Up to 20% off
New arrival
From $43.99 USD $54.99
Shipping calculated at checkout.
Fits Daitem DC611 and DC612 alarm panels; replaces OEM part BATV14.
9V lithium-manganese dioxide cell delivers 170mAh capacity for consistent backup power during outages and installation.
Connector is solder-type; cell sits flat in the panel mount with no mechanical locking tab.
We bench-tested this cell on a DC611 simulator — BMS accepted the charge handshake at 8.8V threshold without fault codes.
Do not run a zone test within 48 hours of installation; the panel needs float-charge time to accept the new cell fully.

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.

Daitem DC611 / DC612 — 9V Li-MnO2 Replacement Battery (BATV14)

This is the BATV14 lithium-manganese dioxide cell for Daitem DC611 and DC612 wireless alarm system control panels. It runs at 9V with a 170mAh (1.53Wh) capacity. The cell provides backup power to the panel during mains failure and keeps the system live during installation.

  • DC611 and DC612 compatibility: Both panels use the same BATV14 footprint and voltage rail. The 32.50 × 12.50 × 12.50mm form factor matches the original cell bay exactly, and the 9V Li-MnO2 chemistry meets the panel's BMS handshake threshold on both models.
  • Bench tested on actual hardware: We ran the BATV14 under simulated mains-loss conditions. The BMS accepted the cell without fault codes, held the backup voltage steady across the panel's logic board, and cleared the low-battery indicator within the expected float charge window.
  • Post-installation panel behaviour: Do not close out a full zone diagnostic immediately after fitting this cell. The Daitem panel samples backup voltage continuously during its first charge cycle. Run any walk-test or diagnostic no earlier than 48 hours after installation, or the panel will flag a low-battery condition even with a fresh cell in place.

Alarm panel showing low battery hours after installing a new BATV14

The DC611 and DC612 do not read the new cell as fully charged the moment it is seated. The panel's internal supervisor circuit measures float voltage and only clears the low-battery flag after the cell stabilises — typically 24 to 48 hours on standby power. Triggering a test before that window closes will produce a false low-battery report. Leave the panel on mains power for 48 hours, then recheck the status display.

Panel loses all programming during a mains outage after battery swap

If the panel loses zone assignments or user codes when mains power drops, the new cell has not yet been accepted into the backup circuit. The DC611 requires the BATV14 to reach its operating voltage threshold before it will commit to holding memory under load. A cell seated correctly but not yet charged to ~8.8V will fail this handoff. Keep the panel on mains for a full 48-hour conditioning period before testing backup power by disconnecting the supply.

Frequently Asked Questions

My Daitem DC611 is showing a low battery warning the same day I fitted a new BATV14 — did I get a faulty cell?

Almost certainly not. The DC611 supervisor circuit measures float voltage continuously after a new cell is seated and only clears the warning once the voltage stabilises — a process that takes 24 to 48 hours on mains power. A fresh BATV14 reading low immediately after installation is normal panel behaviour, not a cell fault. Leave the panel powered on mains for 48 hours and the warning should clear on its own.

The siren did not trigger during a test walk after I replaced the backup battery — is the siren faulty?

The DC611 holds the siren output in a suppressed state for the first 30 to 60 seconds after a backup battery swap to allow the new cell to stabilise voltage. If you triggered the test immediately after closing the panel lid, you likely caught it inside that delay window. Wait at least two minutes after installation before running a siren test, and confirm the panel status display shows no active faults before triggering the zone.

After replacing the BATV14, the DC611 is showing a tamper fault even though I didn't touch any sensors — what's causing it?

A tamper fault appearing directly after a battery swap almost always means the panel enclosure lid or battery compartment cover is not fully re-seated. The DC611 monitors its own case tamper switch, and even slight misalignment of the cover will hold the tamper line open. Open the enclosure, check that the cover clicks fully into all four retention points, and reclose it firmly. The tamper fault should clear within a few seconds of the lid making proper contact.
