How strange! Entirely different to mine which charges all the time it is plugged in whether connected or not. It even charges when the computer has shut down as long as the mains is still connnected to the tower.

I expect that your device has Li-ion batteries so I would't worry about any memory effect. Li-ion batteries don't suffer in the say (EDIT - same) way as Ni-Cd batteries did when short-cycled but they still die eventually. Perhaps yours just got old.

I also wouldn't worry about overcharging. A lot of Li-ion batteries have a microprocessor inside them that monitors charge state (that's how the PDA can tell you how much % charge is left when you change batteries) and most PDAs have a reasonably sophisticated charger that monitors battery state of charge and battery temperature and adjusts the charging rate accordingly.

If your battery has more than two contacts (the one on my Axim has five!) you can be reasonably sure that your PDA has good battery charge management that you probably can't improve on.
