The portability of laptops is inseparable from the support of batteries, but the numerous battery manufacturers on the market make many users confused when purchasing. In fact, the secrets hidden behind the laptop battery factory are the key to our purchase.

Battery capacity

Battery capacity is a key indicator to measure the battery life of laptops, usually in milliampere hours (mAh).

Many customers reported that after receiving the purchased laptop battery, they found that the actual battery capacity tested was different from that on the label. Today, I will teach you how to identify some "tricks" that falsely report battery capacity.

Please continue reading, the following methods are provided for you to choose and test according to actual conditions.

‌Discharge test‌

A method of measuring the actual capacity of a battery by completely discharging it. The battery is discharged using a constant current, the discharge time is recorded, and the battery capacity is then calculated using a formula .

‌Charging Test‌

Charge the battery to full capacity and record the charge level to estimate the actual capacity of the battery.

‌Using a Coulomb Counter

A coulomb meter is an instrument specifically used for measuring electrical quantity. It can accurately measure the charging and discharging current and quantity of a battery, thereby calculating the actual capacity of the battery.

This method is more suitable for professionals. Ordinary users do not need to buy such equipment specifically to test batteries worth dozens of dollars.

‌Pay attention to battery voltage changes‌

Monitoring the voltage changes of the battery at different discharge stages can indirectly determine the capacity status of the battery. Generally speaking, the faster the battery voltage drops, the lower the actual capacity of the battery.

‌Check the battery appearance and markings‌

After receiving the express package, customers can check the production date, batch, capacity mark and the clarity of the safety certification mark to determine whether it is from a regular manufacturer. If the battery has a rough appearance, blurred marks or lacks important information, be vigilant.

‌Compare parameters and capacity

Compare the battery to be tested with the original battery or a battery with known accurate parameters, check the rated capacity, voltage and other information marked on the battery, and actually test its usage time under the same conditions‌.

‌Weight and volume check

By comparing the physical size and weight of the battery, we can judge the actual battery capacity it may contain. With the same specifications, the larger the battery capacity, the more electrode materials it needs to accommodate, so the weight and volume will increase accordingly.

Through the above method, consumers can more accurately judge whether lithium batteries are falsely labeled and avoid purchasing battery products of poor quality or with safety hazards.

Battery Type

Laptop batteries are mainly divided into two types: lithium-ion batteries and lithium-polymer batteries.

Lithium-ion battery

Lithium-ion batteries are the most common type of batteries at present, with advantages such as high energy density and long cycle life. However, lithium-ion batteries are sensitive to ambient temperature, and high or low temperature environments will affect their performance.

Lithium polymer battery

Lithium polymer batteries are an upgraded version of lithium-ion batteries, with advantages such as higher safety, lighter weight and more flexible shape, etc. However, the cost of lithium polymer batteries is also relatively higher.

Laptop Battery Buying Guide: How to Choose a Quality Battery

Focus on brand and reputation

Choosing well-known brands and reputable battery products can effectively reduce the risk of purchase.

The Kingsener brand has nearly ten years of experience on major e-commerce platforms and is recognized and trusted by the majority of buyers. We will provide more complete after-sales services, such as longer warranty periods and more convenient repair services.

View product parameters

Read the product parameters carefully, pay special attention to the battery capacity , voltage, size and other parameters, ensure compatibility with your laptop, and choose a product that meets your needs.

Learn about product certification

Choosing products that have passed relevant certifications, such as CE, FCC, UL, etc., can ensure product quality and safety.

Pay attention to the appearance and packaging of the battery

High-quality batteries usually have exquisite appearance and packaging, and will not have obvious defects. Merchants generally pack their products very tightly to prevent damage during transportation.

Pay attention to battery prices

A reasonable price means that the cost of the battery matches its performance, life and safety.

If the price of a battery is too high, it may not be accepted by consumers even if it has excellent performance.

Conversely, if the price of a battery is too low, it may mean that there is a problem with its quality, such as the use of inferior materials or a shortened lifespan.

Consult professionals

Before purchasing, you can consult a professional to understand the advantages and disadvantages of different brands and models and choose the product that suits you best.
