4.8V, 4000mAh capacity delivers full-duration runtime for backup illumination during mains failure events.
Connector clips onto the B170/44 battery slot with positive and negative terminals oriented downward.
We bench-tested this cell on the B170/44 charge circuit; the BMS accepted load within two hours of initial insertion.
After installation, hold the test button for the full rated duration within 24 hours — this confirms the new cell accepts load and lets the charge controller register capacity before the next compliance test.

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.

ORBIK B170/44 — 4.8V Ni-CD Replacement Battery

This is a 4.8V, 4000mAh nickel-cadmium replacement battery for the ORBIK B170/44 emergency lighting unit. It slots into the existing fitting and restores the backup power that activates when mains power fails. Dimensions are 237.00 x 32.60 x 32.60mm — confirm clearance before ordering.

  • B170/44 fitment: The B170/44 uses a dedicated Ni-CD cell at 4.8V to match the charge controller's float voltage rail. Swapping to a different chemistry or voltage triggers a persistent fault state on the charge board.
  • Bench tested on actual hardware: We ran this cell through a full charge cycle and a simulated mains-drop activation. The BMS accepted charge without error, and the cell held voltage under load through the full rated test duration.
  • First installation test cycle: Within 24 hours of fitting, hold the test button for the full rated duration. This lets the charge controller register the new cell capacity and confirms the cell accepts load before your next scheduled compliance inspection.

Charge indicator staying red after new battery installation

Ni-CD cells lose voltage during storage. If the cell voltage on arrival sits outside the charge controller's float acceptance window, the controller flags a fault instead of entering normal charge mode. This is not a faulty battery or a faulty fitting. Leave the fitting powered for 12–24 hours — the controller will trickle-charge the cell up to the acceptance threshold and switch to green once voltage reaches approximately 5.4–5.6V across the pack.

Emergency light dims and cuts short during the duration test

A new cell installed without a conditioning cycle will not deliver its full 4000mAh on first activation. The charge controller hasn't yet logged a complete charge-discharge reference for the new cell, so available capacity is lower than rated. The fix is one full charge cycle before the test — at least 24 hours on mains with no activation. After that conditioning cycle, the cell will deliver rated capacity and the light will hold output for the full test duration.

Frequently Asked Questions

The emergency light passed its last test but failed the duration test right after I put this new battery in — did I get a dud cell?

Almost certainly not. A fresh Ni-CD cell ships in a partially discharged state and needs one full charge cycle before it can deliver its rated 4000mAh. Install the battery, leave the fitting on mains power for at least 24 hours without triggering a test, then run the duration test. One conditioning cycle is all it takes for the cell to reach rated capacity.

The fitting's fault LED is still on after I've double-checked the connections and confirmed the new battery is seated correctly — what's causing it?

Some ORBIK fittings latch a fault LED in hardware and won't clear it automatically after a battery swap. The cell voltage may also be reading low after storage, which keeps the controller in fault mode. Power the fitting off at the circuit breaker for 30 seconds, then restore mains — this forces a controller reset. If the LED clears but returns within an hour, leave the fitting powered for 12 hours to let the cell charge up past the float acceptance threshold before resetting again.

The battery casing looks swollen on the old cell I'm replacing — is that a fitting problem or just old age?

Swelling in Ni-CD cells in emergency lighting is almost always caused by years of continuous trickle charge at elevated temperature inside a closed fitting. The charge controller maintains a float charge 24 hours a day, and heat build-up inside the housing accelerates cell degradation. Before fitting the replacement, check that the fitting's ventilation slots are clear and unobstructed. If the fitting is mounted above a heat source or in a ceiling void with poor airflow, the replacement cell will face the same conditions — clear the airflow path first.
