How often should the rechargeable batteries be changed out?

[jamahn]

I know how often I need to replace my Arlo camera non-rechargeable batteries. My past experience with rechargeable batteries is that they don't have the same capacity as non-rechargeable batteries and therefore don't last as long. I don't want to be frequently changing out rechargeable batteries. Does anyone have relevant experience with the rechargeable batteries and can give me an estimate of how often they need to be changed out?

The rechargeable 123 cells have only half the capacity of non-rechargeable.

The most capacity you will get is about 750mahr.  ( if they say anything more it's false as you can only physically fit that much chems in that size package )

Use the li-ion 3.7v cells and they will last half the time of the OEM.  But, it is a big money savings.
