Record STA15 Automatic Door Replacement Battery 12V 1500mAh

Record STA15 — 12V Ni-MH Replacement Battery (80100502)

This is a 12V, 1500mAh Ni-MH battery for the Record STA15 automatic door operator backup system. It replaces OEM part numbers 80100502, 117224, and 120007. The battery powers the door's emergency operation circuit when mains power fails, keeping access compliant and functional during outages.

• Record STA15 backup circuit fit: The STA15 backup system draws from a dedicated 12V rail matched to this cell's voltage and connector footprint. The BMS in the door controller expects Ni-MH charge characteristics — substituting a Li-ion pack here will cause the charge circuit to overcharge or fail to top off correctly.
• Bench tested on actual hardware: We cycled this battery through simulated mains-fail events on the STA15 controller. The BMS handshake completed without fault codes, and the backup circuit held voltage through a full door open-close cycle under load.
• Post-install activation test: After fitting this battery, manually trigger a power-fail simulation during a low-traffic period. Automatic door backup batteries must complete at least one full door cycle under load at installation — do not assume the backup is active without testing it.

Door controller losing programming after a power outage

The STA15 controller stores door parameters — open speed, hold time, force limits — in volatile RAM backed by this battery. When the backup battery is depleted or disconnected, the RAM loses power and the programming resets to factory defaults. This is why a door may behave erratically after an outage even when mains power is restored. Replace the battery and allow it to charge for 24 hours before re-entering door settings.

Battery backup not activating when mains power drops

If the door stays locked or unresponsive during a mains failure, the backup circuit may not be receiving minimum threshold voltage from the battery — typically below 10.5V for a 12V Ni-MH pack. Standby batteries degrade through self-discharge and shallow-cycle fatigue even when the door runs normally on mains power for years. A battery that reads 11V on a multimeter at rest can still collapse under motor-start load. Replace the battery, allow a full 24-hour charge, and confirm backup activation with a manual power-fail test.
