The Guardians of Power : Lady Battery : Experiments

📌 Experiment Goal

In this experiment, we will measure the capacity of a battery and understand how usage and degradation affect its performance.

A battery's capacity depends only on two key factors:
✅ Its technology (Li-ion, LiPo, NiMH, etc.)
✅ Its physical size (the bigger it is, the more energy it can store)

All other factors (charging cycles, temperature, usage) affect the actual efficiency of the battery and can lead to capacity loss over time.

💡 Why is this experiment useful?
It will help us evaluate a battery’s condition and determine if it is still functioning properly or if it’s deteriorating.

🚨 Safety Precautions Before We Start!

Very Important: ⚠️ Do NOT proceed if you are unsure about the safety of your battery!

✅ The battery must be in good condition – if it is swollen, torn, or visibly damaged, do NOT use it!
✅ Never charge a battery with the wrong voltage! If you apply incorrect voltage, you risk fire or explosion!
✅ Only use rechargeable batteries and certified chargers!
✅ Work in a well-ventilated area, away from flammable objects.

📜 Materials Needed

✔ USB Tester 🔌 – to measure the energy entering the battery
✔ A standard USB charger ⚡
✔ The battery you want to test 🔋
✔ A device that uses this battery 📱 (phone, power bank, flashlight, etc.)
✔ A timer or smartphone to track charging time ⏱️
✔ Experiment data recording sheet 📝 (print this before starting!)

🔹 Tip: Print the experiment sheet to easily record your data! 📄

🛠️ Steps to Perform the Experiment

1️⃣ Step 1: Fully Discharge the Battery

🔻 We completely empty the battery by using it in its device:

• If it’s a phone, play games until it shuts down 📱🔋
• If it’s a flashlight, leave it on until it goes off 🔦
• If it’s a power bank, use it until it stops charging devices

🔴 Important: Do NOT proceed unless the battery is completely discharged!

2️⃣ Step 2: Connect the USB Tester and Prepare for Measurement

✔ Connect the USB Tester to your charger ⚡
✔ Connect the discharged battery (or device) to the charger
✔ Press the RESET button on the USB Tester 🔄 to start fresh

📌 Begin recording:

• Voltage (V) ⚡
• Current (A) 🔋
• Total energy (mAh) stored in the battery

📄 Write down the data on your sheet every 15 minutes!

🎥 Extra Tip: Set up a camera to record a timelapse 🎬 to track changes in the USB Tester readings without writing everything by hand!

3️⃣ Step 3: Wait for Full Charge

🔵 Let the battery charge fully without interruptions.

⏱ Once the charger stops supplying power:
✔ The current (A) on the USB Tester will drop to 0
✔ Charging time will stop
✔ Capacity (mAh) will remain stable

📄 Write down the final battery capacity in your experiment sheet!

4️⃣ Step 4: Analyze the Results

📊 Compare your recorded data with the battery's rated capacity:

✅ If the difference is less than 10%, the battery is in good condition! 🟢
⚠️ If the difference is 10-20%, some normal degradation has occurred. 🟡
🔴 If capacity has dropped by 30% or more, the battery is in poor condition! 🔥

Example:
🔹 If a battery is rated 5000mAh and we measure 4700mAh, it’s fine!
🔹 If a battery is rated 5000mAh and we measure 3500mAh, it’s time to replace it!

Important: Repeat the experiment at least 3 times to ensure accuracy!

📌 Final Conclusion!

✔ Now you know how to measure a battery’s actual capacity! 🎯

Dangerous Experiments! 🧪🔥

🔒 WARNING! The following text contains high-risk experimental procedures that you should NOT attempt unless you EXACTLY know what you're doing! Danger Level: HIGH! 🚨

If you're here, it means you're curious about more extreme experiments and want to push the limits of batteries. I will NOT describe exactly how to do them – I will simply explain what happens if you attempt them.

🛑 1. Full Battery Discharge & Zeroing

💀 What happens?
We let the battery fully discharge, and when it drops below 10%, we short-circuit the terminals and let it hit absolute zero.

🔥 Results:

• The battery overheats and stops functioning.
• If we try to "wake it up" and recharge it, we’ll see that it has lost over 80% of its capacity!
• The chemical structure is permanently damaged, preventing it from holding a charge.

🚨 Dangers:
❌ Extreme heat – risk of fire!
❌ Increased chance of explosion!
❌ The battery will NEVER work the same again!

⚡ 2. External Battery Damage (Hammer Test)

💥 What happens?
We take a battery and smash it with a hammer to apply mechanical stress.

🔥 Results:

• If it's completely destroyed, it will never work again.
• If it still functions, its capacity drops drastically by 80% or more.
• The internal structure breaks down, and internal connections are severed.

🚨 Dangers:
❌ May explode upon impact!
❌ Could release toxic gas or chemicals!
❌ High risk of fire and destruction!

Important: If you accidentally hit a battery and notice swelling, leaking liquid, or smoke, get rid of it immediately! DO NOT attempt to recharge it!

🚀 3. Battery Overcharging – Pushing Voltage Limits!

⚡ What happens?
We use a higher-than-recommended voltage to force-charge the battery.

🔥 Results:

• The battery overheats dangerously, damaging its chemical composition.
• For the first couple of charges, it may output way more power than normal.
• After 1-2 uses, its capacity drops by 50%, and its reliability falls to 10%!

🚨 Dangers:
❌ Can explode while charging!
❌ May overheat to the point of melting!
❌ After overcharging, the battery becomes completely unstable!

💡 When Are These Techniques Used?

🔹 In racing & performance events where maximum power is needed for a few minutes (e.g., RC racing cars 🚗, drones 🚁).
🔹 When we don’t care if the battery is destroyed after 1-2 uses.
🔹 When conducting research experiments on battery limitations.

⚠️ BUT let's be real: These experiments are extremely dangerous, and there is NO valid reason to try them in a home environment!

⚠️ Final Conclusion: DON’T Try This If You Don’t Know What You’re Doing!

🎯 The experiments above are not just advanced, they are dangerous! 🔥
🎯 If you want to learn real battery management, focus on safe experimental methods! ✅
🎯 If you read this and think, "I should try this!", then STOP RIGHT NOW! 🚫
