▲▲▲TIPS:

• If both the two LEDs on the Car Data Saver lights green, the charge level of this storage battery is high enough.
• If a LED on the Car Data Saver lights green and another LED lights red, this storage battery is not high enough and needs to be charged before it can be used as a temporary power source, or you can use another 12V storage battery which is high enough as a temporary power source.
• Disconnect the car's storage battery ( which is to be replaced ) from the car while remaining the connection between the car and the Car Data Saver, which is with the storage battery of temporary power source. Then connect a new storage battery to the car, make sure that the polarity connections are correct.
• Disconnect the Car Data Saver from the car. Then disconnect the Car Data Saver from the storage battery of temporary power source.
