That price range is off!

Like I previously stated, I get AA Lithiums (Energizer e2) at Sears for ~$10.00 ($9.99) for
4 x AA batteries that's $2.50/battery not $5.00/battery.

Yes, I suspected as much. So ignore that!

Costco has the Energizer e2 Lithium 4-pak for $6.99 on
the website, I'm not sure about the stores, though. Which
brand are you using?

WRONG!
Lithium batteries are capable of delivering very high currents. If a
flashlight is designed for carbon/zinc or alkaline batteries, the
designers are probably counting on the internal resistance of the
batteries to limit the current through the bulb. Lithiums could easily
burn out the bulb. But, it's your flashlight, try it out. Then tell

us
how it affects bulb life.


I am sorry to disagree with you, but the internal resistance of the bulb

is
what limits the current, (Ohm's law) and not the capability of the

battery.
A 12 volt light bulb will operate the same with a lead-acid truck battery
that is capable of delivering 200 amperes, and not burn out one second
sooner that it would if operating on eight 1-1/2 volt AA flashlight
batteries. Now, having said that, it is certainly true that there are

types
of batteries that differ in voltage output by slight amounts. Lithiums, I
believe, put out 1.55 volts per cell, and not 1.5 as do alkalines. Also,

the
Ni-mhd type might put out only 1.2 volts per cell, so a bulb that is
nominally rated for 1.5 volts would last longer (because it burns cooler)

on
a set of Ni-mhd batteries than it would on the same set of lithiums. But

it
isn't the fault of the battery type, but rather the total voltage that is
impressed on the bulb filament. 12 volt lead acid batteries, for example,
can be charged up to around 14 volts, so one should be careful when one

uses
them in devices that are meant for a nominal 12 volts, not because of

their
internal resistance, but simply because 14 volts might smoke the
device.........




Utter ****ing ********, you know **** all.

We were advised here by Panasonic not to use Alkaline batteries in remote
controls, due to the lower battery resistance..

If you short out a battery, (effectively an infinite load) then the current
will be limited only by the internal resistance of the battery. But, for all
reasonable loads, it is the load resistance that is the determining factor.
A remote control should draw very little current, so I respectfully suggest
that Panasonic was wrong........

If Minolta tell me don't use lithium in a device, I will heed
their advice. It's too expensive not to.

The only thing internal battery resistance would affect is the short circuit
current. If the battery load is reasonable, (so the batteries would last
more than a few minutes) then this internal resistance can have no
deleterious effect on the device. I suggest that the reason the manufacturer
doesn't want you to use lithium batteries is because they put out a little
more voltage per cell than alkalines, so a set of them might over voltage
the device. If you believe the specs on the device are that marginal, then
by all means, use the batteries the manufacturer recommends. As for me, the
determining factor is the batteries tendency to leak in time and destroy the
battery compartment, especially in devices such as flash units that I may
not use for a long time. This has happened to me often enough so that I
usually just remove the batteries altogether after I use the device. If I do
this with some cameras, however, the camera looses its internal memory, and
forgets what frame it's on, and other important information, so I keep it
energized with a fresh set of batteries every few months. (I usually am
using it every day or so, anyway)

This is true, but the internal resistance of the battery is only a very
small percentage of the resistance of the load, with the exception of a car
battery during the "start" operation, where the battery is very heavily
loaded. This is why a car battery's output drops to nearly 8 volts while the
starter is turning over the engine. Normally, the load puts so little load
on the battery that the voltage difference is unmeasureable.
There is one thing that I forgot to mention, however. Sometimes the
manufacturer specifies a certain type battery because of charging
considerations. Naturally, if the batteries can be charged while inside the
camera or other device, and the manufacturer supplies the charger, then only
the specific battery that the manufacturer recommends should be used. -
Worst case sceneareo would be if one tried to use non-rechargeable batteries
such as alkelines, and the charger would overheat and explode them while
they wre inside the device, damaging that device. - In this case, I agree
completely. - Only use the manufacturers recommended battery.

It is probably (knowing Sony's battery life history) too high a current draw
on a Lithium battery and they tend to explode when overloaded.

Good points. I found the same lack of quality support with Sony Vaio

laptops. Therefore I
won't buy Sony.

As for using Lithium AA's in the camera. There is absolutely NO reason

why you should not
be able to use them. Electrically they are the same as any other AA

batteries, they just
last longer. I buy mine from Sears at ~$10.00 for 4 x AA batteries

(better price than Radio
Shack).


When the camera manufacturer puts in a warning:
"AA Lithium batteries cannot be used" it is there for a good reason.
