Battery Care Tips
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
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.

DOTLUX NOTSTROM AKKU-KIT — 6.4V LiFePO4 Replacement Battery (5938)
This is a 6.4V 3000mAh LiFePO4 replacement cell for the DOTLUX NOTSTROM AKKU-KIT emergency lighting system. It fits the AKKU-KIT, 5556, and 4343-2 models. Voltage and chemistry match the OEM specification exactly, keeping the charge controller in its normal operating window.
- AKKU-KIT, 5556 and 4343-2 compatibility: All three fittings share the same 6.4V LiFePO4 charge rail and connector footprint. The BMS in each unit expects LiFePO4 float voltage — swapping to Li-ion chemistry would push the charge controller out of range and trigger a permanent fault LED.
- Bench tested on actual hardware: We ran this cell through a full charge-discharge cycle on the AKKU-KIT charge circuit. The BMS accepted the cell without a fault event, and the charge indicator advanced to green within the expected absorption window.
- First test cycle after installation: Within 24 hours of fitting, hold the test button for the full rated duration. This confirms the new cell accepts load under emergency conditions and lets the charge controller register actual cell capacity before the next scheduled compliance test.
Emergency light failing its duration test after battery replacement
A freshly installed LiFePO4 cell ships with a partial state of charge — typically 40–60% — from storage. If a duration test runs before a full charge cycle completes, the cell will exhaust early and the fitting will fail compliance. LiFePO4 cells also require one complete charge-discharge cycle before they reach rated capacity. Allow at least 24 hours on mains charge after installation, then run a full test cycle before logging a compliance result.
Charge indicator staying red after new battery installation
Extended storage can pull a LiFePO4 cell below the charge controller's float acceptance window — usually around 5.5V for a 6.4V pack. When the cell arrives below that threshold, the controller sees the voltage as out-of-range and holds the fault state rather than beginning a charge cycle. Connect the fitting to mains and leave it undisturbed for two to four hours; the controller will trickle-charge the cell up through the acceptance threshold and then switch to normal absorption charge. If the indicator does not advance to green after four hours, measure cell voltage directly — anything below 5.0V indicates a cell that did not recover from deep discharge.

Frequently Asked Questions
The emergency light passed its last test but failed the duration test right after I fitted the new battery — why?
A replacement LiFePO4 cell ships at partial charge, typically 40–60% capacity. Running a duration test before the cell reaches full charge means it exhausts before the rated period ends. Leave the fitting on mains for a full 24-hour charge cycle after installation, then run the test — the cell needs at least one complete charge cycle to deliver its rated 3000mAh.
The light comes on during a mains-failure test but dims noticeably after a few minutes — is the cell faulty?
Not necessarily. A new LiFePO4 cell that has not completed a full conditioning cycle will show early voltage sag under sustained load, which the fitting interprets as low battery and reduces output. This is a state-of-charge issue, not a cell defect. Recharge fully for 24 hours, run one complete test cycle to condition the cell, and retest — output should hold steady for the full rated duration.
The fitting still shows a fault LED after I confirmed the new battery is seated correctly — how do I clear it?
Some DOTLUX fittings latch the fault LED in firmware and do not auto-clear when a new cell is detected. Disconnect the fitting from mains, wait 30 seconds to allow the charge controller to reset, then reconnect. If the LED persists, press and hold the test button for 10 seconds with mains connected — this forces a controller re-initialisation cycle and clears the latched fault on most AKKU-KIT variants.
