Instructions

Host

1. Battery State of Health

2. Indicator Status Description
   LED1 is on
   Indicating that the battery has reached the disposal standard, please replace the battery.
   LED2 is on Indicating poor battery life.
   LED3~5 is on
   Indicating that the battery is in good health,LED5 is the best, LED4 and LED are next.
   Note: Only one LED light will be on at any time.

3. The battery health status indicator will not light up when the device is just installed for the first time, until the car engine starts once or the device works over one hour.
   In this situation, the indicator represents an estimated test result. It will be more accurate when the device works for over 48 hours.

4. The device adopts intelligent learning algorithm, the longer working time, the more accurate result.

5. If disconnect and reconnect the device, the data in the device will be cleared, which is equivalent to the first installation.

Display

1. For the first time, short press the key “ ” to power on, then a fixed interface display will appear after power on.
   Note: If there is no response after pressing the key “ “, the built-in battery may be low, please use a 5V charger to charge it.

2. After power on, the display will automatically search for the host and establish connection, then the successful connection icon “ ” is always on, and the screen starts to display real-time data.

   • SoH shows 1 cell: Indicating that the battery has reached the disposal standard, please replace the battery.
   • SoH shows 2 cells: Indicating poor battery life.
   • SoH shows 3~5 cells: Indicating good battery life. 5 cells are the best, 4 cells and 3 cells are the next.

3. Press the key “ ” to switch the backlight mode.

   • Auto mode (default): Automatically turn the backlight on or off according to the brightness of the ambient light.
   • Power-saving mode: Turn off the backlight.

Fault Alarm Description

1. The LED1 on the host is on or display shows 1 cell SoH: Indicating that the battery has reached the disposal standard and should be replaced.
   Note: Due to different vehicle conditions, temperature etc., the battery may still be able to start the engine, but it is recommended to replace it.

2. The cranking system warning light on thehost is on or the icon ” ” on the display is on: Indicating low cranking voltage. It might be a cranking system failure or battery failure.

3. The charging system warning light on the host is on or the icon ” ” on the display is on: Indicating abnormal charging system. There may be cases such as high voltage, low voltage, or no charging in the charging system etc.

4. The low charge warning light on the host is on or the icon ” ” on the display is on: Indicating low battery level or the battery voltage is lower than 12V.
   Please charge.

5. The temperature warning light on the host is on or the temperature value on the display is higher than 60°C(140°F):
   Indicating high battery temperature. High temperature environment will accelerate battery life degradation.
