In the main there is some thing which tells one the state of charge, be it an electric bike, or a phone recharging pack, however not all, the rechargeable touch, and rear lights for my bike have nothing to say ¼, ½, ¾ or fully charged, clearly one knows when fully discharged. Some items like my battery drill say fully charged on charger other items say nothing.
Reading the instructions for electric bike unlike lead acid it should be stored 60% charged.
Instructions like don't charge when unattended, can't really see how one can comply with that when it takes 6.5 hours to charge, it would be like watching paint dry.
400 Wh (11Ah at 36 volt) is a fair bit of energy so I suppose if it goes wrong it can do a lot of damage, as to if best charged in garage where if it goes on fire damage is limited, or in the house where if it goes on fire you see what has happened and can react to it, I don't know?
As to bike tail light, plugged in and taking 0.03A, then it went to 0.25A and then fell to 0.6A so I assume it is charged and will light for rated 6 hours, had I not got a USB amp/volt meter I would not have a clue when charged. Just a green LED to show charging which does not go out when complete, and all instructions in German.
I have had batteries become blotted in phones and dumped then, and batteries fail completely and fail to give high current output, since moving from NiCad to Li-ion I have in general treated the new just like the old, rechargeable AA cells going in the same charger. However maybe that's wrong?
Reading Wikipedia it seems Li-ion is not a single battery type, it gives LiCoO2 etc. However look on my equipment and batteries it just says Li-ion not LiFePO4 or any other ID as to what type. So how should we treat these devices?
Well my rear light is now drawing zero current and green light has gone off, I assume charged, English instructions would be nice, even Welsh instructions as sold in Wales, but German instructions are totally useless to me.

With a new pack costing around £300 clearly one wants to follow the instructions, Li-ion batteries is seems need different storing and using to the old lead acid, in my PC the battery is always kept fully charged the e-bike is first time I have seen it recommended not to either fully charge or fully discharge the battery to store. Old Ni-iron was fully discharge to store.Bosch e-bike instructions said:Recharging the Battery Pack prior to and during Storage
When not using the battery pack for a longer period, charge it to approx. 60% (3 to 4 LEDs lit on the charge-control indicator 3).
Check the charge condition after 6 months. When only one LED of the charge-control indicator 3 lights up, recharge the battery pack again approx. 60 %.
Note: When the battery pack is stored discharged (empty) for longer periods, it can become damaged despite the low self discharging feature and the battery-pack capacity may be strongly reduced.
It is not recommended to have the battery pack connected permanently to the charger.
