Actually, it’s the other way around!
Primary batteries are
not rechargeable, while
secondary batteries are.
Here’s a quick breakdown:
- Primary batteries: These are designed for single-use. Once the chemicals inside have been used up, the battery can’t be recharged and must be replaced. Examples include AA, AAA, and most disposable batteries.
- Secondary batteries: These are rechargeable. You can use them, recharge them multiple times, and reuse them. Examples include lithium-ion (Li-ion) batteries, lead-acid batteries, and nickel-metal hydride (NiMH) batteries.
So, primary = non-rechargeable, secondary = rechargeable!
