2. Buy an OEM battery (made by your laptop maker) or a good third-party one

• Good options include: Geek Squad, uBreakiFix, or Apple Store

OEM vs. Third-Party Batteries

OEM (Original Equipment Manufacturer)

• Cons: Cost 2-3 times more (often $80-$150)

Third-Party

• Pros: Much cheaper ($30-$80), sometimes higher capacity
• Cons: May not last as long, potential safety risks
  If you have a work laptop or expensive model, stick with OEM batteries like those for high-performance Lenovo ThinkPads.

Environmental Impact

Replacing your battery instead of buying a new laptop:

• Keeps 15kg of e-waste out of landfills
• Reduces the need for lithium mining
• Saves resources needed to make a whole new device
  Many stores like Best Buy and Staples will recycle your old battery for free. Some even offer $10-$50 gift cards for recycling.

Battery Maintenance Tips

To make your new battery last longer:

• Keep your laptop cool (heat kills batteries)
• Avoid letting it drop to 0% or stay at 100% for long times
• Update your power management settings

• Use battery calibration software occasionally
