Genie remotes are designed to provide long-lasting, reliable transmission, but like any battery-powered device, they eventually need a fresh power source. When a Genie remote begins losing range, working only at close distance, or stops responding completely, the problem is almost always the battery — not the opener and not the remote’s programming.
Because Genie has released a wide range of remotes over the years, identifying the correct Genie garage door opener remote battery size is essential. Most modern Genie remotes use a 3-volt lithium coin cell, while older ACSCTG models may require different battery types depending on whether they are Type 1 or Type 3.
This guide covers all major Genie remote battery types, the correct size for each model, and common troubleshooting steps.

Battery Types Used in Genie Remotes
CR2032 — the most common Genie remote battery
This is the standard battery for most modern Genie remotes. If you are searching for “genie garage door opener remote batteries,” “battery for Genie remote,” or “genie garage door opener remote battery type,” the CR2032 is almost always the correct replacement.
CR2025 / CR2016 — used in older or slim Genie remotes
Some legacy Genie IntelliCode remotes — especially ACSCTG Type 1 — use thinner coin cells such as CR2025 or CR2016. They deliver the same 3V output but fit remote housings with less internal space.
Specialty cells in certain legacy models
A few older Genie remotes require specific coin cell formats because of casing thickness or contact spacing. This is especially relevant for searches like “genie garage door opener remote battery ACSCTG type 1 / type 3.”
Genie Remote Battery Table
| Remote Model | Device Type | Battery Type | Voltage | Notes |
|---|---|---|---|---|
| GICT390 | 3-button remote | CR2032 | 3V | One of Genie’s most common IntelliCode remotes. |
| G1T / G2T / G3T Series | Modern 1-/2-/3-button remotes | CR2032 | 3V | Current Genie lineup; compact and efficient. |
| ACSCTG Type 1 | Classic IntelliCode remote | CR2025 or CR2016 | 3V | Slim housing requires a thinner coin cell. |
| ACSCTG Type 3 | Updated IntelliCode remote | CR2032 | 3V | Later version accepts the thicker CR2032 cell. |
| GM3T Mini-Remote | Keychain remote | CR2032 | 3V | Small form factor with IntelliCode support. |

Short Note on Battery Replacement
Replacing a Genie remote battery is simple: open the case using the small side slot or rear cover, remove the old coin cell, and insert a new one with the positive (+) side facing up. Once the case is closed, the remote should immediately regain its normal range.
Genie Remote Backup Guide (Troubleshooting After Battery Change)

Even with a fresh battery installed, some remotes may still not respond. These are the most common fixes:
1. The LED lights up but the opener does not respond
The battery may not be fully seated or polarity may be reversed.
2. Lost programming after battery change
Older remotes may require reprogramming:
– Press the Program/Learn button on the opener,
– Press and hold the remote button until the opener light blinks.
3. Weak or inconsistent range
Cheap coin cells often provide unstable voltage. Switching to a high-quality CR2032 usually restores reliability.
4. Remote works indoors but not outdoors
Interference from LED bulbs, metal structures, or signal reflections can weaken transmission.
5. Intermittent operation
Dust or oxidation inside the battery tray can disrupt contact. Cleaning the contacts usually resolves the issue.
FAQ — Genie Garage Door Opener Remote Batteries
What battery does a Genie garage door opener remote use?
Most Genie remotes use a 3V CR2032 lithium coin cell. Some slim IntelliCode remotes use CR2025 or CR2016 depending on the model.
What battery does the Genie ACSCTG remote use?
ACSCTG Type 1 uses a thinner coin cell such as CR2025 or CR2016. ACSCTG Type 3 typically uses a CR2032 coin cell.
What battery does the Genie GICT390 remote use?
The GICT390 IntelliCode remote uses a 3V CR2032 lithium coin cell.
What is the correct Genie remote battery size?
The correct size depends on the model: CR2032 for most remotes, and CR2025/CR2016 for older slimmer units.
Why did my Genie remote stop working after changing the battery?
The battery may be reversed, not fully seated, or the remote may need to be reprogrammed. Older Genie remotes lose memory when the battery is fully drained.
How often should I replace a Genie remote battery?
Every 1–2 years, or sooner if the range becomes weak or inconsistent.
Can I use rechargeable coin cells in a Genie remote?
No. Rechargeable coin cells have lower voltage and can cause weak transmission, poor range, and unpredictable behavior.
