LED Indicators

Autonomous Status Indicators:

Indication

Flash pattern

Battery status

Remark

No indication

Good

Battery is healthy and performing well

Steady yellow light for 1.5 second

Self-test when powering on

Battery operational after 1.5 second

Steady yellow light

Battery cell temperature out of range:
Too high temperature

Let battery cool before continuing operation

Battery cell temperature out of range:
Too low temperature

Make sure ambient temperature is within range
See Ambient Temperature

Too high discharge current to tool

Check the tool configuration
Remove battery from tool

Too high charge current

Remove battery from charger and replace charger

Invalid charger

Use appropriate charger
See Battery Charger Data in Safety Information found on ServAid

Too high voltage applied externally to battery connector

Use appropriate charger
See Battery Charger Data in Safety Information found on ServAid

Steady red light

Unrecoverable error

Replace battery

State of Charge (SOC) Indicators:

Press release button (1) to show SOC indication (2).

Indication

Battery charge

Remark

Full charge

Medium charge

Charge battery when possible

Low charge

Charge battery

Empty

Charge battery

When attaching the battery to the charger, the charging procedure will start and go on for 20 seconds. The charging is then temporarily stopped as the battery performs a self-test. The self-test continues for 10 seconds and after this the battery resumes charging again.

State of Health (SOH) Indicators:

SOH indicates how much of the original capacity that is left in the battery cells, that is, how much the battery has degraded since it was new.

SOH is not an indication of current battery charge.

When the button is pressed the battery SOH is shown, as listed below:

Indication

Flash pattern

State of Health (SOH)

1 flash, green

More than 80% of the original capacity

1 flash, yellow

Between 70-80% of the original capacity

1 flash, red

Less than 70% of original capacity

Manual Status Indicators:

When the release button is pressed for 20 seconds the current battery state is shown by the LEDs in position 3 flashing in sequence, as listed below.

Battery 14V (4211613002) with generation letter A and B is not equipped with a green LED. The green LED is instead indicated with red light, as described in Battery 14V LED Behavior.
