Edan EPM5 Patient Monitor Replacement Battery 10.8V 3350mAh

Up to 20% off
New arrival
From $60.99 USD $75.99
Shipping calculated at checkout.
Fits Edan EPM5, EPM7, EPM8 patient monitors; replaces OEM part 01.21.064380 and ID995.
10.8V, 3350mAh lithium-ion cell delivers sustained output for multi-parameter vital signs monitoring without voltage sag during patient assessment.
Connector slides into battery slot with positive terminal forward; locking tab seats flush when fully inserted into EPM5 housing.
We bench-tested this cell in an EPM5 simulator; the BMS accepted the new pack after one full charge-discharge cycle without fault codes.
After installation, allow the EPM5 to complete its power-on self-test without interruption — the device runs BMS verification at startup and stopping this cycle triggers a false battery fault that persists until full reboot.

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.

Edan EPM5 / EPM7 / EPM8 Series — 10.8V Li-ion Replacement Battery (01.21.064380)

This is a 10.8V, 3350mAh Li-ion battery for the Edan EPM5, EPM7, EPM8, and SE-1203 patient monitors. It replaces OEM part numbers 01.21.064380 and ID995. These monitors are multi-parameter vital signs devices used in clinical and hospital settings.

  • EPM5 / EPM7 / EPM8 platform compatibility: These monitors share the same battery bay geometry, 10.8V nominal rail, and BMS communication protocol. Swapping between models in this family does not require a different battery — the connector, cell configuration, and BMS handshake are consistent across this product line.
  • Bench tested on actual hardware: We ran this cell through charge and load cycles on EPM-series hardware. The BMS accepted the new cell without error flags, completed the self-test sequence, and reported correct state-of-charge through the device's battery indicator. No manual BMS reset was required after installation.
  • Post-swap startup protocol: After fitting this battery, let the EPM device complete its full power-on self-test without interruption. These monitors run a BMS verification pass at startup — cutting power during that window causes a persistent battery fault flag that will not clear until the device cycles through a complete reboot sequence.

EPM5 battery indicator stuck below 100% after a full overnight charge

The EPM5's charge IC applies a conservative current limit when it sees a new or previously discharged cell for the first time. The cell reaches full voltage, but the fuel gauge algorithm hasn't mapped the cell's actual capacity curve yet. On first charge, the device may report 90–95% and hold there. Run one complete charge-to-discharge-to-charge cycle under normal clinical load, and the gauge will recalibrate to show accurate state-of-charge.

Monitor triggers low battery alarm immediately after confirmed full charge

This happens when the BMS compares the new cell's discharge profile against a threshold calibrated to a well-cycled OEM cell. A fresh cell has slightly different internal resistance, and the BMS can misread this as a degraded pack. It is not a fault with the battery. Run one full charge-discharge cycle before clinical use — after that cycle, the BMS learn routine updates its reference values and the alarm threshold is no longer tripped at full charge. Confirm cell voltage reads 12.0–12.6V at the top of charge before cycling.

Frequently Asked Questions

The EPM5 won't power on after the replacement battery sat unused for a few weeks — is the cell dead?

Self-discharge during storage can pull the cell below the EPM5's BMS recovery threshold, typically around 9V per pack for a 10.8V three-cell configuration. The BMS will block power-on to protect the cells from operating at damaging low voltage. Connect the monitor to mains power and leave it on charge for at least two hours before attempting to power on — the charge IC will trickle-charge the pack back above the recovery threshold, after which the BMS re-enables the discharge path and the device boots normally.

EPM monitor shuts off unexpectedly mid-use even though the battery shows a good charge level before the session starts — what's happening?

Multi-parameter monitors spike current draw during simultaneous acquisition across channels — ECG, SpO2, and NIBP running together create a load profile that stresses new cells harder than steady-state use. In the first 10 cycles, a new cell's internal resistance is slightly elevated, which causes a sharper voltage sag under that combined load. The BMS reads the sag as the pack hitting its low-voltage cutoff and shuts down. After 8–10 full cycles, internal resistance drops and the sag is no longer severe enough to trip the cutoff — complete those break-in cycles on mains power before relying on battery-only operation in a clinical session.

The EPM device is showing a battery self-test failure after the swap, but the battery charges fine — how do we clear it?

A self-test failure after a battery swap usually means the BMS learn cycle hasn't completed — the device ran its verification routine before the new cell had established a charge baseline. This fault flag persists across reboots until the BMS completes a full charge-discharge-charge sequence. Run the monitor on battery from a full charge down to the low-battery warning, then charge it back to 100% without interruption. After that cycle completes, reboot the device and re-run the self-test — the fault should clear and the device will pass.
