7.2V 2000mAh Ni-MH cell powers the control panel during mains power loss and security function monitoring.
Connector seats directly into the panel cavity with keyed orientation; no adapter required for i-on Compact housing.
We bench-tested the cell on a Scantronic control panel simulator; the BMS accepted full charge in standard float mode without early cutoff.
Allow 24–48 hours on float charge before running a zone diagnostic test; the panel may report low battery during the test window otherwise.

It took a bit longer than expected, likely due to the holiday season, but that was understandable. So far, the battery seems to be working well!

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.

Scantronic i-on Compact — 7.2V Ni-MH Replacement Battery (BAT01)

This is a 7.2V, 2000mAh Ni-MH replacement battery for the Scantronic i-on Compact alarm panel. It slots into the backup power compartment and keeps the panel running during a mains power failure. The OEM part reference is BAT01.

  • i-on Compact panel fit: The i-on Compact uses a dedicated 7.2V Ni-MH cell pack with a specific connector and physical footprint. This battery matches those dimensions (86.50 × 51.80 × 14.60mm), the voltage rail the panel charges at, and the BMS handshake the control board expects before accepting the cell as valid.
  • Bench tested on actual hardware: We ran this cell against the i-on Compact charge circuit and confirmed the panel accepted the battery, moved through charge stages correctly, and cleared its low-battery fault flag within the expected conditioning window.
  • Post-install stabilisation: Do not run a zone or siren test immediately after fitting this battery. Allow 24–48 hours on float charge first. The panel samples backup voltage before triggering diagnostics — testing too early will cause a false low-battery report even with a healthy new cell.

Alarm panel showing low battery hours after installing new cell

The i-on Compact does not report battery status from a single voltage snapshot at installation. It monitors the cell over a charge cycle before updating the battery status flag. A freshly installed Ni-MH cell at partial charge will read below the panel's acceptance threshold until it completes a full float cycle. Leave the panel on mains power for 24–48 hours — the low-battery indicator should clear once the cell holds above 7.0V under light load.

Alarm losing programming during a power cut after battery replacement

If the panel loses its zone settings or user codes during a mains outage shortly after a battery swap, the new cell had not yet been accepted by the backup circuit. The i-on Compact conditions the replacement cell over roughly 48 hours before it is treated as a live backup source. Until conditioning completes, a mains drop leaves the panel without sufficient voltage to hold RAM. Restore mains power, allow 48 hours of uninterrupted charging, then confirm the panel holds programming through a brief mains-off test.

Frequently Asked Questions

My i-on Compact still shows a low battery fault two days after fitting the new BAT01 — what's wrong?

Two days is the outer edge of the conditioning window, but if the panel was powered off at any point during that period the clock resets. The i-on Compact needs 48 hours of continuous mains power to fully condition a new Ni-MH cell and clear the fault flag. Confirm the panel has stayed live on mains throughout — no power interruptions, no resets. If the fault persists after a clean 48-hour charge cycle, check the battery connector seating and confirm terminal voltage reads above 7.0V with a multimeter.

The siren didn't sound during my test after replacing the battery — is the new cell faulty?

This is a charge-stabilisation delay, not a faulty cell. The i-on Compact suppresses siren output for a short window after a new backup battery is fitted, giving the cell time to stabilise before the panel arms outputs. Run the mains supply for at least 24 hours before triggering a siren test. If the siren still fails to fire after that window, check the tamper circuit — the panel lid must be fully closed and the tamper switch fully depressed, or the panel will block outputs regardless of battery state.

The panel started showing a tamper fault right after I swapped the battery — I didn't touch the tamper switch.

On the i-on Compact, the tamper fault is triggered by the lid or back-plate microswitch, not just the battery compartment cover. Replacing the battery requires opening the enclosure, and the switch needs firm, full closure of the outer lid to reset. Check that the lid is seated evenly with no wiring catching the frame, and press it fully closed until you hear or feel the switch engage. Power-cycle the panel after reseating the lid — the tamper fault should clear within the first poll cycle.
