After a full charge of 16-20hrs transponder should run flashing green for at least 8 hours.
Less than 8 hours indicates the battery should be replaced.

Further info

This transponder is designed for club and track ownership and used in all types of Remote Control model car racing. The internal battery is a rechargeable type and will last for many years if cared for correctly. Eventually the transponder battery wears out. This is indicated by the transponder not running at all. It is advised that if the RC transponder will not run flashing green for at least 8 hours then it is time to have the batteries replaced. Failing batteries can leak chemicals and internally damage the transponder without showing any signs of damage externally. So we recommend not leaving it too long before you have the battery replaced. We recommend the AMBrc racing transponder be fully charged and discharged at least once per month to maximise the battery life. Do not over charge. Once the charging light changes to green the transponders should be removed from charge. Transponder batteries in good condition can run green for up to 20 hours or more. AMB Mylaps do not make or supply this type of transponder anymore. The AMBrc transponder is fully compatible with AMBrc2, AMBrc3, Mylaps RC and Mylaps RC4 decoders.
