fourbanks Posted September 10, 2011 Author Report Share Posted September 10, 2011 Well the batteries arrived ok the only thing different to the Sony battery is that you have to cut off the green plastic protective layer as the battery is just a fraction to large is that correct does anyone know ?

jim.hoggarth Posted September 10, 2011 Report Share Posted September 10, 2011 Hi Nick. Yes, usually. I have a recorder in for repair now with one of these gumsticks 'in the slot'. The top of the green outer has been cut away at the positive end, and replaced with thin insulating tape. Obviously a common problem, as I have heard of this before. The excess of plastic can prevent the contact strip making with the top of the battery - the contact comes from the side, across the thin edge and onto the contact 'pip', rather than coming at the battery from 'above' the contact, if you see what I mean. Must be very frustrating for users with no mechanical bent as they will just assume the batteries are crap and complain to the seller. And that could be another MD user lost to the iPoo. I have never used these batteries myself, always prefering the Pisen brand from HK. Jim Quote Link to comment Share on other sites More sharing options...

Jim hI JIM Thanks i wasn't sure if i should have removed the whole wrapper leaving just the bare metal or just remove just one end of the wrapper The battery appears to charge ok but drops a bar in the first 15 minutes so i will address this thread again at some point with my further findings Quote Link to comment Share on other sites More sharing options...
sfbp Posted September 10, 2011 Report Share Posted September 10, 2011 The battery appears to charge ok but drops a bar in the first 15 minutes so i will address this thread again at some point with my further findings Most NiMH batteries need at least 3 full charge/discharge cycles before they will behave.

Many thanks for your knowledge in this field The Sony battery is very hard to find that and with no help in their forum it's a wonder anyone buys anything Sony in the first place there service in the UK is very poor Having said that the service of all the main players is poor except for denon In the old days I use to hang around with all of the main Japanese chairman and directors when they were in London sharing of ideas and in general promoting Hi-Fi at its very best Today however everything has changed the spark has gone out and the future uncertain for all of Japan which is a tragedy for all I just paid Quote Link to comment Share on other sites More sharing options...
