If you choose to use a regular battery instead of a lithium battery, you may face the following:
Shorter battery life:
Regular batteries, such as alkaline or nickel-cadmium batteries, typically have a lower energy density, which means they store relatively little energy. As a result, electronic devices that use regular batteries may not work as long as they do with lithium batteries and need to replace batteries more frequently.
Heavier weight:
Regular batteries have a lower energy density, and in order to get the same amount of battery life as with lithium batteries, a higher number of batteries or a larger battery capacity may be required, which increases the overall weight of the device.
Short service life:
Ordinary batteries, especially rechargeable batteries such as nickel-cadmium batteries, have a memory effect, which affects the capacity and service life of the battery. Lithium batteries don’t have this problem.
Different charging needs:
If you choose a rechargeable ordinary battery, such as a nickel-cadmium battery or a nickel-metal hydride battery, they may require a special charging method and charger, which is different from the charging method of lithium batteries.
Potential environmental impact:
Some ordinary batteries, especially those containing heavy metals, may cause pollution to the environment if not handled properly. Lithium batteries generally perform better when it comes to environmental friendliness.
Cost considerations:
While lithium batteries may be more cost-effective for the initial purchase, they may be more cost-effective in the long run given their longer lifespan and higher energy density. Regular batteries may need to be replaced more often, increasing the overall cost.
Safety and performance:
Lithium batteries have high energy density and stable discharge performance, which is suitable for high-performance electronic devices. Whereas, a normal battery may not perform well in these areas, affecting the overall performance of the device.
In summary, choosing a regular battery over a lithium battery may result in shorter battery life, heavier equipment, shorter lifespan, different charging needs, potential environmental impacts, and possible cost and performance issues. However, in some specific applications or budget constraints, a regular battery is still a viable option. When choosing a battery, it should be considered comprehensively based on the specific needs and budget of the equipment.
