Battery Care Tips
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
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 Volumat Agilia Infusion Pump — 7.4V Li-ion Replacement Battery (179033-R0)
This 7.4V, 2600mAh Li-ion battery replaces the original pack in the Fresenius Volumat Agilia and Volumat Agilia D infusion pumps. It matches OEM part numbers 179033-R0, BATT/110320, MB1790, and 88888749. The same cell fits the broader Fresenius Volumat pump platform where those part numbers cross-reference.
- Volumat Agilia platform fit: The Agilia and Agilia D share the same 7.4V power rail, connector pinout, and BMS communication protocol. A single battery SKU covers both variants because the charge IC expects identical cell chemistry and voltage thresholds across the range.
- Bench tested on actual hardware: We cycled this cell on the Volumat Agilia platform and logged BMS handshake, charge acceptance, and cutoff behaviour. The protection circuit triggered correctly at low-voltage cutoff and accepted a full charge to 8.4V without fault flags.
- Post-installation self-test cycle: After fitting this battery, allow the pump to complete its full power-on self-test without interruption. The Volumat Agilia 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 Volumat Agilia alarms low battery immediately after a confirmed full charge
The pump's BMS stores capacity thresholds calibrated to the original cell's charge history. A new replacement cell has no cycle data, so the BMS cannot yet verify it meets the internal pass threshold. This triggers a low-battery alarm even when the cell sits at full voltage. One complete charge-discharge cycle lets the BMS record actual capacity data and clears the alarm on subsequent boots.
Volumat Agilia fails to complete boot sequence after battery sat in storage
Li-ion cells self-discharge in storage. If a replacement battery has been on a shelf for several months, its resting voltage may fall below the pump's BMS recovery threshold — typically around 6.0V for a 7.4V nominal pack. Below that threshold, the BMS locks out the discharge path and the pump will not boot. Connect the battery to a compatible charger first and allow it to recover to at least 7.0V before installing it in the pump.

Frequently Asked Questions
The Volumat Agilia shows a low battery alarm straight after I fitted the new battery and charged it fully — why?
The pump's BMS stores a capacity baseline from the previous cell's cycle history. A new cell has no logged cycles, so the BMS cannot confirm it meets the internal pass threshold and raises the alarm as a precaution. Run one full charge-discharge cycle on the pump before clinical use. After that cycle, the BMS records real capacity data from this cell and the alarm clears on the next boot.
The Volumat Agilia won't power on at all after the replacement battery was in storage for a few months — what's happening?
Li-ion cells self-discharge over time, and the Volumat Agilia's BMS locks the discharge path when cell voltage drops below the recovery threshold — roughly 6.0V on a 7.4V nominal pack. The pump cannot draw enough voltage to initiate boot. Connect the battery to a compatible charger and let it recover to at least 7.0V before installing it; the BMS will re-enable the discharge path and the pump will boot normally.
The charge indicator on the Volumat Agilia stops short of 100% on the first charge of the new battery — is the cell faulty?
The charge IC applies a conservative current limit on cells with no cycle history — it cannot yet verify the cell's internal resistance profile, so it terminates early as a safety measure. This is not a fault. Run the pump through one complete charge-discharge cycle and the charge IC recalibrates its termination point. The indicator will reach 100% on the second charge.
