the charging problem

[Kira]

Hi
I go to work by E-bike every day!
Actually,my company is the E-bike battery and wheelchair battery charger-KUNSHAN ST chargers.
If anybody has some problem about charging,we can discuss together.

Perhaps someone can help me understand, on a non bike related topic, why the manufacturer of a replacement camera battery says to try and not to "part" charge. "Whilst these units have a non memory capacity doing so will reduce the long life of these cell types".

I usually charge the same as my bikes, when I return home. Keeping them topped up. Now I'm confused. What is the difference apart from size?

You shouldn't part-charge lithium batteries, because the balancing is done at the end of the charge cycle. If you part-charge, the balancing doesn't happen, so the cells go out of balance and you lose capacity.

Hi

a camera battery is typically only 1 cell nominal 3.6v whereas a bike battery is a collection of up to 10 cells in series. So the arguement about charge balancing is relevent to a bike battery but not relevant for single cell devices

The arguement s are different for different cell chemistries.
older chemistries eg Ni- mH. Did lose capacity if not periodically fully discharged and fully charged.


many mobile phones and similar electronic devices eg cameras mp3 players assume that the battery is fully charged each time they are inserted and calculates the remaining energy of the cell by the number of minutes it is in operation or the amount of charge pulled from it rather than measuring it's state of charge.
