Nearly 31 million U.S. households rely on Flexible Spending Accounts (FSAs) to cover qualified out-of-pocket medical expenses each year, but many leave hundreds of dollars in unused benefits on the table because they don’t know which everyday items qualify. If you’ve ever grabbed a pack of AA batteries for your blood glucose monitor, TV remote, or kids’ toy, you’ve probably wondered: Are Batteries FSA Eligible? The answer isn’t a simple yes or no, and navigating the FSA’s strict eligibility rules can feel overwhelming for even the most organized budgeter. By the end of this guide, you’ll know exactly which batteries qualify for FSA reimbursement, which items don’t, and how to keep track of your purchases to avoid denied claims.
The Short Answer: Are Batteries FSA Eligible?
The short answer is that batteries are only FSA-eligible if they power a qualified medical device prescribed by a licensed healthcare provider. Most standard batteries for everyday electronics like TV remotes, wireless headphones, or gaming controllers don’t count toward your FSA reimbursement limits, but batteries that keep life-saving or chronic condition management tools running do. The IRS’s strict guidelines tie FSA eligibility directly to medical necessity, so any battery used to power a non-prescription, non-medical device is off-limits. For example, a pack of AAA batteries for your smart watch won’t qualify, but the same size batteries for your hearing aid’s backup charger will.
Which Medical Devices Require FSA-Eligible Batteries?
When most people think of FSA-eligible medical devices, they picture big, bulky equipment, but many small, daily-use tools rely on replaceable batteries that count toward your FSA funds. You might not even realize that the small gadgets you use to manage your health fall under IRS guidelines, so it’s worth taking stock of what you already own.
Here are some of the most common qualified medical devices that use FSA-eligible batteries:
- Hearing aids and their charging cases
- Portable nebulizers for asthma treatment
- Blood glucose meters and test strip lancing devices
- Continuous glucose monitors (CGMs) and their transmitters
- Portable oxygen concentrators for travel
- TENS units for pain management
Each of these devices requires replacement batteries from time to time, and as long as you have a prescription or a written recommendation from your doctor for the device itself, you can submit the battery purchase for reimbursement. Keep in mind that you don’t need a separate prescription for the batteries, just proof that the device is a qualified medical expense.
For example, if you use a CGM to manage your type 1 diabetes, you can buy the CR2032 batteries that power its transmitter and submit the receipt to your FSA administrator, no extra paperwork beyond your existing CGM documentation required.
How to Prove Your Batteries Are FSA-Eligible
Even if you’re buying batteries for a qualified medical device, you can’t just submit a random receipt and get reimbursed. The IRS requires clear documentation that links the batteries to a qualified medical expense, so you need to keep track of your purchases carefully.
Most FSA administrators will accept one of these types of proof:
- A written prescription from your doctor stating that you need the medical device
- A copy of the device’s manual or packaging that notes it requires replaceable batteries
- A receipt from a licensed medical supply store that lists both the device and the batteries
- A personal note from you that explains how the batteries power a qualified medical device, paired with a photo of the device
Many people make the mistake of only keeping the store receipt for their batteries, which is often not enough on its own. For example, a CVS receipt that says “AA batteries” won’t be approved unless you can show that those batteries were used for your hearing aid, not your TV remote.
Some FSA providers even offer mobile apps that let you snap a photo of your receipt and tag it with the relevant medical device, which can streamline the reimbursement process and reduce the chance of your claim being denied. Make sure to check with your specific FSA administrator to learn their exact documentation requirements.
Common Mistakes That Lead to Denied FSA Battery Reimbursements
Even if you know which batteries qualify for FSA funds, it’s easy to make small mistakes that get your claim rejected. These errors can cost you hundreds of dollars in unused benefits, so it’s important to avoid them at all costs.
Here are the top three most common mistakes that lead to denied battery reimbursement claims:
- Buying batteries for non-qualified devices like TV remotes or wireless headphones
- Failing to keep documentation that links batteries to a qualified medical device
- Submitting claims after your FSA plan’s deadline
One of the most frequent individual mistakes is buying batteries for non-qualified devices and trying to submit them for reimbursement. For example, batteries for your wireless mouse, smart thermostat, or portable speaker will never be approved, even if you use those devices to make your daily routine easier.
A 2023 survey by the Flexible Spending Account Administrators Association found that 41% of denied FSA claims were due to missing or incomplete documentation, including battery purchases that lacked proof of medical use. Finally, many people forget that FSA funds are often use-it-or-lose-it (unless their plan offers a grace period or rollover option), so you need to submit your claims before the deadline to avoid losing out on the money you set aside. Double-check your plan’s rules for filing claims to make sure you don’t miss the cutoff.
Where to Buy FSA-Eligible Batteries
You can buy FSA-eligible batteries at most major retailers, but some stores make it easier to track your qualifying purchases than others. Knowing where to shop can help you streamline your reimbursement process and save time come tax season.
Here’s a breakdown of popular retailers and their policies for FSA-eligible battery purchases:
| Retailer | FSA Eligibility Notes |
|---|---|
| Walmart | Offers in-store and online FSA eligible purchases; requires itemized receipts |
| CVS Pharmacy | Labels medical supply items including qualifying batteries; accepts digital receipts |
| Amazon | Allows you to filter for FSA-eligible items; saves purchase history for reimbursement |
| Local Medical Supply Stores | Often pre-approves battery purchases for medical devices; provides detailed receipts |
Online retailers like Amazon make it especially easy to sort for FSA-qualified products, so you can quickly find the batteries you need for your medical device without having to sort through non-qualifying options. Many of these stores also send you a receipt that clearly labels the item as a medical supply, which speeds up the reimbursement process.
If you shop at a big-box store like Target or Home Depot, make sure to ask the cashier to ring up your batteries under the medical supply category if you’re buying them for a qualified device, which can help your FSA administrator verify your claim more quickly.
Special Rules for Non-Prescription Medical Device Batteries
You might assume that only prescription medical devices qualify for FSA-eligible batteries, but that’s not always the case. The IRS allows FSA funds to be used for batteries that power over-the-counter (OTC) medical devices that are used to treat or prevent a medical condition.
For example, a blood pressure monitor you buy at Walmart without a prescription still counts as a qualified medical device, so its replacement batteries are eligible for FSA reimbursement. The key difference is that you need to keep proof that the device is being used for medical care, even without a prescription.
Some OTC medical devices that qualify for FSA-eligible batteries include:
- Over-the-counter blood pressure monitors
- Digital thermometers
- Pill organizers with reminder alarms
- Portable inhaler charging cases
Just like with prescription devices, you’ll need to keep a receipt that shows the batteries were purchased for the OTC medical device, so make sure to note the purchase on your receipt or keep a separate note explaining the use.
Battery Eligibility for HRAs and HSAs
While we’ve focused on FSA eligibility for batteries, it’s worth noting that other tax-advantaged health accounts have similar rules, with a few key differences. Health Savings Accounts (HSAs) and Health Reimbursement Arrangements (HRAs) also cover qualified medical device batteries, but their guidelines vary.
HSAs follow the exact same IRS rules as FSAs, so batteries for prescribed or OTC medical devices are eligible for reimbursement. The main difference is that you can only contribute to an HSA if you have a high-deductible health plan, and unused HSA funds roll over from year to year indefinitely.
HRAs, on the other hand, are funded entirely by your employer, so their rules for battery reimbursement are set by your company, not the federal government. Some HRAs may cover batteries for non-medical devices, but most follow the same guidelines as FSAs and HSAs.
If you have both an FSA and an HRA (or HSA), make sure to use the right account for each purchase. For example, you can use HSA funds for eligible battery purchases even if you don’t have a high-deductible plan, but you’ll need to follow your employer’s HRA rules for reimbursement.
Now that you know exactly which batteries qualify for FSA reimbursement, you can stop leaving money on the table and start using your FSA funds to cover the medical devices you rely on every day. Remember, the key difference between eligible and ineligible batteries is whether they power a prescribed or over-the-counter medical device, so always double-check before you make a purchase. Taking a few extra minutes to keep track of your receipts and documentation can save you hundreds of dollars in denied claims each year.
If you’re ready to start using your FSA funds for eligible battery purchases, take a few minutes to review your plan’s rules and deadlines first. You can also talk to your doctor or FSA administrator if you have questions about specific devices or purchases, to make sure you’re following all the guidelines.
