Insignia TV Remote Batteries: Size, Type, and Replacement

Quick Answer: Most Insignia TV remotes use two AAA batteries, including many standard Insignia infrared remotes, Insignia Roku TV remotes, and Insignia Fire TV voice remotes. To replace them, open the battery cover on the back, remove both old batteries, and insert two fresh AAA batteries according to the positive (+) and negative (−) markings.
Always check your remote’s battery compartment or model-specific manual before inserting batteries. If the remote still does not work, the problem may involve battery contacts, Bluetooth pairing, or the television itself.
What Batteries Does an Insignia TV Remote Use?
The most common battery size for Insignia television remotes is AAA.
However, Insignia has produced different television models and remote designs. The battery requirement should be confirmed using the remote’s model number or the markings inside its battery compartment.
Insignia Remote Battery Size by Type
| Insignia Remote Type | Common Battery Requirement | What to Check |
|---|---|---|
| Standard Insignia TV remote | 2 AAA | Battery compartment or TV manual |
| Insignia Fire TV voice remote | 2 AAA on common models | Exact remote model |
| Insignia Roku TV remote | 2 AAA on documented models | TV manual and compartment |
| Insignia replacement IR remote | Often 2 AAA | Replacement product instructions |
| Third-party universal remote | Varies | Universal remote manufacturer |
For example, the official Insignia manuals for the NS-39D220NA16, NS-43D420NA16, and NS-50D420NA16 televisions specify two AAA batteries.
The Insignia Roku TV manual for NS-32DR420NA16 and NS-55DR420NA16 also specifies two AAA batteries.
If you have a different model, verify its requirements rather than assuming every Insignia remote is identical.
How to Check Your Insignia Remote Battery Size
- Turn the remote over.
- Locate the battery cover.
- Open the compartment carefully.
- Look for the battery size printed or molded inside.
- Check the markings on the old batteries.
- Compare the information with your TV or remote manual.
A battery labeled AAA is smaller than an AA battery. They are not interchangeable.
Do not force a battery into a compartment that appears too small.
Insignia Fire TV Remote Batteries
Many Insignia Fire TV voice remotes use two AAA batteries.
Amazon recommends AAA alkaline batteries for supported Fire TV remotes.
To check the exact requirement:
- Open the remote’s battery compartment.
- Read the battery-size markings.
- Confirm the quantity.
- Insert the specified batteries.
A Fire TV voice remote may use Bluetooth for navigation and voice features, so replacing the batteries does not necessarily resolve a lost pairing connection.
Insignia Roku TV Remote Batteries
Documented Insignia Roku TV remotes, including those supplied with the NS-32DR420NA16 and NS-55DR420NA16 models, use two AAA batteries.
To replace them:
- Open the rear compartment.
- Remove both batteries.
- Insert two fresh AAA batteries.
- Match the polarity markings.
- Reattach the cover.
A standard infrared Roku TV remote generally works without pairing. A compatible wireless voice remote may require pairing.

Alkaline vs. Rechargeable Batteries
For most users, fresh AAA alkaline batteries are a straightforward choice.
Some supported Fire TV remotes also permit 1.2V NiMH rechargeable AAA batteries, as described in Amazon’s safety documentation.
| Battery Type | Typical Nominal Voltage | Considerations |
|---|---|---|
| AAA alkaline | 1.5V | Common choice for TV remotes |
| AAA NiMH rechargeable | 1.2V | Supported by certain models; use a suitable charger |
| AAA lithium primary | Depends on chemistry | Use only when the remote manufacturer permits it |
Never substitute a battery with a different size or incompatible chemistry.
Do not mix alkaline and rechargeable batteries in the same remote.
How to Change Insignia TV Remote Batteries
Changing the batteries is straightforward on most models, but a few remotes have covers that trip people up.
Standard Cover Removal
Most Insignia remotes have a cover on the back that slides off or pops open with light thumb pressure near the bottom edge. Remove the old batteries, insert the new ones matching the polarity markings, and slide the cover back on until it clicks.
Apply pressure near the bottom edge or at the notch rather than forcing the middle of the cover, which can crack it. The right spot needs only light, steady pressure.
Replacing Both at Once
Always replace both Insignia TV remote batteries at the same time rather than one at a time. A mismatched pair — one fresh, one drained — leaves the remote underpowered and causes intermittent glitches that look like a bigger fault.
This is one of the most overlooked causes of a remote that seems to fail again quickly after a battery change, when the real issue was simply an unbalanced pair.
Changing Batteries Without a Cover
If the battery cover is lost, insert the batteries matching the polarity markings and secure them with a small piece of tape over the compartment to maintain contact. It’s a temporary fix that keeps the remote working until you find the cover or replace the remote.
Inexpensive replacement covers are available for many popular remote models if you’d rather not rely on tape long-term, or you can switch to a phone app entirely.
When New Batteries Don’t Fix the Remote

One of the most frustrating problems is a remote that won’t work even with fresh Insignia TV remote batteries. This narrows the cause considerably, because it rules out the batteries themselves.
If genuinely fresh batteries produce no response, the issue is usually one of three things: the remote lost its pairing, the TV is frozen, or the remote has a hardware fault. Working through these in order resolves nearly every case.
Re-Pair the Remote
For a Fire TV remote, a lost pairing is the most likely cause when new batteries don’t help. Hold the home button for about 10 seconds with the TV on to re-pair. This is the step people most often skip when new Insignia TV remote batteries don’t revive the remote.
If the batteries are genuinely fresh, re-pairing is far more likely to be the actual fix than buying yet another set.
Restart the TV
A frozen TV can ignore a perfectly good remote. Unplug the TV for 30 seconds, plug it back in, and let it fully boot before testing the remote again with the new batteries installed.
Give it the full 30 seconds unplugged rather than a quick off-and-on, since a rushed reconnection can leave the same glitch in place.
Test for a Hardware Fault
For an infrared remote, point it at a phone camera and press a button — a working remote shows a faint light on the camera screen. No light after fresh Insignia TV remote batteries means the remote hardware has failed and needs replacing, not more batteries.
This camera test is the most decisive check for an infrared remote, cleanly separating a battery problem from a genuine hardware failure so you’re not guessing.

How Long Do Insignia Remote Batteries Last?
Battery life varies by remote type and usage, but there’s a rough pattern worth knowing so you can plan ahead.
A standard infrared Insignia remote sips power and can run for many months to a year on one set of Insignia TV remote batteries. Fire TV voice remotes with Bluetooth and a microphone draw more power and typically need fresh batteries more often, especially with heavy voice-search use.
Signs Your Batteries Are Low
The first sign is usually a remote that responds slowly or intermittently rather than dying outright. A sluggish remote is often showing an early low-battery symptom, so a fresh set frequently restores full speed before an outright failure.
Catching this early lets you swap batteries before the remote fails completely, avoiding the mid-show scramble for spares.
Making Batteries Last Longer
Using quality alkaline batteries and storing the remote where no button gets pressed accidentally both extend how long a set lasts. A key jammed against a surface drains batteries quickly, so keep the remote where nothing rests on it.

Common Battery Mistakes to Avoid

A few avoidable errors turn a simple battery swap into a confusing troubleshooting session.
Mixing Old and New Batteries
Pairing one fresh battery with one half-drained one leaves the remote underpowered and behaving erratically. Always replace both Insignia TV remote batteries at the same time.
Reversing the Polarity
Installing a battery backwards is easy to do in low light and stops the remote from working entirely. Double-check that each battery’s flat negative end sits against the spring, matching the markings inside.
