Hi,

I just noticed that SHUK now offers both, the external battery pack AND original replacement for the internal battery.

The external pack is labelled 1800mAh, which is roughly 3x the internal capacity. To me it looks like two 1865 cells in a row, i.e. about the length of the NEXTO. Price: 39.90 Euro.

The internal replacement battery is 26.90 Euro.

Those prices are really customer-friendly, not like the usual ripoff like the camera batteries.

On an unrelated note, can you run the SD-CF tests, this time with a generic multi-format to CF adapter (well, stuff like SD/MS/MMC to CF)?

I'd like to know how that fares compared to the disappointing performance from the Minolta's SD-CF adapter.

SGS already told me, that they were shipped to SavitMicro (who
delivers shuk).

Far too expensive in my eyes, just take whatever (camera) battery
you like with two lithium cells and put the right plug at it (or an AA cell
holder for 6 or 8 batteries - use a diode in row here so that they can't
be charged and there is no danger when batteries are put in in wrong
direction).

Well, probably this one is not so easy to find...
 
Does anyone know and/or has anyone tested to see if the Nexto will run with a external power source, but without the internal battery in place?

I'm interested to know in case the internal battery should ever fail while I'm on a trip. I'd like to know how to solve such a problem. I had been thinking that maybe it would be worth having a second battery that is identical to the internal battery, to use as a spare if the Nexto requires a functional internal battery. My plan would be to build a container that would hold a duplicate pack that could be used as a external power pack, but also could be taken apart to use the duplicate LiPo pack in the Nexto in an emergency. If the Nexto does not require a functioning internal pack to operate, then I would not be concerned about having a duplicate pack handy, but if it does need a working one in the Nexto, I think it would be nice to have one on hand for emergency.

Yes, it can be powered by everything without the need of the
internal battery (Firirewire, DC adapter, car adapter, external battery...).

That's not such a good idea. It only gets older too and you finally only
have to non working.
 
OK, thanks for the info...

Since it works without a internal battery, my concerns and/or need for a spare are not valid...

Your idea of using a holder for my Camera's spare battery is a good one... Now I just need to find a good holder for a Canon BP-511 style battery...

Do you mean that having a spare internal battery, and keeping it (unused) in case the original one fails, is not a good idea? Will it "get old" and fail even if never charged?

I've been trying to find some information about the life span of a LiPo cell and haven't found much yet.

I did find somewhere that a LithION battery will only last 2 or 3 years even if just sitting around unused.

Now I've got LithION batteries that are at least 3 years old and are still working, so I'm not sure how much I trust what I've just read...

I've found nothing even close to definitive on LiPoly cells... Yet I have no reason to beleive that you can't get at least 3 years...

I think what d70_europe was saying is that there simply is no reason to keep a LiPo cell sitting around as a spare and it certianly wouldn't last forever even unused...

For me, the bottom line is that as long as the Nexto will operate if I removed the internal battery (if it fails) and I connect a external power source... then there really is no reason to keep a extra battery lying around unused... (perticularly one that's just 650mAh).

All batterys have a limited total life span, wether they are used or not.

Yes. It makes no sense if you buy a spare one now and till you really
need it (probably in about two years) it's almost gone too.
All lithium batteries are getting older no matter if they are used or not
from the day on they were made.
It is said the best way to store them is with 40% charge at
temperatures like in the refrigerator. My lithium batteries are always in
the refrigerator if I don't need them. Just do a search at Google or
whatever you pefer for "prolong battery". Here is one article about it:
http://www.batteryuniversity.com/parttwo-34.htm

And for the camera battery holder: I have a quite cheap one which is
sold separately for an universal lithium battery charger. Put a plug at it
and you have a emergency battery for the Nexto - or use the Nexto
and charge your camera battery with it without the need of an
additional charger to take with you.

Here is the charger for which I got adapters separately:

http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=50512&item=7524147537&rd=1

The complete set is rather expensive, in the U.S. you can get a
complete set of a different one for only a few dollars and it should be
the same (just search for "BP-511 charger" at Ebay).
This charger has one advantage others might not have: the AC/DC
adapter has the same output like it is needed for the Nexto. At least
the adapter that came with my Nexto is too big for my taste. The one
from the charger is really extremely tiny here, I have never seen a
smaller one - especially with this power (however unfortunately
only for 230V AC). You have to replace the plug to a smaller one so
for the Nexto...

Which holder is it? I have the Olympus BCM-2 Li-Ion battery charger for the Olympus E-1: AC 100V-240V, 12VA (100V) 16VA (240V), DC 8.35V 400mA. Would that do for the Nexto? And which plug would I need?

Sorry, my questions are basic I guess, but I know really nothing about all this ;-)

Bernard
 
The battery holder d70 is speaking of is simply part of a battery charger... there are many brands and often you can find what they refer to as a 'universal' charger which has a holder that will accpet a wide variety of batteries... All you need to do is find holder/charger that will hold your BCM-2 battery...

These charger/holders typicaly are powered by some external power source that is generaly right around 12 volts, they often come with a AC to DC transformer and also a ciggerette lighter adapter. The external power source plugs into the battery holder, via a small round 1/8" or 1/4" jack...

What D70 has done is taken the holder from on of these chargers, and made a small cable that plugs into the Nexto's external battery socket on one end and then plugs into the battery holder on the other end. This allows the use of the camera battery as a emergency backup power source for the Nexto...

It just so happens that you can also use the Nexto to charge the battery that is connected in this fashion as well, by simply connecting any suitable power source to the other connectors such as DC IN on the Nexto, etc...

I have a universal charger made by AMBICO, you can find simmilar chargers at Best Buy, Walmart, KMart, etc... nearly anywhere. You can find the components to make the short adapter cable at Radio shack, or by caniablizing some old transformers that you may already own.

Does that make any sense?

OK, I understand what your doing... I could do that easy enough.

I was hoping to find a battery holder that was very slim and/or not much bigger then the battery itself, so I could make a nice sleek looking thing. :)

In fact the adapter/holder itself is not much larger than the battery.
You can get rid of some "balast" which is needed for the former
charger (contacts, the bottom plastic part...) and just solder a cable to
the battery contacts. This way only the battery contacts and the
plastic holding the battery is left over.

No - the Nexto needs about 12V, at least for charging - and more
current/power. The Nexto AC/DC adapter has 12V and 1.2A.

Yep! Here is the charger I have (for my Olympus E-1), with a battery next to it:



It is tiny, and has no AC/DC adapter. I guess if I could find a cable connecting the charger (the flat double plug visible on the pic above) with the small, round plug of the Nexto I could use this combo both for charging my camera battery and as an external battery for the Nexto.

Provided... the voltage/whatever is OK. I guess the important point is the battery characteristics, not those of the charger? Anyway:
Charger -> output: 8.35V, 400mA
Battery: 7.2V 1500 mAh

OK for the Nexto ? ;-)

Wire a couple of these together with the correct connector, shrink
wrap and were ready to go... 2000mAHs

They list the voltage as 3.6v, but aren't they really 3.7v? and
would it hurt if they were only 3.6v?
Click to expand...
No, we already discussed that earlier. Charging only is a bit less.

This are the usual 18650 size lithium batteries (like in the original one) -
and rather cheap. But I would NOT use naked single cells, you won't
have protecting circuits this way!
Nevertheless it would be interesting what protecting chip there is
used for the original battery (TI has some, I used them for the
batteries I made for my Nixvue Vista).
