It seems highly likely to be a fuse. If you think it is in some way limiting the current to the load, temporarily bypass it (short it out).

You say you feel the cells themselves are in good condition / of good capacity but how exactly are you measuring that property?

Try powering a realistic load, such as a lamp bulb of appropriate wattage and voltage or a high power low value resistor, and see if the voltage output from the cell(s) holds up then. Measuring the cell voltages off-load isn't really an adequate check.
