German industrial standard: Deutsche industrie normung, its English name is German DIN standard battery, lets take the model number of 54434 battery as an example, which is described as follows:
1. If the model number starting with 5 indicates that the rated capacity of the battery is less than 100 AH. The beginning 6 indicates that the battery capacity is between 100Ah and 200Ah. Starting with 7 indicates that the rated capacity of the battery is greater than 200Ah. For example, the rated capacity of 54434 batteries is 44Ah. The rated capacity of the 61017MF battery is 110Ah. 70027 The rated capacity of the battery is 200Ah.
2. The two digits number behind the capacity indicate the battery size and group number.
3.MF indicates maintenance-free.
4. The American standard battery can also be expressed in this way :78-600,78 indicates the battery size group number,600 indicates that the cold start current is 600A.
Note: â‘ Cold start current (CCA): The minimum current in a particular sense that can be obtained under the conditions of -17.8C and -28.9C. This index relates the starting capacity of the battery to important variables such as engine displacement, compression ratio, temperature, starting time, technical status of the engine and electrical system, and the minimum service voltage for starting and ignition. It refers to the minimum current that a fully charged 12V battery can supply when its terminal voltage drops to 7.2V within 30s. The cold start rating gives the total current value.
(2) Reserve capacity (RC): the car in the charging system does not work, at night by battery ignition and provide minimum circuit load can run the approximate time, can be specifically expressed as: fully sufficient 12V battery, Under the condition of 25+2℃, the discharge time at 25A constant discharge until the terminal voltage of the battery drops to 10.5±0.05V.
