Understanding the Lenovo IdeaPad Slim 3 15ITL6 Battery

The Lenovo IdeaPad Slim 3 15ITL6 is equipped with an internal lithium-polymer battery that comes in two main variants: a 38Wh and a 45Wh version. Both types support Lenovo’s Rapid Charge technology, which allows the battery to charge up to 80% in approximately one hour. This feature enhances convenience, especially for users who are always on the go.

Battery Specifications

38Wh (Type A) 2 cells 7.6V 38Wh (~5000mAh) –
45Wh (Type B) 3 cells 11.1V 45Wh (~4054mAh) 5B10W13961, 5B10W67193, etc.

Both battery types are designed to effectively power your laptop while ensuring optimal performance and longevity.

Battery Life Expectations

Lenovo’s testing provides the following insights into the battery life for both variants:

  • 38Wh: Approximately 5.5 hours (MobileMark 2018); up to 8.5 hours during local 1080p video playback at 150 nits.
  • 45Wh: Approximately 7.5 hours (MobileMark 2018); up to 12 hours during local video playback.

Physical Characteristics and Replacement Process

Both the 38Wh and 45Wh batteries are integrated and require the bottom cover to be removed for replacement, which can be straightforward with the right tools. A detailed tutorial on this process is available on YouTube.

Compatibility and Part Numbers

When looking for a replacement, it’s crucial to ensure compatibility. The IdeaPad 3 15ITL6 and Slim 3 15ITL6 are often used interchangeably regarding the chassis and battery configuration. Here are some key considerations:

  • Internal Battery Part Numbers: Common options for the 45Wh variant include 5B10W13961 and 5B10W67193.
  • Sub-model Compatibility: The design is shared across different regional sub-models, such as 82H8.

Symptoms of Battery Failure

As your laptop battery ages, you may notice several symptoms that indicate a need for replacement:

  • Unexpected Shutdowns: If your laptop turns off suddenly despite showing a charge, it’s a sign the battery might be failing.
  • Overheating: Excessive heat during charging or use can indicate battery issues.
  • Charging Problems: If the battery struggles to charge or the charging indicator does not light up, it may need replacing.
  • Decreased Battery Life: An overly rapid drop in battery life is a clear indication of wear and tear.

Replacement and Upgrade Guidance

If you’re considering a battery swap, you have two main options:

  1. Replace with the Same Variant: If your laptop originally came with a 38Wh battery, you can replace it with another 38Wh type.
  2. Upgrade to a Higher Capacity: Users can upgrade from a 38Wh to a 45Wh battery, given that the physical dimensions and connectors are compatible.

Here are the steps to replace your Lenovo IdeaPad Slim 3 15ITL6 battery:

  1. Power Down and Unplug: Ensure the laptop is completely turned off and disconnected from any power source.
  2. Remove Screws: Take out all screws from the bottom cover of the laptop.
  3. Pry Open the Cover: Use a plastic pry tool to carefully work around the seam and release the clips holding the bottom cover in place.
  4. Disconnect the Old Battery: Detach the existing battery from the motherboard by its cable.
  5. Install the New Battery: Attach the replacement battery, ensuring it’s secured, and reconnect its cable.
  6. Reassemble: Replace the bottom cover and screws.

Warranty and Purchasing Options

When it comes to purchasing a replacement battery, consider the following:

  • Warranty: A one-year warranty is standard for most reputable replacement batteries. Certain OEM/Lenovo-supplied batteries may offer even longer coverage.
  • Pricing: Genuine/OEM batteries typically range from $60 to $90 USD, depending on the supplier. Aftermarket options can be lower but may compromise quality and longevity.
  • Authenticity Checks: Always look for batteries marked with Lenovo FRU/part numbers. Authentic products will include quality certifications marked on the label.

Purchasing from established retailers is always advisable to avoid potential quality and compatibility issues.

User Experiences and Tips

  • Battery Endurance: Users generally find satisfactory battery life, with real-world use suggesting that the 45Wh variation can yield around 5 to 8 hours depending on tasks and settings.
  • Reputable Retailers: Always opt to buy from trusted retailers to ensure product quality and compatibility.
  • Utilize Video Guides: Many users have found success following video instructions for disassembly and battery replacement.

Important Considerations

  • Expected Longevity: Under normal usage conditions, laptop batteries typically last around 2-3 years. Regular deep discharges, high temperatures, and heavy use can significantly shorten this lifespan.
  • Correct Specifications: Always confirm the voltage and cell count when searching for a replacement battery. Mixing incompatible batteries can damage your device or create charging problems.

Conclusion

In summary, the Lenovo IdeaPad Slim 3 15ITL6 supports both a 38Wh and a 45Wh integrated battery, with the latter offering enhanced performance and longevity. Replacements are user-serviceable, and it’s essential to source them from reputable suppliers to ensure warranty and quality.
