Is L15S4A02 an Original Lenovo Battery?

The L15S4A02 battery supplied by CARTX should not be described as a genuine Lenovo-manufactured battery unless the specific stock is officially Lenovo-branded and can be verified as such.

The product information supplied for this listing identifies the replacement battery brand as LAP-POWER/TRUST-ME depending on stock, while Lenovo is the compatible mother brand. Therefore, this product is best described as a Lenovo-compatible replacement battery.

This distinction helps customers understand exactly what they are purchasing and prevents confusion between a genuine Lenovo replacement part and a third-party compatible battery.

For official model verification, customers can use Lenovo Support to check their V310-15ISK laptop. Lenovo’s official platform documentation also lists the V310-15ISK configuration and its internal battery specifications.

L15S4A02 Battery Backup Time

The expected backup time of the L15S4A02 Lenovo battery is approximately 2 hours or more, but actual performance varies from laptop to laptop.

For example, a laptop used for web browsing and document editing may provide longer battery life than the same laptop running video editing software, games, high-performance applications, or multiple background processes.

Battery backup also depends on:

• Laptop configuration
• CPU and GPU workload
• Screen brightness
• Wi-Fi and Bluetooth usage
• Windows power settings
• Battery age and condition
• Number of applications running
• Laptop cooling and overall condition

Therefore, the stated 2+ hour backup should be considered an estimated usage range rather than a guaranteed fixed runtime.

First-Time Battery Charging Instructions

When using this replacement battery for the first time, the battery voltage may initially be low. Allow the battery to charge for approximately 6–8 hours before normal use, according to the supplied product instructions.

For the first charging session:

1. Install the battery correctly.
2. Connect the laptop using the original AC adapter.
3. Allow the battery to charge for approximately 6–8 hours.
4. After charging, use the laptop normally.
5. Avoid using an incompatible or low-quality charger.

Using the correct charger is important because the charging system, battery voltage, connector, and laptop charging circuit must work together correctly.
