What is the voltage and ampere rating of 4 batteries?

[LeKai]

4 batteries depend on the battery model, 6-dzm-XX, which means 12v per battery, so 4 batteries would be 4*12=48v, the number after -XX indicates the ampere rating (for example, 6-dzm-12 means the battery is 48v12ah. Another model is 8-dzm-XX, which means 16v per battery, similar to the above, 16v*4=64v, and 8-dzm-XX indicates the ampere rating). Here are some precautions for using car batteries: Remember to turn off the lights: For example, forgetting to turn off the lights during the day, especially the headlights, some beginners may turn on the car lights during the day and forget to turn them off after stopping the engine, which will drain the battery over time. Also, listening to music or using the air conditioning when the car is not started can also drain the battery over time. Pay attention to maintenance: To avoid the problem of a dead battery, it is important to maintain the battery properly. First, do not start the car frequently. The car also has a lifespan, and frequent starting will cause wear and tear. If the car doesn't start the first time, wait a moment before trying again, as continuous starting puts a lot of pressure on the car and increases discharge, gradually reducing the battery's lifespan.
