However, they may have a lower voltage output and shorter life per charge than disposable types. Understanding Voltage in 9V Batteries Voltage is the measure of electrical potential between two points. For 9V batteries, it indicates the energy level of the battery.
Batteries & Output Current Limiting
Your first assumption "battery capable of delivering 1000mAh is also capable of delivering 1Ah, or 2A for 1/2 hour, 4A for 1/4 hour" is incorrect. (That has been answered here already, I will have a look for it.) The battery capacity vs discharge is far from linear, and the mAh rating is quoted against a low discharge rate (~0.1*capacity).

Whether a battery is a constant voltage source or current source
A battery is considered to be a voltage source because the galvanic activity they use to store and deliver energy has a fixed voltage across it. However, a …
Battery, current and voltage
The voltage of a battery does not determine its capacity (Amp-Hours). Also, current is dependant on voltage. V=I*Z. A battery is a DC voltage source, not a current source. So saying that a 1.5V battery would supply the …
18650 Li-ion Cell Pinout, mAh, C Ratings & Datasheet
What is C rating and mAh of a battery? While working with batteries, the two most common terms you will come across is the mAh rating and the C rating. An 18650 cell rated at 2850mAh means that when we consume 2.850A from the battery it will last for 1 hour and similarly if we consume only 0.285A from the battery it will last for 10 hours so …
