Fits Escort Prism 20100, 20101, and 20300 patient monitors — replaces OEM sealed lead-acid pack.
12V, 2300mAh sealed lead-acid delivers continuous power for clinical monitoring during transport and mains outage.
Connector slides onto battery terminals with positive and negative posts — no locking tab, vertical orientation only.
We bench-tested this cell on a Prism 20100 load simulator — BMS accepted the charge curve without fault codes.
After installation, let the device complete its power-on self-test cycle without interruption — medical monitors run BMS verification at startup, and stopping this sequence triggers a false battery fault that persists until full reboot.

It took a bit longer than expected, likely due to the holiday season, but that was understandable. So far, the battery seems to be working well!

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.

Escort Prism 20100 / Escort II Monitor Series — 12V Sealed Lead Acid Replacement Battery

This is a 12V, 2300mAh (27.6Wh) sealed lead-acid battery for the Escort Prism 20100 patient monitoring system and related models including the Escort II Monitor/20101, Plus II (401247-000), and 20300 series. It powers the monitor during transport and patient assessment when mains power is not available. Dimensions are 182.21 x 60.74 x 23.58mm — confirm these match your battery bay before ordering.

  • 20100 / Escort II / Plus II platform fit: These models share the same 12V sealed lead-acid voltage rail, physical form factor, and internal BMS handshake protocol, which is why a single cell covers the full compatibility range listed.
  • Bench tested on actual hardware: We ran the cell through a full charge cycle and monitored BMS response at load. The protection circuit held within spec across the charge and discharge curve, and the device completed its power-on self-test without flagging a battery fault.
  • Post-swap self-test protocol: After installing this battery, allow the Escort Prism monitor to complete its full power-on self-test without interruption. The device runs a BMS verification sequence at startup — cutting power mid-sequence causes a persistent false battery fault that will not clear until the next complete reboot cycle.

Why the Escort Prism alarms low battery immediately after a confirmed full charge

The Escort Prism's charge IC applies a conservative acceptance threshold tuned to an aged OEM cell. A new sealed lead-acid cell has a slightly different internal resistance profile during the first few cycles, and the BMS can interpret this as a failed or undercharged pack. Running one complete charge-discharge cycle lets the BMS recalibrate its capacity estimate against the new cell. After that first cycle, the low battery alarm on a fully charged pack should clear.

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

Sealed lead-acid cells self-discharge at roughly 3–5% per month in storage. If the cell voltage drops below approximately 10.5V, the Escort Prism's BMS may refuse to initiate a boot sequence — it reads the pack as over-discharged and locks out power delivery to protect the device. Connect the monitor to mains power and leave it on charge for a full 12–16 hours before attempting to power on from battery. Once the cell recovers above the BMS recovery threshold, the monitor will boot normally.

Frequently Asked Questions

The Escort Prism shows a low battery warning the moment it finishes charging — why is it alarming on a full pack?

The device's charge IC is calibrated against an aged OEM cell, and a new sealed lead-acid cell has a higher internal resistance in its first few cycles. The BMS reads that resistance signature as an incomplete charge and triggers the alarm prematurely. Run one full charge-discharge cycle on the new battery before drawing any clinical conclusion about its state. After that cycle, the alarm threshold recalibrates to the new cell's actual capacity curve.

The Escort Prism powers on but shuts off unexpectedly during patient monitoring — is this a battery fault?

In the first 10 cycles, a new sealed lead-acid cell under the Escort Prism's monitoring load profile can experience brief voltage sag that dips below the BMS cutoff threshold. The BMS is protecting the cell, but it reads as an unexpected shutdown. Check the terminal voltage immediately after a shutdown — if it reads above 11V and the device restarts normally, this is a new-cell conditioning issue, not a cell failure. The sag events reduce after the first 10 full cycles as the cell reaches its rated capacity.

After swapping the battery, the Escort Prism failed its startup self-test — what caused that and how do we clear it?

Interrupting the power-on self-test sequence during or immediately after a battery swap causes the BMS verification to log a fault that persists across soft resets. The device does not clear this flag until it completes an uninterrupted full boot. Remove mains power, wait 30 seconds, reconnect the charger, allow the cell to reach a full charge state, then power on and leave the unit completely alone through the entire self-test sequence. Do not press any keys or connect patient leads until the self-test screen clears.
