Answer: A - If you have just purchased a new laptop, it most likely came with a Lithium-ion battery.

Key Takeaway: Lithium-ion (Li-ion) batteries are the most common type of battery found in laptops today. Unlike Nickel-metal hydride (NiMH) and Nickel-cadmium (NiCd) batteries, which could lose potential battery life if the battery was charged when only half-full, the Li-ion battery lasts longer and will not develop a “memory.”
