Single lithium batteries and double lithium batteries for headlamps have their own advantages, and users can choose according to their own needs.
Single lithium batteries are small, easy to carry, and have the same brightness as double lithium batteries. The downside to a single lithium battery is that it has a short lifespan and usually requires carrying a spare battery. Dual lithium batteries are large in size and have a long life, but they are not convenient to carry.
Lithium batteries are a type of battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution. Since the chemical properties of lithium metal are very active, the processing, storage and use of lithium metal are subject to environmental requirements.very high levels. Therefore, lithium batteries have not been used for a long time. With the development of science and technology, lithium batteries have now become mainstream.
