It will start to self discharge like the others in about 10 days and slowly discharge as the
batteries don't like to be fully charged when stored.
The
batteries may get warm as they discharge and is normal.
By pressing the
battery button to check the charge you reset the 10 day timer and they won't start discharging again until that time has passed.
Check the
batteries about once a month and when the charge gets to 1 LED, charge them up to the third LED and let the
battery sit again.
If the
battery goes completely dead, it may not come back to life as it needs a little power for the chip inside to monitor the intelligent
battery.
