Is it better to buy a lithium battery or a lead-acid battery?
There are advantages and disadvantages to buying lithium batteries and lead-acid batteries. Here are some comparisons. You can choose according to your specific needs:
Performance:
Battery life: Generally speaking, lithium batteries have a longer battery life. At the same volume or weight, lithium batteries have a higher energy density, can provide more power, and have a relatively longer range. For example, in electric bicycles, models using lithium batteries usually have a longer range than models using lead-acid batteries. If you have high requirements for the range of your equipment, lithium batteries may be more suitable.
Charge and discharge performance: Lithium batteries have higher charge and discharge efficiency, relatively fast charging speed, and support high current discharge. Lead-acid batteries have a longer charging time and relatively small charge and discharge current. However, lead-acid batteries do not have strict charging method requirements and are relatively more "tough".
Battery cycle life:
Lithium batteries usually have a longer service life than lead-acid batteries. Under normal use, the number of charge and discharge cycles of lithium batteries can reach more than a thousand times, while the number of charge and discharge cycles of lead-acid batteries is generally around 300-500 times. If you want the battery to last longer and replace less frequently, lithium batteries are a better choice.
Safety:
Lead-acid batteries have a simpler internal structure and relatively stable chemical properties, so the probability of explosion and other dangerous situations is low. If the protection circuit design of the lithium battery is unreasonable or improperly used, it may cause problems such as spontaneous combustion. However, lithium batteries produced by regular manufacturers have perfect protection measures, and as long as they are used correctly, their safety is guaranteed.
Volume and weight:
Lithium batteries are small in size and light in weight. This is very important for some scenarios that require device weight and volume, such as portable electronic devices and electric bicycles. In contrast, lead-acid batteries are larger in size and heavier in weight, and are not suitable for occasions with high portability requirements.
Environmental protection:
Lithium batteries have more advantages in environmental protection. Lithium batteries do not contain toxic and harmful heavy metal elements such as lead, mercury, and cadmium, and the pollution to the environment during production, use and scrapping is relatively small. Lead-acid batteries contain heavy metals such as lead, which will pollute the environment if not handled properly.
To sum up, if you focus on driving range, service life, safety, portability and environmental protection, then bettery lithium battery is a better choice. As a large lithium battery manufacturer, Bettery has 27 years of lithium-ion battery research and development technology. Whether it is high-capacity lithium battery, wide-temperature lithium battery, high-rate lithium battery, etc., we can customize lithium battery products of different types and specifications according to customer needs.
