Car batteries should be inspected and maintained regularly

During the operation of the vehicle, it is particularly difficult to maintain a reliable charge and discharge balance of the vehicle electrical system due to the increased power of the engine at the start of the low temperature cold start and the complicated electrical equipment equipped in the vehicle. This situation is even more pronounced when driving in urban areas. During the parking process of the vehicle, due to the self-discharge effect of the battery itself and the sleep current required by the control unit such as theft prevention, the battery always has a certain current consumption. Long-term parking of the vehicle without charging will result in damage to the battery. The characteristics of the battery determine the periodic inspection and maintenance, as follows:
  1. Check the liquid level of the electrolyte regularly according to the manufacturer's instructions. If necessary, add distilled water to the ** mark.
  2. In order to reduce the self-discharge of the battery, the outer surface of the battery should be kept clean and dry.
  3. For normal use vehicles, the electrolyte density or open circuit voltage of the battery should be checked regularly. When the electrolyte density is lower than 1.2g/ml or the open circuit voltage is lower than 12.3V, the battery should be recharged to above 12.7V.
  4. If the vehicle is idle for more than two weeks, it is recommended to disconnect or turn off the battery main switch; if it is idle for more than two months, the battery should be removed.
  5. The battery should be stored at a temperature above -10 ° C and below 35 ° C, at least once every three months.

Fan Finger Guard, also is known as Fan Guard. 

Fan Finger Guard can protect the AC/Dc Cooling Fan, ensure the air flows freely wile keeping objects safely away from the fan blades, and durable, all-metal construction for long term reliability and safety. Extended service life. Reduce the failure rate.

There are many ways to differentiate the fan finger guards.

1. According to the material, the fan finger guards can be divided into metal finger guards and plastic finger guards.

2. According to the size dimension, the fan finger guards can be divided into finger guard for 30 mm fan, 35 mm fan, 40 mm fan, 45 mm fan, 50 mm fan, 60 mm fan, 70 mm fan, 80 mm fan, 92 mm fan, 120 mm fan, 135 mm fan, 150 mm fan, 172 mm fan, 180 mm fan, 200 mm fan, 220 mm fan, 254 mm fan.
