    About putting a known load on the battery ... can you do this while
    the product that is running from the battery is still working?

    regards,
    SW.

This is exactly what we do to determine a 6 cell NiCd pack's state. I
discharge it over a 47E resistor for 10s and measure the voltage under
load.

A few people have asked about good batteries to use lately. A very nice
battery (but a bit expensive) is the Hawker (previously Gates) Cyclon
2V lead acid cells. They combine all the nice features of lead acids
and NiCds.

I would think so - you are not shorting it out, but getting a reasonable
current (few mA, normally) so you are loading the battery
