I'm looking to replace my battery in my 18 year old aiwa mini disc player if anyone knows where i can get one i would be most grateful
it's a 3.7 volt sometimes known as a gumstick battery
thanks

The company was taken over by sony for servicing but that is all the battery is exclusive to this model only which was the top model in it's day

The sound quality easily surpasses anything on the market today hence i would like to keep it if possible

Can you show us a picture of the battery itself?

Point of order, it's not 18 years old. There WERE no proper portables back then.

It's an LIB-902. Lots of posts on here about this battery, try googling it site:sonyinsider.com

Good point, according to this website it was released in October of 1999.

well you won't believe this but the extension battery pack is now working with a aa battery only
However after a period of 2 hours it stopped working with the message on the screen no adjust
does anyone know what that means and if theirs a fix
thanks

[fourbanks]

i have a local dealer and for £40 will try and fix it and will report back as and when

I have a few of these batteries, I am sure. What state they are in I don't know. I remember selling a couple of decent working ones to a guy two years or so back, but whether I have any good batteries left I am unsure. I don't do much with these recorders anyway, most of them come up with the dreaded 'NO ADJ' error I haven't been bothered finding out what causes it. At least not yet. I was toying with the idea of getting rid of all my early Aiwa stock anyway, or I may just keep it in case parts are needed in the future. Perhaps if the service manuals for Aiwas were readily available I would have more time for them, models such as the F65, F75, F80 etc. They are actually very nice machines - they remind me a lot of the Sony R55, which I do like very much.

If you haven't found a suitable battery yet, give me a shout and I will dig out the Aiwa box from storage.

many thanks Jim i have sent you a pm

I think we need to find out what that NO ADJ error code means first as without getting that fixed in what is a very unused player despite it's age it wont be much point in getting a new battery for it

[fourbanks]

I have asked a friend of mine from Japan to find out at a local level what this error means and hopefully get my unit fixed

it cant be that bad i would have thought as it was working fine and despite the unit's age has had very little use no more than 12 hours at the most

[fourbanks]

i have found a updated link to my unit

Good news - I have located my box of Aiwas and run through the machines. Most of them do not work, giving Caution! errors or just plain dead. Luckily one AM-F75 seems to work ok despite having a damaged jog dial. I have also found four Aiwa batteries, and have one on charge now. All I can do is charge each battery up fully, and play back prerecorded discs on shuffle repeat, to see how long the batteries last, A few cycles should give me a good idea of each one's capacity. I will let you know if any have a half-decent charge capacity in a few days time.

many thanks jim for your time on this matter. we still need to track down on what this error code means (no adjust) i have sent a email off to sony and hopefully but i have my doubts that they will be able to enlighten me

[fourbanks]

I might be able to get hold of the Aiwa mini disc player/AM-F90 was this modal an upgrade to my am-f80 does anyone know ?




thanks

Yes, I have seen that too on eBay. Sorry to disappoint, but inside it is a Sony R900.

so is that not as good Jim to the 80 in what i have now ?

i'm new to ebay and so far have lost out big time on bidding

the last model i bid on at £40 one hour later got snapped up at £140 so i was way out

[jim.hoggarth]

Fact is, it's not what you are looking for. The F90 is just a Sony R900 with cosmetic differences. Even the remote control is a Sony RM-MC11EL, with the lettering changed on the front.

Incidentally, I had a revelation a couple of days ago regarding the NO ADJ error. I am wondering whether it is equivalent to Sony's NVERR or Error EE messages. In other words, the non-volatile EEPROM has become corrupted, effectively turning your recorder into a box of parts. The solution is to run the internal adjustment routines, but without a service manual or some hints as to how to enter service mode, there's no way of fixing this. I am very busy at present, but hopefully I will have time to pull out all the Aiwa machines and check this out.

Jim

Thanks Jim




the service manuals Jim are here there are quite a few ?
