The charger is basically just a simple transformer connected directly
to the batteries via a resistor and a diode. The led just indicates that
the battery is plugged in and connected to the transformer.

I'm actually in the middle of rebuilding my T45 battery pack. I'm using
20 standard 700mAh AA cells to replace the ones that were originally in
the pack. The pack consists of 5 groups of 4 AA cells. The charger says
it delivers 5.6V at 470mA so that works out to 94mA per group. It should
then take about 7.5 hours (700/94) to fully charge a discharged pack.
This corresponds roughly to the 8 hours that Olympus recommends. For a
good discussion on charging NiCad's, take a look a the following URL:
