About this replacement
Honeywell CT30 XP / CT30 XP HC — 3.87V Li-ion Replacement Battery (CT30P-BTSC-001)
This 3.87V, 3350mAh (12.96Wh) lithium-ion battery replaces the CT30P-BTSC-001 and CT30P-BTSC-002 OEM packs. It fits both the Honeywell CT30 XP and CT30 XP HC mobile computers — the same cell form factor and BMS handshake protocol covers both variants. Swap it out when your scanner starts dying partway through a shift.
- CT30 XP and CT30 XP HC compatibility: Both models run the same 3.87V battery rail, use the same physical connector, and expect the same BMS communication. One replacement pack covers both variants without firmware differences or adapter changes.
- Bench tested on actual hardware: We cycled this pack through simulated scan-burst loads — alternating imager trigger pulls and active wireless polling — and confirmed the BMS held voltage without false low-cell trips or thermal flags across the full discharge curve.
- First-shift install tip: After installing, dock the scanner for a complete charge cycle before putting it into pick-and-pack rotation. Scan trigger inrush current peaks when the cell is near minimum charge, and a pre-charged pack prevents the BMS from tripping on the first heavy burst of the shift.
Cradle showing a charging error on a new CT30 XP pack
The CT30 XP charging cradle checks BMS communication through the battery contact pins before it starts a charge cycle. If those contacts have any residue — oil from handling, warehouse dust, or oxidation from a previous pack — the dock reads a handshake failure and throws a charging error. The fix is almost always mechanical, not a faulty battery. Wipe the gold contacts on both the battery and the cradle dock with a dry lint-free cloth, reseat the scanner firmly, and check that the charging LED turns solid within 10 seconds.
Scanner not reading barcodes after a battery swap
The CT30 XP imager requires a stable voltage above the minimum operating threshold before the scan engine will fire. If you swap in a partially discharged replacement pack, the first trigger pull can pull voltage below that floor and the scanner returns a blank read — not a scan failure, just insufficient power. This is commonly mistaken for a faulty battery or a broken imager. Dock the unit for a full charge cycle first, then test the scan trigger — imager response should be immediate at full charge.
