If you have older V1 or V2 SmartSpeed Pro timing units a multiple charge cycle is recommended to protect the batteries.
Note: a multiple charge cycle is not required for current SmartSpeed Pro timing units V2.1.
To complete a multiple charge cycle:
- Charge the units until the LED is solid red; then
- Unplug the units and plug them back in; and
- Charge the units again until the LED turns solid red.
- Avoid leaving units on charge for too long as this can damage the batteries.
