If the internal battery of the 500 is the same one as the one of the 505, it is best to at least recharge it every 3 months.
When a Li-ion battery reaches a state of being completely depleted and beyond, it might not be able to recharge anymore.
It might also lose a lot of it's capacity. It works opposite from Cd batteries in that Cd batteries NEED to be depleted before recharge.
Li ion batteries lose charge (memory effect,but then for emptying batteries)when they get empty.
Likewise Li ion batteries seem to wear out slightly if you fully charge them, and then let the battery depletes itself over time. It seems best to keep Li ion batteries stored with 2/3rd of charge, and charge them twice to trice a year, depending on the type of battery.
Larger batteries (eg laptop) need less recharging than smaller ones (eg cell phone), for they remain charged for a longer time.
