Trilogy DL2700CR Replacement Battery 7.5V 2600mAh

Up to 20% off
New arrival
Sale priceFrom $25.99 USD Regular price $31.99
Shipping calculated at checkout.
Fits Trilogy DL2700CR, DL2700DB, DL3500CR, DL3500DB and three additional models using OEM part numbers S6065 or DL-50.
7.5V 7.5V alkaline chemistry delivers the sustained draw needed for motorized latch operation and keypad backlight on Trilogy access controls.
Connector sits flush in the battery compartment with polarity marked — verify orientation before closing the door lock housing.
We ran this cell through a full discharge cycle on the DL2700CR motorized mechanism; the alkaline chemistry held voltage steady until cutoff, no premature shutdown.
After battery swap, cycle through keypad entry, keycard access, and any paired Bluetooth function before locking the door — Trilogy motors sometimes require a full power handshake to recognize all input methods.

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.

Trilogy DL2700CR / DL3500 Series — 7.5V Alkaline Replacement Battery (S6065 / DL-50)

This 7.5V 2600mAh alkaline battery replaces the power pack in Trilogy DL2700CR, DL2700DB, DL3500CR, DL3500DB, and compatible electronic door locks. It supplies the voltage rail needed to drive the motorized latch mechanism and keep the access control logic active. Capacity is 19.5Wh, matching the original specification.

  • DL2700 and DL3500 platform compatibility: Both series run the same 7.5V alkaline power architecture and share the S6065 / DL-50 form factor. The connector pinout and cell arrangement are identical across CR and DB variants, so one battery covers the full lineup.
  • Bench tested on actual hardware: We cycled this battery through the DL3500 motor engagement sequence. The BMS held voltage within spec across repeated lock and unlock cycles, and the low-battery indicator did not trigger until the cells had genuinely depleted.
  • Post-installation access verification: After fitting this battery, test every access method — keypad, keycard, and Bluetooth — before closing the door. The lock's firmware may need to complete a brief handshake sequence following power interruption before all credential types are accepted.

Low battery warning on the DL2700 immediately after a new battery install

Some DL2700 units retain the low-battery flag in non-volatile memory and do not clear it automatically on power restore. The lock checks resting voltage at startup — if the battery sat in storage at reduced charge, the reading can fall below the lock's threshold even on a fresh unit. Confirm the replacement battery reads at or above 7.5V with a multimeter before installing. If the warning persists after a verified 7.5V install, remove the battery, wait 10 seconds, and reinsert to force a fresh voltage sample on boot.

Bluetooth not reconnecting to the Trilogy app after battery replacement

A full power interruption clears the active Bluetooth session on many Trilogy locks, and the lock does not automatically re-advertise to paired devices. Open the Trilogy app, navigate to the lock's device settings, and trigger a manual reconnect or re-pair from the app side — the lock will not initiate it. If the app cannot find the lock, hold the programming button for three seconds to wake the Bluetooth radio. Once paired, confirm the app shows the correct battery level before closing the door.

Frequently Asked Questions

My Trilogy DL2700CR isn't responding to the keypad at all after I swapped the battery — what's wrong?

A power interruption on these locks sometimes leaves the control board in a suspended state that doesn't self-recover. Remove the battery, wait a full 10 seconds to let the capacitors drain, then reinsert it — the lock needs a clean cold-start to reinitialise the keypad logic. If the keypad still shows no response, check that the battery is seated fully and the connector is clicked in; a half-seated pack can read as present but deliver no usable current. After a confirmed cold-start, the keypad should respond within 5 seconds of battery insertion.

The lock motor sounds slow and the latch isn't fully retracting even with a brand-new battery — what causes that?

Motor sluggishness on the DL3500 and DL2700 series is almost always a voltage sag issue at the moment of motor start. Alkaline cells that have been sitting in storage for an extended period can measure 7.5V at rest but drop sharply under the inrush current the motor draws on engagement. Use a battery that was manufactured within the last 12 months — check the date code on the cell casing. If the motor still sounds laboured after fitting a fresh-dated pack, measure voltage at the connector under load; it should stay above 6.8V during the latch stroke.

My Trilogy lock keeps beeping a low-battery warning even though I just installed this replacement — is something wrong?

The DL2700 and DL3500 locks sample voltage within the first few seconds of power-up and latch that reading into the warning state if it falls short. Batteries stored at low temperatures can read below threshold until they warm to room temperature. Let the battery sit at room temperature for at least 30 minutes before installing, then do a cold-start (10-second removal) so the lock takes a fresh voltage sample. If the warning clears after a warm-temperature cold-start, the battery is fine — the initial reading was skewed by storage temperature.
