I remember the days when MD players/recorders had awesome battery life, where'd that go?

it went together with the limitation of 80 minutes decently sounding audio on one disc...

:lol: isn't there a "minidisc users are moaners thread"? well, this thread should be linked :P we've got 90 min CD-SQ, 8 HOURS of HiSP on one disc, uploadable recordings and now even uploading of legacy stuff,... but hey ... the battery life could be better, don't you agree? :lol:

PS: sorry, these Monday mornings do make a (bigger) cynic out of me

According to my feeble understanding of battery technology, the limits are established by chemistry and size--there's only so much juice available from a given form factor and chemical mix. The engineers are always tweaking away at it, but a gumstick is going to hit a capacity ceiling. That's why so much effort goes into minimizing a unit's demands on the power source--why, for example, it takes so long for my single-AA MZ-B100 to do a data save, or why backlit displays have auto-turnoff. The easy answer (from an engieering point of view) is to build a device big enough to house more batteries, but the designers are apparently aiming at minimizing size.

Is it possible to rig up a alternative power supply using ordinary batteries for this unit or do people just take spare sticks with them into the field?

I bought two spare batteries off eBay from two different merchants, both from China, and have had no problem whatsoever. Total cost $30 for both.

There has been some question on this forum as to the origin of said batteries, whether or not they are genuine Sony or not. All I can say is that they work, and that I've found them to be as good as the original.

I also got some cool stamps from China. :D

I second that.
