Or should you leave them on charge all the time?

Don't leave them on charge all the time. Not only will you waste electricity, you will damage the batteries and the charger. If it is an issue, recharge them every couple of months.

This is copied from a website run by my photo specialist, I think the information I get from him is worthwhile, and I hope you do too.
Nickel-Metal Hydride (NiMH) - Rechargeable
These batteries replaced the old Nickel Cadmium (NiCad). These batteries hold much more power than their ancestors, and don't suffer the "memory" effect. Additionally, while NiMH batteries do have a higher entry price than alkaline (about $20 for a 4-6 hour charger and 4AA batteries) they are very affordable because they can be recharged 200-300 times in their useful life. The downside to these batteries is their high self discharge rate, they will be dead after a few months of sitting in a drawer.
Note: NiMH batteries output 1.2v instead of 1.5v, this will not be an issue in most cases where you use 2-4 batteries in a device, however for devices that use more than that you may experience shorter battery life or the device may not work at all.
Ideal Uses: Digital Cameras, CD/MP3 Players, Electronic Games, Toys, and any other device that will use a battery up within a few months.
Not Recommended for: Flashlights, Smoke Detectors, or any device you may need to depend on in an emergency.

NiMH stands for Nickel-Metal Hydride, the materials used in some battery packs. Unlike NiCad batteries, NiMH batteries do not use heavy metals that may have toxic effects. In addition, they can store up to 50% more power than NiCad batteries and do not suffer from memory effects.
They will in time loose thier charge if just sitting.

Yes, they discharge over time. I have a few batteries on hand. If I know in advance that I will be changing batteries (and it's rarely an emergency, is it?), I put one of those batteries in the charger for a bit to "top it off." This usually takes no more that 10 minutes or so.
Do not leave the battery on the charger all the time, though.

From my experience, lithium re-chargeable batteries loose their charge after a few days.
Store bought ones will only start to loose their chage after using them. Fresh batteries will retain their charge.
So if you have something coming up where you need batteries and spares fully charged, I run mine down a day or two before, then give them a slow charge the night before.
With the batteries I have, if you try to re-charge them before they are out of power, they will only charge to the point where they were charged to (ie if they usually last 6 hours and you re-charge them with 2 hours of charge left, those batteries will always only carry a max charge of 2 hrs)

Yes, they do. This link has a good FAQ on NiMH batteries.
