Battery won't fully charge

[Cert]

I've had my NZ for almost couple years now and it's been working flawlessly even though I've dropped it couple times which resulted in a loose hinge but it works great nonetheless. Just couple days ago, I've noticed I can't get a full 100% charge no matter how long I keep the unit on the cradle. I'd get a 100% for about 3-4 seconds and it immediately drops down to 48%. I've tried searching this issue but nothing is coming up. Please advice.

"couple of years"? Wow, with one and the same battery?

I guess it is time for a new one, this one seems like it is dying... :(

BTW: what does your charging cycles and degradation say?


cheers Nicolas

Charge cycles: 263
Degradation: 4%

YES, this is what I posted last week in another thread.

Me Too!! my nz has worked flawlessly for 2 years, now all of a sudden the battery drains very quick.

I have 267 cycles with 2% degradation!!!???
This issue first began when I was at 260 cycles...

Is this a battery issue? That's my only guess at this point??? Anyone know where the best place to get the cheapest battery is? -A new battery?

[eric2002]

I assumed because I was only at 2% degradation that I'd get another 98% out of my battery...guess not?

Also, it's weird that Cert and I have nearly identical charge cycles, yet our degradation is different.

Someone suggested I try resetting my clie while it's in the charger, however that hasn't seemed to help.

I've been pricing new batteries ever since I posted and I'm plesantly surprise to know they are only about $20 on ebay.

[eric2002]

Yes I just found a new battery for: $49 http://store.l-f-l.com/cgi-bin/cp-app.cgi?pg=prod&ref=PEGA-BP500

are the ebay batteries new?

This makes me very happy, I assumed they were $100 because that is what Sony was asking for them on their site. funny we both had the same issue at the same time!

[eric2002]

yes, your right, the ebay deals are much better.
Also that link I posted shows a battery that is only 1000mah, our NZ's use a 1200 mah.

[Cert]

Yes, they are oem sony batteries (at least that what it looks like). I'm assuming they're cheap b/c nzs are discontinued. Here's the link to ebay:

thanks, i just purchased one, $17 + shipping, $22 total. It's coming from Hong Kong (I live in San Francisco area).

I am so happy that it's only $22. My NZ has become almost unusable, going from a near full charge to 10% in about 40 minutes -just using the calculater and memo apps.

What do these terms mean mean?
Charge cycles: 263
Degradation: 4%
I am losing my battery. I look at it and it looks like its fully charged but then in a few minutes it drains a lot.

[eric2002]

yep, your probably having the same problem as Cert and I. We are both at 260+ cycles and having serious battery issues. My guess is that the battery is just going bad.

The good news, as Cert pointed out, is that you can find a new battery on ebay for as little as $17-25.

I am guessing that the batteries in our NZ's are good for about 2 years?

Charge cycles:
Degradation:

More cycles is better or what?
How do You interpret degradation?

[eric2002]

"charge cycles" represents the amount of times your Clie has been charged. I believe your Clie has to go below a certain level before it registers a new charge cycle. Topping off your Clie won't add another charge cycle.

example: if you have "262" charge cycles, this means you've charged your Clie 262 times (from a certain level like 50% or something to a full charge).

"Degradation" represents the amount of use of your Clie's battery. I am not sure how accurate it is, as I have 268 charge cycles and only 2% degradation. Whereas others have 260+ charge cycles and have 4% degradation?? I am not sure why there is a discrepancy. Also, one would think that 2% or 4% degradation is very little, however my battery seems to be at the end of it's life, but I only show 2% degradation.

hope this helps.
