Switzerland leadline battery performance features:

 

 

 

Safety and sealing: the unique production process and special structure design are adopted to ensure the safety and sealing of the battery.

 

 

 

< maintenance free: the unique gas recombination system can regenerate the generated gas into water, and the adsorption type glass fiber separator does not need to supplement the electro-hydraulic during the service life.

 

 

 

Low self discharge: the grid made of special lead calcium alloy with good corrosiveness can control the self discharge at low temperature and store at 25 ℃ for half a year without charging.

 

 

 

< wide temperature range: the battery can be used in the temperature range of - 15 ℃ ~ 50 ℃.

 

 

 

Easy installation: it can be installed in vertical and horizontal way according to the requirements of users.

 

 

 

< long life design: the heavy-duty lead calcium alloy plate with corrosion-resistant structure is adopted.

 

 

 

Use and maintenance

 

Parameters

 

It can be used in the environment of -15 ℃ ～ +45 ℃, the recommended temperature is 25 ± 5 ℃, and it can be used in the environment of too high or low temperature, which will reduce the battery life.

 

◆ capacity and influencing factors

 

The amount of electricity that a battery can give under certain discharge conditions is called the capacity of the battery, expressed by the symbol C. The common unit is ampere hour, or ah. Usually indicated at the lower corner of C

 

Discharge time rate, such as C10, is the discharge capacity of 10 hour rate; C3 is the discharge capacity of 3-hour rate.

 

The capacity of the battery is divided into rated capacity and actual capacity. See Table 1-1 for rated capacity of SST series batteries. The actual capacity refers to the actual power output by the battery under certain discharge conditions, which is equal to the discharge

 

The product of electric current and discharge time, in ah.

 

The discharge capacity of the battery is directly related to the discharge current, the termination voltage and the temperature when discharging. In general, the lower the discharge current, the lower the termination voltage and the higher the temperature, the battery will discharge the electricity

 

The bigger.

 

◆ influence of ambient temperature on capacity

 

Temperature affects the capacity of the battery. Figure 3-1 shows the relationship curve between the discharge capacity (10 hour rate) and temperature of the battery; for example, the temperature is reduced from 25 ℃ to 0 ℃, and the capacity will decrease to 80% of the rated capacity

 

At the same time, the temperature is too low, which makes the battery charge insufficient for a long time, which results in the negative pole salinization, and eventually causes the battery to be unable to discharge electricity. If the temperature of the battery is not 25 ℃ when discharging, convert it to 25 according to the following formula

Capacity C25 at ℃.

 

Where: t-ambient temperature at discharge CT discharge capacity at temperature T

 

K-temperature coefficient, k = 0.006/ ℃ 3-hour discharge rate when discharging at 10 hour rate: k = 0.008/ ℃ 1 hour discharge rate: k = 0.01/ ℃

 

With the increase of the ambient temperature, the battery capacity will increase in a certain range, for example, the temperature will rise from 25 ℃ to 35 ℃, and the capacity will rise to about 105% of the rated capacity, but the temperature will continue to rise,

 

The increase in capacity is slow and will not continue to increase.

 

◆ DC power supply of power plant;

 

◆ DC power supply of substation (substation).

 

The main purpose of choosing the appropriate floating charge voltage is to achieve the ideal service life and rated capacity of the battery. If the floating charge voltage is too high, the floating charge current of the battery increases, which will cause grid corrosion

 

The speed and the water loss of the battery are accelerated, the service life of the battery is shortened; the floating charge voltage is too low, the battery can not be maintained in the full charge state, which is easy to lead to irreversible salinization, reduced capacity and shortened the battery

 

service life. During floating charging operation, the charging voltage shall be adjusted appropriately with the ambient temperature. The floating charge voltage value can be calculated according to the temperature compensation coefficient of -3.5mv/ ℃ / monomer. Similarly, the uniform charge voltage needs to be in loop

 

The temperature compensation coefficient of the battery charging voltage is -3.5mv/ ℃ / monomer.

 

 

In the process of repair, if there is the following phenomenon, the battery can no longer be used

 

(1) The temperature of battery shell (can be felt by hand) shall be checked frequently. If the local temperature is higher than the temperature of other parts, or if a cell electrolyte boils, the gas is seriously separated (even in daytime, white gas can be seen by a photo of the manual electricity with serious heating, which means that the inner plate of the grid has short circuit phenomenon.

 

(2) If the battery fails to charge for a long time (the voltage does not rise), the continuous charging time after sulfur removal repair is more than 10 hours, the charging is still not completed, or a local heating of the battery is serious, which may be caused by short circuit in the cell or the falling off of the plate. The tester must be disconnected. Check voltage and charge condition, battery with low voltage or low charge (no electricity storage) can not be used, or it needs more lasting repair time.
