理士蓄电池DT876属于8V170Ah动力型蓄电池，广泛应用各种电动巡逻车、观光车、高尔夫球场电瓶车、游览车等以电瓶作为动力源的车辆，具备超长的设计寿命，失水少，维护少，爬坡动力强，行程长等特点。广州贝朗斯*批发各种动力电瓶， 蓄电池作为一种新的电力能源，投入使用后，必须定期地进行充电和放电。充电是使蓄电池贮存电能及时地恢复容量，以满足用电设备的需要。放电是要及时地检验蓄电池容量参数及促进电极活性物质的活化反应，蓄电池充电和放电状况的好坏，将直接影响到蓄电池的电性能及使用寿命。 LEOCH理士蓄电池DT876这款8V系列的电瓶，日常使用需要补加蒸馏水， 蓄电池的外部表面检查应该是经常性的，一般来说，首先要检查蓄电池及各极柱导线夹头的固定情况，应无松动现象；其次检查蓄电池壳体应无开裂和损坏现象，极柱和导线夹头应无烧损和氧化，否则，应将蓄电池从车上拆下修复；第三，应经常检查蓄电池盖上的通气孔是否通气，若蓄电池盖通气孔被堵，会影响蓄电池的正常工作，同时也会影响蓄电池的正常充电（可能产生的气体排不出去，导致电解液膨胀把蓄电池外壳撑破）从而影响蓄电池使用寿命。 拆装LEOCH蓄电池时需要分辨蓄电池的正、负接线柱，一般有以下几种方法：
　　⒈根据蓄电池上正和负标记识别 蓄电池上铸有“+”（或P）的接线柱为正接线柱，有“-”（或N）的接线柱为负接线柱。
　　⒉根据蓄电池接线柱所涂颜色分别 蓄电池正接线柱涂红漆，负接线柱涂黑漆。
　　⒊而对于没有正、负标接线柱记又没有涂颜色的蓄电池可采用下面几种方法
　　a.看接线柱的粗细，粗一些的锥形接线柱为正极，细一些的为负极。
　　b.看接线柱的自然颜色，呈深褐色的为正接线柱，浅灰色的为负接线柱。
　　c.看接线柱的表面硬度，用螺丝刀在接线柱表面轻划，较坚硬的为正接线柱，反之为负接线柱。
　　d.用万用表检测。有的蓄电池没有任何标记，或者蓄电池使用长久、标记被腐蚀损坏、辨别不清。把万用表置直流电压20V挡，红表棒与黑表棒分别接触蓄电池的两个极桩，如果显示的数值是“+”值，则红表棒接触的是正极，黑表棒接触的是负极，如果显示的数值是“-”值，则红表棒接触的是负极，黑表棒接触的是正极。
　　二、理士电瓶电解液液面高度的检查
　　一般汽车行驶1000km，冬季行驶10～15天，夏季行驶6天，应检查蓄电池液面高度。电解液液面高度应高出极板10～15mm。
　　电解液不足应及时添加蒸馏水，如果是因为电解液溅出而导致液面降低的，应该补加相应密度的电解液，并重新充电调整。电解液液面高度的检查方法如下：
　　⒈用玻璃管测量法
　　⒉观察液面高度指示线法 透明塑料容器的蓄电池，容器壳体上刻有两条指示线，指示*高液面和*低液面。正常液面高度应介于两线之间，低于中线则为液面过低，应添加蒸馏水补充。
　　⒊从加液孔观察判断法 部分进口轿车在电解液加液孔内侧的标准液面位置处开有方视孔，用于检视液面高度，若液面在方孔下面为液面过低；正好与方孔平齐时为标准；液面高于方孔为过多。
　　当电解液液面低于标准时，应及时补充蒸馏水，不能加注冷开水、自来水、河水及其他质地的水。除确知液面降低是由电解液溅出所致外，不允许补充硫酸溶液。这是因为电解液液面正常降低是由电解液中的蒸馏水电解和蒸发所致。
　　三、LEOCH蓄电池电解液密度的测量
　　⒈非密封式蓄电池电解液密度的测量 对于非密封式蓄电池，可用吸管式密度计进行测量电解液密度。
　　电解液的密度大小是判断蓄电池容量的重要标志：
　　⑴冬季气温低于-40℃地区， 充足电时电解液相对密度为1.31 g/cm3， 放电25%、50%、75%和全放电时电解液相对密度为别为1.27 g/cm3、1.23 g/cm3、1.19 g/cm3和1.15 g/cm3。
　　⑵冬季气温高于-40℃地区， 充足电时电解液相对密度为1.29 g/cm3， 放电25%、50%、75%和全放电时电解液相对密度为别为1.25 g/cm3、1.21 g/cm3、1.17 g/cm3和1.13 g/cm3。
　　⑶冬季气温高于-20℃地区， 充足电时电解液相对密度为1.27 g/cm3， 放电25%、50%、75%和全放电时电解液相对密度为别为1.23g/cm3、1.19 g/cm3、1.15 g/cm3和1.11 g/cm3。
　　⑷冬季气温高于0℃地区， 充足电时电解液相对密度为1.24 g/cm3， 放电25%、50%、75%和全放电时电解液相对密度为别为1.20 g/cm3、1.16 g/cm3、1.12 g/cm3和1.09 g/cm3。
　　⒉有内置式密度计的免维护蓄电池电解液密度的测量 对于密封式的免维护蓄电池，特殊的温度补偿密度计。密度计上部有一个透明玻璃棒，棒下连接一个小盒，盒子内部有一个绿色小球，当电解液的密度约为蓄电池额定容电65%时，绿色小球就会浮起，升至小盒顶端，顶住玻璃球下端，可以看见密度计的中央出现一个小绿点。检测时，如果看到绿点，说明蓄电池的电量已经很足。如果看不到绿点或只是一片黑色，说明需要给蓄电池充电。 Leoch battery DT876 belongs to the 8V170Ah batteries, widely used in electric cars, sightseeing cars, golf car battery, car battery as a power source to tour vehicles have long life, less water loss, less maintenance, climbing power, characteristics of long stroke etc.. Guangzhou Bei Langsi professional wholesale all kinds of power battery, battery as a new energy power, put into use, must regularly charge and discharge. Charging is to make the battery storage capacity in time to restore the capacity to meet the needs of electrical equipment. The discharge is to test the battery capacity parameters and to promote the activation reaction of the electrode active material in a timely manner. The charging and discharging of the battery will directly affect the electrical performance and service life of the battery.
The 8V series DT876 leoch battery battery, daily use needs adding distilled water, the external surface check the battery should be frequent, generally speaking, we should first check the battery and the pole wire clamp is fixed, there should be no loose phenomenon; then check the battery housing should be no cracking and damage phenomenon, pole and the wire clamp should be no burning and oxidation, otherwise, the battery should be removed from the vehicle repair; third, should always check whether the battery cover vent ventilation, if the battery cover hole is blocked, will affect the normal operation of the storage battery, but also affect the normal charging of battery (gas may have discharged out the expansion of the battery case, cause electrolyte burst) thus affecting the service life of the battery.
When removing the battery, the positive and negative terminals of the battery need to be distinguished:
The battery positive and negative battery according to mark recognition on the cast of "+" (or P) of the terminal to the positive terminal, "-" (or N) of the terminal to the negative terminal of the battery.
According to the coated battery terminal of battery positive terminal colors were daubed with red paint, negative terminal black paint.
No, for the positive and negative terminals and no written standard battery color can adopt the following methods
A. look at the thickness of the terminal, some of the thick conical terminal is positive, some of the thin anode.
B. look at the natural color of the terminal, a dark brown for the positive post, light gray for the negative terminal.
C. look at the surface hardness of the terminal, with a screwdriver on the surface of the light column, more hard for the positive terminal, and the other is the negative terminal.
D. multimeter detection. Some batteries do not have any marking, or the battery is used for a long time, the mark is damaged by corrosion, distinguish not clear. The multimeter of the DC voltage of 20V block, the red bar and the black bar are respectively in contact with the battery two pole pile, if the displayed value is "+" value, while the red bar contact is positive, the black bar contact is negative, if the displayed value is "-" value is the red bar contact is negative, the black bar contact is positive.
Two, leoch battery electrolyte level check
General car driving 1000km, 10 to 15 days in winter, summer driving for 6 days, should check the battery surface height. The liquid level should be higher than 10 to 15mm.
Lack of electrolyte in time to add distilled water, if it is because of the electrolyte spill caused low liquid level, adding electrolyte density should be appropriate, and re adjust the charging. The examination method of the liquid level of electrolyte is as follows:
Measurement method for glass tubes.
The observation of liquid level indicating battery line method transparent plastic container, the container body engraved with the two line, indicating the highest level and the lowest level. Normal surface height should be between two lines, lower than the middle line is the liquid level is too low, should add distilled water supplement.
Come from the observation of the liquid adding hole judgment part of imported cars is provided with a square in the standard level of electrolyte inside the liquid adding hole at the hole, to examine if the liquid level height in square hole below the level is too low; when Pingqi coincided with the square hole as the standard; the liquid level above the hole too much.
When the electrolyte level is lower than the standard, should be promptly added distilled water, can not add cold water, tap water, river water and other texture of water. In addition to known level is lowered by the electrolyte spill caused by external, not allowed to add sulfuric acid solution. This is due to the normal reduction of the electrolyte level is caused by electrolysis and evaporation of distilled water in the electrolyte.
Three, battery electrolyte density measurement
The measurement of non sealed battery electrolyte density in a non sealed battery, measuring electrolyte density Straw type density meter is available.
The density of electrolyte is an important sign to judge the battery capacity:
The winter temperature lower than -40 DEG C, adequate electricity when the electrolyte density 1.31 g/cm3, 25%, 50%, 75% discharge and discharge when the electrolyte density were 1.27 g/cm3 and 1.23 g/cm3, 1.19 g/cm3 and 1.15 g/cm3.
The winter temperature is higher than -40 DEG C, adequate electricity when the electrolyte density 1.29 g/cm3, 25%, 50%, 75% discharge and discharge when the electrolyte density were 1.25 g/cm3 and 1.21 g/cm3, 1.17 g/cm3 and 1.13 g/cm3.
The winter temperature is higher than -20 DEG C, adequate electricity when the electrolyte density 1.27 g/cm3, 25%, 50%, 75% discharge and discharge the electrolyte relative density was 1.23g/cm3, 1.19 g/cm3, 1.15 g/cm3 and 1.11 g/cm3.
The winter temperature is higher than 0 DEG C, adequate electricity when the electrolyte density 1.24 g/cm3, 25%, 50%, 75% discharge and discharge when the electrolyte density were 1.20 g/cm3 and 1.16 g/cm3, 1.12 g/cm3
