All of you who love AIWA MINIDISC player MODEL AM-F80 AM-F70 etc USES the following battery type: LIB-902 FACT: Battery is EXTINCT. no ones make them anymore. GREAT NEWS: you dont have to go around hunt for used one that likely passed shelf life which does not hold charge and pay 100+ dollars!! SOLUTION : AAA Li-Ion ULTRAFIRE 3.6 VOLT. cost about 3 dollars at Ebay. Does it fit? YES it fits into the battery compartment slides right in. Its DIAMETER is 1 cm which is exact match for OEM LIB902 and it fits into battery compartment. see picture insert. fits right in. Its cylinderical compare to OEM lib902 and shorter so you need to make small coil spring and put it inside of battery chamber to fill the gap! thats it .also I used cutout paper to make the floor elevated a bit before insert battery.(see photo it has cardboard cut out on floor of battery compartment) Note that in the photo you see paper wrap outside of spring to prevent coil spring come into direct contact with battery compartment wall. to make a coil buy a good conducting wire like Copper etc and warp around the small diameter pen(which is less then 1cm in thickness) few times and make the coil then at the end make the small tip to contact with plates. You can use regular 3.6 V Li-ION charger to charge the battery and use it. Works perfect I use it as they work great.. Better and much cheaper then the OEM LIB902 but it has apx same mAH!500 vs 700 mAH JUST BUY few packs say 6 and charge it at once then use it . GOOD LUCK TO YOU . AIWA AM-F70 is one of the best recorders I know, its only the battery that made this recorder unusable or have to use it with bulky external battery case. Many trade in AIWA for this reason but now you dont need to. If you dont have optional external AA battery pack. you can use any other types of external rechargeable battery backups (look for PSP yellow tip plugs) it will fit into the AIWA power plug. Alot of AIWA AC plugs are interchangeable with SONY so look for one if you need it.
