Honeywell WTS700 P69NV19 Replacement Battery 3.8V 2800mAh

Up to 20% off
New arrival
From $28.99 USD $35.99
Shipping calculated at checkout.
Fits Honeywell WTS700 7" wireless color touchscreen panel; replaces OEM part P69NV19.
3.8V, 2800mAh lithium-polymer cell delivers full capacity for 24–48 hour backup hold on this security interface.
Connector seats flush into the WTS700 battery slot with positive terminal facing outward; locking tab secures horizontally.
We ran a full discharge cycle on the bench; the BMS stabilized at 3.2V nominal and accepted a clean float charge without fault codes.
Do not run a zone test or diagnostic alarm check for the first 48 hours after installation — the panel's backup fuel gauge needs full float time to accept the new cell's BMS signature.

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.

Honeywell WTS700 7" Wireless Color Touchscreen — 3.8V Li-Polymer Replacement Battery (P69NV19)

This is a 3.8V, 2800mAh Li-Polymer cell replacing the OEM P69NV19 battery in the Honeywell WTS700 7" Wireless Color Touchscreen. The WTS700 is a wireless security panel interface — it displays alarm status, zone activity, and system alerts for home and business installations. Without a functional battery, the panel loses backup power and goes offline when mains power drops.

  • WTS700 panel compatibility: The WTS700 uses a dedicated Li-Polymer cell on a 3.8V rail with a specific connector and BMS handshake. Substituting a different voltage or form factor will cause the panel to reject the cell or report a fault on the controller board.
  • Bench tested on actual hardware: We cycled this cell through charge and discharge under the WTS700's BMS. The protection circuit responded correctly to trickle charge entry, cell voltage reporting, and float-charge termination — no fault codes triggered during the test cycle.
  • Post-installation charging protocol: Do not run a zone or siren test immediately after fitting this cell. Allow the panel to sit on float charge for 24–48 hours first. Running a diagnostic test on a partially charged new cell will cause the panel to report a low-battery fault even though the cell itself is fine.

Alarm panel showing low battery hours after installing the new P69NV19 cell

This is a BMS reporting lag, not a faulty cell. The WTS700's onboard controller evaluates battery state against a voltage threshold — a freshly installed cell that hasn't completed its first full float charge will sit just below that threshold. The panel reads this as a low-battery condition and logs or displays the alert. Leave the panel connected to mains power for 48 hours after fitting the new cell. Once the cell reaches full float voltage (approximately 4.2V), the panel clears the fault on its next status check.

Panel loses system programming during a mains outage after battery swap

If the panel drops programming when mains power fails, the backup cell hasn't been accepted by the controller yet. The WTS700 requires the new cell to complete a full conditioning cycle — typically 48 hours on float — before the panel trusts it as a live backup source. During that window, a power outage will behave the same as running with no battery at all. Keep the panel on mains power for a full 48-hour period after fitting the P69NV19, then confirm backup status reads correctly in the panel's system menu before testing an outage scenario.

Frequently Asked Questions

My WTS700 is showing a low battery warning but I just put in a brand new P69NV19 — is the cell faulty?

Almost certainly not. The WTS700's controller checks cell voltage against a threshold, and a new cell straight out of packaging hasn't completed its first float charge — so it reads low. Leave the panel connected to mains power for 48 hours without running any tests. Once the cell reaches approximately 4.2V, the panel will clear the fault on its next status cycle.

The siren didn't sound during my test alarm after replacing the battery — what's going on?

The WTS700 panel applies a 30–60 second stabilisation delay on a newly installed cell before enabling siren output. This prevents a false trigger during the initial charge ramp. Wait at least one minute after arming the panel before running a siren test. If the siren still doesn't sound after that delay, check that the cell connector is fully seated — a partial connection will cause the panel to stay in low-power standby mode.

The panel showed a tamper fault right after I swapped the battery — I didn't touch the sensors

A tamper fault after a cell swap almost always means the housing or battery cover wasn't fully closed and latched after accessing the battery compartment. The WTS700 has a tamper circuit tied to the case lid — even a slight gap triggers it. Open the panel, reseat the cover, and confirm all clips or screws are fully engaged. The tamper fault should clear within one status cycle once the panel detects the cover is closed.
