How Batteries Work
Laptop batteries are typically made of lithium-ion cells, which are designed to store energy in the form of chemical reactions. When you charge your laptop, the battery absorbs energy, and when you use it, the energy is released. The battery’s capacity to hold a charge decreases over time due to the natural degradation of the cells. This degradation is influenced by various factors, including the number of charge cycles, depth of discharge, and exposure to extreme temperatures.
Charging Cycles and Depth of Discharge
A charging cycle is completed when the battery is fully discharged and then recharged to 100%. The depth of discharge (DOD) refers to the percentage of the battery’s capacity that’s used before recharging. For example, if you use 50% of your battery’s capacity before recharging, the DOD is 50%. It’s essential to understand that shallow discharge cycles (e.g., 80% to 100%) are less stressful on the battery than deep discharge cycles (e.g., 0% to 100%).
