Secret #1: Laptop Battery Purchaser Caution

Purchasing a laptop cell replacement from a US company often gives you more security and pleasure. 

Many makers promote extremely cheap replacement laptop cell pricing on their websites. Various of these low-cost companies are overseas. They do not follow the same safety and manufacturing regulations as American businesses.

To offer cheaper prices, these businesses frequently:

  • Use substandard components
  • Use haphazard or imprecise security testing processes
  • No customer support agents available in the US
  • Make refunds and exchanges complicated for buyers

The newest Chinese scam technique is to mark batteries with falsely larger capacities than they actually are. Be cautious if you notice the irrelevant prices with the capacities. These merchants are selling fake capacity and inferior products. 

Unfortunately, many buyers do not realize this problem until they replace their batteries. It can be an issue for clients who find that they have to ship a damaged battery overseas. The shipping costs are also much higher than the battery’s value!

When you are looking for a replacement laptop cell, it is crucial to know the following points:

  • If you have any questions about your sale or after-sale issues, you can contact a real business representative.
  • Where the manufacturers process their returns and exchanges (i.e. U.S offices or overseas).
  • The quality of the cells and other components.
  • The guarantee coverage information.
  • The liability coverage in the case of a damaged or faulty cell.

Secret #2: Customers Pay An Additional Fee For Branding and Labeling In Laptop Batteries

Consumers often perceive batteries from Dell, Apple, HP, and other manufacturers as superior mainly due to the name. In fact, even the most famous brand name has components original from other third parties.

This implies that consumers can buy the same high-quality batteries as an aftermarket OEM product. It is for the price’s fraction that they would pay for a great cell – without differences in the quality.

Secret #3: Laptop Battery Components Determine Performance

Laptop batteries consist of three main components:

The factors in each of these sections will affect the overall performance of your battery: quality, longevity, and speed.

Laptop Battery Cells

The cell is the most expensive component of laptop batteries. There are three categories of cells: “A”, “B”, or ”C”. These grades give information about the cells’ durability and performance. 

A ”Grade A” cell will generally live longer and have a higher performance than a ”Grade B” one.

  • Name Brand Cells (Grade A): Several reputable manufacturers like Samsung, LG, and Sanyo have created the standard for cells. 

They have an established track record for performance and safety. You can find most of their cells in the batteries from name-brand businesses, such as Apple, Dell, HP, etc. 

  • Generic/China-made Cells (Grade A): These generic “Grade A” cells are pretty new to the market. Although they have higher quality than lower grade generic cells, there is no adequate data on their performance and safety.
  • Generic/China-made Cells (Grades B and C): These cells are made solely for cheap. They comprise low-quality materials and components. As a result, they have extremely short run times, poor performance, and a short life expectancy. 

These cells are not frequently safety checked. Under some conditions, they can cause computer damage or fires.

Circuit Boards

The circuit board is a small part of batteries that acts as the ”brain”. These circuit boards control the charging and distribution of electricity to the cells. They also take over the work of avoiding overcharging or burning.


The casing of your battery plays an important role in the effectiveness of your replacement battery. It is advisable to use real molds from famous batteries, aiming to produce replacement batteries that will suit your device properly.

Secret #4: Battery Life Expectancy Varies

The laptop battery’s life expectancy varies depending on usage (between 500-800 life cycles). However, high-quality batteries built with quality components have a substantially longer lifespan than batteries manufactured for a low cost.

  • Premium Quality Batteries (Grade A Cells) – 12-20 months
  • Moderate Quality Batteries (Grade B Cells) – 10-16 months
  • Poor Batteries (Grade C Cells) – 5-10 months

Battery Life Expectancy Varies

Secret #5: Laptop Battery Assembly & Testing Procedures Are Not All the Same

Reputable manufacturers conduct Quality Assurance testing on each cell at various stages in the manufacturing process. Meanwhile, lower-tier batteries frequently fail to comply with these testing procedures. Consequently, their products are defective or dangerous to use.

Secret #6: Warranty Coverage For Laptop Batteries

Laptop batteries may degrade sooner than predicted, depending on usage and maintenance. As a result, you should have a comprehensive warranty of your cell for at least one year after sale. 

It is advisable to check the warranty coverage carefully before buying a new cell, too.

Secret #7: Prices Vs Quality

The cost of a certain replacement laptop battery varies a lot based on the attributes we mentioned earlier. It seems absurd to pay a higher price for a famous name brand or the same OEM cell, but you get what you pay for.
