I will try to discharge them completely and recharge to full

These look pretty nice and charge in a reasonable amount of time but the final voltage is only 8 volts when fully charged

Since the voltage is lower than 9 volts the device im using these in doesnt run all that long until the voltage drops below its minimum requirement

Also it would be nice if there was a sentence in the instruction sheet telling the meaning of the charging status lights apparently red charging and green charged

Now every few days i just pop one off the charger and swap it out
