Hello all,

Thank you in advance.

I found this

http://www.the-digital-picture.com/Reviews/Canon-LP-E4N-Battery-Pack-Review.aspx

Which suggests that it will only charge to about 90% with the charger you & I have, A newer charger will be required for 100% My calculator says that instead of getting 2450 mAh you' be hoping for 2205 mAh which is a bit shy of the correct battery we're already using.

If then, the battery is not fully charged, can we presume that it not last as long in terms of years?

I really don't know whether it would or not. It certainly won't make it last longer but whether it would shorten it's life much is hard to tell.
