The colloidal battery is a new generation of valve-controlled battery, which is already sealed at the factory, it is not easy to add electrolyte! If it is added, it will not form a colloid so that the electrolyte will leak in use! Battery repair instrument should repair it. The battery repair instrument should be a problem that the battery capacity caused by an negative electrode irreversible sulfate caused by overcharge or overlapping during use. When fixing, the electrolyte concentration is lowered, and the smaller current charge and discharge is used.

. . After repeating several times, then re-adjust the concentration and height of the electrolyte.

The colloidal battery electrolyte is in colloid, it is not easy to lower its concentration. I can't fix it! Personally I suggest you see that the battery is not within the warranty, you can find the battery and ask if you can change! There are two measurement indicators of the battery life, one is the period of floating life, that is, in the standard temperature and continuous floating state, the maximum capacity of the battery can be released when the maximum capacity used is not less than 80% of the rated capacity; the second is the depth of the depth The number of cycles, that is, the full capacity of German sunlights removes 80% of the rated capacity, and then filled with electricity, so that the number of times that is recycled. Typically, engineers and technicians pay only attention to the former, and the latter is ignored.

The 80% depth cycle charged charge represents the number of times the battery can actually use, in the case of frequent power failure or high quality, when the actual number of times the battery has exceeded the number of cyclic charges, although the actual use time is still Did not reach the calibrated floating life, but the battery is actually invalid. If it is not possible to find a big accident hidden danger. Therefore, when choosing the battery, we should pay attention to the two life indicators.

Under the conditions of the main interruption of the mains, the latter is especially important. When choosing the UPS supporting German sunlight, we should consider enough floating life margins. According to experience, the actual service life of the battery is often only 50% to 80% of the calibration of the floating life.

This is because the actual floating life of the battery is related to many factors such as defining standard temperatures, actual ambient temperatures, battery charging voltages, and maintenance. When the actual ambient temperature is 10 ° C per liter than the defined standard ambient temperature, the battery will be shortened by half the internal chemical reaction rate, so the UPS battery computer room should be equipped with air conditioning equipment. In terms of defining temperature values, the European standard is 20 ° C, China, Japan, USA and other standards are 25 ° C.

20 ° C 10 years of battery life-free battery is converted to 25 ° C standard, only the life of 7 ~ 8 years. The nominal floating life of the supporting battery should be the value obtained by using the actual service life of the battery we want. This life factor is usually determined by empirical, and the battery reliability is 5.

8, and the reliability is low. How to repair the colloidal battery is a new generation of valve controlled battery, which is already sealed at the factory, it is not easy to add electrolyte! If it is added, it will not form a colloid so that the electrolyte will leak in use! Battery repair instrument should repair it. The battery repair instrument should be a problem that the battery capacity caused by an negative electrode irreversible sulfate caused by overcharge or overlapping during use.

When fixing, the electrolyte concentration is lowered, and the smaller current charge and discharge is used. After repeating several times, then re-adjust the concentration and height of the electrolyte. The colloidal battery electrolyte is in colloid, it is not easy to lower its concentration.

Can the colloidal battery repair _ Colloidal battery How to repair _ colloidal battery repair method as follows 1, charging method: Generally, a lighter battery, can recover normal charging. Generally, the larger the discharge current, the shorter the battery life; the deeper the discharge depth, the shorter the life of the battery. From theoretical battery, try to avoid deep discharge, you should be shallow.

2, hydrotherapy: a "water therapy" charge and discharge. (1) 0.5 ml of the 500 ml of drip bottle capacity with the hospital with a 0.

5 ml of 0.5 ml of the pure concentrated sulfate, which is a dilute sulfate electrolyte having a density of approximately 1.050 as hydrating.

(2) Open the battery on the cover (must be careful to avoid damage), rotate the single-handed control valve (or pick the rubber cover), add 5 ml of the electricity of 1.050 of 1.050 -15 ml, injecting the electrolyte It is preferred to put the battery for more than 10 hours, so that the replenishing liquid is soaked into the separator to just see the flow electrolyte appear (more clearly, more clearly by flashlight) or the battery is flip 90 degrees, so that the small hole As side, excess electrolyte overflow, then fell back).

(3) Connect the battery and tester, press the Tester "Battery Repair" function button to repair. The tester automatically enters three six-hour debris repair, automatically transfer to the working mode "3" after three hours, heat-charged - charging, charging current is 3A, the discharge current is 5A, the tester automatically display discharge Capacity and time, very intuitive. Each record, repeated three, four times until the capacity is no longer rising.

3. Battery parallelism: If the battery temperature rise is rapid during repair, the charging current should be reduced. At this time, the two batteries can be connected in parallel, and the charge and discharge of electric current is original 1/2.

1/2 (Ignore the internal resistance difference), the effect is also very good. 4. Battery series repair method: This method is used when the single battery nominal voltage is below 12V.

For example, on the market, charging emergency lights often use 6V4AH, as well as 6V7AH battery, and the tester single output is 12V. 5. Output joint charge increase method: If the battery capacity is repaired, if some cars are 100AH ​​batteries, sometimes it is necessary to increase the charging current, at which time the two or more outputs of the tester can be repaired in parallel.

Battery to enhance charging current. .
