BATTERY FACTS EXAM QUESTIONS WITH 100%
RATED ANSWERS, GET A+
What are mobile devices, including laptops, typically powered by? - Mobile devices including
laptops are powered with a battery. Battery technology has significantly advanced over the past
20 years.
What happens to Nickel cadmium (NiCd) batteries when recharged repeatedly? - NiCd batteries
develop a memory and begin to store less power over time. To avoid this, the battery should be
completely drained before recharging.
What is a major drawback of NiCd batteries in terms of size and heat sensitivity? - NiCd
batteries take up more physical space than newer battery technologies. They are also very heat
sensitive.
Are NiCd batteries still used in new laptops? - NiCd batteries are no longer used on new laptops.
Their drawbacks have made them obsolete for modern devices.
Do Nickel metal hydride (NiMH) batteries develop a memory? - NiMH batteries do not develop
a memory. This improves their longevity and efficiency compared to NiCd.
How does the lifetime of NiMH compare to NiCd batteries? - NiMH batteries have a 40% longer
lifetime than NiCd batteries. This makes them a better choice for long-term use.
What is the charge capacity of NiMH batteries compared to NiCd? - NiMH batteries have a
greater charge capacity than NiCd batteries. This allows them to hold more energy for longer
periods.
How does the toxicity of NiMH batteries compare to NiCd? - NiMH batteries are less toxic than
NiCd batteries. This makes them more environmentally friendly.
Are NiMH batteries more expensive than NiCd batteries? - Yes, NiMH batteries are slightly
more expensive than NiCd batteries. However, their benefits often justify the cost.
