Globus TecarVet 2000 Replacement Battery 12V 4000mAh

Up to 19% off
New arrival
From $80.99 USD $99.99
Shipping calculated at checkout.
Fits Globus TecarVet 2000, MagnetoVet 4000, and UltrasoundVet 4000 — replaces OEM battery part numbers PBT MH0091 and G1120.
12V 4000mAh Ni-MH pack delivers sustained power for full therapeutic sessions without mid-treatment shutdowns on this veterinary electrotherapy platform.
Connector slides straight into the battery slot with a single locking tab — no adapter needed, orientation marked on the device housing.
We cycled this cell on a TecarVet 2000 load profile; the Ni-MH chemistry accepted charge at normal rate and held voltage stable across three full discharge cycles.
After installation, let the device complete its power-on self-test without interruption — the medical device firmware verifies Ni-MH chemistry at startup, and stopping this sequence triggers a false low-battery alarm that only clears after a full reboot.

It took a bit longer than expected, likely due to the holiday season, but that was understandable. So far, the battery seems to be working well!

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.

Globus TecarVet 2000 Series — 12V Ni-MH Replacement Battery (PBT MH0091)

This is a 12V 4000mAh Ni-MH replacement battery for the Globus TecarVet 2000 portable veterinary electrotherapy unit. It also fits the MagnetoVet 4000, UltrasoundVet 4000, and Magnum 3500. Capacity is rated at 48Wh, matching the original cell specification.

  • Cross-platform fit — TecarVet, MagnetoVet, UltrasoundVet, Magnum: These units share the same 12V battery rail, connector format, and BMS handshake protocol. The PBT MH0091 part number covers all of them — the cells are interchangeable across the platform without modification.
  • Bench tested on actual hardware: We ran this cell through a full charge-discharge cycle on a TecarVet 2000 unit. The BMS accepted the cell without fault codes, completed its self-test sequence, and delivered consistent voltage throughout the discharge curve to the low-voltage cutoff point.
  • Power-on self-test — do not interrupt the startup sequence: Globus veterinary devices run a BMS verification check at every startup. If the unit is powered off during this sequence after a battery swap, the device logs a false battery fault that persists until the next full reboot. Let the boot cycle finish completely before beginning any treatment session.

Why the TecarVet 2000 alarms low battery on a freshly charged replacement cell

The TecarVet 2000 BMS stores a charge profile calibrated to the original factory cell. A new Ni-MH replacement hasn't completed a learn cycle yet, so the BMS reads the unfamiliar internal resistance signature and flags it as low capacity. This is not a fault with the cell — it is the BMS applying thresholds it hasn't yet adjusted for. Run one full charge-discharge cycle after installation. After that cycle, the BMS recalibrates and the alarm clears.

Device will not power on after the replacement cell sat in storage

Ni-MH cells self-discharge at roughly 1–2% per day at room temperature. If a replacement cell sat uninstalled for several weeks, its resting voltage may have dropped below the BMS recovery threshold — typically around 10.5V for a 12V Ni-MH pack. At that level, the BMS blocks power-on as a protection measure and will not respond to a normal start attempt. Connect the unit to mains power first and allow the charger to trickle the pack back above 11V before attempting to boot the device.

Frequently Asked Questions

The TecarVet 2000 keeps alarming low battery even though I just fully charged the new cell — is the battery faulty?

This is a BMS learn cycle issue, not a faulty cell. The device's BMS is calibrated to the internal resistance profile of the original factory cell, and a new replacement reads differently until it completes its first full cycle. Run one complete charge-discharge cycle through the unit without interrupting the boot sequence at startup. After that cycle, the BMS recalibrates and the alarm clears.

The TecarVet 2000 shuts off unexpectedly during a treatment session in the first few uses of a new battery — what's happening?

Veterinary electrotherapy devices apply a high-load pulse profile during active treatment, and new Ni-MH cells show higher internal resistance in the first 10 cycles before the cells condition properly. Under treatment load, that resistance causes a voltage sag that crosses the BMS low-voltage cutoff, tripping a protective shutdown even though the cell is not depleted. Allow the battery to complete 5–10 full charge-discharge cycles before relying on it for full clinical sessions — internal resistance drops significantly across those cycles and voltage sag stabilises.

The charge indicator on the TecarVet 2000 won't reach 100% on the first charge of the new battery — should I be concerned?

No — the device's charge IC applies a conservative current limit on cells it hasn't seen before, and Ni-MH chemistry requires a temperature-monitored termination signal that only stabilises after the first cycle. The cell is receiving a full charge even if the indicator stops short of 100%. Complete the first charge, run the device through a normal discharge, then charge again fully. On the second charge cycle the indicator will typically reach 100% and the charge IC will track the cell accurately from that point forward.
