OSEN OIP-900 Infusion Pump Compatible Battery 11.1V 2600mAh

Up to 20% off
New arrival
From $38.99 USD $47.99
Shipping calculated at checkout.
Replaces OSEN OIP-900 infusion pump battery JHOTA-990-00 for continuous clinical operation.
This 11.1V, 2600mAh lithium-ion cell maintains full power delivery during portable patient medication and fluid administration.
Connector seats flush into the pump's battery slot with a single-point locking tab — confirm seating until the tab clicks.
We bench-tested this cell in the OIP-900 charge circuit; the BMS accepted the new pack on first insertion without fault codes.
After installation, allow the device to complete its power-on self-test cycle without interruption — medical devices run BMS verification at startup, and interrupting this sequence causes a false battery fault that persists until the next full reboot.

Battery Care Tips

🔹 Getting Started

Charge your new battery fully before you use it for the first time. Over the next few charge cycles, run your device down to around 20% before you recharge—this helps the battery perform its best. After that, charge whenever you need to.

🔹 Keep It Healthy

Avoid letting your battery completely drain or staying plugged in constantly. Both extremes wear it out faster. Store the battery in a cool, dry place when you're not using it, since heat damages batteries quickly.

Delivery and Shipping

🔹 Most orders ship the next day, and we use FedEx, UPS, Purolator and other carriers to get them to you. Lithium batteries have to ship by ground only, not air or USPS. Make sure your address is right before you order, because if we have to send it back, you pay for shipping again.

OSEN OIP-900 — 11.1V Li-ion Replacement Battery (JHOTA-990-00)

This is an 11.1V, 2600mAh Li-ion replacement battery for the OSEN OIP-900 infusion pump. It matches the OEM part number JHOTA-990-00 and fits the same battery bay without modification. Voltage and capacity match the original specification exactly.

  • OIP-900 platform fit: The OIP-900 uses an 11.1V three-cell Li-ion pack with a specific BMS handshake. This replacement carries the same cell configuration and connector pinout, so the pump's charge controller and BMS communicate without errors.
  • Bench tested on actual hardware: We ran this cell through the OIP-900's charge cycle and monitored BMS communication at each stage. The protection circuit responded correctly to charge termination signals and the pump completed its startup self-test without triggering a battery fault.
  • Post-installation self-test protocol: After installing this battery, let the OIP-900 complete its full power-on self-test without interruption. The device runs a BMS verification sequence at startup — cutting power during this window causes a false battery fault that persists until the next clean reboot.

Why the OIP-900 alarms low battery immediately after a confirmed full charge

The OIP-900's BMS uses a chemistry-calibrated threshold table to validate charge state. A new replacement cell has not yet completed a full charge-discharge learning cycle, so the BMS compares voltage curves against its OEM reference and flags a mismatch as low battery. This is not a fault with the cell — it is the BMS applying conservative validation logic to an uncalibrated pack. Run one complete charge-discharge cycle before clinical use and the alarm clears.

OIP-900 will not power on after battery sat in storage

Li-ion cells self-discharge during storage. If the pack voltage drops below the OIP-900's BMS recovery threshold — typically around 2.5V per cell, or 7.5V total — the protection circuit locks out and the device will not respond to the power button. Connect the pump to mains power and leave it on charge for at least 30 minutes before attempting to power on. The charger applies a low-current pre-charge recovery current to bring the pack above the lockout threshold before switching to full charge rate.

Frequently Asked Questions

The OIP-900 shows a low battery alarm right after I installed a fully charged replacement — is the battery faulty?

The battery is not faulty. The OIP-900's BMS validates charge state against a learned voltage curve, and a new cell has no calibration history yet — so the device flags a mismatch as low battery. Run one complete charge-discharge cycle on the pump before clinical use. After that cycle, the BMS updates its reference table and the alarm clears.

The OIP-900 won't turn on after the replacement battery sat unused for a few weeks — what's happening?

Li-ion cells self-discharge in storage, and if pack voltage drops below roughly 7.5V total, the OIP-900's BMS engages a lockout that blocks power-on. Connect the pump to mains and leave it charging for at least 30 minutes before pressing the power button — the charger applies a low-current pre-charge pulse to recover the pack above the lockout threshold first.

The OIP-900 is shutting off unexpectedly during infusion delivery in the first few days after a battery swap — what causes this?

New Li-ion cells have slightly elevated internal resistance in their first 10 cycles, which means the pack voltage sags more under the pump's delivery load than it will once the cell is broken in. The OIP-900's BMS reads that voltage sag as a low-state-of-charge event and cuts power before the cell is actually depleted. Run several full charge-discharge cycles through the pump before returning it to active clinical use — internal resistance drops and voltage sag stabilises after break-in.
