GRACO iMonitor Replacement Battery 3.6V 700mAh BATT-2795

GRACO iMonitor 2795DIGI1 Series — 3.6V Ni-MH Replacement Battery (BATT-2795)

This is a 3.6V 700mAh Ni-MH rechargeable battery for the GRACO iMonitor parent unit. It fits the iMonitor, iMonitor Vibe, 2791DIGI1, 2795DIGI1, and several related models. When the original cell stops holding charge, the parent unit loses the ability to operate away from the dock.

• iMonitor parent unit compatibility: These models share a three-cell Ni-MH pack at 3.6V with the same footprint and connector orientation. The BMS on the parent unit expects the correct internal resistance profile — a mismatched cell causes premature low-battery alerts even on a full charge.
• Bench tested on actual hardware: We cycled this battery through the parent unit's charge circuit and confirmed the BMS accepted the charge without false-low flags. Cell voltage at full charge measured within the expected Ni-MH ceiling, and the unit powered the screen and radio module without voltage sag.
• Wireless re-pair after replacement: The iMonitor parent unit loses its camera link when battery power drops to zero. After fitting this battery and charging, navigate to the camera search function in the parent unit menu and re-sync — the unit will not reconnect automatically after a full power loss.

Parent unit range reduced after battery swap

The iMonitor's radio transmitter pulls from the same 3.6V pack that powers the screen and mic. At low state of charge, the radio module drops output power first — the unit stays on, but signal drops and the camera feed stutters or cuts entirely. This is often mistaken for a faulty replacement battery. Charge the parent unit for a full cycle after fitting the new pack, then retest range before concluding there is a fault.

Night vision stops working after fitting a new battery

The IR LEDs in the camera unit are powered by the camera's own supply, but the parent unit's IR display rendering draws extra current from the pack. If the replacement battery is not fully charged before first use, the parent unit may disable IR mode to protect against undervoltage. Fit the battery, charge to full before switching the unit on, and IR mode should initialise correctly. If it does not, confirm the camera unit is still paired — a dropped wireless link will also prevent night vision from displaying on the parent screen.
