A laptop battery is the hardware component that powers the device when the computer has no direct connection to a power outlet. Rechargeable batteries enhance laptop portability. An efficient charger comes with an AC adapter that converts alternating current (AC) to direct current (DC). Batteries, chargers and AC adapters have unique features that heighten their performance. Newegg offers a variety of these products for different laptop brands. 

Laptop Battery Technology Enhances Laptop Performance

Heavy-duty laptop batteries can power a specific device for several hours. The amount of time depends on usage and technology. Laptop networking tasks drain batteries more quickly. Nickel-Cadmium (NiCad), Nickel-Metal Hydride (NiMH) and Lithium-Ion (Li-ion) are the technologies employed by most batteries. Li-ion batteries have a long lifespan, and aren't affected by the memory drain. It makes them the most popular of the three battery options, and a popular choice for modern laptops. NiMH batteries have a long lifespan, as well.

Laptop Chargers Are a Key Extension to the Laptop

A device with a drained battery is of no help if the laptop charger is unavailable. This effectively makes the external power component one of the most important computer accessories. Issues with chargers are rare, although problems may arise from physical damage or excess voltage from the power outlet. Laptop batteries work best if charged with a compatible charger. Frequent travelers can use power adaptors for a simple recharge to access their laptop.

Laptop AC Adapters Protect the Computer's Components

Versatile Laptop AC adapters decrease the voltage from the main power supply. The motherboard uses the reduced voltage to keep laptop add-on cards and other laptop components safe. Each adapter has a specific voltage rating that should match the stated laptop voltage requirements.  

Complete Laptop Chargers Are Long Lasting

A laptop charger has two components: the cable from the power outlet to the adapter, and the adapter with the cable that plugs into the device. The compatibility of either charger component to its counterpart ensures simple charging. The cable running from the adapter to the laptop plugs into the device via a connector tip. These vary for different brands of laptops, although cylindrical connectors are the most common. Some modern chargers for laptops employ the USB-C connector system technology that fits the charging port on the portable device. This new system carries significantly more power. 

Keep Charging Sources Up to Date

Charging speeds depend on the AC adapter’s voltage rating, but the age of the battery also comes into play. A cylindrical module known as the ferrite bead lies just before the charger’s connector tip. It is an electromagnetic interference blocker that keeps other digital devices from disrupting normal laptop functions. A rubber shield covers the wiring for long-term use without issues. Most laptop chargers include a movable cord tie, which is convenient for wrapping the accessory and its cables for transport. The adhesive nature of these cord wraps keeps cables from slipping, and their durable material makes them last a long time.
