I have Samsung YH-925 20GB Digiat Audio Player and the battery has had it. I'm looking at various websites offering replacements. Samsung are offering a 900 mAH 3.7 Volt battery for £51.99 = p and p which seems a bit steep compared to Amazons offer of 750 mAH li-ion for £12.95 or M90.co.uk's 1100mAh for £9.45 Is an 1100mAh better than a 900? Or will it blow my machine up. I'm afraid I have absolutely no idea. It was a relatively expensive machine, I like it and its got all my music on it - i don't want the faff of having to reload and learn to use a new one so I would rather pay £50 than buy a new machine, but if I don't need to I'd rather pay les.
