A technician is configuring power management settings and reviewing safety procedures for modern laptop Lithium-ion (Li-ion) batteries. Which TWO of the following statements correctly describe proper Lithium-ion battery management or physical safety protocols? (Select TWO.)
- Configuring battery charge threshold limits (e.g., capping maximum charge at 80%) helps extend overall battery lifespan when plugged into AC power.Cevap
- Swollen battery packs indicate internal gas buildup and must be removed and safely disposed of immediately.Cevap
- CPerforming routine 0% deep discharge cycles weekly is recommended to eliminate memory effect in Lithium-ion cells.
- DPlugging an AC adapter into any physical USB-C port on a laptop guarantees high-wattage Power Delivery charging capability.
- EInternal battery replacement can be performed while connected to AC power as long as the operating system is shut down.
Cevap
Configuring charge threshold limits reduces chemical degradation in Lithium-ion cells, and swollen battery packs represent a thermal hazard requiring immediate removal and safe disposal.
Configuring charge threshold limits minimizes high-voltage exposure on Lithium-ion cells, extending their operating life. Additionally, a swollen battery indicates cell breakdown gas production and requires immediate removal and proper hazardous waste handling.
