This is a genuine high capacity battery, as supplied by the manufacturer in the original handset.
The battery has been removed from the original handset and it will need
to be charged fully in the new handset before first use, preferably overnight. We recommend that you do this for the next few subsequent uses as well.
Please do not hesitate to contact us via eBay message if you have any problems whatsoever. We are happy to provide help, advice and resolve any problems.
