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.

Carrousel RDB — 28.8V Ni-MH Replacement Battery (80100701)
This is a 28.8V, 2000mAh Ni-MH battery for the Carrousel RDB automatic door operator. It replaces OEM part 80100701 and fits the door controller's backup power circuit directly. When mains power drops, this battery keeps the door completing full open and close cycles without interruption.
- Carrousel RDB backup power circuit: The RDB operator relies on a 28.8V Ni-MH pack to match the door controller's voltage rail. The BMS on this pack communicates with the door's charge management board — swapping chemistry or voltage trips a fault state and disables backup mode entirely.
- Bench tested on actual hardware: We cycled this pack through repeated power-fail simulations on the RDB platform. The BMS held charge delivery stable across full open-and-close cycles under motor load, and the controller recognised the pack without a fault flag on each run.
- Post-installation power-fail test: After fitting this battery, manually trigger a mains-fail test during a low-traffic period. Automatic door backup batteries must complete at least one full door cycle under load at installation — waiting until an actual outage to verify backup function is a compliance risk.
Automatic door not completing a full open cycle on battery backup
When the RDB operator runs on backup, it draws a surge of current at motor start. A partially depleted Ni-MH pack drops voltage sharply under that load, triggering the BMS to cut power mid-cycle. The door stalls partway open — not because the motor has failed, but because the battery pack cannot sustain the voltage rail above the controller's cutoff threshold. The fix is a fully charged pack: Ni-MH cells need a full 24-hour charge before a load test is valid.
Door controller loses its programming after a power outage
The RDB controller stores door settings — open speed, hold time, obstacle sensitivity — in volatile RAM. That RAM is backed continuously by the 28.8V battery pack, not by a separate coin cell. When the pack depletes fully, even a brief mains failure wipes the configuration. If the door reverts to default behaviour after every outage, the backup battery has failed rather than the controller board itself. Replace the pack and reprogram the door settings; verify the new pack reads above 28V on a multimeter before reinstalling.

Frequently Asked Questions
The door starts to open during a power cut but stops halfway — what's causing it?
A Ni-MH pack that hasn't been fully charged can't sustain the voltage spike the RDB motor draws at the start of each cycle. The BMS hits its cutoff threshold under load and interrupts power before the door completes travel. This isn't a motor fault — it's voltage sag from a partially charged or aged pack. Charge the new battery for a full 24 hours, then run a manual power-fail test to confirm it completes a full open-and-close cycle.
My Carrousel RDB door has lost all its settings — open speed, hold time, everything reset to default — after the power went out. Is the controller board faulty?
Almost certainly not. The RDB controller stores its configuration in volatile RAM, and that RAM is kept alive by the 28.8V backup battery pack, not by a separate internal cell. When the pack depletes fully, even a short mains interruption is enough to wipe all stored settings. Replace the backup battery, confirm it reads above 28V with a multimeter, reinstall it, then reprogram the door parameters through the controller interface.
The door moves noticeably slower than usual whenever it runs on battery backup — is something wrong?
This is normal behaviour on the Carrousel RDB. The controller deliberately reduces motor drive speed when operating on battery backup to spread the load across the available charge and complete the door cycle. If the slow movement only occurs during mains failure and full speed returns when power is restored, the system is working as intended. If slow movement persists on mains power, check whether the door has inadvertently entered a fault or service mode rather than suspecting the battery.
