Best battery life laptop

Anyone considering buying a new laptop or as a gift should remember that while speed and design are important, many people care about battery life. After all, nothing is worse than shutting down laptops during large conferences, writing an important email or streaming the latest carnival Netflix series.The good news is that it's now easy to find laptops and 2-in-1 hybrids with a battery life of 10 hours or more. This is due to improvements in the Intel Core i-series CPUs, as well as power and thermal management improvements in Windows 10 and MacOS.Based on a large number of battery tests conducted at CNET Labs, these are the 25 PCs with the longest battery life score from the fall of 2016 to the current year. This list includes Windows and MacOS laptops, Windows 2-in-1 hybrids, and Chromebooks running Google Chrome OS. Does not include Android or iOS tablets.New additions to this latest update include the Lenovo Yoga 920, which can be upgraded to Intel's latest eighth-generation CPU, and the latest MacBook Air, which received a small CPU update in early 2017. Please note that Microsoft's recent Surface Book 2 has two separate batteries, one on the tablet and the other on the keyboard base. We ran them together for up to 17 hours, but we have inconsistent battery performance on the system, and we are conducting further testing before considering inclusion in this list.

What is the difference between a NiCad battery and a NiMH battery?

NiCad (nickel cadmium) batteries are best known for their battery type with memory effect. In order for these batteries to work effectively, the battery must be fully discharged before charging. If you charge these batteries while they still have battery power, the battery resets itself so that you can only retain the amount of power stored during the last charge. Many electric toothbrushes, power tools and other consumer products still use NiCad battery chemistry. If your device is equipped with a nickel-cadmium battery, you can save some trouble and money with a fully charged spare battery when charging a depleted battery. NiCad battery has the lowest production cost, but due to memory effect problems,NiMH batteries are less prone to this problem and require less maintenance and adjustment. In addition, NiMH batteries can store twice as much energy as NiCad batteries without adding extra weight. NiMH batteries are also more environmentally friendly than NiCad batteries because they do not contain heavy metals (there are serious landfill problems). Note: Not all devices accept NiCad and NiMH batteries.

The benefits of large capacity batteries

A large capacity laptop battery is provided, allowing you to use longer runtimes between charges.Battery capacity in ampere-hoursStandard capacity batteries are typically rated at approximately 4.4Ah, and our high-capacity batteries range from 6.6Ah to 8.8Ah. The actual size depends on the original manufacturer's original specifications.In order to increase the storage capacity, the physical size of the battery usually increases.E.g. If your standard battery is a 4.4Ah or 6 Cell model, the 8.8Ah version will contain 12 batteries.(Cell = each battery installed in the laptop battery, these batteries are very similar to the standard AA batteries we use in consumer devices.)In order to accommodate additional batteries, high-capacity batteries are larger and heavier.You need to consider these two factors when purchasing a high-capacity battery.If your baggage is only designed to accept standard batteries, laptops with high-capacity batteries may no longer be suitable for your laptop bag.Also, if you do a lot of travel (aircraft), you may want to consider the extra weight and its impact on carry-on baggage.

How is the battery rated? (What is volts and amps)

Each battery has two grades: volts and ampere hours (AH or mAH). Unless the battery has a different chemical composition (NI-MH and Li-Ion batteries have different voltage ratings, even if they are used on the same laptop), the voltage of the new battery should match its original voltage. Most of our batteries have an ampere hour rating that is higher than the original battery in the device. This means that the runtime is longer (higher capacity) and does not cause any incompatibilities.

What is the life of the new battery?

The life of a rechargeable lithium ion rechargeable battery under normal conditions is typically about 500 charge/discharge cycles. This means that the average user's battery life is one and a half to three years. As the rechargeable battery begins to die, the user will notice a drop in battery run time. When the battery that initially operated the laptop for three hours was only used for one hour by the user, it was time to replace the battery.

How long does the new battery power the laptop?

This is hard to determine. The actual battery runtime depends on the power requirements of the device. In the case of laptops, the use of monitors, hard drives and other peripherals can cause extra battery drain and effectively reduce battery run time. The total operating time of the battery also depends to a large extent on the design of the device.In general, our new high-capacity batteries can use the old battery for a long time (the most common is 20-50%).

How to care for your laptop’s battery

Who doesn’t have a love/hate relationship with their laptop battery? It lets us be mobile, but it also chains us to that little battery life gauge and the dreaded decay of performance as time goes on.All laptop batteries are built to handle a certain number of charge cycles, usually somewhere around 500 full cycles — and sometimes even more. Essentially, a charge cycle equals one full discharge down to zero percent and then a recharge back up to 100 percent. A discharge down to 50 percent and then back to 100 percent would equal half a cycle. Over time, each charge cycle decreases a battery’s capacity from its design specifications, meaning that the fewer times you drain it, the longer the battery last — all other things being equal.
