This article discuses the status LED on the external battery charger included with battery only SPEEDCHECK-12 systems.
The following products are discussed in this article:
- SpeedCheck: SPEEDCHECK-12
Battery only SPEEDCHECK-12's do not contain a solar charging system and must be charged externally using the provided charger.
The external battery charger has an LED to alert you of the battery state of charge:
- Red = battery charging
- Green = battery is full and being maintained
Below is a rough guide you may follow for charging times based on battery state of charge:
|Battery Capacity||Battery State of Charge||Charging Time|
10% (~11.7V) to
|~10 to 11 hours|
Open Circuit Voltage (per cell) vs State of Charge
Age, temperature, state of charge, and cycle life will affect charging time and service life. The above charging times are estimations only.
Charging will continue once the green LED is illuminated. This means the charger has dropped into a very low current stage to maintain the battery's full charge.
Charger housing may be warm to the touch while charging.
