Hi Andrew,

Thanks for the info. I was under the impression that the 1502's do not
require energy from this battery until the unit is powered up. This being
so, there appears to be no good reason to use a battery at all. As long as
the 1502 has power, either through the AC input or 12 vdc battery, then you
should be able to tap into this 12 volts dc, which is also available when
being powered from 120 vac and use it to drive a low cost, low
power/dropout voltage regulator and be done with it forever.

I've not had an opportunity to work with Campbells new TDR, and having 4
fully operational 1502 systems based around CR10's, probably won't get
around to it for a while. I'm sure it is an excellent product, as I've come
to expect with all of Campbells equipment.

Sincerely,

Steve
