Computer & Laptop Batteries

The last thing laptop users want are batteries that don't perform optimally. When choosing batteries for laptops, it's important to look at features that make the battery and the laptop perform well. This includes determining if a battery is long-lasting and doesn't overheat. Does a battery withstand high-performance activity? The battery should also match the computer model and brand as there are no universal batteries. Browse Staples to find batteries that fit your laptop. 

Main considerations when buying batteries for laptops
When getting a replacement battery for a laptop, always check the brand and model number of the computer. Laptop batteries are specific to models, hence the need to note down the battery model and number. It's also important to choose a battery for a laptop that holds a charge and has a longer life. A good performing battery can hold its charge at least three hours without the need to recharge. Other batteries may last for longer or shorter periods, depending on the technology used.

Make sure to purchase a battery that doesn't overheat and can sustain long hours of computer activity. A laptop battery that overheats is dangerous for the user and can damage a computer. Batteries that can hold a charge without heating up also last longer.

Reading the correct model number of a battery for a laptop
Some of the batteries for laptops come with screws to attach to the inner bottom of a computer, and the user will need to open a big section of the laptop. Others are easy to unplug with sliding clips and hooks. The alphanumeric code of the model is either pinned below the casing for the battery or the user might need to remove the battery to access the code. Once the code is visible, use it to find a suitable replacement. It's also possible to get the correct battery model by checking the computer brand and model so you can find a compatible battery.

How do you estimate the battery life before buying?
It's possible to calculate the number of hours a battery for a laptop can last. Various formulas can determine usage as well as the amount of power needed. For example, divide the battery watt-hours with the estimated wattage. This is the number of watts a computer requires per hour. It gives the expected hours a battery can last.

Can you replace a low voltage battery with a higher voltage one?
Some computers are compatible with models that are of higher capacity. When choosing this, check whether this extra power will affect the performance of a computer. A higher wattage battery will consume more power but will most likely last longer from a charge. The upgrade should be on capacity rather than the voltage.

Is the technology used to make batteries the same?
Batteries for laptops are different in make and assembly. Most of the batteries are Li-on, but there are others such as NiCad and NiMH, which use different technologies. When choosing a battery, consider the technology used by the previous battery.
