Poisoning from a dry cell battery (including button batteries) occurs from exposure to the harmful chemicals in them.

Batteries - dry cell

• Acidic dry cell batteries
  • Manganese dioxide
  • Ammonium chloride
• Alkaline dry cell batteries
  • Sodium hydroxide
  • Potassium hydroxide

Dry cell batteries, commonly found in most households.

Note: This list may not be all-inclusive.

Symptoms vary depending on what type of battery is ingested (acidic or alkaline).

Symptoms of acidic dry cell battery poisoning include:

• Decreased mental ability
• Irritation or burns in the mouth
• Muscle cramps
• Slurred speech
• Swelling of the lower legs, ankles, or feet
• Weakness
• Nervous system
• Spastic walk
• Spasticity
• Tremor

Symptoms that can result from inhaling large amounts of the acidic battery, or contents, dust, and smoke from burning batteries include:

• Decreased mental ability
• Difficulty sleeping
• Muscle cramps
• Slurred speech
• Weakness in the legs
• Bronchitis
• Headache
• Pneumonia
• Itching skin
• Nervous system
• Numbness of the fingers or toes
• Spastic walk

Symptoms of alkaline battery poisoning may include:

• Severe pain in the mouth
• Collapse
• Inability to breathe due to the throat swelling shut
• Severe pain in the throat
• Severe abdominal pain
• Diarrhea
• Vomiting
• Drooling
• Rapid drop in blood pressure

If you suspect poisoning, seek emergency medical care immediately.

If there has been an ingestion of a button battery, DO NOT INDUCE VOMITING. The person who ingested the battery will need immediate x-rays at a medical facility to make sure the battery is not lodged in the esophagus. Most swallowed batteries that pass through the esophagus will pass in the stool without complication. However, batteries lodged in the esophagus can cause esophageal erosion, and can cause a hole in the esophagus very quickly. Immediate emergency treatment is necessary after a battery is swallowed.

If the battery was swallowed, give water or milk.

If inhaled, take the patient outdoors to fresh air.

Determine the following information:

• The patient's age, weight, and condition
• The name of the product (ingredients and strengths if known)
• The time it was swallowed
• The amount swallowed

If you are in the United States, call Poison Control at 1-800-222-1222. This national hotline number will let you talk to experts in poisoning. They will give you further instructions.

Some or all of the following procedures may be performed:

• Treatment of symptoms
• Monitoring of vital signs
• Upper GI endoscopy to retrieve a battery lodged in the esophagus

Full recovery is often possible if treated quickly. Serious problems are usually seen only following industrial accidents. Most household exposures (such as licking some liquid from a leaking battery) are minor.
