Replacement Battery Guide for use with Medfusion 3500, 3010, and 2500

Introduction

Infusion pump battery performance matters for equipment availability. When a Medfusion pump battery no longer holds charge as expected, biomedical teams need a replacement that matches the correct model, OEM reference, voltage, chemistry, and connector style.

This guide explains what to confirm before sourcing a replacement battery for Medfusion 3500, 3010, and 2500 infusion pump models.

Quick Compatibility Checklist

Before requesting a quote, confirm:

Detail	Why It Matters
Pump model	Confirms the battery is intended for the correct Medfusion series
OEM reference	Helps match compatible replacement options
Battery voltage	Must match device requirements
Battery chemistry	Confirms the correct replacement type
Connector or pack style	Helps prevent fit issues
Quantity needed	Supports inventory planning
Shipping urgency	Helps prioritize sourcing from available inventory

Confirm the Exact Pump Model

Do not order a battery based only on the word "Medfusion." Confirm the full pump model, such as 3500, 3010, 3010A, 2500, or another listed compatible model.

The model number may appear on:

• The pump label
• The asset record
• The service documentation
• Prior purchasing records
• The current battery or battery compartment documentation

Check the OEM Reference Number

OEM references help match a replacement battery to the original part. Medten’s homepage promotion references Medfusion infusion pump battery compatibility and OEM references such as 5181 and 67-2515-51.

When requesting a quote, include every reference number available from the battery label, service manual, or previous purchase order.

Confirm Battery Specifications

Battery replacements should be selected based on device requirements, not guesswork. Confirm the required:

• Voltage
• Chemistry
• Capacity
• Connector
• Pack shape
• Device model compatibility
• Facility service procedure

If the existing battery label is readable, photograph it before removal or disposal.

Warning Signs a Battery May Need Replacement

Battery replacement may be needed when:

• Runtime is shorter than expected
• The pump does not hold a charge
• Charging errors appear
• The battery is past facility replacement age
• The battery fails preventive maintenance checks
• The device powers down sooner than expected
• Physical swelling, leakage, or damage is present

Follow facility policy for removing damaged batteries from service.

Keep Replacement Batteries in Inventory

Facilities that maintain multiple infusion pumps often benefit from keeping replacement batteries available. This can reduce downtime when batteries fail during preventive maintenance or routine inspections.

Track:

• Pump model
• Battery reference number
• Quantity in use
• Quantity in stock
• Last replacement date
• Next planned replacement cycle

Safety and Service Notes

Battery replacement should be performed according to the pump manufacturer’s service instructions and your facility’s biomedical engineering procedures. Use only batteries selected for the correct model and specifications.

If you are unsure whether the battery is the cause of a device issue, complete the appropriate diagnostic steps before replacing parts.
