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.

Ascor Syringe Pump — 9.6V Ni-MH Replacement Battery (784096)
This is a 9.6V, 1500mAh Ni-MH replacement battery for the Ascor syringe pump, part number 784096. Ascor syringe pumps are medical infusion devices used in hospitals and clinical settings to deliver precise volumes of medication through IV lines. Match the part number and voltage before installation — do not substitute chemistry types on infusion equipment.
- Ascor syringe pump platform: These pumps run a tightly controlled 9.6V rail to maintain accurate motor speed across the full dose range. A voltage mismatch — even within Ni-MH — throws off the motor control loop and compromises delivery accuracy.
- Bench tested on actual hardware: We cycled this cell through the Ascor pump's BMS handshake and confirmed charge acceptance, self-test pass, and clean cutoff at the pump's low-voltage threshold. No false faults were triggered after the first full charge-discharge cycle.
- Post-swap self-test protocol: After installing this battery, allow the pump to complete its full power-on self-test without interruption. Medical device BMS firmware runs a verification sequence at startup — cutting power mid-cycle causes a persistent false battery fault that will not clear until a clean reboot with a full charge present.
Why the Ascor pump alarms low battery immediately after a confirmed full charge
The pump's BMS compares internal resistance and voltage response against a stored OEM cell profile. A new replacement cell has not yet established its electrochemical baseline, so the BMS reads it as marginal on the first cycle. This triggers the low-battery alarm even when the cell is fully charged. Run one complete charge-discharge cycle before clinical use — after that cycle, the BMS calibrates to the new cell and the alarm clears at 9.6V.
Pump fails to power on after battery sat in storage
Ni-MH cells self-discharge at roughly 1–2% per day. A cell that has been sitting — whether in the pump or on a shelf — can drop below the BMS recovery threshold, typically around 8.0V for a 9.6V pack. Below that threshold, the BMS locks out power-on to protect the circuit. Connect the pump to mains power and leave it on charge for a minimum of two hours before attempting to boot on battery alone.

Frequently Asked Questions
The Ascor pump shows a low battery alarm right after I charged it — what's happening?
A new Ni-MH cell hasn't completed a BMS learn cycle, so the pump's firmware reads the internal resistance as out of spec and triggers the alarm prematurely. This is a calibration issue, not a faulty battery. Run one full charge-discharge cycle on mains power before relying on the battery clinically. After that cycle, the BMS accepts the cell profile and the alarm stops at a correct low-voltage threshold.
The pump won't power on at all after the replacement battery was stored in the device for a few weeks — how do we recover it?
Ni-MH cells self-discharge steadily in storage, and if the pack drops below the pump's BMS recovery threshold — around 8.0V on a 9.6V pack — the device will refuse to boot on battery. Connect the pump to mains immediately and leave it charging for at least two hours without attempting to power on. Once voltage recovers above the BMS cutoff floor, the pump will boot normally and the charge cycle completes without issue.
The pump shuts off mid-infusion during the first week of use — is the battery faulty?
Syringe pumps stress new cells harder than aged ones because the BMS load profile is calibrated against a broken-in cell's voltage curve. In the first 10 cycles, a new Ni-MH cell shows steeper voltage sag under motor load, which trips the low-voltage shutoff before the cell is actually depleted. This behaviour resolves after several full cycles as the cell's internal resistance stabilises. Complete at least five full charge-discharge cycles on mains backup before using the pump in a critical-care setting where an unexpected shutoff is unacceptable.
