A laptop originally uses an 11.1 V lithium-ion battery. While on-site, a technician receives a replacement battery of the correct shape and connector but marked 14.8 V. Which of the following should the technician do NEXT?
Flash the BIOS to the latest version to ensure compatibility, then install the battery.
Adjust the Windows power plan to limit performance, then install the battery.
Install the 14.8 V battery; the laptop will automatically regulate the voltage.
Do not install the battery and order one with the correct voltage rating.
The technician should not install a battery whose voltage rating falls outside the manufacturer-specified range. A higher-voltage battery can overheat components, damage the charging circuitry, and create a fire risk. Instead, the technician should order a battery that matches the original voltage (or the manufacturer-approved voltage pair such as 10.8 V/11.1 V). Installing the mismatched battery or attempting software work-arounds will not correct the electrical incompatibility.
