum temperature limit for charging?

Lead-acid battery charging temperature cannot exceed 120 degrees Fahrenheit (48.9 degrees Celsius). When the temperature reaches this degree, the battery should be cooled to continue charging.

Will the battery be discharged when not in use?

All batteries, regardless of their chemical characteristics, will have self-discharge. The self-discharge rate depends on the battery type and the temperature of the battery storage location. TROJAN batteries have a weekly self-discharge rate of about 4% at 80 degrees Fahrenheit.

Will the battery freeze?

The battery is in a partially discharged state, and the electrolyte will freeze. The battery will freeze when the self-discharge is above 40% and the temperature is lower than 6 degrees Fahrenheit; the freezing temperature of a fully charged battery is -92 degrees Fahrenheit.

How does temperature affect the performance of the battery?

Higher temperature (above 77 degrees Fahrenheit, or 25 degrees Celsius), the battery's storage capacity increases, but it will shorten the battery life. Higher temperature will also increase self-discharge at the same time, lower battery temperature (below 25 degrees Celsius) will reduce the battery's storage capacity but at the same time extend the battery life. Lower temperature will also reduce self-discharge. Therefore, use the battery at about 25 degrees Celsius to obtain the best battery performance and life.

What are the most common mistakes made by battery users?

Lead-acid battery is undercharged: usually after using the battery, the battery cannot be fully charged. Continued under-charging or not storing the battery fully charged can cause sulfates to accumulate on the plates-usually called salinization. This will reduce the performance of the battery and cause permanent damage to the battery, as well as the "stratification" phenomenon.

Overcharge: Continuous charging will accelerate the corrosion of the positive plate and the consumption of water.

Insufficient moisture: In long-term use, the moisture in the battery will be lost during the charging process. If the electrolyte level is lower than the top of the electrode plate, irreparable damage will occur. The liquid level should be checked frequently.

Too much water: Adding too much water will cause electrolyte overflow and affect battery performance. At the same time, adding water before charging will also cause electrolyte overflow
