Ebay UK item number 171279008589 or similar

Pictures tell how to ....... Available on ebay less than a fiver

Have to admit to buying it - received today - tested - working on standard discs, not working on HiMd, opened up the unit and cleaned and lubricated the worm drive (laser sled). Happily playing HiMd discs now. Real bargain

No - The contacts are underneath the sliding, spring loaded shutter on the flat side of the battery - just push it (the shutter) down, insert battery in charger and charge.

I've used this type on these batteries to good result - ebay uk item number 371476115125 and 400783254728 also 381452941610

The 14650 was higher capacity - but this causes no problems - a side benefit is longer playtime. - Also battery was quoted as having protection built in - however, I didn't bypass the existing circuit in the empty case - just inserted the new battery.

Battery - Lip-8 contains a very standard 14650 (and readily available) battery - easy to fit in the empty case - I just worked a blade around the seam, separated the case and pulled off the spot welded terminals with care (snipe nosed pliers did the trick for me). inserted new 14650 and reassembled the case around it (a snug fit, the lack of solder tabs didn't pose a problem). - Usual disclaimer about safety - Please note that I am only describing what I did, not how to do it yourself - Lithium batteries need special care.

Hi - to answer the two questions... 1. The replacement battery has its own built in protection PCM and the functions continue to work as normal 2. Because the battery already has its own protection module, it is not strictly necessary to use another (effectively putting two protection circuits in series), but no harm in trying (I have done this series arrangement in a JVC XM-R70SL and it works fine) Regards

Great fix Jimma - well documented - that's the RH1 and NH1 sorted for another few years! - nice to see it done without having to take the machine apart too.

Howardvu - Thanks for your kind feedback, I am so pleased that you found it useful - You are absolutely right to note that only the scroll wheel needs to be removed........just needs a little more care in wielding the soldering iron in the confined space - did another myself a couple of days ago in the way you suggest. The N10 is one of the best players Sony made and it's a shame to see them consigned to the history books.

Hi - The battery I used is just a brand new generic one, not made for these players specifically - the battery I sourced has the same specification as the Sony original, just a slightly different dimension - if you search ebay, I'm sure that you'll find them. Yes, (because the battery is new) they hold a full charge for a long time. The original batteries are no longer available and as you say, Sony stopped production years ago - so many of the batteries fitted are at the end of their useful life. These generic batteries will fit the E10 too.

Finding and fitting a replacement battery for the MZ-N10 needs a little electronic awareness and a bit of luck - the battery in the N10 is listed as having 3.5mm thickness and is 3.7v at 350mah - On ebay UK is listed item number 181291308343 which has the right dimensions to fit and the right rating except that thickness is listed at 4mm. Anyhow here is the successful result - the ebay sourced item has a paper label that needs to be removed (easy) to allow it to fit readily. Things to note:- 1. Turn off the internal battery switch then remove the screw holding the scroll wheel in place 2.Open the MD lid, then remove the scroll wheel and ribbon cable complete (watch how the connector lock works) 3. Remove the back cover by taking out the remaining three screws - lift off (scroll wheel edge first). 4. Remove the battery ribbon cable from its connector (lift the cable lock) then remove the battery. 5.Insert the new battery taking care to orient it with the leads correctly positioned 6 Carefully solder in the battery wires to the test points behind the battery connector - making sure of polarity 7 Assemble and test Attached are some snaps of the process (the fine tipped battery powered soldering iron came from Maplin) See here for photos (admin). Same thread, later post!

More for the scrappad - the venerable MZ-1. The original BP-1 batteries are mostly deceased now and had limited capability. One rough and ready solution is to acquire a couple of lithium rechargeables type 14650 and an appropriate charger (available on ebay for around £10/$15/15euro the lot). Find some high density polystyrene and use a hobby knife to cut out three blocks (two for shimming and one to hold the home made end connector). Double sided tape will hold the shims in place. Fashion an end connector to sit in the battery doorway and provide contact/pressure - a couple of brass paper fasteners will do as well as anything.(Push them through the polystyrene and join them together at the rear) The result - a functioning portable player with no damage or modification. Lithium batteries need special care over charging - so a word of warning - Never plug in the MZ-1 charger while lithium batteries are inserted - it can be a dangerous thing to do. Never short the batteries and always check polarity when inserting. Pictures should be self explanatory. Enjoy the resurrection of the dinosaur!

Personal experience only here, both MZ-R2 and MZ-R3 can often suffer from weakened laser read suspension, leading to intermittent ability to read/play discs - there is a workaround fix, but it is tricky to do. MZ-R5ST is really a very good acquisition indeed and the R30/35/50 derivatives are very reliable too.
