At this time of year we all tend to start sending gifts,be careful if send them via Royal mail if the contain batteries, it is possible the item may get destroyed, or returned and you can be fined,the Royal mail have a complex and confusing leaflet all about what you can and cannot send,if your packet contains batteries you must declare it when posting at the post office, they scan the packets at sorting offices and if there is no sticker on the packet stating there are batteries,the package will be destroyed,in the leaflet you cannot send new or used Lithium batteries if they are not sent with a electronic device,there is also a limit on how many batteries can be sent with a device,so check with the post office before you send
