"sorry too newbie to post links!"
Very pleased definitely a vast improvement over HTC original battery, Plus for uk£17 you get:
2 x 1900mAh batteries
1 x Mains USB Charger & Stand alone charger
(Its not obvious in the lit but you can charge your 2nd battery while using the 1st)
anyway very pleased so far, sorry haven't got the time or inclination to do detailed study.
only query would be what specifically are the stats that get reset when resetting battery stats?
