CompTIA A+ Core 1 (220-1001) — Question 149

A user requests a new laptop battery that will yield a longer run time. The user's current battery has the following information printed on it:
14.8V 6-cell 1800mAh lithium ion battery
Which of the following battery specifications will yield a longer run time but still be compatible with the current laptop?

Answer options

• A. 14.8V 6-cell 1800mAh nickel cadmium battery
• B. 14.8V 6-cell 2200mAh lithium ion battery
• C. 14.8V 9-cell 1800mAh lithium ion battery
• D. 19.2V 6-cell 1800mAh lithium ion battery

Correct answer: B

Explanation

Option B is correct because it has a higher capacity of 2200mAh, which translates to longer run time while still being a compatible lithium ion battery. Option A uses nickel cadmium, which has different characteristics and may not be compatible. Option C has a higher cell count but the same capacity, and option D has a different voltage, making it incompatible.
