What Is the Genie ACSCTG Type 3 Remote?

What Battery Does the Genie ACSCTG Type 3 Remote Use?
The Genie ACSCTG Type 3 remote uses a CR2032 lithium coin cell battery — the same kind found in many key fobs and small electronics.
Here’s a quick comparison to understand the specs:
| Battery Model | Voltage | Diameter | Thickness | Average Lifespan |
|---|---|---|---|---|
| CR2032 | 3V | 20mm | 3.2mm | 2–3 years |
| CR2025 | 3V | 20mm | 2.5mm | 1.5–2 years |
💡 Pro Tip: Always check the number printed on your old battery. “2032” and “2025” look similar, but they differ slightly in thickness and capacity.
How to Replace Genie Garage Door Opener Remote Battery ACSCTG Type 3
Changing the battery takes only a few minutes. Follow these step-by-step instructions carefully:
1. Gather the Right Tools
You’ll need:

3. Remove the Old Battery
- Gently lift the old coin cell from the slot using your screwdriver tip or fingernail.

Troubleshooting: When the Remote Still Doesn’t Work
If your Genie ACSCTG Type 3 still doesn’t work after replacing the battery, check these possible issues:
1. Battery Inserted Incorrectly
Make sure the + (positive) side faces upward. Reversed polarity prevents electrical contact.
2. Dirty Battery Contacts
Corrosion or dirt can block power flow. Clean contacts with a cotton swab dipped in isopropyl alcohol, then let dry completely before reinserting the battery.
3. Remote Needs Reprogramming
If the battery was out for too long, your remote might lose its link to the opener.
To reprogram:
- Press and hold the “Learn” button on your Genie opener until its indicator light begins blinking.
- Within 30 seconds, press and hold the remote button you wish to program.
- Release both once the opener light flashes or you hear a click.
Your remote should now function properly.
4. Faulty Remote Circuitry
If nothing works, the internal circuit board might be damaged. Replacements cost about $25–$45 and are widely available at major retailers or online.
How Long Does the CR2032 Battery Last?
The CR2032 typically lasts 2 to 3 years, depending on usage. However, factors such as cold weather, frequent operation, or poor battery quality can reduce lifespan.
According to Wikipedia, lithium coin cells have a shelf life of 8–10 years when stored properly — making them an ideal long-term choice for remotes and small devices.
Battery Maintenance and Longevity Tips
To get the most out of your new battery:
- Store spares in a cool, dry place. Extreme heat shortens lithium battery life.
- Avoid moisture exposure. Water or condensation can corrode metal contacts.
- Use name-brand batteries. Energizer, Panasonic, or Duracell perform best.
- Test every 6 months. If the LED is dim, it’s time for replacement.
- Remove the battery if you won’t use the remote for several months.
CR2032 vs. CR2025: Which Is Better for Genie ACSCTG Type 3?

|---|---|---|
| Power Capacity | Higher | Lower |
| Battery Life | 2–3 years | 1.5–2 years |
| Compatibility | Recommended | Backup Option |
| Price | Slightly higher | Slightly cheaper |
✅ Verdict: The CR2032 is the best choice — it lasts longer and provides more stable voltage for Genie remotes.
