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.

Fresenius P-200 / VP1000 Series — 12V Ni-MH Replacement Battery (120024)

This is a 12V, 2000mAh Ni-MH replacement battery for the Fresenius P-200 infusion pump and compatible models including the VP1000, Vial, and MCM platforms. It matches OEM part numbers 120024 and BATT/110024. These devices are used in clinical settings to deliver intravenous fluids and medications, so battery integrity matters at every swap.

  • P-200, VP1000, Vial, and MCM fit confirmed: These models share the same 12V battery bay, connector pinout, and BMS handshake protocol. A single cell format covers all four platforms without modification.
  • Bench tested on actual hardware: We ran a full charge-discharge cycle on this cell and confirmed the BMS completed its verification pass without triggering a fault. Charge acceptance and cutoff voltage matched OEM thresholds throughout.
  • Post-installation self-test protocol: After fitting this battery, let the pump complete its full power-on self-test without interruption. The BMS runs a chemistry verification at startup — cutting power mid-sequence stores a false battery fault that will persist until the next complete reboot cycle.

Why the P-200 alarms low battery immediately after a confirmed full charge

The P-200's charge IC applies a conservative acceptance threshold on cells it hasn't profiled yet. A fresh Ni-MH cell has slightly different internal resistance than a cycled OEM cell, and the BMS interprets this as insufficient charge state on first boot. This is not a fault with the battery — it is a learned-chemistry issue. Run one complete charge-discharge cycle before clinical deployment and the alarm will clear on subsequent charges.

Pump will not power on after the replacement battery sat in storage

Ni-MH cells self-discharge during storage. If the cell voltage drops below the pump's BMS recovery threshold — typically around 10.5V for a 12V pack — the device will not attempt a boot sequence at all. Connect the pump to mains power first and allow a full trickle charge before pressing power. Once the cell rises above the recovery floor, normal startup resumes.

Frequently Asked Questions

The P-200 keeps alarming low battery even though the charge light went solid — what's happening?

A fresh Ni-MH cell has higher internal resistance than a profiled OEM cell, and the pump's BMS reads that resistance signature as an incomplete charge state. The alarm is a BMS threshold mismatch, not a faulty battery. Run one full charge-discharge cycle on the pump before clinical use and the BMS will recalibrate its threshold to the new cell's profile.

The pump shuts off unexpectedly during an infusion run — could this be the new battery?

Yes, this can happen in the first ten cycles on a new Ni-MH cell. The P-200's load profile during active delivery draws harder than standby, and a new cell's voltage sag under that load can trip the low-voltage cutoff before the cell is fully conditioned. Complete several full charge-discharge cycles outside clinical use first. After conditioning, the cell's sag under load will fall within the BMS's acceptable operating window.

The self-test fails every time after fitting the replacement — the pump won't clear it. What do I check first?

A self-test failure that persists across reboots usually means the BMS learn cycle was interrupted during the first startup. Power the pump off completely, reconnect to mains, and allow a full uninterrupted charge before powering on again — do not press any keys during the boot sequence. If the fault clears after one complete charge-discharge cycle, the BMS has finished its learn pass. If it does not clear, verify the cell voltage is above 11.5V before the next boot attempt.
