Ok so let me ask this ?
The charger has a default safty timer which will not allow it to charge more than 16 hours.
If you are leaving this from lets say 3:00::PM until 11:AM THE NEXT DAY , THIS IS 20 HOURS.
So the charger may be timing out insted of charging completely ?
So today when you plug it in ,
1. Check the entire pack Voltage Before plugging charger up
2. Check every hour or so to see if charger has shut off
3. As soon as charger shuts off Check Pack Voltage
4. wait 1 hour then check pack Voltage again
If it has dropped much (1 Volt) check each battery
** if charger is still on and only shuts off after Timeout

** are these batteries

More info ------------------
Misc. Info

Voltage on a fully charged battery in good condition will read 2.12 to 2.15 volts per cell (about 12.75 volts for a 12 volt battery, or 6.40 for a 6 volt)


Specific Gravity Readings to determine State of Charge:

12.75 & Above = 100% Charged
12.60 to 12.74 = 85 to 100% Charged
12.40 to 12.59 = 75 to 85% Charged
12.20 to 12.39 = 50 to 75% Charged
12.00 to 12.19 = 25 to 50% Charged
12.00 & Below = Fully Discharged


In both voltage and specific gravity readings, consistency among cells and among batteries is important.
