Replacement for Brother LD0665001 and AP-1908

This two-pack supplies 3.7 V lithium-ion cells rated at 2300 mAh and 8.51 Wh each. They serve as direct replacements for the Brother LD0665001 MDS2E and AP-1908 batteries used in compatible document scanners.

Fits DS820W and DS920DW scanners

The pack fits the Brother DS820W and DS920DW models without modification. Built-in protection circuits guard against over-charge, over-discharge, over-voltage, over-current and over-heating so the scanner can operate continuously without an external power adapter.

Sustained scanning sessions

Under continuous feed workloads the cells maintain stable voltage through the protection circuitry. The 2300 mAh capacity supports extended batch scanning, and the safety certifications (UL1642 and CE) ensure reliable thermal behaviour during long duty cycles.
