24V/12V/6V Battery Test BM550

SOH: Status of Health

SOC: Status of Charge

R: Internal Resistance

VOL: Battery Voltage


* Good. (The battery is in good condition, feel free to use)

* Normal. (General state of the battery may continue to use)

* Poor (The battery is in poor condition, Please replace it in time)

Intimate Protection

1. Poor Contact Prompt

When the test clip does not clamp the positive and negative electrodes of the the battery, the display will react.

2. Polarity Reverse Protection

When the polarity of the input power supply is reversed, it can protect the switching power from damage.

All values and CCA values can be converted as needed

Off-Car Test

To prevent battery failure, check the battery usage status in advance
