Self-discharge has nothing to do with the currents drawn by
devices, whether they're very small currents or not. The amount
drawn by devices that are powered off varies tremendously, and if
large enough can damage any rechargeable battery after several
months if care isn't taken. This has virtually nothing to do with
their self-discharge rates. |

Li ion battery packs usually draw some current from the cells even
when not in the device, because of the protection circuit.
I can tell you for sure from having just a few days ago used my
camcorder for the first time in about a year, that lithium ion packs
self-discharge. I have three packs for my camcorder, all of them were
fully charged when I last used the thing, all of them were dead when I
tried them a few days ago (I recharged them). Worse, the
microprocessor in the large pack (Sony NP-F960) somehow didn't realize
that the pack itself was discharged, so it thought there were 1200+
minutes of runtime left and when I got through recharging it thought
2000+ minutes. |

Good idea, but fortunately the date's printed on them.

Yes, I've thought about getting some for my K100D. But they're not
recommended by Pentax because of the slightly higher voltages. Some
people are using them fine though; I think it depends upon the exact
voltages, which can vary from manufacturer to manufacturer.
Still, most AA camera won't physically take those batteries... probably
to discourage people from using them for the same reason Pentax do.

Proprietary batteries are a curse even if they often have advantages. I
suppose phones are even more "volume sensitive" than all but the
smallest cameras though, and I suppose squeezing a battery in must be
tricky at times.
I seem to buy a new phone about once every five years, so I took the
precaution of buying a spare straight away this time. It will no doubt
get lost before I need it.

Hello, Just D:
That's hardly a revelation. <g> Sony is widely known to be the
industry's top provider of "small" sensors (i.e., the type used in P&S
digicams), and also some of the larger ones, contained in DSLR's.
However, even Sony doesn't make the whole cameras, either for itself or
other companies. That gritty job is mainly handled by a certain number
of OEM firms, such as Sanyo and Flextronics, among others.
Cordially,

Hello, Paul:
It's a fact of modern life, alas. The world's industrial base has been
constantly shifting, and not only away from the United States and
Europe.
Even Japan has felt the dour effects of rising labor costs, and like
the Western nations, has moved much of its manufacturing muscle to
Southeast Asia, China, and the Pacific Rim.

Well, I own six Kodak digicams, and they're all made in either Japan, or
China. The build quality is the same (i.e., quite high), in each case,
pun intended.

Then, don't think that. <g>

No problem!
