If you manage a fleet of ICU Medical or Hospira infusion pumps, you know the Plum 360 and Plum A+ are workhorses.
They are everywhere.
But their reliability depends entirely on the 6V 4.5Ah Sealed Lead Acid (SLA) battery inside. Last year, this critical component came under intense scrutiny from the FDA, leading to multiple Class I recalls—the most serious classification, reserved for situations that could cause serious injury or death.
This isn't just another maintenance bulletin. It's an urgent call to action for biomedical technicians, clinical engineers, and hospital managers. A manufacturing defect in some replacement batteries has led to diminished battery life, causing pumps to shut down unexpectedly during patient care. Compounding the issue, counterfeit batteries have also entered the supply chain, creating a perfect storm of risk. This guide cuts through the noise to give you the actionable information you need to navigate the recalls, protect your patients, and manage your pump fleet effectively.
The Heart of the Matter: A 6V Sealed Lead Acid Battery
Unlike the more modern NiMH batteries found in some medical equipment, the Plum 360 pump uses a traditional 6V 4.5Ah Sealed Lead Acid battery. This is the tried-and-true battery technology that has powered critical medical devices for decades. Its reliability and low cost make it a staple in hospitals worldwide.
Why SLA Remains a Standard
SLA batteries are known for their simple, robust charging requirements and proven safety record. They provide a stable power source that is predictable and easy to manage. For a high-volume device like the Plum 360, the low cost of SLA technology is a major advantage. At just $25, a quality replacement like the RD Batteries SKU 6579 makes it affordable for hospitals to maintain a healthy stock of spares and perform proactive replacements without breaking the budget.
This battery is a direct replacement for OEM part numbers 840-95066-002, 840-95066-003, 840-95066-404, SUB0000864, SUB0000594, and SUB0001420. It fits both the Hospira and ICU Medical branded Plum A+ and Plum 360 infusion pumps, simplifying your inventory no matter which models are in your fleet.
The FDA Class I Recall: What You Need to Know
In May 2023, the FDA issued a Class I recall for 1,904 replacement batteries distributed between February 2022 and December 2022. A manufacturing defect was found to substantially diminish battery life, leading to hundreds of complaints and at least one adverse event identified by the FDA. The core issue is that pumps running on these defective batteries can shut down prematurely, interrupting the delivery of critical medications.
How to Identify and Respond to the Recall
The recall affects specific battery list numbers: SUB0000864 for the Plum 360 and SUB0000594 for the Plum A+ and A+3. The FDA issued a clear recommendation for all clinical users and biomedical engineering departments. Your first step is to identify all potentially affected batteries in your inventory and in service.
For clinical staff, the guidance was similarly clear.
You should keep the pump plugged into AC power whenever possible.
Before transporting a patient, you must ensure the battery is fully charged. You also need to have a backup pump available during all infusions, especially for life-sustaining medications. If a pump displays a Replace Battery alarm, you must switch to a different pump immediately and take the original pump out of service.
For biomedical departments, the responsibility is to manage the recall process. You need to ensure all users are aware of the risks. You must also replace the affected batteries. ICU Medical has committed to replacing all affected batteries, but in the interim, you may use new, non-recalled batteries. Critically, the FDA warns not to use any replacement battery that shows signs of corroded terminals.
The Counterfeit Battery Problem
To make matters worse, a second Class I recall was issued in December 2024 for counterfeit CSB batteries intended for these same pumps. These unauthorized batteries were found to fail prematurely and are not validated for use in Plum infusion systems. This highlights the importance of sourcing replacement batteries from trusted, reputable suppliers who can guarantee authenticity and quality.
SLA Battery Maintenance: 4 Keys to Longevity
Sealed Lead Acid batteries have different maintenance needs than their NiMH counterparts. Proper care is essential to maximize their lifespan and ensure they are ready when called upon.
Charging and Discharging
SLA batteries perform best when kept at or near a full charge.
Unlike NiMH batteries that benefit from occasional cycling, you should avoid deep discharging an SLA battery. The best practice is to keep your Plum 360 pumps plugged into AC power as much as possible. This “float charging” keeps the battery topped off and ready for immediate use without causing damage.
Temperature Control
Extreme temperatures are the enemy of SLA batteries. High heat can cause the battery to off-gas and can permanently reduce its capacity. Cold temperatures, on the other hand, reduce the battery’s available power. You should store and operate your infusion pumps in climate-controlled environments whenever possible. Avoid leaving pumps in hot storage rooms or near windows with direct sunlight.
Cleaning and Corrosion Prevention
Corrosion on the battery terminals was a specific concern raised in the FDA recall notices. This is often caused by improper cleaning where fluid seeps into the battery compartment. You must use only manufacturer-approved cleaning agents and ensure no liquid enters the pump housing. Periodically inspect the battery terminals and connectors. If you see any signs of white, powdery buildup, clean it off immediately with a terminal cleaning brush. A clean connection is essential for proper charging and reliable power delivery.
Regular Testing
Even with perfect maintenance, SLA batteries have a finite lifespan, typically around 2-3 years in a hospital setting. You should implement a program of regular load testing to identify batteries that are nearing the end of their life. A load test measures the battery’s ability to deliver power under real-world conditions. Any battery that fails a load test or shows a significant drop in capacity should be replaced proactively, even if it hasn’t triggered a “Replace Battery” alarm yet.
Proactive Replacement: A Cost-Effective Strategy
The aforementioned recalls underscore the importance of a proactive battery replacement program. Waiting for a battery to fail before replacing it is a reactive strategy that introduces unnecessary risk and cost. A proactive approach, where batteries are replaced on a set schedule, is far safer and more cost-effective in the long run.
The ROI of Preventive Maintenance
Consider the costs.
A quality replacement battery for a Plum 360 is incredibly affordable at under $30. The cost of an unexpected pump failure is not.
When a pump goes down during a critical infusion, the indirect costs—from patient risk to staff time spent managing the crisis—are immense. A scheduled replacement program turns an unpredictable emergency into a predictable, manageable line item in your budget.
For example, by replacing batteries every two years, you can virtually eliminate unexpected battery failures from your list of worries. This allows for predictable budgeting, bulk purchasing to secure better pricing, and reduced labor costs by batching replacements. The return on investment is measured in enhanced patient safety, improved equipment reliability, and a more efficient workflow for your biomedical team.
Your Next Steps: Building a Reliable Battery Program
The situation with the ICU Medical Plum 360 batteries served as a powerful reminder that even the most common components can have a huge impact on patient care. The combination of a manufacturing defect recall and a counterfeit battery warning demands a rigorous response from every healthcare facility.
Building Your Action Plan
Your immediate priority is to address the FDA recalls. Identify and replace any affected or counterfeit batteries in your fleet. Your long-term strategy should be to implement a robust, proactive maintenance and replacement program. This includes sourcing high-quality, reliable replacement batteries from a trusted partner, establishing a regular testing and replacement schedule, and ensuring your clinical staff are trained on best practices for battery use.
