I disagree with this. I know that a lot of manuals state this - but as far as I can tell, there is no technical reason for an extended 'first charge'. There is no difference between the first charge and the 10th as far as the battery is concerned. It has nothing to do with extending battery life or anything.
There may be an issue with the voltage sensing/software calibration - in that it may take some time for the software to determine the full charge voltage. Since these batteries are basically wired in, I doubt that would be a problem here. Why would the software need to calibrate? However - this might be a problem on my system as the gauge says it is fully charged, when it does not seem to be. Perhaps a few more charge/discharge cycles will fix that.
Li-Ion batteries are pretty good - but there are a few issues with them. They should not be left at full charge - it severely decreases their expected life. Also - they have a limited (and fixed) number of cycles. I have been 'topping up' my PB302 every few days - perhaps I should wait until it is more discharged before I apply the charger?
