Your old laptop batteries may have found some new usefulness. Some Do It Yourself (DIY) enthusiasts who can’t afford commercially produced power-walls are using recycled batteries to build their own.

 

These power-wall are used to provide a convenient way for homeowners to store electricity for future use, such as when the power goes out. Tesla’s Powerwall is one of the leading brands in the market, however DIY enthusiasts have constructed their own powerwalls by utilizing old, recycled batteries from laptops.

These DIY are capitalizing on their own resourcefulness and the wastefulness of those around them. 18650 lithium-ion batteries are the most recommended batteries to use, and they’re easily identifiable by their colorful plastic. They can be found in more than just laptops.

Why would you want a battery for your house? House batteries will let you be more power independent. If you have solar panels or electricity generated from wind, they don’t always produce the same amount of power. With a battery, you can store this energy during the day (or during wind) and then use it at night.

Can this battery run your house? Actually, no. Your house runs on AC current but the battery gives you DC current. This means that you need to take the DC current and convert it to AC current. You might have a device that does this in your car so that you can plug in household items like a computer or a coffee pot.
