So I have tried the “off-brand” or “no-brand” batteries from eBay or similar places on the internet simply because they are a fraction of the cost.  To start, these batteries do work.  They power the camera and will generally get you through in a pinch.  However, in my experience, they drain much quicker than the original Sony batteries.  Then after some time they no longer recharge to 100% capacity.  It took about a year for my generic batteries to no longer fully recharge.  Compare that to the original Sony battery that came with the camera several years ago that still performs as new.

Since I shoot with a Sony I am only speaking specifically about the Sony NP-FM500H InfoLithium Rechargeable Lithium-Ion Battery that my camera uses.  But the good boy scout rule applies to whatever camera you shoot with and I’d be pretty confident in saying original manufacture parts, in the case of batteries are a safe bet for any camera brand.
