Now I've got some NiMH batteries what is the best way to use them to get optimum life ?

Should I try to cycle them from fully charged state to completely flat.

maybe they be kept fully charged when not in use.

Any tips welcomed.

These battery's are not like NiCad which have to be flattened totally everytime but it is advisable to flatten them occationally.

My Nikon camera instructions advises to flatten completely for the first three charges.

This is limitation for NiMH, but not for Li-Ion which used in modern laptops.

NiMH are self discharging so always charge before use.

I have been using this type of battery for three years, in the most power hungry of cameras,the Minolta D7. during this time I have never discharged the batteries before recharge. I have taken well over 25,000 photos during this time and I am still using my original four sets of batteries. They do not suffer from the memory effect, so don't waste your time discharging them.

The batteries and chargers I use are Ansmann & Maha, maybe a little expensive but well worth the extra.

Shizzy does have a point, It usually takes several cycles for these batteries to become "conditioned" achieve full efficiency

Thanks for all the responses.

The great advantage of Ni-MH batteries, apart from higher capacity, is that they don't have a "memory" in the same way as Ni-Cads and can be "topped up" as necessary.

Even so, as rightly pointed out, it's best to occasionally let them run virtually flat and then fully recharge.
