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.

Autoslide MultiDrive Series — 21.6V Li-ion Replacement Battery (AS0114LBB)
This 21.6V 3400mAh Li-ion battery replaces part AS0114LBB in Autoslide MultiDrive and MultiDrive Sliding automatic door operators. It powers both the control electronics and drive motor during mains failure, keeping the door operational for emergency egress and accessibility compliance. Voltage and capacity match the OEM specification exactly.
- MultiDrive and MultiDrive Sliding compatibility: Both variants run the same 21.6V battery rail and share the AS0114LBB connector and BMS handshake. One battery covers the full range without any modification.
- Bench tested on actual hardware: We cycled this battery through full mains-fail simulations on the MultiDrive controller. The BMS held stable voltage across repeated open-close cycles and did not trigger an early low-voltage cutoff under motor-start load.
- Post-install power-fail verification: After fitting, manually trigger a mains-fail test during a low-traffic period. Automatic door backup batteries must complete a full door cycle under real motor load — a resting voltage check alone will not confirm the battery is serviceable.
Battery backup not activating during mains failure on the MultiDrive
The MultiDrive backup circuit only engages when the battery holds sufficient charge for the controller to confirm it can complete at least one full cycle. If the battery has sat unused for an extended period, self-discharge can drop cell voltage below the controller's activation threshold — even if the battery was healthy when last tested. The backup relay will not close, and the door behaves as if no battery is fitted. Charge the replacement battery for a full 24 hours before testing, then run a manual mains-fail cycle to confirm activation.
MultiDrive controller losing door programming after a power outage
The MultiDrive stores door travel limits, speed profiles, and sensor calibration in volatile memory backed by this battery. When the battery depletes fully, that memory loses power — even briefly — and the controller resets to factory defaults on the next mains restore. The door may then fail to complete its open or close stroke because travel limits are gone. After fitting a charged replacement, re-run the auto-setup or manual limit-programming sequence before returning the door to service.

Frequently Asked Questions
My MultiDrive door starts to open on battery backup but stops halfway through the cycle — what's wrong?
The controller monitors voltage during the motor-start surge and will abort the cycle if the battery sags below its cutoff threshold mid-stroke. This usually means the battery isn't at full charge — a partially charged cell can pass a resting voltage check but collapse under motor load. Charge the new battery for a full 24 hours before running a mains-fail test. If it still stops mid-cycle, check the door mechanics for binding, which increases motor draw and causes premature BMS cutoff.
The door moves noticeably slower than normal when running on battery backup — is something wrong with the battery?
No — this is intentional. The MultiDrive controller reduces motor speed when operating on battery to limit current draw and extend the number of cycles available before the battery depletes. Slow movement on backup is a firmware behaviour, not a sign of a faulty or undersized battery. If the door is also struggling to reach the end stops or reversing unexpectedly, check the travel limit settings, which may have reset if the battery previously went flat.
The MultiDrive backup battery was replaced six months ago but failed to activate during a recent power cut — how does that happen?
Li-ion cells self-discharge even when idle, and the MultiDrive backup circuit requires the battery to be above a minimum voltage before the relay will engage. Six months of inactivity without a top-up charge can push the pack below that threshold. The fix is to re-charge the battery for 24 hours, then run a manual mains-fail test to confirm the backup circuit closes correctly. Schedule a mains-fail test every three months to catch voltage drop before an actual outage.
