Denso BHT-2065 Replacement Battery 4.8V 900mAh Ni-MH

Denso BHT-2065 / BHT-700 / BHT-2000 — 4.8V Ni-MH Replacement Battery (496466-0240)

This is a 4.8V, 900mAh Ni-MH replacement battery for the Denso BHT-2065, BHT-700, and BHT-2000 portable data collection terminals. These scanners are used in retail, warehousing, and logistics for barcode scanning and inventory tracking. It replaces OEM part number 496466-0240 directly.

• BHT-2065, BHT-700, and BHT-2000 compatibility: All three models run on the same 4.8V NiMH cell pack with the same physical form factor and connector orientation. The BMS handshake and charge termination behaviour is identical across the series, so one pack covers the full range.
• Bench tested on actual hardware: We cycled this pack through repeated scan-and-transmit sequences on the bench. The BMS held stable under the combined inrush of the scan trigger and wireless radio, with no false cutoff events at any state of charge above the minimum threshold.
• First-shift charge protocol: After installing this pack, seat the scanner in its cradle and run a full charge cycle before the first pick-and-pack shift. The scan trigger inrush current spikes hardest when the cell is near minimum — a fully charged cell on day one prevents the BMS from tripping on the first scan burst of the shift.

Cradle showing a charging error on a brand-new pack

NiMH packs ship in a partially discharged state to stabilise cell chemistry during transit. Some Denso cradles read this low starting voltage as a fault condition and throw a charging error rather than entering a normal charge cycle. The fix is to seat and reseat the pack twice, wiping the gold contacts on both the battery and cradle with a dry cloth first. Contact resistance above roughly 0.1 ohm is enough to trigger the fault — clean contacts resolve it in most cases without any further action.

Scanner losing wireless connection during rapid scan bursts

During a fast scan burst, the BHT series draws current simultaneously from the scan engine and the wireless radio. On a degraded or deeply discharged cell, this combined load causes a brief voltage sag that drops below the radio module's minimum operating threshold — the wireless link drops before the battery protection circuit even activates. This is not a firmware issue or a pairing problem. Charge the pack to full before the shift and confirm the resting voltage is at or above 4.6V before docking the unit in a high-throughput scan zone.
