What should I pay attention to when using the battery?

Batteries have self-discharge. If they are left unused for a long time, energy will be lost, so they need to be charged and discharged regularly. Engineers can judge whether the battery is good or bad by measuring the open circuit voltage of the battery. Take a 12V battery as an example. If the open circuit voltage is higher than 12.5V, it means that the battery has more than 80% energy storage. If the open circuit voltage is lower than 12.5V, it should Recharge immediately. If the open circuit voltage is lower than 12V, it means that the battery stores less than 20% of the electric energy, and the battery may be unusable. The maintenance-free battery adopts an absorption electrolyte system, so no gas will appear during normal use. However, if the user uses improperly and causes the battery to be overcharged, gas will appear. At this time, the internal pressure of the battery will increase and the battery will be affected. If the pressure valve on the top opens, it will cause the battery to swell, deform, leak or even break. These phenomena can be judged from the appearance. If the above situation is found, the battery should be replaced immediately. When starting the battery jumper, you should pay attention to the following issues: It should be confirmed that the rated voltage of the batteries of the two vehicles are the same, and the capacity (Ah) of the power supply battery should be greater than the capacity of the depleted battery. If there is no suitable power supply vehicle, you can also use a separate battery to supply power; do not disconnect the positive and negative connecting wires of the depleted battery from the vehicle; seal all the electrical equipment in the depleted tram. It should be noted that because jumper starting is required to use jumper cables, most car owners usually do not have such equipment. Therefore, if the vehicle cannot start or can not drive normally due to the exhaustion of the battery, please solve and replace it in time!
