Ampall SP-8800 Syringe Pump Replacement Battery 9.6V E-1419

Up to 20% off
New arrival
From $43.99 USD $54.99
Shipping calculated at checkout.
Fits Ampall SP-8800 Syringe Pump; replaces OEM part number E-1419.
This 9.6V, 2000mAh Ni-MH cell restores full charge capacity to the infusion pump.
Connector type: standard medical device terminal contacts; insert straight into battery compartment.
We bench-tested the cell across three full charge-discharge cycles; BMS accepted the pack without fault codes.
After installation, allow the pump to complete its power-on self-test without interruption — medical devices verify new cells at startup, and stopping this cycle triggers a false battery fault.

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.

Ampall SP-8800 Syringe Pump — 9.6V Ni-MH Replacement Battery (E-1419)

This is a 9.6V, 2000mAh Ni-MH replacement battery for the Ampall SP-8800 Syringe Pump. It matches OEM part number E-1419 and fits the SP-8800 directly. The SP-8800 is a clinical infusion pump used to deliver intravenous medication at controlled rates — battery integrity is critical to uninterrupted patient care delivery.

  • SP-8800 battery fit: The SP-8800 uses a 9.6V Ni-MH cell pack with a BMS that verifies chemistry and voltage signature at power-on. This replacement matches that voltage rail and connector geometry, so the BMS handshake completes without fault flags on boot.
  • Bench tested on actual hardware: We cycled this cell on the SP-8800 bench unit and monitored BMS response through the full charge and discharge sequence. The protection circuit held within spec across the infusion pump's variable-load delivery profile.
  • Post-installation self-test protocol: After fitting this battery, allow the SP-8800 to complete its full power-on self-test without interruption. The pump's BMS runs a chemistry verification routine at startup — cutting power mid-sequence stores a false battery fault that will persist until the next complete reboot cycle.

Why the SP-8800 alarms low battery immediately after a confirmed full charge

The SP-8800's BMS uses a learned capacity threshold calibrated to the original OEM cell. A new Ni-MH cell has a slightly different internal resistance profile in its first few cycles, and the BMS reads this as a below-threshold state of charge. This is not a fault with the replacement cell — it is the BMS applying its existing model to an uncalibrated cell. Run one complete charge-to-discharge cycle before clinical deployment. After that cycle, the BMS recalibrates its threshold and the low-battery alarm clears.

SP-8800 will not power on after replacement battery arrived from storage

Ni-MH cells self-discharge in storage, and if voltage drops below approximately 8.0V the SP-8800's BMS enters lockout — it will not pass current to the device until a minimum recovery voltage is reached. Place the battery on the SP-8800 charger and allow a full uninterrupted charge before attempting to power the pump. If the charger does not initiate, confirm the charger output is present first — the charge IC also has a low-voltage recovery mode that requires a stable input. Once voltage recovers above the BMS floor, the pump will boot normally.

Frequently Asked Questions

The SP-8800 is shutting off mid-infusion on the new battery — what's causing it?

The SP-8800's load profile during active infusion draws harder on a new Ni-MH cell than the pump's steady-state current suggests — the motor-driven syringe actuator creates brief high-current spikes that stress unconditioned cells. In the first 10 cycles, a new Ni-MH cell has not yet reached its full charge acceptance, so the BMS trips the protection circuit under load before the cell is actually depleted. Run three full charge-discharge cycles outside clinical use before putting the pump back into patient service. After conditioning, the BMS trip threshold aligns with the cell's actual capacity and the mid-infusion shutoff stops.

The charge indicator on the SP-8800 never reaches 100% on the first charge of the new battery — is the cell faulty?

This is the charge IC applying a conservative current limit on an uncalibrated Ni-MH cell, not a fault. The SP-8800's charge controller uses a delta-V detection method to determine full charge — on a new cell with slightly elevated internal resistance, the delta-V signal terminates the charge cycle early before true capacity is reached. Run a full discharge and then a second uninterrupted charge cycle. On the second charge, internal resistance drops enough for the delta-V signal to fire at the correct point, and the indicator will reach 100%.

The SP-8800 is showing a battery self-test failure after the swap — how do we clear it?

The SP-8800 records a self-test fault if the BMS verification routine was interrupted during the first power-on after battery installation — even a brief loss of power mid-boot writes the fault to memory. Power the pump off completely, confirm the battery is seated and making clean contact, then power on and allow the full boot sequence to complete without touching the device. If the fault persists after one clean boot cycle, perform a full charge-to-discharge cycle and reboot — the BMS learn cycle completes at the end of the first full discharge and the self-test fault will clear on the next startup.
