Fits Ring Video Doorbell 2 and replaces OEM part 8AB1S7-0EN0.
3.7V and 5200mAh capacity sustains motion detection and two-way audio between charge cycles.
Connector slides into the battery slot with a single locking tab — tab must seat fully or the doorbell won't power on.
We tested this cell on a Video Doorbell 2 unit; the BMS accepted the new pack without fault codes and delivered stable voltage under IR LED load.
On first install, power cycle the doorbell once through the Ring app — firmware must register the new cell before motion recording triggers log correctly to cloud.

Battery Care Tips

🔹 Getting Started

Charge your new battery fully before you use it for the first time. Over the next few charge cycles, run your device down to around 20% before you recharge—this helps the battery perform its best. After that, charge whenever you need to.

🔹 Keep It Healthy

Avoid letting your battery completely drain or staying plugged in constantly. Both extremes wear it out faster. Store the battery in a cool, dry place when you're not using it, since heat damages batteries quickly.

Delivery and Shipping

🔹 Most orders ship the next day, and we use FedEx, UPS, Purolator and other carriers to get them to you. Lithium batteries have to ship by ground only, not air or USPS. Make sure your address is right before you order, because if we have to send it back, you pay for shipping again.

Ring Video Doorbell 2 — 3.7V Li-ion Replacement Battery (8AB1S7-0EN0)

This 3.7V, 5200mAh Li-ion cell is a direct replacement for the Ring Video Doorbell 2 (8VR1S7), Video Doorbell 3 Plus, and Spotlight Cam. It slots into the same battery bay and connects via the original contacts. Fits all models sharing the 8AB1S7-0EN0, V4, 5AT3S3, and 5F53E9 OEM part numbers.

  • Multi-model compatibility — Video Doorbell 2, 3 Plus, and Spotlight Cam: These devices share a common 3.7V battery bay, contact layout, and BMS handshake protocol. One cell works across the platform without modification.
  • Bench tested on actual hardware: We cycled this cell through full charge and discharge on a Video Doorbell 2 unit. The BMS reported correct voltage thresholds at every stage, and motion recording logged without interruption across multiple triggered events.
  • First-install power cycle — do this before mounting: After inserting the battery, trigger a manual power cycle through the Ring app before reinstalling the faceplate. The doorbell's firmware must register the new cell before motion event timestamps and cloud upload sessions sync correctly.

Why the Video Doorbell 2 goes offline in the app after a battery swap

Swapping the battery interrupts power long enough for the doorbell to drop its authenticated session with Ring's cloud servers. The device comes back online at the hardware level, but the app loses its registered token. This shows as "offline" even though the doorbell's LED is lit. Open the Ring app, go to Device Health, and use the reconnect prompt — this re-establishes the session without a full factory reset.

App reporting 0% or incorrect charge percentage after installation

Ring doorbells use a voltage-threshold indicator, not a fuel gauge IC. When a new cell is installed, the firmware has no stored discharge curve to reference, so it defaults to 0% or an arbitrary low reading. Run one full charge cycle via the included cable or Quick Release Charger until the app confirms 100%. After that single cycle, the voltage curve maps correctly and percentage readings stabilise.

Frequently Asked Questions

My Ring Doorbell 2 stops detecting motion after I put in the new battery — what's wrong?

The IR LED array and the motion processor draw current simultaneously during a detection event, and if the firmware hasn't completed cell registration, the BMS can suppress that combined spike as a protection response. The result is motion events that don't trigger or don't log to the cloud. Power cycle the doorbell once through the Ring app immediately after install — go to Device Settings, then press the orange button on the back for 10 seconds — and let it fully reconnect before testing motion zones.

The recording cuts out halfway through a motion clip — is this a battery fault?

Mid-clip dropout is almost always a WiFi reconnect event, not the battery itself. When signal drops briefly, the doorbell attempts to re-establish the stream, and the reconnect current spike can trip the BMS if the cell is cold or recently installed. Check the RSSI value in Device Health — anything weaker than -60 dBm will cause intermittent dropout. Move your router closer or add a Ring Chime Pro to extend signal, and the cutoffs will stop.

My Spotlight Cam drained this battery overnight even though nothing triggered it — why?

Sustained IR LED draw during extended night vision keeps the processor active all night, which pulls significantly more current than standby mode. If the camera is pointed at a high-traffic area with frequent IR activation — even below the motion sensitivity threshold — the cell discharges faster than expected. In the Ring app, go to Light Settings and set the motion-triggered light timeout to the shortest interval, then reduce IR sensitivity one step. Check the battery voltage via Device Health the next morning — it should sit above 3.5V after a full night if the draw is normal.
