BU-703: Health Concerns with Batteries

Become familiar with the do's and don’ts when handling batteries.

Batteries are safe, but caution is necessary when touching damaged cells and when handling lead acid systems that have access to lead and sulfuric acid. Several countries label lead acid as hazardous material, and rightly so. Lead can be a health hazard if not properly handled.


Lead is a toxic metal that can enter the body by inhalation of lead dust or ingestion when touching the mouth with lead-contaminated hands. If leaked onto the ground, acid and lead particles contaminate the soil and become airborne when dry. Children and fetuses of pregnant women are most vulnerable to lead exposure because their bodies are developing. Excessive levels of lead can affect a child’s growth, cause brain damage, harm kidneys, impair hearing and induce behavioral problems. In adults, lead can cause memory loss and lower the ability to concentrate, as well as harm the reproductive system. Lead is also known to cause high blood pressure, nerve disorders, and muscle and joint pain. Researchers speculate that Ludwig van Beethoven became ill and died because of lead poisoning. 

By 2017, members of the International Lead Association (ILA) want to keep the lead blood level of workers in mining, smelting, refining and recycling below 30 micrograms per deciliter (30µg/dl). In 2014, the average participating employee checked in at 15.6µg/dl, but 4.8 percent were above 30µg/dl. (Source Batteries & Energy Storage Technology, Summer 2015.)

Lead occurs naturally in soil at 15–40mg/kg level. This level can increase multi-fold near lead battery manufacturing and recycling plants. Soil levels in developing countries, including on the continent of Africa, recorded lead contamination levels of 40–140,000mg/kg. (See BU-705: How to Recycle Batteries.)

Sulfuric Acid

The sulfuric acid in a lead acid battery is highly corrosive and is more harmful than acids used in most other battery systems. Contact with eye can cause permanent blindness; swallowing damages internal organs that can lead to death. First aid treatment calls for flushing the skin for 10–15 minutes with large amounts of water to cool the affected tissue and to prevent secondary damage. Immediately remove contaminated clothing and thoroughly wash the underlying skin. Always wear protective equipment when handling sulfuric acid.


Cadmium used in nickel-cadmium batteries is considered more harmful than lead if ingested. Workers at NiCd manufacturing plants in Japan have been experiencing health problems from prolonged exposure to the metal, and governments have banned disposal of nickel-cadmium batteries in landfills. The soft, whitish metal that occurs naturally in the soil can damage kidneys. Cadmium can be absorbed through the skin by touching a spilled battery. Since most NiCd batteries are sealed, there are no health risks in handling intact cells; caution is required when working with an open battery.

Nickel-metal-hydride is considered non-toxic and the only concern is the electrolyte. Although toxic to plants, nickel is not harmful to humans.

Lithium-ion is also benign — the battery contains little toxic material. Nevertheless, caution is required when working with a damaged battery. When handling a spilled battery, do not touch your mouth, nose or eyes. Wash your hands thoroughly.

Keep small batteries out of children’s reach. Children younger than four are the most likely to swallow batteries, and the most common types that are ingested are button cells. Each year in the United States alone, more than 2,800 children are treated in emergency rooms for swallowing button batteries. According to a 2015 report, serious injuries and deaths from swallowing batteries have increased nine-fold in the last decade.

The battery often gets stuck in the esophagus (the tube that passes food). Water or saliva creates an electrical current that can trigger a chemical reaction producing hydroxide, a caustic ion that causes serious burns to the surrounding tissue. Doctors often misdiagnose the symptoms, which can reveal themselves as fever, vomiting, poor appetite and weariness. Batteries that make it through the esophagus often move through the digestive tract with little or no lasting damage. The advice to a parent is to choose safe toys and to keep small batteries away from young children.

Safety Tips


Charging batteries in living quarters should be safe, and this also applies to lead acid. Ventilate the area regularly as you would a kitchen when cooking. Lead acid produces some hydrogen gas but the amount is minimal when charged correctly. Hydrogen gas becomes explosive at a concentration of 4 percent. This would only be achieved if large lead acid batteries were charged in a sealed room.

Over-charging a lead acid battery can produce hydrogen sulfide. The gas is colorless, very poisonous, flammable and has the odor of rotten eggs. Hydrogen sulfide also occurs naturally during the breakdown of organic matter in swamps and sewers; it is present in volcanic gases, natural gas and some well waters. Being heavier than air, the gas accumulates at the bottom of poorly ventilated spaces. Although noticeable at first, the sense of smell deadens the sensation with time and potential victims may be unaware of its presence.

As a simple guideline, hydrogen sulfide becomes harmful to human life if the odor is noticeable. Turn off the charger, vent the facility and stay outside until the odor disappears.

Caution: When charging an SLA with over-voltage, current limiting must be applied to protect the battery. Always set the current limit to the lowest practical setting and observe the battery voltage and temperature during charge. In case of rupture, leaking electrolyte or any other cause of exposure to the electrolyte, flush with water immediately. If eye exposure occurs, flush with water for 15 minutes and consult a physician immediately. Wear approved gloves when touching electrolyte, lead and cadmium. On exposure to skin, flush with water immediately.

I purchased a Turnigy 25-35 discharge 1300mAh 6 cell months ago. Had need for it tried charging got error message not connected checked and found a tab that entered the end cell (+) had pulled out from the top of a flat cell where the tab entered the aluminum foil cell-pack. Out of warranty so my thought was to split the front fold & the rear foil so I could solder the broken tab back together. But I can’ t separate the top seam.  Next step i thought I would seek help.  Should I open the foil pack on top at the broken tap I would then be inside the cell package. and re-attach a tab or wire to inside the foil package. This would expose the guts to air & seal it back with glue (silicone, epoxy… duct tape and glue. Thank you Brooks

Dear Jaz,
    To my knowledge, as long as the battery was intact after the washing and drying, there should be no problem wearing your clothes.
    However, to be absolutely sure and to further ease your mind, I would suggest calling the toll-free number for the battery company and ask them for their feedback about your situation.
    I hope this information is useful to you.

Hello i am a delivery driver for an auto business and i too have been feeling these symptoms of fatigue appetite loss headaches vision loss and other internal organ pain. There needs to be more enforcement on regulations and teachings of how to keep these safe and out of the wrong hands. A lot of the products we use are manufactured with products from sources all around the world like china america and who knows where else. I just really think its time we step up safety at home as well as the work place. I am seeing effects because of my cellphone i carry in my pocket damn near all the time. I feel a cellphone vibration in my pocket sometimes when my phone isnt even on me. We need more regulations on these batteries and electronics. I hope this can be helpful in any way possible to others. Ciao for now

Dora,    As long as the batteries are in good condition i.e. not overheating or leaking they are not a problem. I would be more concerned about the r f and its radiation that your device uses/creates to communicate. As with mobile phones the advice is to keep it away from your body in loose fitting clothing and don’t keep it in the same place all the time. Having said that, here am I using the same wi fi system to send this. Don’t worry, worrying will do you more harm.

Christy. A cold water wash for a long period (20 mins +) is.what should be done immediately after exposure as an interim measure then see a medic. Go see a doctor, the faster the better. Ps Any one with more medical knowledge than me, reading this please post if I am wrong about the water i.e. battery chemical compositions that should not be washed away with water.

Hi, one major issue is that more complex electronics such as phones, hard disk drives and other items can be damaged because the surface mount components such as crystals and resistors are corroded over time. Despite manufacturer claims this is not something usually considered in a MTTF/MTBF so failure can occur with little or no warning on multiple devices which can be a serious problem in a data centre with multiple lead acid equipped UPS’s.
Bacteria from handling can grow on the drive and emit H2S which then corrodes the parts, so this is another potential cause of failure.

I recently dined at a large chain resteraunt and was eating a fried appetizer with my family. At the bottom we found a fried AAA Duracell battery. We went straight to hospital and are all now safe at home and healthy for now. What could this do to someone long term in your opinion? Does anyone have an idea of what chemicals are released from the battery and into food with it in the fryer? I have googled to look for answers, but this seems to not have happened to many people. I’m worried about cancer years down the road.
