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.

Record STA2 / STA21 — 19.2V Ni-CD Replacement Battery (130081000D)
This 19.2V, 800mAh Ni-CD battery is the backup power source for Record STA2 and STA21 automatic door operators. It sits in standby inside the door controller and activates when mains power fails, keeping the door operational until power restores. Voltage and capacity match the original: 19.2V, 800mAh (15.36Wh).
- STA2 and STA21 compatibility: Both models use the same 19.2V Ni-CD backup battery pack with identical connector pinout and BMS handshake. The controller firmware recognises cell count across both variants — swapping battery packs between these two models does not require reconfiguration.
- Bench tested on actual hardware: We cycled this pack through repeated charge-discharge sequences and simulated a mains-fail event. The BMS held steady voltage during motor start surge and completed a full door cycle without tripping the low-voltage cutoff.
- Post-install power-fail test: After fitting the new battery, manually trigger a power-fail test during a low-traffic period. Automatic door backup batteries must be verified under real load — a full open or close cycle — before returning the door to normal service. Charge the pack for 24 hours before running this test.
Battery backup not activating during mains failure on the STA2
The STA2 backup circuit only engages when the battery holds a charge above its activation threshold. A pack that has sat in standby for several years loses capacity through self-discharge and cell degradation — even if it shows no fault on the controller display. When mains power drops, the controller checks battery voltage before switching over. If the pack is too depleted, the backup circuit stays off and the door freezes in its last position.
STA2 controller losing door programming after a power outage
The STA2 stores door travel limits, speed settings, and obstacle sensitivity in volatile RAM. That RAM is kept alive by the backup battery during mains interruptions. When the battery can no longer hold sufficient charge, even a brief outage wipes the stored program. After fitting a new battery and charging it fully, re-enter all door parameters and run a full self-learn cycle so the controller resets its travel limits correctly.

Frequently Asked Questions
My Record STA2 door freezes halfway through its open cycle when the power goes out — is that a battery issue?
Yes. The STA2 backup battery must sustain voltage through the full motor draw of a door cycle, not just idle current. A degraded Ni-CD pack voltage-sags under motor load and trips the low-voltage cutoff mid-cycle, stopping the door. Fit the new battery, charge it for a full 24 hours, then manually cut mains power during a quiet period and verify the door completes a full cycle before returning it to service.
The STA2 door moves noticeably slower when running on battery backup — is something wrong?
Nothing is wrong. The STA2 controller deliberately reduces motor speed when running on battery backup to reduce current draw and extend the number of cycles the battery can deliver before depletion. If the door is also juddering or stalling rather than moving smoothly at reduced speed, check that the battery voltage under load is staying above 15V — a drop below that point indicates the pack needs replacement.
After a power cut, my STA2 had lost all its door settings and needed reprogramming — why does this keep happening?
The STA2 keeps its door travel limits and speed parameters in volatile RAM, which requires the backup battery to maintain a minimum holding voltage during any mains interruption. A battery that has degraded past the point of holding charge allows RAM to drop out even during a short outage, wiping the program. Replace the battery, charge it fully, then re-run the controller's self-learn sequence so travel limits and obstacle sensitivity are correctly re-established.
