First of all, the GTA02 doesn't have great power management, also due
to a number of hardware bugs. So a efficient stand-alone tracker will
certainly do much better.
However, without display and so on it can be doable - but not by any
standard battery that fits in the case.

Cheapest way is probably a standard 4.5V alkaline battery at 6 Ah,
should be enough for just about 3 weeks, doesn't even need any
additional electronics for a quick'n'dirty solution.
