Has your camera ever run out of battery when it was needed most? It’s annoying when electronic devices run out of battery in an emergency situation because we don’t always carry chargers with us. For those who enjoy (or need to) improvise, the following tips can be extremely helpful.
Steps
Use rechargeable batteries for batteries

Remove the battery from the device. You will need to work with the battery contacts. Some phones use non-removable batteries, so it’s important to know your phone well. For most (not all) Android and Windows phones, the back cover can be removed when you apply moderate force to the correct position. However, you should not attempt to do so with an Apple product.

Find some AA, AAA, or 9V batteries. Other than the power transmitted from a wall outlet (alternating current), the energy in common household batteries is the same as that used in cell phones or digital cameras. [1] X Research Source
- You might be surprised why you need to use one battery to charge another. You may also have expected that we will introduce some magic tricks for you to charge your battery without having to find an alternative power source. In fact, that is not possible. One of the fundamental principles of Physics (law of conservation of energy/law of conservation of mass) states that everything has its own value. [2] X Trusted Source Princeton University Go to the source Practice accepting this.
- We also recommend that you charge the battery instead of trying to ignite your electronics and use replacement batteries directly. Using the wrong amperage or voltage can potentially damage the complex circuitry inside the device, so it’s clear that these options aren’t worth the risk.

Determine the positive and negative poles of each battery. For AA batteries and other household batteries, each end will be marked. With most phone batteries, the anode is the closest to the edge, and the cathode is usually the furthest from the edge (if there are three or four connectors, one or two in the middle is usually used to regulate temperature. and other functions).

The voltage of the source battery (AA, AAA or others with sufficient power to supply) must match the battery to be charged. Nowadays, ordinary phone batteries need DC current above 3.7V to charge. So multiple AA or AAA batteries or a 9V battery would be ideal as a power source. Remember that each ordinary AA or AAA battery that we still use in our homes provides 1.5V power. In short, if you only have AA or AAA batteries in your hand and you need a power source above 3.7V, connect 3 primary batteries in series (1.5V + 1.5V + 1.5V = 4.5V).

Prepare two wires. It is best that the wire is covered with insulating plastic but leaves both ends open.
Stick or clip the power cord connecting the battery to the battery to be charged. The power cord can get hot (but only if you do it incorrectly). This process takes quite a while, so you don’t have to keep them all the time.
- If using primary AA and AAA batteries; you need to “parallel” the source batteries with the battery to be charged. This means that we will use the wire to connect the negative terminal of all the small batteries to the negative terminal of the battery to be charged, the positive pole is the same. [3] X Research Sources
After a while, the battery will be charged. You should keep in mind that the battery is only sufficiently charged for you to “fire” but cannot be fully charged.
Use rubbing tips
Remove the battery from the electronic device and hold it in the palm of your hand.
Use both hands to rub the battery vigorously to create enough friction to generate heat. Continue doing this for 30 seconds to several minutes.
- Note: Your battery is not actually recharged. Some comments online suggest that rubbing the battery will provide it with additional power, possibly from built-up static electricity. [4] X Research Source[5] X Research Source In fact, this interpretation is completely incorrect.
- Li-ion batteries, like other pure batteries, use a chemical reaction to release energy. As predicted by the Arrhenius equation, these reactions will become stronger with increasing temperature. [6] X Research Source[7] X Research Source Basically, you are boosting the conductivity of the battery by heating it up.
Insert the battery back into the electronic device. Battery life is very limited at this time, so you should take advantage of it.
Warning
- Make sure you power off the device before removing the battery so as not to change its settings.
- You should only attempt to charge rechargeable batteries. Never attempt to charge alkaline batteries or other disposable batteries.
- Do not overcharge the battery. Li-ion batteries have the potential to explode if overcharged.
