If you've driven your GTA02 battery into cut-off (no voltage between
the terminals), then you can also jump-start the battery by supplying
a bit of energy from an external source, e.g., a battery pack at ~4 V
through a 1 kOhm resistor should do.
When the protection circuit inside the battery detects the external
power, it exits cut-off mode. This results in a non-zero voltage
(3.something volt) appearing between the battery terminals.
When the battery comes out of cut-off, you can draw a bit of power
before it enters cut-off again. So you should be able to boot and
proceed with the normal charging process.
