Precautions for using lead-acid batteries in winter

　　Author ：Iflowpower – Portable Power Station Supplier

With the winter battery capacity, with the winter, the temperature decreases, you will find that your equipment is very good, but even mistakenly think is the battery is broken. In fact: the optimum use temperature of the lead-acid battery is 25-30 ¡ã C, which has a new increase of the temperature, decreases with temperature reduction. At 27 ¡ã C or lower, the temperature is reduced by 11 ¡ã C, and the capacity drops by 10%.

Here temperature refers to the problem of electrolyte, not ambient temperature. Capacity drop solution 1. The internal battery is chemically reacted, the lower the temperature, the lower the reactive material activity inside the battery, and the capacity of the battery is also reduced.

In order to ensure the temperature of the electrolyte in the battery, put your device battery in a high temperature environment, and take certain warmth measures to the battery if necessary. 2. Electrolytic solution in the battery will completely freeze the extreme low temperature, the lower the specific gravity of the electrolyte, the lower the solidification point, and the capacity is small.

Therefore, please ensure that the battery acid density is normal, check and maintain in time. Standard density: 1.275 ~ 1.

285 specific gravity (25C). 3. Battery With the discharge, the internal electrolyte will transform water, and the electrolyte solidification point is lowered after depth discharge.

Once the frozen, it will be extremely difficult. Therefore, after the winter battery is discharged, please make time to charge! The initial capacity of the new battery in winter is lower than the rated capacity, the actual initial capacity is about 70% of the rated capacity, so the battery is to slowly reach the maximum performance or peak capacity after 50-100 cycles. This phenomenon is more obvious in winter because of the low temperature performance.

When you encounter a new battery, please don't worry if you have a significant lower capacity than the rated capacity, you will not be worried about a period of time. Battery Maintenance Connection Battery Tuning Columns If the gasket is used, make sure the battery wire is in contact with the lead surface of the terminal, and the gasket is placed on top of the wire joint, daily maintenance, please pay attention to safety. Please pay attention: Please wear rubber gloves when connecting, use rubber wrenches, recommended torque value 11 ~ 14.

7N.m battery maintenance, water 1. rich liquid / wet battery to increase water regularly.

The frequency of the water depends on the frequency and operating temperature of the user. Long-term lack of water, the polar is damaged, the electrolyte liquid is clearly visible 2. Please check the battery every 2 weeks to determine the battery's water supply frequency.

Typically, the longer the battery is used, the more frequent adding water frequency. Exhaust well 3. Please charge the battery before adding water.

4. If the plate is extremely bare, please add only the water that is just overwhelming, and then charging the battery. 5.

After charging, continue the following water step: a. Open the flip-type venting cap, check the height of the electrolyte liquid; please pay attention to: Then there is no need to add water; c. If the electrolyte liquid level has not been missed, add distilled water or deionized water, please add water to the exhaust water below 3 mm below the standard battery.

Battery maintenance and maintenance correct charging is a prerequisite for maximizing battery performance. Insufficient charging or excess charging may shorten battery life. a.

Please select the correct charging curve according to the battery model; b. You must check if the battery fluid is sufficient before charging, the battery should be charged after each use; c. Do not add liquid when charging D.

When charging, the electrolyte The temperature should be less than 50C. Long-term over-discharge and insufficient charging battery damage severe winter battery use you ask me to answer 01, after the equipment is high, after a period of time, it will show the power, stop for a period of time and restore power, what is the reason? A: This phenomenon is normal, does not affect battery life. The power displayed on the dial is the real-time voltage for detecting the battery.

Long-term continuous working battery voltage drop is normal, especially in winter, when the battery voltage falls faster when the equipment is operated, the display is faster, and the power generation is timely alarm, which is conducive to battery protection, this is also Set the original intention of low voltage alarm. 02. When the DT battery is used, is the burning pile head is more common? A: Burning pile head is able to prevent it, it is in the usual push, it is recommended that the customer will check whether the screws on the connecting site on the pile should be loose every week.

Do not use water To flush the battery's connection, use soda water to wipe the battery and don't let soda enter the battery inside. Cleaning the joint, prevent adverse effects on battery performance. 03, how to extend the battery life? A: Can not over-discharge and overcharge, the discharge depth cannot be less than 30%, so as not to cause excessive discharge, use it once to charge once, please test the electrolyte level, level Timely supplementation, add water to the precipitation plate, can not add sulfuric acid and electrolyte, can only add tea distillate and deionized water.

04, in what circumstances will the battery turn over? A: First, during use, exceeding the requirements for maximum discharge, continue to discharge. Second, after the battery is complete, no charging is placed in time. Third, the battery has been added, the placement time is longer, no supplement charge in time, will cause over-discharge due to its self-discharge.

05. What is the temperature range of the battery of the battery? A: The battery can be used in the 5C to 35C section to achieve the best performance. 06, add water is charged before charging or charging? A: Add water after chargin.
