More Power and Ultra Power does not have the same use, but personally it does not talk to me, I never know where to take, you have every time I check ... it's annoying! With an expanded color band, my little brain easily save that for my remotes are gray, my wireless mouse or my low-consumption devices, and blue are geared towards the toys and other energy objects. The design of the affected devices affixed in front and not the back would also be welcome.

That said, I remain faithful to the brand for several years as the batteries do have more autonomy than the competition and that they do not leak.
