The Battery Pack with charger directly from Apple is of course the first consideration when it comes to compensation for the supplied primary cells. If one possesses but for example only the Magic Mouse, in the "Start-charge" but then good four months has persevered, one should perhaps also consider the further use of primary cells into consideration '
The deciding factor for purchasing the Apple Battery Charger has then not so much for the most part given the very small battery charger and the batteries. The charger is meticulously crafted, the batteries can be used easily and take, but hold firmly in place. Owner of the long cable of the MacBook power supplies can also use this cable to the charger; as opposed to the (old) USB Charger this is not prevented by a nose in the plug.
Whether the batteries deliver what they promise, only time will tell.
