A
primary battery is not a secondary battery.
To clarify:
- Secondary batteries are rechargeable. After they discharge, you can recharge them and use them multiple times. Examples include lithium-ion, nickel-metal hydride (NiMH), and lead-acid batteries.
- Primary batteries are non-rechargeable. Once they are discharged, you have to dispose of them and replace them with a new one. Examples include alkaline, zinc-carbon, and lithium primary batteries.
So, if you are looking for which one is
not a secondary battery,
primary batteries like
alkaline would be the answer.
