About this replacement
SimpliSafe Wireless Security Camera — 3.7V Li-ion Replacement Battery (SSCAM-BAT3)
This 3.7V 7000mAh (25.9Wh) Li-ion cell replaces part number SSCAM-BAT3 in the SimpliSafe wireless security camera. It restores full battery-only operation when the original cell has degraded past usable capacity. The physical dimensions — 66.20 × 37.00 × 19.10mm — match the OEM housing exactly.
- SimpliSafe camera platform fit: SimpliSafe wireless cameras run a single-cell 3.7V architecture with a dedicated BMS that monitors cell voltage before enabling the motion sensor, IR LEDs, and WiFi radio. Any cell installed must meet the BMS re-entry voltage threshold — this replacement does.
- Bench tested on actual hardware: We cycled this cell through the SimpliSafe camera's charge circuit and confirmed the BMS accepted the cell at rest voltage, passed the motion-trigger current spike without cutoff, and held WiFi connection through repeated reconnect events.
- First-install power cycle: After fitting the new cell, power cycle the camera once through the SimpliSafe app. The firmware must register the new cell before motion recording logs correctly to cloud storage — skipping this step can leave motion events unrecorded even when the camera appears online.
Camera going offline in the app after battery installation
When you swap the cell, the camera loses its session token — the app's connection to that camera drops and may not recover automatically. This is a firmware handshake issue, not a fault with the battery or the camera hardware. Open the SimpliSafe app, navigate to the camera settings, and remove then re-add the device. The camera re-registers at that point and resumes normal online status.
App reporting 0% or an incorrect charge level after swap
SimpliSafe cameras use a voltage-threshold indicator to report battery percentage — there is no fuel gauge IC tracking charge history. When a new cell is installed, the indicator starts from a blank state and can display 0% or stall at a low number until the cell completes one full charge cycle. Run the camera through a full charge from the dock to 4.2V, then discharge it through normal use. After that first complete cycle, the percentage reading in the app will track accurately.
