6 Steps On How To Repair Your Power Bank Battery – DIY
I will show you how to repair such power banks that are not charging.
The batteries inside the power bank was corroded, so i tried to remove them out and gave a new life. I will share some simple tips in order to how to remove such corrosion even with home made solution easily available in our Kitchen. You can also replace new batteries for full capacity of power bank.
Portable Power Banks are comprised of a special battery in a special case with a special circuit to control power flow. They allow you to store electrical energy (deposit it in the bank) and then later use it to charge up a mobile device (withdraw it from the bank).
Power Banks have become increasingly popular as the battery life of our beloved phones, tablets and portable media players is outstripped by the amount of time we spend using them each day. By keeping a battery backup close by, you can top-up your devices while far from a wall outlet.
The Power Banks we’re talking about are good for almost any USB-charged devices. Cameras, Portable speakers, GPS systems, MP3 players, Smartphones and even some tablets can be charged from a power bank, practically anything that charges from USB at home can be charged from a power bank but you just have to remember to keep your power bank charged. Power Banks may also be known as power stations or battery banks too.
Steps To Follow
Step 1: Disassembly
First disassemble the power Bank carefully.
You need to apply little bit of force but be carefull not to break the circuit board inside. Do not forget to take safety precautions.
Step 2: Checking for Problems and Errors
Here observing carefully in my case i found corrosion/rust over all my individual Li-ion battery . So in order to remove this use white vinegar and rub over the surface where corrosion/rust is present. This will clean the contact surfaces of the battery and now we are ready to solder all batteries together.
If you don’t have White vinegar the you can do it via making your own solution.
Follow these steps in making repairs:
This process uses two solutions, one is regular table salt and vinegar. Any kind of vinegar will fine here. Its the acidity and corrosiveness of the salt and vinegar together that you want. The other solution is Sodium Bicarbonate/baking soda, and water. This is used to neutralize the corrosive properties of the other solution, and to further clean the battery terminals.
Step 1: Take off the Batteries.
Step 2: Get 2 containers, one for each solution.
Step 3: Get 1 tablespoon of raw salt, and put it in one of the container. Fill up the rest of the container with vinegar, and stir the both together. Generally we put as much salt in the vinegar as will dissolve.
Step 4: Get 1 tablespoon of Sodium Bicarbonate (baking soda) and add it to the other container. Fill up the rest with water, and stir well.
Add more baking soda to make it cloudy. The amount is not important, as long as it is alkaline to cancel the acid of the vinegar solution.
Step 5: Take the cotton ball or any cloth piece and rub over the battery terminal.
Step 6: After 2 minutes or so, the terminal will look very shiny and new after appplying the vinegar solution. The acid and salt in the solution is etching away the oxides, exposing the bare metal. Make sure the metal is uniformly shiny. Leave it in longer if it is not perfectly clean throughout.
Once you are done, the shiny battery terminals are ready for soldering.
Remember, you shoud have a good knowledge of soldering.
