What the battery requirements for all these bluetooth devices.

Thx, {|;-)

My HP TC1100 with BT runs a bit over 3 hours in the cockpit on its internal
battery, so I don't even have to hook it up for shorter trips. (YMMV, as I
found that the APIC software was so CPU intensive that I only got 2 hours.)

My Bluetooth GPS is a Holux 230, which claims 9 hours of battery life. In the
couple of months I have had it, with charging before a flight, it has never run
flat. That said, if I had it to do over again I would get the Holux 231 with
has a removable cell phone type battery. Then I would carry a charged spare and
absolutely never worry about having to plug the GPS receiver in. (I do carry
the 12v power cord for the Holux, however, just in case.)

Another thing: I made it a priority to get a GPS with an external antenna jack,
assuming that using a good antenna would be worthwhile. Not so, the Holux
internal antenna works as well as when I plug in a Garmin antenna. So ... one
less wire, one less gadget needed. I made a suction cup bracket to put the
Holux on the windshield & I just stick it there with no wires connected. Works
fine.
