October 3, 2026 — An incident report details that Kirkland brand AAA batteries, manufactured by Costco Wholesale, allegedly overheated in two separate devices, melting their outer sleeves and causing a burn injury to a 9-year-old child. The incident highlights potential thermal hazards associated with the popular consumer batteries.
Product Details
Incident Overview
On September 14, 2026, an incident was reported involving Kirkland brand AAA batteries. According to the report, two different Kirkland AAA batteries, each placed in separate electronic devices, exhibited severe overheating. The outer sleeve of both batteries became extremely hot and began to melt. A 9-year-old child, upon noticing a remote control wasn’t working, touched one of the overheated batteries and sustained a burn injury. The report explicitly states that this occurred with two distinct batteries in two separate devices, underscoring a potentially systemic issue rather than an isolated malfunction in a single instance. The specific retailer where the batteries were purchased was not specified in the incident report.
Safety Concerns
The reported incident with Kirkland AAA batteries raises significant safety concerns regarding the potential for overheating and thermal hazards:
- Immediate Dangers: The primary immediate danger is thermal burns, as experienced by the 9-year-old child in this report. Overheating batteries can reach temperatures high enough to cause painful and potentially severe skin burns upon contact.
- Long-term risks: While not reported in this specific incident, extreme overheating and melting can, in some cases, escalate to a fire hazard, especially if the batteries are in contact with flammable materials or if the internal components are compromised. The intense heat generated can also cause significant damage to the electronic devices in which the batteries are housed, potentially rendering them inoperable or creating further safety risks.
- Who Might Be Affected: Children are particularly vulnerable to such incidents, as they may not immediately recognize the danger of an overheated battery. Adults handling these batteries are also at risk. The widespread use of AAA batteries in common household devices means a large segment of the population could potentially be affected.
- Property damage potential: Beyond personal injury, overheating batteries can damage the electronic devices they power, leading to financial loss for consumers.
What Consumers Should Do
If you own Kirkland AAA batteries, particularly those that may have been purchased around the time of this incident, it is crucial to take the following precautions:
- Immediate Steps: If you notice any battery feeling excessively hot, swelling, leaking, or showing signs of melting, immediately and carefully remove it from the device, avoiding direct skin contact if possible. Place it on a non-flammable surface away from any combustibles.
- Check Your Batteries: Periodically inspect your Kirkland AAA batteries in use for any signs of physical damage, overheating, or unusual behavior. Do not ignore a device that feels unusually warm.
- Safe Handling and Storage: Store batteries in a cool, dry place and keep them in their original packaging until ready for use. Avoid mixing old and new batteries, or different types of batteries, in the same device.
- Reporting Procedures: If you experience a similar incident or have concerns about your Kirkland AAA batteries, report it immediately to the U.S. Consumer Product Safety Commission (CPSC) at SaferProducts.gov. You should also consider contacting Costco Wholesale directly to report the issue.
