The phone that falls away safely tucked away in your shirt pocket falls out and sadly falls in a sink full of water. You frantically retrieve it, but it’s full of water. You dry it up and find that somehow it still works. It’s a miracle. You acted nimbly to rescue your phone and didn’t need a bag of rice. In this guide, I will discuss how to save electronics damaged by batteries.

All is well on the planet of probable water damage to electronic gadgets. After two days, you realize that your smartphone at the moment doesn’t work, managed to short circuit. Your miracle turned into a nightmare. To evade this, we approach you How to Save Electronics Damaged by Batteries.

If this situation happens, you will notice that the battery compartment will be very deplorable. On the other hand, there are options to rescue it. You have nothing to lose.

If you Google “flash battery corrosion cleaner,” you will find numerous threads in one that recommends using baking soda to remove corrosion, which may not be the best thing for alkaline batteries. The white powder is nothing more than a base, so you will need acid to remove it. This is where vinegar comes into play.

Lithium-ion batteries are used with more excellent continuity in cell phones based on reversible chemistry.

The chemical processes have the possibility of leaking, although these events are infrequent. Even if the chemicals do leak, they are less likely to react with electronics than other types of batteries.

On the other hand, in rare events, leaking lithium batteries can cause detonations and are dangerous.

How to Rescue Electronic Gadgets Damaged by Batteries

Materials needed:

  • Safety items (rubber gloves, mask, eye protection).
  • Cotton swabs
  • White vinegar
  • Pencil eraser

Step 1: with the rubber gloves on, remove the batteries from the device.

First of all, make sure the safety. After a water-related inconvenience, cleaning a gadget is always a great choice. Remember to remove the power points, batteries, or some power source first.

In addition to avoiding damage, it also avoids any short circuits in the gadget. By doing this, you will also expose complementary connectors that already have the potential to be corrupted, so use caution.

Watch out for signs of water damage. Makers have positioned a warning about liquid damage inside phones next to the battery.

It often has a clear or scratched pattern; if it has a solid hue, it probably has water damage.

To prevent a catastrophe, leaky batteries must be properly removed and disposed of. Potassium hydroxide is what makes up the white powder in alkaline batteries. Work in an area with good ventilation or while wearing a respirator for further safety.

Step 2: Dip a cotton swab (or toothbrush) in vinegar and blot the excess.

Use cotton swabs and a cleaning satisfaction such as isopropyl alcohol, baking soda, water, or even vinegar to clean it.

Gently place the satisfaction on the affected sector and wipe back and forth until the corrosion is removed. If required, leave some of the delights on the corroded area and wipe it off afterward.

Dry your electronic device with a cloth slowly or a hairdryer in a cool space; do not use heat to dry your gadget.

Make sure your gadget is dry before attempting to replace the battery and turn the device on. Any water on the gadget could cause additional water damage.

The unit can turn on but not act 100% usually. Odds are there is still some water inside the unit.

The last effort is to disassemble the unit. This is only suggested for basic mobiles and only if you feel 100% practical disassembling the gadget.

Keep in mind that opening the unit invalidates any warranty that may exist. Keep a careful record of where all parts go while disassembling.

It is only recommended for basic phones and only if you feel 100% comfortable disassembling the device.

Completely disassemble your gadget by pulling out all the cables, opening all the connectors, and pulling out the shields to get underneath them.

Step 3: Use a pencil eraser to remove the corrosion.

You can use a rubber eraser to remove the corrosion at the root, but be very careful with this.

Step 4: Put the new batteries correctly into the device and turn it on.

If your device is not damaged enough by alkaline battery corrosion, this procedure should also work for you.

Concept of Corrosion and its Causes

Corrosion has always been the hidden and most puzzling cause of water damage. The breakdown is the gradual degradation of a material, usually a metal, by chemical opposition to its environment.

The most common corrosion occurs when metal combines with water and oxygen, creating iron oxide. This opposition occurs when combining these elements over a prolonged period.

Does Corrosion Ruin Electronics?

There is no specific time when the damage can be noticed; an electronic device may begin to rust within hours of the initial water damage event or remain unaffected for days before exhibiting warnings of damage.

The effectiveness with which it is installed depends on the humidity scenarios. The severity of the water damage, how long the device has been submerged, and its manufacture.

If the device was manufactured to avoid water damage, exposing it to water will not affect it.

All of these components significantly affect the time frame considered for a water-damaged device.

Remember that whenever a water-damaged device is attempted, there is no way to guarantee its recovery once you have water damage.

There are some steps to a successful repair.

When it comes to cleaning corroded electronics after water damage, you should be quite cautious.

In addition to further damaging the device, if you don’t know what you are doing, you will likely injure yourself.

Remember this: devices and liquid usually do not intermingle, so whenever you place any of these cleaning battery terminals on a device, you should use caution. The average customer should never attempt to reset a device without professional assistance.

What are Specific Warnings for the Safe Handling Lithium-Ion Batteries?

Improper handling can damage the batteries, which may result in overheating, fires, or detonation.


  • Remove batteries from gadgets that will not be used for an extended period.
  • Keep batteries away from electromagnetic sources.
  • Keep batteries intact
  • Isolate batteries that show signs of inconvenience.


  • Allow to drop or crush the battery pack.
  • Use batteries that are bulging, dented, swollen, leaking, or damaged in any way.
  • Puncture battery cases
  • Modify the battery in any way

How do I clean up a Spill of Lithium-ion Batteries?

If electrolyte from a damaged Lithium-ion battery spills from a battery pack, it can pose hazards to everyone in the industry and all responders.

Use the following precautions and methods to clean up a lithium-ion spill:

  • Isolate and ventilate the area.
  • Wear proper PPE (goggles, gloves, apron, etc.).
  • Keep a proper fire extinguisher within reach.
  • Pack the battery in a plastic bag, then place the bag in a container with sand or other chemically inert cushioning material such as vermiculite.
  • Use inert, non-cellulose absorbents to clean up the spilled electrolyte.
  • Place used absorbents and personal custody kit in a sealed bag and contacted your environmental or shipping official for proper disposal of the corroded battery and absorbents.
  • Do not put used batteries and absorbents in regular trash or recycling garbage cans.
  • Most battery manufacturers suggest storing lithium battery packs at 40 percent battery level and away from the gadget in which they are used.
  • This facilitates some self-discharge and, simultaneously, retains enough charge to keep the custody circuit active.
  • Charging your phone throughout the night: battery myths debunked.

Charging my iPhone throughout the night will overcharge the battery: false.

The only things all professionals agree on is that smartphones are capable enough not to accept overcharging occur.

On the inside, the complementary custodial chips affirm that this will not happen in a tablet or smartphone, or laptop PC. Once the internal Lithium-ion battery hits 100 percent of its capacity, the charging stops.

That often happens in an hour or two, at the latest.

If you leave the mobile device plugged in overnight, it’s going to use a bit of energy, continually trickling new juice to the battery every time it falls to 99 percent.

That’s affecting the usable life of your phone.

How to Store Vintage Electronics

  • Remove batteries of all types.
  • Take care of plastics and avoid ultraviolet light.
  • Remove or replace capacitors.
  • Avoid water, humidity, and heat.

Mold is fundamentally complicated. It can ruin fabric, paper, label stickers, leather, vinyl, synthetic leather, plastic, or rubber surfaces, such as those seen on the plastic cable insulation of the NES AC adapter above.

When mold does establish, it isn’t easy to control, as its rough roots can remain dormant until conditions are right when the humidity exceeds 58%. The temperature also exceeds 70 degrees Fahrenheit.

Then, the fruiting bodies grow, and the mold expels into the air that lands on exposed surfaces and the period begins again.

The development effect can be exponential if left unchecked, creating a risk to human respiration, and the mold’s digestive byproducts have the potential to decompose everything they conquer probably.

Avoid this by keeping your precious electronic gadgets clean and dust-free in a cool, dry space.

It is necessary to keep them covered with paper products. To keep an eye on humidity, I use electric dehumidifiers that work year-round and combine them with a HEPA air filter to shrink airborne spores and the dust they have a chance to feed on.

While doing so, generally avoid extremes of heat and cold. Spread and shrinkage can cause plastic and metal to crack and warp or become brittle over time.

Several comments were made about this in the comments part, and at first, I also included baking soda to normalize the alkalines. Energizer “Ultimate Lithium” has a chance to be what you think. They are usually in AA and AAA sizes. They have a slightly higher voltage than alkaline batteries. However, it is not enough to be a problem in probably 99% of devices. So please, have at least 50% even though they are not rechargeable.

We’ve seen the most remarkable repair trick to wrap aluminum foil around a piece of the rubber band. The right precaution extends the usable life of the lithium-ion battery.

Limit Battery Temperature

Limiting battery temperature extremes extends the usable life of the battery, primarily by prohibiting charging below 0 °C.

Charging below 0°C supports the metal coating on the battery anode, which can short-circuit from the inside, producing heat and making the battery unbalanced and unsafe.

Most battery chargers have provisions for measuring battery temperature. This to ensure that charging does not occur at extreme temperatures.

Avoid High Charge and Discharge Currents

High charge and discharge currents reduce the life span. Some chemistry are better suited for higher currents, such as lithium-ion, manganese, and lithium-ion phosphate. High winds often put a high voltage on the battery.

Ideally, avoid intense discharges below 2V or 2.5V.

Deep discharge can damage lithium-ion batteries. A metallic coating inside the battery can cause a short circuit, rendering the battery unusable and unsafe.

Many lithium-ion batteries have custodial circuits within their battery packs. These open the battery connection if the battery voltage drops below or exceeds 4.3V if the battery exceeds predestined limits.

How to Save Electronics Damaged by Batteries: FAQs

What do you do if your car battery is leaking acid?

Is your battery leaking acid? It may be time to get a new battery for your car if it starts to leak AAA battery acid. If you feel a problem, you should probably get it checked out by a mechanic before things worsen. When you find the right battery, it’s time to install it.

Are leaking batteries dangerous?

Battery leakage (commonly popular as battery acid) is a nasty, corrosive thing: it can burn your skin, contaminate the ground, and certainly ruin any gadget it has leaked into. With household batteries, this “acid” is alkaline by way of the chemical structure of potassium hydroxide.

What does it mean if a battery is leaking?

Batteries have within them heavy materials such as mercury, cadmium, nickel, or lithium. With them, a chemical opposition is achieved that creates the energy that makes it easier for the devices to work. But suppose the battery has been in use for a long time. 

In that case, these substances have the possibility of oxidizing and cracking even the container that stores them, i.e., the metal structure of our battery. Thus, sometimes we discover that a suspicious liquid is leaking from our batteries.

If that happens, be careful. We are talking about toxic substances, and the most important thing is to wash the hands as soon as possible.

Besides, it is advisable to take the battery out of the electronic. If we leave it there, that same liquid will attack the metallic parts that it is, more than anything, the locations where the battery makes contact, which can be unusable by the corrosion.

Batteries can start leaking while being used and discharged, making it easier for the liquid to escape from the storm.


Corrosion can be an inconvenience for quite a few people. Beyond the fact that it is ideal for changing gadgets or batteries once they expire, not everybody can acquire them instantly, and you may be in a hurry. That is why we had given you this series of steps that could assist you.
