    So Once again I have another question ;). My battery lasts a
    Good 4-5 hours but noticed it takes 6-8 hours to charge 100%. Im running a battery calibration test and 3.5 hours has lapsed and battery was at 50% now only 90%. Charger is a oem panasonic. Battery is old but a problem with charing circuit or charger not outputting enough wattage?is this normal? Thanks again.

    That's completely normal... big batteries take big time to charge man. ESPECIALLY if it's on.

    Some times if my CF-30 battery is COMPLETELY drained, if I'm using it all day at work whilst charging obviously it won't even charge fully within an 8 hour work day...
