FAQ:
Q:What is special about lithium batteries?
A：With high energy density, it has reached 460-600Wh/kg, which is about 6-7 times that of lead-acid batteries. Long service life, life span can reach more than 6 years. Light weight, the weight is about 1/5-6 of the lead-acid product under the same volume
Q:What is a lithium battery used for?
A:Lithium battery use for power and energy storage. Like emergency power backup or UPS. Dependable electric and recreational vehicle power,golfcart,reliable and light-weight marine,solar power storage,surveillance or alarm systems in remote locations.
Q：What is the difference between a lithium battery and a lithium-ion battery?
A:It mostly comes down to the fact that lithium-ion batteries are rechargeable while lithium batteries are single-use. Lithium battery have a higher energy density than lithium ion batteries.
Q:Which battery is better alkaline or lithium?
A:Lithium batteries are lighter than alkaline batteries, so they offer an advantage when used with portable devices, especially cordless power tools.A lithium battery can be used as a high-performing alternative to a standard alkaline battery. Lithium battery designed to last longer,making them a good choice for high-tech and smart devices. They can withstand extreme low temperatures. Lithium can operate without failing in a very cold climate, so it’s ideal for outdoor applications.
