Mindray T1 Patient Monitor Replacement Battery 7.4V 2600mAh

Up to 19% off
New arrival
From $53.99 USD $66.99
Shipping calculated at checkout.
Fits Mindray T1 patient monitor. Replaces OEM battery part numbers LI12I001A, 2ICR19/65, LI12I002A, and 115-018016-00.
7.4V 2600mAh lithium-ion cell delivers 19.24Wh to sustain continuous vital signs monitoring during transport and power loss events.
Connector slides straight into the T1 battery slot with a single locking tab engagement — orientation is keyed to prevent reverse insertion.
We bench-tested this cell in a Mindray T1 monitor. The BMS recognized the pack on first insertion and completed a full charge cycle without fault codes.
Allow the T1 to complete its power-on self-test cycle without interruption after battery installation — the device runs 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.

Mindray T1 / Beneview T1 — 7.4V Li-ion Replacement Battery (LI12I001A)

This 7.4V 2600mAh Li-ion battery replaces the OEM cell in the Mindray T1 and Beneview T1 portable patient monitors. It fits the compact transport monitors used for continuous vital signs monitoring — heart rate, SpO2, NIBP, and temperature. Cross-references include LI12I002A, 2ICR19/65, and 115-018016-00.

  • T1 and Beneview T1 platform fit: Both monitors share the same battery bay geometry, connector pinout, and BMS communication protocol. The T1's power management circuit queries the battery over the SMBus interface at boot — the cell must respond with correct chemistry flags or the device will flag a battery fault.
  • Bench tested on actual hardware: We ran this cell through the T1's full power-on self-test sequence. The BMS handshake completed on first boot, charge IC accepted the cell without fault codes, and the monitor transitioned to normal operating mode without manual intervention.
  • Post-swap startup protocol: After installing this battery, let the T1 complete its full power-on self-test cycle without interrupting it. The monitor runs a BMS verification routine at startup — cutting power during this sequence creates a battery fault flag that persists until the next clean reboot.

Why the T1 alarms low battery immediately after a confirmed full charge

The T1's BMS stores a chemistry calibration profile from the previous cell. A new cell with no discharge history has no accumulated cycle data, so the BMS applies a conservative capacity estimate at first boot. This causes the monitor to read state-of-charge lower than actual voltage supports. One full charge-discharge cycle lets the BMS recalibrate against the new cell's actual capacity curve, and the alarm clears on its own.

T1 not completing boot sequence after battery sat in storage

Li-ion cells self-discharge at roughly 2–3% per month. A cell stored for several months can drop below 3.0V per cell — the T1's BMS recovery threshold. Below this level, the BMS locks out discharge to protect the cell, and the monitor appears completely dead. Connect the T1 to mains power first and leave it for 20–30 minutes before attempting a boot — the charge IC applies a trickle pre-charge to bring the cell back above 3.0V per cell, after which normal charging and boot sequence resume.

Frequently Asked Questions

The T1 shows a low battery warning immediately after I installed a fully charged replacement — is the new cell defective?

The cell is not defective. The T1's BMS has no cycle history for the new cell and defaults to a conservative state-of-charge estimate, which triggers the threshold alarm even when voltage is normal. Run one complete charge-discharge cycle on the T1 — the BMS recalibrates against the actual capacity curve and the warning clears. Do not deploy the battery for clinical use until that first full cycle is complete.

The T1 powers off unexpectedly during patient monitoring even though the battery indicator showed adequate charge — what causes this?

New Li-ion cells show elevated internal resistance in the first 5–10 cycles. Under the T1's clinical load profile — continuous SpO2, NIBP cycling, and display — voltage sag across that resistance can momentarily drop below the BMS cutoff threshold even when resting voltage looks adequate. The BMS interprets this as cell depletion and shuts the device down. Complete 5 to 10 full charge-discharge cycles to condition the cell; internal resistance drops and voltage sag under load decreases to stable levels.

My T1 won't power on at all after the replacement battery was left uninstalled for several months — how do I recover it?

Extended storage allows self-discharge past the T1's BMS recovery threshold of approximately 3.0V per cell. Below that level the BMS blocks discharge entirely, so the monitor shows no response on the power button. Install the battery and connect the T1 to mains AC power — do not press the power button yet. Leave it on charge for 20 to 30 minutes to allow the charge IC to trickle pre-charge the cell back above 3.0V per cell, then attempt a normal boot.
