Tried to get in relevant electronics markets a spare battery. not in stock; would have to be ordered as spares only allegedly. Decided on the reviews, to order this. Power cable, unfortunately really a bit too long (otherwise you always complaining about too short cable) and difficult to accommodate in the housing. Fully charged before first use. No long-term rating possible because only a short time in use. For now ordered a battery pack to test this. If OK, then another order for the other devices. Highly recommended for the price in any case. Jan.2015 Addendum: Unfortunately not as good. Capacity display in the phone always full. Already at the call display to zero and phone went out. Have purchased from another manufacturer new. Slightly more expensive. Now, however, fully satisfied.
