Understanding Laptop Batteries

Types of Laptop Batteries

Most modern laptops use lithium-ion batteries because of their high energy capacity and lightweight design. There are also nickel-cadmium (NiCad) and nickel-metal hydride (NiMH) batteries, but these are less common due to their heavier weight and lower energy densities.

Signs of Battery Aging

Batteries age, losing capacity over time. If your laptop doesn’t last as long on a full charge as it used to, or if you see a red X over the battery icon on your Windows device, it’s a signal that the battery’s capacity is dwindling. Other serious signs include physical deformations, such as a swollen battery, which can be hazardous.

Battery Life and Capacity

The battery life of a laptop is how long it can run before needing a recharge. Capacity refers to the maximum charge a battery can hold. With age and usage, capacity drops, meaning your laptop may not run as long as when it was new. Keeping an eye on the battery capacity and the number of charge cycles helps gauge lifespan.
