Choosing between rechargeable batteries (secondary batteries) and non-rechargeable batteries (disposable batteries) depends on a variety of factors. If the device needs to replace batteries frequently, rechargeable batteries may be more economical because they can be reused. If it is for occasional use or temporary needs, disposable batteries may be more convenient. Although the initial cost of rechargeable batteries is higher, the overall cost is lower in the long run because they can be recharged repeatedly. Disposable batteries are cheap, but they need to be replaced frequently in the long run, and the cumulative cost may be higher.

Rechargeable batteries (secondary batteries)

are batteries that can be charged and discharged repeatedly. Common ones include lithium-ion batteries, nickel-cadmium batteries, nickel-metal hydride batteries, etc.

Advantages
- High energy density: can provide more power, allowing the device to run longer.
- Long cycle life: can provide thousands of charge and discharge cycles.
- Fast charging: some battery types support fast charging technology.
- Low self-discharge rate: even if not used for a long time, the battery can maintain a high charge.
- Environmental protection: because it can be reused, it reduces the impact of discarded batteries on the environment.

Disadvantages
- Higher cost: The initial purchase cost is higher than that of disposable batteries.
- Heavy weight: Rechargeable batteries are usually heavier than disposable batteries.
- Requires proper maintenance: Improper charging or discharging may shorten the battery life.

Non-rechargeable batteries (primary batteries)
Are batteries designed for one-time use and cannot be recharged after use. Common ones include alkaline zinc-manganese batteries, zinc-silver batteries, zinc-air batteries, etc.
Advantages
- Cheap price: Disposable batteries are usually cheaper than rechargeable batteries.
- Easy to carry: Lightweight and easy to use.
- Ready to use: No need to charge, it can be used out of the box.
Disadvantages
- Disposable use: Need to be discarded after use, long-term use costs are higher.
- Environmental pollution: Disposable batteries may pollute the environment.
- Lower capacity: Disposable batteries usually have less power than rechargeable batteries.
