How to know the laptop battery is new and authentic?

To determine whether a laptop battery is brand new and genuine, a comprehensive assessment from multiple aspects is required.

How to distinguish the authenticity and newness of laptop batteries

Look at the battery appearance

Genuine batteries usually have a big difference in appearance and packaging from refurbished batteries and fake batteries. The appearance and packaging of genuine batteries are brand new and undamaged, while refurbished batteries will definitely show signs of having been used.

Look at the thickness of the battery shell

The shell of a new battery is thicker, and you can feel the hardness of the shell by pressing hard. Most refurbished batteries have polished shells, which are relatively thin.

Check the production date and anti-counterfeiting label

New batteries have a clear production date, and there are no signs of grinding on the date. Refurbished batteries have signs of grinding on the date, or even no production date. In addition, some brand batteries have corresponding anti-counterfeiting labels, which can be scanned for verification.

Look at the battery connection port

The wiring connectors of genuine batteries generally show no signs of use; however, refurbished batteries have been returned to the factory for repair for the second time and will already have signs of use .

Check the certificate and warranty card

Regular new batteries have their own certificates and warranty cards. Some unscrupulous dealers may deceive users by saying that they can provide discounts without certificates and warranty cards. Be careful to distinguish them.

Check the battery production date

Many customers don’t know that the battery also has a production date, but in fact the production date of the battery can be seen on the plastic shell.

If the battery’s production date is close to the present, it means that the battery is the latest to be produced; if the battery’s production date is several years ago, customers need to be vigilant.

Because the battery will be consumed during this period of time, some old batteries are usually sold at a discount on the market.

Beware of cheap batteries

If users come across a low-priced well-known battery, they should be more cautious because it is likely to be a counterfeit or refurbished battery.

Battery detection

In the opened battery report, you can see a lot of information, such as recent usage records, battery consumption records, usage history, battery capacity history, battery life estimation, etc.

The theoretical number of cycles for lithium batteries is generally 400-500 times (i.e. lifespan), and this refers to deep discharge, not just counting when the charger is plugged in. If it is not often charged at the critical point, the actual number of cycles is often 1000+.

The battery of a new computer (new battery) generally has a loss ratio of no more than 5%, and a cycle count of no more than 2 times, otherwise the battery is not new.

If the loss ratio is above 20%, it is basically defined as damaged, but still usable; if the loss ratio is above 40%, it may cause abnormal power supply or power outage, and it is recommended to replace it immediately.

For consumers, when purchasing electronic products and accessories, they should try to choose regular channels to purchase and avoid purchasing from online stores or individuals of unknown sources.

At the same time, we should improve our anti-counterfeiting awareness and learn common methods to identify genuine and counterfeit products, such as checking product packaging, labels, serial numbers, etc. If necessary, we can contact the brand official for verification. If there is a problem with the purchased product, we can immediately report it to the relevant platform or department to protect our own rights and interests.
