As the name suggests, primary batteries are designed for single-use only. They cannot be recharged and must be discarded once depleted. These batteries typically have a lower energy density compared to their rechargeable counterparts but are widely used in devices like remote controls, toys, and smoke detectors.
Pros:
Cons:
Secondary batteries are the rechargeable workhorses of the battery world. They can be repeatedly charged and discharged, making them a cost-effective option for long-term use. Secondary batteries are commonly found in smartphones, laptops, electric vehicles, and power tools.
Types of Secondary Batteries:
Li-ion batteries are renowned for their high energy density, lightweight, and long lifespan. They are the go-to choice for portable electronic devices, such as laptops and smartphones.
Pros:
Cons:
Lead-acid batteries are the traditional choice for automotive and industrial applications, offering a reliable and durable source of power.
Pros:
Cons:
NiCd batteries are known for their robustness and ability to withstand harsh conditions. They are commonly used in power tools and portable appliances.
Pros:
Cons:
NiMH batteries offer a higher energy density than NiCd batteries and are free from the memory effect. They are often used in portable devices and hybrid vehicles.
