 The sides of the extraction member may further be substantially straight, or may be curved. The outer and inner molds may have a variety of shapes, including substantially rectangular and substantially circular. An ongoing problem with rechargeable batteries is their general dependency on an external recharging unit, plug and AC socket, which are often unavailable when recharging is required. Whilst attempts have been made to embed North American style mains supply connectors within large battery assemblies, these require access to a US AC socket. Furthermore all such approaches require a geographic specific plug or connector. Our preferred embodiments provide an integrated and mechanically compact solution for small batteries that are suitable for enabling universal recharging from a general portable or desktop computing device in any territory. This provides a modern rechargeable battery solution in standard formats readily suitable for portable computing accessories such as input devices, digital cameras and media players.
There is substantial and diverse prior art relating to rechargeable batteries in general, both on custom battery formats and transformers with embedded sockets and connectors, some where the connectors fold or slide to reduce profile. There are also many examples of recharging cradles for holding a plurality of batteries that connect either to a mains supply or in some case via a cable or directly to a USB connector or for custom batteries (such as a mobile phone). Various prior art exists on mechanical methods of collapsing the two flat prongs forming a North American mains supply socket, either to reduce format in a transformer or to store within a large format battery such as a C or D type.
By way of example U.S. Pat.
