Hi guys, my very first post here. Cut things short I'm from the UK and just recently bought the MZNH900 mini disc player from amazon.co.uk (£69) Happy with the player and software managed to get all my tracks. The problem I am having is with the life of the battery (or playback time or what ever it is called) I am using the Sony rechargeable NH -10WM 1.2V 900mAh(MIN) battery that comes with the player. I want to know is how can I can i get the suppose 37 hours out of the rechargeable battery? Are there any other rechargeable battery's out there that I can get to increase the playback time? Because at the moment I am getting only 10 hours with the rechargeable battery and 19 hours with the LR6 external battery (total 29 hours) when recorded in Hi-LP Final question is if I but another rechargeable battery with a bigger capacity does that mean I will have to but a power adaptor for it as well. Thanks. Looking forward to your response.
