What Type of Battery Is Commonly Used in Laptops?
Laptops commonly use lithium-ion (Li-ion) batteries.
- Lithium-ion (Li-ion) batteries
- Lithium polymer (LiPo) batteries
- Nickel-metal hydride (NiMH) batteries
- Nickel-cadmium (NiCd) batteries
Lithium-ion (Li-ion) batteries dominate the laptop market due to their efficiency and lightweight nature.
-
Lithium-ion (Li-ion) batteries:
Lithium-ion (Li-ion) batteries are rechargeable batteries that utilize lithium ions as the primary charge carrier. These batteries offer high energy density and long cycle life, making them suitable for portable electronics like laptops. According to a report by QYResearch (2021), Li-ion batteries account for over 70% of the global laptop battery market. For example, a typical laptop battery may have a capacity ranging from 30Wh to 100Wh, depending on the laptop model and manufacturer. -
Lithium polymer (LiPo) batteries:
Lithium polymer (LiPo) batteries are similar to Li-ion batteries but use a polymer electrolyte instead of a liquid one. This design allows for lighter and thinner battery designs. LiPo batteries offer flexible shapes and sizes, which can be advantageous for ultrathin laptops. However, they typically have a lower energy density compared to Li-ion batteries. A study by Battery University (2022) highlights that while LiPo batteries are becoming more common, they are still less prevalent than Li-ion in laptops. -
Nickel-metal hydride (NiMH) batteries:
Nickel-metal hydride (NiMH) batteries are rechargeable batteries that use nickel and hydrogen. They were once popular in laptops but have largely been replaced by lithium-based technologies. NiMH batteries have lower energy density and higher self-discharge rates than Li-ion batteries. Their usage is now more common in older laptop models or some budget devices, according to the International Energy Agency (IEA, 2019). -
Nickel-cadmium (NiCd) batteries:
Nickel-cadmium (NiCd) batteries are another older technology. They contain cadmium and nickel and are rechargeable but have lower energy density and are less environmentally friendly due to cadmium’s toxicity. NiCd batteries are rarely used in modern laptops but may still be found in some legacy devices. Their major drawback is the “memory effect,” where the battery loses capacity if not fully discharged before recharging, as discussed by the U.S. Department of Energy (2020).
Overall, lithium-ion batteries remain the preferred option for laptops due to their performance, weight, and longevity.
What Are the Different Types of Laptop Batteries and Their Features?

The energy density is often higher, allowing for longer usage times before recharging. However, they tend to be more expensive to produce, which could result in higher laptop costs. A report by the International Journal of Engineering & Technology indicates that Lithium-Polymer batteries can also be less durable compared to their Lithium-Ion counterparts. -
Nickel-Metal Hydride:
Nickel-Metal Hydride (NiMH) batteries are less common in laptops today. While they are more environmentally friendly than Nickel-Cadmium batteries, they typically offer lower energy density and higher self-discharge rates. This means they lose charge more quickly when not in use. According to a comparison study by the Battery technology Journal, NiMH batteries also have a shorter life cycle than Lithium batteries, generally lasting around 300-500 charge cycles. -
Nickel-Cadmium:
Nickel-Cadmium (NiCd) batteries are one of the oldest battery technologies. They were commonly used but are now largely obsolete in laptops due to their environmental hazards, such as cadmium toxicity. NiCd batteries offer good performance for high-drain devices but have a lower energy density compared to modern alternatives. They also suffer from the “memory effect,” which leads to reduced capacity if the battery is not fully discharged regularly. As per the Environmental Protection Agency, NiCd disposal is strictly regulated to prevent environmental pollution.
Understanding these battery types helps users select the right laptop based on their needs and sustainability preferences. Each type presents distinct advantages and disadvantages that can influence battery performance and longevity.
How Do Lithium-Ion Batteries Compare to Lithium Polymer Batteries?
Lithium-ion batteries and lithium polymer batteries differ primarily in their structure, performance, and applications, with lithium-ion batteries typically offering higher energy density while lithium polymer batteries provide more flexibility in design and lighter weight.

3. Reduced memory effect
4. Shorter lifespan
5. Higher self-discharge rates
6. Limited performance in extreme temperatures
The advantages and disadvantages of NiMH batteries highlight their strengths and weaknesses, which influences their applications in various fields.
-
Higher Energy Density:
Higher energy density refers to the ability of NiMH batteries to store more energy relative to their size and weight, compared to older technologies like Nickel-Cadmium (NiCd). NiMH batteries can deliver approximately 30% more capacity than similarly sized NiCd batteries. This characteristic makes them suitable for applications in hybrid vehicles and consumer electronics, where space and weight savings are critical. According to a study by the Department of Energy (DOE) in 2019, hybrid vehicles utilizing NiMH technology achieved better fuel efficiency due to the enhanced energy stored in the battery pack. -
Better Environmental Impact:
Better environmental impact signifies that NiMH batteries are generally more environmentally friendly than NiCd batteries. NiMH batteries do not contain toxic cadmium, which requires careful disposal due to its environmental hazards. As per the EPA, the use of NiMH reduces heavy metal pollution. Furthermore, NiMH batteries can be recycled, contributing to a reduced carbon footprint. Research from the journal Environmental Science & Technology (2021) emphasizes that opting for NiMH batteries over conventional options can lessen harmful waste in landfills. -
Reduced Memory Effect:
Reduced memory effect refers to NiMH batteries’ improved performance in regards to charge retention. Unlike NiCd batteries, which suffer from memory effect—where the battery loses its maximum energy capacity if charged before fully depleted—NiMH batteries experience significantly less of this phenomenon. This trait allows for more flexible charging patterns and ensures consistent performance over time, making them suitable for devices that are frequently charged and used, such as cameras. -
Shorter Lifespan:
Shorter lifespan indicates that NiMH batteries typically have a shorter operational life compared to lithium-ion batteries. While NiMH batteries can endure approximately 500 to 1000 charge cycles, lithium-ion batteries can last between 1000 to 2500 cycles. This shorter lifespan can lead to increased costs in applications requiring frequent battery replacements. According to a report by Battery University (2020), the limited lifespan of NiMH batteries can be a deciding factor for users in portable electronic devices. -
Higher Self-Discharge Rates:
Higher self-discharge rates mean that NiMH batteries lose their charge more quickly when not in use compared to lithium-ion alternatives. The self-discharge rate for NiMH batteries can be as high as 30% per month, while lithium-ion batteries tend to hold their charge for much longer, approximately 5-10%. This characteristic can be disadvantageous for devices that are infrequently used. A study by Schneider Electric (2021) warns that users should be aware of this attribute when selecting batteries for long-term storage devices. -
Limited Performance in Extreme Temperatures:
Limited performance in extreme temperatures signifies that NiMH batteries may not perform optimally in very low or high temperatures. They tend to lose capacity more quickly in colder climates, which can lead to reduced efficiency in cold weather applications. This limitation is noted by the International Journal of Energy Research (2020), concluding that these environmental factors can influence the performance and effectiveness of NiMH batteries in specific working conditions.
