How to check your laptop's battery health - don't buy a laptop with poor battery life!

When buying a used or refurbished laptop, one of the most critical components to check is the battery. A healthy battery ensures your laptop stays powered for longer, supports productivity and avoids unexpected shutdowns. Unfortunately, not all sellers prioritize battery health, and this has become a significant issue in Kenya, where many people face problems with used laptops that drain too quickly or fail to hold a charge.

For Windows

Method 1: Using the Battery Report Command

1. Open Command Prompt: Press Win + R, type cmd, and hit Enter.
2. Type powercfg /batteryreport and press Enter.
3. This will generate a battery report and save it as an HTML file.
4. Find the report in: C:\Users\YourUsername\battery-report.html
5. Open the file in a browser and check Design Capacity vs. Full Charge Capacity (lower full charge capacity indicates battery wear), battery cycles (most batteries last about 500-1000 cycles), and battery life estimates over time.

Method 2: Check via Windows Settings

Go to Settings (Win + I), navigate to System > Power & Battery > Battery Usage. Here, you can see battery usage trends but not full health details.

Method 3: Using Third-Party Software

If you need real-time monitoring, try HWMonitor, BatteryCare, or HWiNFO.

For Mac (macOS)

Method 1: Check via System Information

Hold the Option key and click the Apple Menu. Select System Information, then navigate to Power > Battery Information. Look at Cycle Count (higher means more wear) and Condition (Normal, Replace Soon, Replace Now).

Method 2: Using macOS Ventura & Later

Go to System Settings (Cmd + Space → search "Battery"), then click Battery Health to see condition and cycle count.

For Linux (Ubuntu & Other Distros)

Open Terminal (Ctrl + Alt + T) and type upower -i $(upower -e | grep battery). Look for State (Charging or Discharging), Energy (Design vs. Full — tells you the battery wear), and Cycle Count (if supported). Alternatively, use cat /sys/class/power_supply/BAT0/capacity to get the current battery percentage.

When to Replace Your Battery

• If full charge capacity is less than 50% of the design capacity.
• If cycle count is above 800-1000 for most laptops.
• If it drains too fast or doesn't hold a charge.
