battery
Let an agent identify a battery by chemistry, size and use, relay specifications, safety, charging, transport and recycling rules from manufacturers and regulators, and separate batteries from cells, chargers and fuel cells.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent identify a battery by chemistry, size and use, relay specifications, safety, charging, transport and recycling rules from manufacturers and regulators, and separate batteries from cells, chargers and fuel cells.
A device that stores chemical energy and delivers it as electric current through one or more electrochemical cells, either single-use primary cells or rechargeable secondary cells such as lead-acid, nickel-metal hydride and lithium-ion, in sizes from button cells to vehicle packs and grid storage.
What it is for: Storing and delivering electrical energy.
It can be identify chemistry, format and capacity; explain how it works and how it ages; relay safety, charging and transport rules; relay disposal and recycling requirements.
Distinguishing features
Electrochemical storage, unlike a capacitor
Primary versus rechargeable
Chemistry sets voltage, energy density and hazards
Ageing and state of health change capacity over time
What it looks like
A sealed cylinder, prism, pouch or box with two terminals, marked with chemistry, voltage and capacity.
Physical character
cell voltage: 1.2-3.7 V - by chemistry
capacity: milliampere-hours to megawatt-hours Ah or Wh - from button cells to grid storage
cycle life: hundreds to thousands cycles - rechargeable chemistries; depends on use
How it is recognised
Markings give chemistry, nominal voltage, capacity and size code
Rechargeable packs carry charge and safety markings and often a management circuit
A fuel cell or a capacitor is a different device
