Bushfiva,
I should have thought about looking for the manual on the web. I downloaded it and will have a look. As far are batteries are concerned, I keep charging them for a long time (12 hours or more) before first use and I repeat that a couple of times. And I always charge the battery when it is around 15%. My 4 year old Finish branded phone battery still lasts 4 days despite me talking a lot. Maybe I am overcautious.
I will have a look on the article. Thanks.
