About this replacement
SimpliSafe SSCAM-BAT3 — 3.7V Li-ion Replacement Battery (SSCAM-BAT3)
This 3.7V, 6000mAh Li-ion cell replaces the original SSCAM-BAT3 battery in SimpliSafe wireless security cameras. It fits indoor and outdoor SimpliSafe camera models that rely on battery power for wire-free mounting. Voltage and capacity match OEM spec exactly — 3.7V, 6000mAh (22.2Wh).
- SimpliSafe wireless camera platform: SimpliSafe camera models share the SSCAM-BAT3 form factor because the housing, BMS handshake voltage, and connector are standardised across the indoor and outdoor wire-free line. Swapping to a cell outside that voltage window will cause the camera to reject the pack at firmware level.
- Bench tested on actual hardware: We cycled this cell through motion-trigger events and monitored the BMS response during the combined IR LED and processor current spikes that occur on each trigger. The protection circuit held within tolerance across repeated draw events without tripping into cutoff.
- First-install power cycle: After fitting this cell, power cycle the camera once through the SimpliSafe app. The firmware must re-register the new cell before motion-triggered recording logs correctly to cloud storage — skipping this step can leave the event log blank even when the camera is physically active.
Camera going offline in the app after battery installation
When a SimpliSafe camera loses power entirely — either from a depleted cell or a swap — the firmware session token is dropped. The camera reconnects to Wi-Fi on fresh power, but the app may not re-establish the device link automatically. This shows as "offline" in the app even though the camera LED confirms it has power. Open the SimpliSafe app, navigate to the camera settings, and use the reconnect or re-register option to restore the live feed.
App showing 0% or wrong battery percentage after installing a new cell
SimpliSafe cameras use a voltage-threshold indicator — not a fuel gauge IC — to report battery level to the app. When a new cell is installed, the firmware reads the resting voltage and maps it to a percentage tier. If the cell was stored at reduced voltage during shipping, the initial reading can show 0% or an unexpectedly low figure. Run the camera through one full charge cycle and the voltage reading will settle at the correct threshold tier.
