Secondary cells are sometimes referred to as rechargeable batteries. Rechargeable batteries can be recharged by applying an electric current that is directed in the opposite direction of the discharge current. Rechargeable cells are utilized for high-power applications and have stronger power output capabilities than primary cells; primary cells have a greater capacity for storing energy. The advantage of rechargeable batteries is that they have a long service life. Environment-friendly, cost-effective, convenient, and high-drain application. The disadvantages of rechargeable batteries are their higher price, recycling issues, state of charge indicator, charging time, and battery performance deterioration.
Advantages of Rechargeable batteries
- Rechargeable batteries can be used repeatedly over an extended period.
- The sense of security that rechargeable batteries provide allows you to relax and wait patiently for them to fully recharge.
- Rechargeable batteries have better power output capabilities compared to primary cell.
- Rechargeable batteries are more environmentally friendly than other types of batteries.
- Rechargeable batteries are more economical since they last longer, even if they are more expensive than primary or waste batteries.
- According to estimates, they have a 25% lower impact on air pollution, a 10% lower impact on water pollution, and a 7% lower impact on air acidification. They are not only reusable, but they also produce less trash in the long run.
Disadvantages of Rechargeable batteries
- Rechargeable batteries have a higher initial cost than primary batteries.
- Rechargeable batteries are less suited for usage as the main energy source due to their self-discharge characteristics.
- Some users may find it inconvenient to have to wait for the battery to charge before using it.
- Rechargeable and secondary batteries are problematic to dispose of even though they take longer to do so because of the chemicals they contain.
- Rechargeable batteries may lose performance over time as a result of aging and become unpredictable in strength.
