| Will the 60CSx use NiMH rechargeable batteries?
(it's kind of late to ask now, it arrives tomorrow. I just sort of
assumed that it could use them. But apparently it's worth asking anyhow.)
thanks

Yes, it works very well with them.
If it is similar to its predecessor, then there is a system
setting for the type of battery, so the battery meter works
better. Set that to the matching type.
And a recommendation on the sidelines: use Sanyo eneloop
accumulators. They are a technical miracle---NiMH cells without
noticeable self-discharge.
The jury is still out regarding their longevity, but so far they
are working extremely well.

I can whole heartedly rec these batteries. Been using them for about a
year and they are terrific. Might be a little hard to find. Got my
first set at Amazon.com and others at Circuit City.

Try Thomas Distributing at http://www.thomas-distributing.com/index.htm Its
where I got mine. Excellent place.

I am a professional photographer so I do have lot of NiMH batteries
(30-40+ of them), and I think I am gonna place them with Eneloop or Hypid
batteries.
Lets me count the number of battery really in use (just for photography
stuff).
- (2) flashes each uses 4 batteries (8 total)
- (2) battery packs each uses 8 batteries (16 total)
- (2) portable drives for backup, one uses 4- batteries (4 total)
- (2) Wireless receivers each uses 1 battery (3 total)
And dozen spares. Hmmm I think I have 50+ of them <bg>.

I just checked with thomas and the price + S/H doesn't end up good enough
comparing to Amazon free S/H for $25 or more.
I dunno whata do with around 50 of the current regular NiMH so I cancled
the (2) 8-pack AA batteries. But I can't stop myself from researching, and
ended up with (8) AA Kodak 2100 mAh Pre-Charged ($7.88 a pop) and (4) AAA
Rayovac Hybrid 800 mAh ($9.18 a pop). I read they are similar to Sanyo
Eneloop, also the GE/Sanyo eneloop is little cheaper than Sayno eneloop.

I would recomment to keep using them while observing carefully
their health. If any one of them starts self-discharging too
rapidly, discard it.
What I do is charge them, then let them sit on the shelf for a
month, then measure them. Any one that is empty after one month
is discarded.

I am not going to throw them away (yet), but hating to re-charge all of
them before shooting, and most of the time I never need the spare ones. I
was about to buy a better charger La Crosse which has option to re-fresh the
memory, but the problem that it comes with (4) AA and (4) AAA of regular
NiMH batteries that I want to get rid of. And they don't have charger only.

Most of mine are new 2500 NiMH that I just replaced less than a year ago.

I just started using NiMH AA's this summer but don't use them in
anywhere near the quantity that you do. I have 8 cells and use them in
two handheld GPS receivers and in a mobile battery pack recharger for
recharging a mp3 player.
When I got them I got interested in the charge rates and stuff and
quickly realized that the most of chargers that are on the market are
not very smart. And some are actually pretty stupid. So I bought a
Maha MH-C9000 charger and that seems to be working well for me.
http://www.mahaenergy.com/store/vie...p?idProduct=423
Being able to select the charge rates and several different modes of
operation gives me the impression that I've got some pretty good options
for keeping the cells going for some time and for recovering them from
some of the conditions that would otherwise be "fatal" or near fatal.
I've not used the Refresh and Cycle modes yet but will when and if I
start seeing some deterioration in the performance.
I've cycled my 8 cells a total of three or four times now and have not
found any of them to be at low charge states or have short lives when I
put them into use. Some of them had been off the charger for several
weeks or more before I used them and I was still getting good service
cycles.
The rate of use will be quite a bit slower during the winter so I'll
rotate the batteries through every 6-8 weeks and refresh them. It will
be interesting to see if they are still working as well next spring.
I'm using a mix of batteries, from 2100 to 2800 mAH and use a slow (C.4)
charge rate.
I decided to make a commitment to stop using disposable alkalines
because it seems to be good thing to do for the world. But it you want
to do something like that it simply does not make sense to not use a
good battery charger for recharging. The consumer grade chargers that
come packaged with some cells are mysterious at best and in some cases
can be a poor choice because they charge the batteries too fast and have
no capability for attempting the recovery of cells.

Speaking of rechargeables, I have a number of rechargeable AA batteries
of different brands and both Ni-Mh and Ni-Cds. I use them for a lot of
the things that take the AA batteries, like my cordless mouse, digital
camera, flashlights, and those push lens portable lights, etc. Most are
rated at 1.2 volts, but I have 4 Ni-Mh batteries with the name 'Quest',
from Harding Energy Inc. Made in France. Although rated at 1.2 volts,
after recharging, these batteries constantly read ~1.34 volts rather
than the ~1.1, 1.2 volts of the Sonys, Energizers, and others.

Joel,
an "option to refresh the memory" is fishy. 90% of the "memory
effect" is an urban myth anyway, and something like this
function is most likely useless.
Buy a good quick charger instead.
>Most of mine are new 2500 NiMH that I just replaced less than a year ago.
I've used some Sanyo 2,500 mAh cells and found that they work
well for a short time, then start to self-discharge very
rapidly. Longevity is not their strength.
And I was used to the best cells coming from Sanyo, but
apparently Sanyo doesn't make only good products. I hope their
"eneloop" cells live longer. So far they work very well.

Jack,
very true. The worst of all chargers are time-controlled "quick"
chargers. They are essentially cell killers.
The new quick chargers seem to be good. A real quick charger
cannot afford to make mistakes.
For some purposes I use very slow chargers without any control
circuitry. Those are totally idiot-proof and work under
conditions of unreliable voltage, etc.

I am using NiMH batteries mostly for my digital cameras (photography
equipments) and have been using NiMH for more/less a decade now. I don't
remember how much charge those first batteries had (300-500 mAh? but it cost
around $15-20 each)

I have read lot of good talks about the La Crosse and the Maha MH-C9000
(each has some strong/weak points but they are both good), but I started
with 4-5 regular chargers, then (2) 15-mins chargers because quite often I
don't have time to slow-charge 30-50 batteries.

Since it reports the status so you know how good/bad the battery is, and
that's the only reason why I like to get the La Crosse (or MH-C900)

As we have been talking about the difference between regular NiMH and
"Eneloop", "Pre-Charged", "HyBrid" those will keep the charge much longer
(they cliam 4X longer) than regular NiMH battery. And as I mention
Wal-Marts carries (4) "Kodak" pre-charged = $7.xx and (4) "Rayovac" HyBrid =
$9.xx

See other message I reponsed to Jack. I am not having one but 2 quick
chargers to keep up with the need, and cigarette adapter on the run too <bg>

I can't find Sanyo Eneloop locally so I have to settle for Kodak
pre-charged and Rayovac Hybrid.
