Stop Buying Cells: Make Any LED Candle Rechargeable

Don't throw away your old Diwali tea lights when the button batteries die! In this video, I'll show you how to salvage dead plastic tea lights and upcycle them into a long-lasting, rechargeable DC electronic candle light. Instead of replacing single-use coin cells every season, we convert the housing using a standard multi-color RGB LED, a current-limiting resistor, and a rechargeable 3.7V 18650 lithium battery. It's a simple, budget-friendly DIY fix that keeps your home lit up for hours without extra waste.
