I understand the 1/10 capacity for 10 hours charging rate so no need for any comments on that please, but if the battery is partially charged, to an unknown state, how long should it be charged for. Is it still 10 hours, is there a possibility of overcharging and damaging the battery?

Oops, this should have gone into the Forum, not the how to section. Sorry. Can it be moved please?

(Sorry for adding a response here but you wrote it in the wrong forum. Its a wiki page and nobody can comment- Rudy)
