I am now using rechargeable alkaline batteries. They do not have the same problem of leaking charge as NiMH batteries

The "Sanyo eneloop" is a rechargeable NiMh with fantastic shelf life.

Have found this to be a problem with the 2 interchangeable sets I use.
You pop the "new set" in thinking allis well only to find they have self discharged since you last boosted them (say 6 weeks ago)
I tracked it down to one 2000 ma hr battery in particular which I threw out this morning. Thought it was just bad luck -- but perhaps not?

I have been using about 12 sets of NiMH AA - lately 2700mAh Sanyo - conventional NiMH technology.

I endeavour to recharge the full set the day before a shoot, but even there, they tend to lose a lot of their charge even after one day (probably 20% but I've not had time to do the full scientific test).

I am in the process of moving to Sanyo Eneloop NiMH which, though smaller capacity ~2000mAH hold their charge much better and much longer. They use a "super-lattice alloy" to reduce the decomposition of the materials which causes the self-discharge.

The only outstanding issue is how long they will last - my NiMH tend to last only about 6 months although they get serious use including really hot conditions.

I buy my batteries from: Sanyo Eneloop will do phone orders and who have the tools to check the condition of any battery.

Why are you concerned about rechargeable batteries having a shelf-life of 6 months or a year? If you only used them that often you might as well use conventional batteries? I've got a Varta 15 minute charger which works a treat even on 12 volt so there really isn't an issue with 'shelf-life'', I recharge my batteries; that's the purpose of them :-)))
