First indications are that it meets its requirements and holds its power OK.
Nothing at the moment.

Bradford GB
It is too early to comment on battery life hence a 5 (middle) rating. You need longer than 5 days to determine if a battery will hold its charge, it needs calibrating 1st.
Power rating is based on limited use so far.
So far so good, stated life after 1st full charge 2hr 10m, after second full charge 5hr 15m, both without load/heavy use.
Fit is good
Delivery good
Price good value
Colour black, slight different texture to original battery but it's underneath
None really noted....yet
