Which battery type is typically used in computers and medical equipment and has also been widely used in hybrid electric vehicles?

• A. Lead-acid
• B. Nickel-Metal Hydride
• C. Lithium-ion
• D. Ultracapacitors

Answer: (B)

Nickel-Metal Hydride batteries have a long track record of safe, reliable performance with a good balance of power and life cycle. This mix made them a common choice in hybrid electric vehicles for many years, since they handle high current and temperature variation well without the safety concerns that can come with some other chemistries. They also appear in portable equipment, including some computers and medical devices, where reliability and durability are prioritized over maximum energy density. While lithium-ion now dominates many modern laptops and medical gear due to higher energy density, NiMH’s widespread historic use in hybrids and its solid safety and ruggedness make it the best fit for this description.
