Disposable batteries.

Howdi gang
Now I've noticed for many years that rechargeable batteries always state their capacity on the side. We have some old AA rechargeables that are 1300mAh and some others that are 2300mAh.
Why is it that disposable batteries do not state their capacity? Anyone know or is there a really stupidly simple reason that I'm missing?
I need a new signature... i'm bored of the old one!

Re: Disposable batteries.

Probably to due with internal resistance, which is much higher than rechargeable batteries.
From a Duracell Data sheet for AAA Alkaline batteries
[quote=]Delivered capacity is dependent on the applied load, operating temperature and cut-off voltage. Please refer to the charts and discharge data shown for examples of the energy/service life that the battery will provide for various load condition
