I will start an test with MP3 192kbps CBR, Vol. 20 within the next 4 days. I'am a bit busy for now. Sorry.
At this moment the LiP385585 is the IONITYs only battery with 1900/2000mAh
In the H300 series you have to remove more parts than inside the H100 series. The front and rear panels are fixed with four clips each and it's hard to remove the front panel at the last steps.
The 3.8mm are more than enough. You can close the case safely but there is not an inch free space left between rear panel and battery. If you want to use an "thicker" battery (> 3.8mm) you have to remove the blue rubber mat between battery and hard disk.
No I didn't run the test with the original battery.
I've got very good connections to the management, insolvency practitioner and distributor. So I've got enough batteries in stock and I can get more if I need. For example when there will be an omnibus order from the US.
I've recharged the battery from flat (display: low Bat, player: off). I know that you can try to start the player again for about 10-30 mins after a couple of minutes.
1) I sell these batteries
2) Have a look at
www.dapstore.com
3) It's a bit harder as the H100 series
4) Yes. And the english version will be the first one. Pictures are ready
(online step-by-step slides will be ready within 2 days)
5) Original battery is an SKC LPCS355385 (3,5mm thick, 53mm width, 85 mm length) with an capacity between 1400 to 1500 mAh.
