pauljones52 Posted January 16, 2006 Report Share Posted January 16, 2006 Welcome, almost all minidisc players can use an external AA battery with a supplied add on case. The exceptions are DH10P and NH1 (I belive). the NH600D takes an AA battery in a slot built directly into the unit itself. All units except the NH600D can take removeable gumstick shaped batteries which can be recharged in the unit itself. Uploading times are pretty slow for PCM recorded files, compressed ATRAC files are slightly faster. A four min PCM recorded track would take ~1-2mins to upload in my experience.Have a look at http://www.minidisc.org/part_Hi-MD_Sony.html for furthur information on the units, hope this has been helpful!Matt Quote Link to comment Share on other sites More sharing options...
The Low Volta Posted January 16, 2006 Report Share Posted January 16, 2006 NH700 & NH800 also take an AA internally, no add-on Quote Link to comment Share on other sites More sharing options...

burns3016 Posted January 27, 2006 Report Share Posted January 27, 2006 (edited) Apart from aesthetics, why don't all MD-Units just use AA's ?They are cheaper, easier to obtain & generally speaking, last longer, than gumstick-batteries.Please enlighten me !

atrain Posted January 27, 2006 Report Share Posted January 27, 2006 they can't conform to the form-factor requirements of ultra small/slim player only units Quote Link to comment Share on other sites More sharing options...
pauljones52 Posted January 27, 2006 Report Share Posted January 27, 2006 (edited) Using gumstick batteries means the players can have a recharge unit built into them. Would be hard to do for AA's due to different capacities/chemistry's, non rechargeables etc. Plus sony get the money when you buy a new battery, add on sales!

If i find a cheap one I might consider buying it! Do you know what the battery life is like? I've seen AA's with 2900mAh capacity which would be amazing!

tekdroid Posted January 27, 2006 Report Share Posted January 27, 2006 Using gumstick batteries means the players can have a recharge unit built into them. Would be hard to do for AA's due to different capacities/chemistry's, non rechargeables etc. Actually it's not hard at all, which is why Sony units like the MZ-NH700 let you charge the AA that comes with it. All that's needed is some 'smart' charge logic built into the units.That said, I haven't tried to charge 2500mAh batteries in the unit, only their supplied 700mAh one. It would probably work but take some time, depending on the logic they have in the units; whether or not it is built like the more advanced 'smart' chargers charging the batteries fully and monitoring voltage, temp, battery type, etc. Quote Link to comment Share on other sites More sharing options...
A440 Posted January 27, 2006 Report Share Posted January 27, 2006 http://www.minidisc-canada.com and http://www.minidisco.com have NH700 for under $150. Quote Link to comment Share on other sites More sharing options...

Do you know what the battery life is like? I've seen AA's with 2900mAh capacity which would be amazing!Hi Matt J !The supplied battery does not last very long at all (very bad actually). According to the specs. about 7hrs at Hi-SP & 9hrs at LP2 (I use both theses bitrates) - but this is not what I have seen in reality. I would say about 1/2 - 2/3 of the stated life. here is a link to the specs.(including the rechargeable battery life) http://www.minidisc.org/part_Sony_MZ-NHF800.htmlBut, all is not lost ! In the bundle-pack I purchased from MiniDisc Australia, I received a Sony Fast Charger with four 2300mah AA rechargeables. I only use these. Why bother with the crapping 700mah. However, I did use it initially, so I could try the recharge capability of the MD-Unit itself. It takes about 2hrs to charge the supplied 700mah AA. The fast charger charges one AA-2300mah in 1hr OR four AA-2300mah in 4hr - not bad ! But, I would not consider trying to charge the higher capacity AA's in the player itself, as I don't really need to anyway.So, why don't all MD-Units use just the good old AA-rechargeables - better price, power & availabiltiy ? It must be about the looks (ie. the slimmer machines use the gumsticks).Any thoughts ? Quote Link to comment Share on other sites More sharing options...
