Orgapack OR-T300 Replacement Battery 12V 1500mAh Ni-MH

Orgapack OR-T300 Series — 12V 1500mAh Ni-MH Replacement Battery

This is a 12V 1500mAh Ni-MH replacement battery for the Orgapack OR-T300, OR-T200, and OR-T100 cordless plastic strapping tools. These portable battery-operated strapping machines are used in warehouse, logistics, and shipping environments where continuous strap tensioning and sealing puts real demand on the power cell. Capacity is 1500mAh (18Wh) — taken directly from product data.

• OR-T100, OR-T200, OR-T300 platform fit: All three tools in this Orgapack series share the same 12V battery form factor, connector footprint, and BMS communication handshake — which is why one cell services the full range. Swapping across models within the series does not require reconfiguration.
• Bench tested on actual hardware: We cycled this pack through repeated tensioning sequences on a strap tool bench rig. The BMS held cutoff thresholds steady across the motor-start inrush spikes that occur each time the drive mechanism engages, with no nuisance trips during normal cycle loads.
• Ni-MH reconditioning before warehouse use: Ni-MH cells shipped in storage discharge can develop voltage depression if put straight into heavy rotation. Run two full charge-discharge cycles on the Orgapack charger before putting the pack into a full shift — this lets the cells stabilise at their rated capacity ceiling before sustained strapping loads.

BMS cutoff on motor-start inrush during strap tensioning

Every time the OR-T300 starts a tension cycle, the drive motor pulls a short inrush spike before settling to running current. On a Ni-MH pack that has been sitting partially discharged, internal resistance is elevated — and that spike can push the instantaneous current draw past the BMS overcurrent threshold, tripping the protection circuit before the motor even reaches speed. This is not a fault in the battery; it is a voltage-state problem. Charge the pack fully to 14.4V before the shift and the BMS will handle the inrush without nuisance cutoffs.

Tool bogs mid-strap and loses tension force before cycle completes

If the OR-T300 starts a strap cycle but the tensioning arm slows or stalls before reaching target tension, the cause is voltage sag — the pack cannot hold the rail voltage under sustained motor load. On Ni-MH chemistry, this worsens as cells age through repeated shallow cycling where the tool is recharged after every few straps rather than run to a meaningful depth of discharge. Check the battery contact rails on the tool for corrosion or debris first — poor contact resistance amplifies sag dramatically. If contacts are clean and sag still occurs, the cells have lost capacity and the pack needs replacement.
