Question on Good Battery Tester for AA and Other Consumer Ba

[esb100]

My digital point and shoot camera gets an extremely limited number of
shots with my AA 2500 mAH rechargeable batteries. I've tried alkalines,
which don't do too well. Energizer Lithium did better, but I still get
nowhere near the thousands of shots Pop Photo gets with the lithiums in
its tests.

I've read that some digital cameras are designed or manufactured with a
flaw in which anything more than the slightest drain of the battery
causes the batteries' voltage to fall below the level needed for the
camera to function.


Before I am convinced that this is my problem, I thought I should see
if the batteries are getting a full charge. The only tester I have is
the old Radio Shack red-yellow-green range $5 model, which does okay,
but I'd like one which digitally shows the voltage and mAH reading for
the batteries so I can know how good a charge they are getting and how
well they maintain their power. I would also like to be able to test
123 and CR2 batteries. Can anyone recommend a good model? Thanks

You didn't say if the camera is new.

If it is, perhaps it is defective.
If the batteries are old, maybe they're at the end of their lives.

I would hope not **designed**, but now we're on the same page.

Testers aren't much good on rechargeables.
