Re-charging Ni-MH14WM(A) battery with MZ-N910 charger...

Hey people! I bought the MZ-N910 NetMD about a week ago and have started recording, editing and listening to my fave tunes with ease thanks to the SonicStage software and the very cool NetMD unit... However, I do have one question for those of you that might know...

It is not really a problem but more of a query. When I charge the battery using the charger provided with the MZ-N910, it usually takes about 3.5 hours for a FULL 100% re-charge which is normal and which is what the manuel says. So no problems there... However, after a full 3.5 hours re-charge when I lift the MD from its cradle and put it back in the cradle again it will start re-charging even though it is full?!?!? This is confusing me as now i am not sure if I am actually getting a full 100% re-charge after the initial 3.5 hours of charging... It re-charges for about 1-1.5 hours after the initial 3.5 hours of full re-charge. Why does it do this? Is it not re-charged fully after 3.5 hours? Is that why the unit can re-charge more after the 3.5 hours of charging?!?!?!?

I also have NC-6WM batteries from my old cassette recorder walkman which was really cool in its day smile.gif, and when I try to re-charge them in its own re-charger after a full re-charge, the recharging stops after 10 mins... So the unit cannot re-charge it anymore because it can see that it is already FULL. This does not seem to happen with the N910 as it can continue to recharge 1-1.5 after a full recharge if i lift it up from the cradle and slot it back in again...

So guys, tell me is there a problem with my NiMH-14WM(A) battery?

Cheers

PS: Just now the unit started re-charging again on its own?!? And this was after a full re-charge of 3.5 hours PLUS 1.5 hours of extra recharge on top of that FULL recharge... What is happening is beyond me! smile.gif Some one help me out here cos I am really curious!

Thanks again!

this is meant to happen since the cradle that came with it doesn't exactly have a function which senses the charge on the battery when the unit is on it...so even if full it will still try and charge the battery for an extra ???hrs...(and also NiMH batteries don't have those funky chipsets in them to determine the est. remain batt life like those infolithium batteries do so it will still keep charging regardless whether or not it's full)...

Ok thanks for the info mate!

Btw does this shorten the life of the battery? I mean the NC-6WM battery that I have stops recharging after only 10 mins if the battery has been fully recharged before but the NH-14WM(A) doesnt and continues to be recharged for 1 hour or more even if it is fully recharged... I thought the nickel hydride batteries were better and "smarter" than nickel cadmium batteries...

Thanks again for the help matey!

they should be better than the NiCd batteries but it still has the memory effect...i think the only batteries that have neglible memory effect would be the Li-Ion/Lithiun Polymer or the upcoming Zinc-Air batteries...but getting back to ur q yes it does shorten the life of the battery so it's better if you charge it directly on the unit rather than on the cradle (i heard that if the battery is fully charged u can't overcharge it when the adaptor's plug-in to the unit no matter how many times you try to push the charge button...not too sure of this since i've never tried it myself...)

Thanks for replies mate!

Btw i dont think there would be any problems using my old NC-6WM batteries with my new N910 would there? I mean they are the same voltage only has half the capacity...

Oh and one last question: I read in these forums that I can upload music through my soundcards LINE IN with a program from Creative. Which program do I have to use? I own a Soundblaster Live! soundcard and I run win98se. I have updated my Creative Playcenter to version 3...

thanks in advance.

Cheers

Actually, Majestic, NiMH batteries have negligible memory effect. At least this is according to Rayovac, who is probably the leader in the area.

Berky... you're right that NiMH batteries aren't as smart as the new LiIon ones, but they're still much better than NiCads.

(I remember when I used to rely heavily on NiCads... they're terrible... they don't get much more life than "Heavy Duty" batteries.)

Well I have started using the NC-6WM batteries (I have 2 of them) on my N910 and they are working great so far (touch wood:)). Although after around 4-5 hours of LP2 playback the battery down to 75%. Which is ok i reckon, cos it is less than half the capacity of the NH-14WM.

Does anyone know if there is a higher capacity battery than the NH-14WM out there? I havent seen it so far...

Cheers
