Remove the battery by loosening the security screw and sliding the battery pack downward

The Ring Doorbell 2 battery sits inside a removable pack held in place by a single security screw on the bottom of the device. To take it out, you'll need a security screwdriver (the kind with a small square hole, not a Phillips head), about two minutes, and a flat surface to work on. The battery pack slides straight down once the screw is loose — it doesn't twist or require force.

Before you start, make sure the doorbell is powered down. If it's wired to your home's electrical system, turn off the breaker that controls it. If you're running it on battery only, you don't need to do anything first, but powering it down prevents accidental triggers while you're working.

Key Takeaways

  • You need a security screwdriver (square-hole bit) to remove the single screw holding the battery pack in place.
  • The battery pack slides downward and out of the doorbell body once the screw is loose — do not pull sideways or twist.
  • If your doorbell is wired to your home's electrical system, turn off the breaker before removing the battery.
  • The battery pack contains four AA batteries inside; you can replace them without removing the entire pack if you only need to swap batteries.

Locate the security screw on the bottom of the doorbell

Flip the doorbell over or angle it so you can see the bottom. You'll see a small square hole in the center — this is where the security screw sits. This screw is the only thing holding the battery pack in. The hole is small enough that a regular Phillips screwdriver won't fit; you need the security screwdriver with the square bit.

If you don't have a security screwdriver, you can buy one at any hardware store for a few dollars, or order one online. Some multi-bit screwdriver sets include the security bit. It's worth keeping one around because Ring uses this same screw type on most of their devices.

Unscrew and keep the security screw in a safe place

Insert the security screwdriver into the square hole and turn counterclockwise. The screw will come out after two or three full turns — it's not tight, so you won't need to force it. Once it's out, set it somewhere you won't lose it. A small dish or envelope works well.

Losing this screw means you won't be able to find the battery pack back in place, and the pack can fall out or shift during use. If you do lose it, Ring sells replacement screws, or you can use a small stainless steel security screw from a hardware store as long as it's the same size.

Slide the battery pack straight down and out

With the screw removed, hold the doorbell steady with one hand and use your other hand to grip the bottom edge of the battery pack. Pull straight downward in one smooth motion. The pack will slide out of the slot it sits in. Don't wiggle it side to side or try to twist it — straight down is the only direction it moves.

The battery pack is a rectangular plastic case about the size of a deck of cards. Once it's fully out, you'll see the four AA batteries inside through the clear plastic window on the back. If you only need to replace the batteries themselves, you can open this pack right here without removing it from the doorbell — just pop the back cover off and swap the old batteries for new ones.

Check the batteries and reinstall the pack

If you've removed the pack to replace the batteries, open the back cover by sliding it downward and insert four fresh AA batteries with the positive ends facing the correct direction (the diagram inside the pack shows which way). Close the cover and slide the pack back up into the doorbell until it clicks into place. Then reinstall the security screw and turn it clockwise until it's snug — don't overtighten.

If you're removing the pack for another reason — to clean it, to troubleshoot a connection issue, or to replace the entire pack — just set it aside. The doorbell will continue to work on its wired power if it's connected to your home's electrical system. If it's battery-only, the doorbell will be off until you reinstall the pack.

Reinstall the battery pack and screw

To put the battery pack back in, hold it so the bottom edge aligns with the slot on the doorbell. Slide it straight up until you hear or feel a click — this means it's seated properly. Then insert the security screw back into the hole and turn clockwise until it's tight. You don't need to crank it hard; just snug enough that the pack won't move.

Once the screw is in, test the doorbell by pressing the button. You should see the light ring flash and hear the chime inside your home. If nothing happens, the battery pack may not be fully seated — remove the screw again, slide the pack down and back up, and try once more.

Common mistakes to avoid

The most common error is trying to pull the battery pack straight out instead of down. The pack is held in a vertical slot, and pulling outward will jam it. Always pull downward. Another mistake is using the wrong screwdriver — a Phillips head or a regular flathead won't fit the security hole and can strip it, making it impossible to remove the screw later.

Don't leave the battery pack out for long periods if the doorbell is battery-only, because the device will be completely off and won't record motion or ring when someone presses the button. If you're replacing batteries, do it quickly so the doorbell is back in service. Finally, don't overtighten the security screw when you reinstall it — it only needs to be snug, and forcing it can crack the plastic around the hole.

Frequently Asked Questions

Do I have to turn off the power before removing the battery?

If your doorbell is wired to your home's electrical system, turn off the breaker first. If it's battery-only, you don't have to, but powering it down prevents the device from triggering while you're working on it. Turning off the breaker takes 30 seconds and is the safest approach.

What if the security screw is stuck and won't turn?

explore light downward pressure on the screwdriver while turning counterclockwise — this helps the bit grip the hole better. If it still won't budge, try a different security screwdriver in case the bit doesn't fit perfectly. Never force it, as you can strip the hole. If it's truly stuck, contact Ring support for guidance.

Can I replace just the batteries without removing the pack?

Yes. Slide the back cover of the battery pack downward and swap the four AA batteries. You don't need to remove the pack from the doorbell at all. This is the fastest way to replace batteries if that's all you need to do.

What happens if I lose the security screw?

The battery pack will be loose and can fall out or shift during use. You can order a replacement screw from Ring or buy a matching stainless steel security screw from a hardware store. Measure the one you have if you still have it, or contact Ring with your doorbell model number and they can tell you the exact size.

How do I know if the battery pack is seated correctly?

You should hear or feel a click when you slide it all the way up. The pack should not move or rattle when you gently push on it. If you're unsure, remove the screw and try again — it's better to reseat it than to leave it loose.
