DSLR Battery - old Genuine or Hanhel?

[Skink 10]

So heres my quandary - need a second battery for my 10 year old DSLR but dont really have the knowledge of how storage would affect/damage the capacity of the thing

 

I can get an genuine battery from Microglobe but I have no idea how old it is, the camera was discontinued years ago

 

I can also get a similar Hanhel battery from Wex - that battery might be more recent stock, I dont know

 

A third option is cheap aftermarkets are everywhere - but I dont think I want to put one in my precious DSLR

 

The price is about the same with Wex/Microglobe. I like genuine but I trust Wex more than Microglobe . . . So what to do?

What brand is your dSLR?

 

I have a Nikon and have used officials and aftermarket batteries without issue, although I will admit that the aftermarket batteries tend not to last as long.
