Charging times; a table

[Billy1mate]

Am I missing something here, are you all trying to charge your batteries to 80% and not 100%?
At the risk of sounding an idiot, the way I understand it with Li-On batteries is, it is advisable to have 80% charge in a battery if it is going to be stored or unused for a period of time and not charged to 80% to use on a regular basis.

Yes, the gist of this thread is that batteries will last much longer if only charged to 80%.

To be more accurately; it is the amount of time the battery spends at 100% (4,2V per cell). If you charge it to 100% and start riding , it is not the same as leaving it for weeks at 100%!

Thank you for clarifying that for me, much appreciated.

I was waiting till I had some reasonable experience with the new charging times. My figures are pretty rough - I've just been going by the 5 bar indicators. So if 4 bars are showing after charging that could be anything from 61 - 80%; I do get an idea of how much charge that 4th bar has by my next ride ie I usually get to a certain place before I lose the 1st bar, then it was close to full charge.

To summarise, this is for the shimano E6002 charger which is 1.8 amp. The charging times given for this are 6 1/2 hours to 80% and 7 1/2 to 100%. What has been working for me is 4'30" of charge time for each % of battery that needs charging. Once it gets to 80%, it does indeed speed up. So my time of 4'30" (or 270 seconds) per % is only for charging up to 80%.
