Picture of Bring your solar powered lamps back to life
Everybody has a bunch of these at home. You see them in the store, buy them, put them in your yard and depending on their quality you will be throwing them a way a few weeks to a season later.

Solar powered lamps work like this;

1. Sun shines on the solar panel. The battery gets charged.
2. Once it gets dark a photoresistor tells the LED to light up and the battery starts to discharge.

The main problem with solar powered lamps is the battery. When the lamp is brand new and the battery is fully charged it will work really well. But usually the solar panel is not enough to charge the battery fully so it will slowly get drained. A battery that is discharged loses its capacity and eventually the battery goes dead.

In this instructable I will show you how simple it is to replace the dead battery with a fresh one.

Many people don't realize how easy it is to actually do so. I am one of those who threw away solar powered lamps for more than 500$. It was just recently, when I started to work with electronics, that I decided to open one up to see if there was some component I could replace and bring it back to life. Turns out it was much easier than I thought.


Step 1: Stuff you need

Picture of Stuff you need
For this project you need the following;

- A broken solar powered lamp to fix
- A screwdriver
- A fresh rechargable NiCd battery
- 5 minutes to spare

And just my 2 cents worth, in stead of buying rechargeable solar batteries, our 99c stores sells the whole unit.

You may reuse some of those as parts!
