The Compass uses a similar battery, listed as TL-2150, which is a 3.6V
lithium cell (labeled "SIZE 1/2 AA"). I can't see the specs of the
1520's battery without removing it, but does anyone know if such
batteries are still made?

I suspect that the connector on the inside end of the AC adapter joins
with the external 16VDC connector via a cable, so that AC power can be
used with a battery installed in the unit, allowing recharge.
Maybe.

Actually, it turns out these are SIPPs. Never had a machine with SIPPs
before. Didn't know what they were.
Yes, I am talking to myself.
