The newer batteries require FULL discharge during early use before re-charging to allow their 'memory' (gawd I hate this new tech crap) to ensure they fully charge the next time.


I suggest, if it isn't fully discharged, and you don't have a spare battery that you alternate, to BUY A SPARE BATTERY THAT YOU ALTERNATE!


I don't mean this nastilly, but you can either kill the one or alternate the two.
