All camera & computer batteries (NiMH & LiION) will always have some 
kind of discharge when not used for a smaller or longer period.

I can tell that I haven't been using my MBP for apprx. 3 months due to 
I've been moving to a new apartment, but the other day I powered it up 
again and the discharge had only been apprx. 15% - i.e. apprx. 85% still 
left in the battery after not being used for nearly 3 months.

Reg. camera batteries - primarely now LiION - it also depends on the 
camera brand and model. - I'm using more brands of cameras - Canon, 
Olympus, Pentax and Sony-Monolta - right from a Canon EOS 5D II 
fullframe to Olympus OM-D E-M5 II with cropfactor 2,0 and Konica-Minolta 
7D and Sony ILCA A68.

Earlier I also had a EOS 450D (Rebel series in the US). This 450D 
discharged the battery within a month if the camera wasn't used - no 
matter whether it was the orig. Canon battery or a Patona. So does the 
Konica-Minolta 7D. Therefore I now always take out the batteries when I 
know that the camera won't be used for a while.

Also I never use 'noname' batteries, but only those I know are using 
either Panasonic or Daimond cells. - Here in Europe the best 3.-party 
batteries are Patona, MTEC, MTB, OTB and BluMaxx. These brands aren't 
the cheapest, but indeed cheaper than orig. batteries. - Fx. where an 
orig. battery will cost round €45-50, the best 3.-party (Patona) costs 
round €15-18. - Some even as low as €12 (MTEC, MTB, OTB). - And I always 
buy batteries with compatible info-chip to be sure that I can use the 
orig. charger.

Because of my move to new place I also haven't been using my EOS 5D II, 
but the day before yesterday I powered it on and found that there still 
was apprx. 70% left in the MTEC battery. - Just to check I also powered 
on the Sony A68, - this one had discharged to only apprx. 15% left - 
also with a MTEC battery. - Now I'd been curious and also powered on the 
Pentax K-3... Within the same apprx. 3 months of not being used it had 
only lost apprx. 5% discharge - also using MTEC batteries.

Cheers, Erik Richard
