HandHeld Dolphin 6100 Replacement Battery BP06-00028A 3.7V

HandHeld Dolphin 6100 / 6110 — 3.7V Li-ion Replacement Battery (BP06-00028A)

This is a 3.7V 2200mAh Li-ion replacement battery for the HandHeld Dolphin 6100 and Dolphin 6110 mobile computers. It matches OEM part numbers BP06-00028A and 6000-TESC. These handheld scanners are common in retail pick-and-pack, warehouse inventory, and asset tracking environments where the battery takes sustained daily abuse.

• Dolphin 6100 and 6110 compatibility: Both models share the same 3.7V single-cell architecture, battery bay dimensions, and BMS handshake protocol — the same pack runs across both without modification or adapter.
• Bench tested on actual hardware: We ran this pack through scan-trigger inrush cycling and wireless polling loads. The BMS held regulation without nuisance trips across repeated burst-scanning sequences at full radio activity.
• First-shift cradle charge: After installing the new pack, seat it in the charging cradle and let it complete a full charge cycle before starting a shift. Scan-trigger inrush current peaks when the cell is near minimum voltage — a fully charged cell prevents false BMS cutoffs during that first heavy-use period.

Why the Dolphin 6100 drops wireless connection during rapid scan bursts

The Dolphin 6100 draws from a single cell powering both the imager and the 802.11 radio simultaneously. During rapid burst scanning, the combined inrush from the scan trigger and the radio transmit pulse can spike current draw beyond what a degraded or partially charged cell can supply. The BMS interprets this as an overcurrent condition and momentarily cuts output, which the radio stack reads as a power loss — dropping the connection. A fresh, fully charged pack at 4.2V absorbs these spikes without the BMS intervening.

Cradle shows a charging error after fitting the new pack

Charging errors on the Dolphin cradle after a battery swap are almost always a contact resistance issue, not a pack fault. The cradle's charge contacts are gold-plated pads that accumulate oxidation and debris from warehouse environments. Wipe the battery contacts and the cradle contacts with a dry lint-free cloth, then reseat the pack firmly until it clicks. If the error clears within 30 seconds of reseating, the contacts were the cause — the pack is fine.
