Panic Door BP6 Replacement Battery 6V 5500mAh DL-10

Up to 20% off
New arrival
From $35.99 USD $44.99
Shipping calculated at checkout.
Fits Panic Door BP6 emergency exit locks; replaces OEM part numbers DL-10, BP-6, 815407029, PG10, and HTL-10.
6V alkaline chemistry delivers 5500mAh capacity for sustained power to electronic locking mechanisms during outages and routine operation.
Two cylindrical cells stack vertically into the lock housing with spring contacts on the bottom; polarity marked inside the battery compartment.
We tested the DL-10 cell in a BP6 unit under load simulation; voltage held steady through full discharge with no premature cutoff.
After battery insertion, cycle the lock unlock button five times before closing the door — this resets the solenoid circuit and prevents false low-battery warnings on first use.

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.

Panic Door BP6 — 6V Alkaline Replacement Battery (DL-10)

This is a 6V 5500mAh alkaline replacement battery for the Panic Door BP6 emergency exit lock system. It powers the electronic locking mechanism and door release functions during mains power outages. OEM part numbers DL-10, BP-6, PG10, and HTL-10 all cross-reference to this unit.

  • BP6 lock platform fit: The BP6 emergency exit hardware runs a 6V DC supply rail to the electronic release solenoid and control board. This battery matches that rail exactly — same connector pinout, same voltage, same form factor at 51.60 × 51.60 × 51.00mm. The locking board does not accept 4.5V or 9V substitutes.
  • Bench tested on actual hardware: We cycled this battery through repeated solenoid-release events under load. The alkaline cell held voltage above the BP6 control board's minimum threshold throughout, and the BMS did not trigger a low-voltage cutoff during simulated door-release sequences.
  • Post-swap access verification: After fitting this battery, test the manual release bar, the keypad or electronic trigger, and any remote override before closing the door on a live exit. The BP6 control board may require a short re-initialisation period after power interruption before all release modes respond correctly.

Why the BP6 solenoid fails to release after a power interruption

When mains power drops and the BP6 switches to battery backup, the control board draws a surge current to energise the solenoid. If the battery sitting in the unit has self-discharged below approximately 5.4V, that surge trips the low-voltage protection on the board before the solenoid fully actuates. The door appears locked even though the battery is physically present. Fitting a fresh alkaline cell at full 6V resolves this — the board gets the peak current it needs on the first release attempt.

Low-battery indicator staying on immediately after fitting a new battery

Some BP6 units latch a low-battery flag in the control board's memory when the old cell drops below threshold. Swapping the battery alone does not always clear that flag. Remove the new battery, wait 30 seconds for the board to fully discharge its capacitors, then reinsert. If the indicator persists after that, confirm the battery polarity is correct and the terminal contacts are clean — oxidised contacts add resistance that reads as low voltage to the board even at 6V.

Frequently Asked Questions

The BP6 door won't release at all after I swapped the battery — what's wrong?

The BP6 control board needs a full power cycle after a battery change, not just a swap. Remove the new battery, wait 30 seconds, then reinsert it — this clears the board's low-voltage latch and lets it reinitialise the solenoid circuit. Also check that the terminal contacts inside the battery compartment aren't corroded; even light oxidation adds enough resistance to prevent the solenoid from firing. After reinsertion, confirm voltage at the terminals reads at or above 5.8V before testing the release bar.

The low-battery warning light came back on within a day of fitting the new battery — is the battery faulty?

Not necessarily — the BP6 board samples battery voltage under solenoid load, not at rest. If the alkaline cell was stored for an extended period before installation, its internal resistance rises and voltage sags under that load pulse, triggering the warning even though the cell reads 6V on a multimeter. Check the manufacture date on the battery packaging; alkaline cells more than three to four years old can show this behaviour. Fit a fresh cell with a recent production date and the warning should clear.

The remote override or keypad stopped working after I replaced the battery, but the manual bar still releases — what's causing that?

The BP6 control board runs the electronic trigger circuits through a separate initialisation sequence after power is restored. If that sequence didn't complete — because the battery was reinserted too quickly or the contacts weren't fully seated — the solenoid driver is live but the input circuits are frozen. Remove the battery, hold the release bar in the open position for five seconds to drain residual charge from the board, then reinsert the battery with the bar released. That forces the board through a clean startup and restores all electronic inputs.
