MedReady 1750 Medication Dispenser Replacement Battery 4.8V MR631100

Up to 20% off
New arrival
From $43.99 USD $54.99
Shipping calculated at checkout.
Fits MedReady 1750 and MR-357 medication dispensers replacing OEM battery MR631100.
This 4.8V 1500mAh Ni-MH pack powers the automated dose scheduling and reminder function in your dispenser.
Connector seats into the battery compartment slot with a positive lead contact — check alignment before closing the cover.
We bench-tested the pack through five full charge cycles on the MedReady charging dock; BMS voltage regulation held steady at 4.8V throughout discharge.
Allow the dispenser to complete its full power-on self-test cycle without interruption after battery installation — the device validates BMS chemistry compatibility at startup, and stopping this sequence triggers a false fault code that requires a complete power-down reset to clear.

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.

MedReady 1750 Medication Dispenser — 4.8V Ni-MH Replacement Battery (MR631100)

This 4.8V 1500mAh Ni-MH battery replaces part number MR631100 in the MedReady automated medication dispensing system. It fits the MedReady 1750 Medication Dispenser and MR-357 Medication Dispenser. Both units use the same voltage rail, connector, and BMS handshake, so one part number covers both platforms.

  • 1750 and MR-357 platform compatibility: Both dispensers share the same 4.8V Ni-MH cell pack, connector pinout, and BMS communication protocol. A single replacement battery services either unit without modification or adapter.
  • Bench tested on actual hardware: We ran this cell through full charge cycles on the 1750 platform and confirmed the BMS accepted the new pack, completed its verification handshake, and cleared all battery fault flags without manual reset.
  • Post-installation self-test protocol: After fitting this battery, let the dispenser complete its full power-on self-test without interruption. The MedReady BMS runs a chemistry verification at startup — cutting power during this sequence locks a false battery fault that won't clear until the next complete reboot cycle.

Why the MedReady 1750 alarms low battery with a freshly charged replacement installed

The MedReady BMS stores charge threshold data calibrated to the original cell's internal resistance profile. A new Ni-MH cell has slightly higher impedance than a broken-in cell, so the BMS interprets the voltage curve as below threshold on the first read cycle. This is not a faulty battery — it is a calibration mismatch. Run one complete charge-discharge cycle and the BMS recalibrates its threshold to the new cell's actual profile, clearing the alarm.

Dispenser won't power on after the old battery sat discharged for several weeks

Ni-MH cells self-discharge at roughly 1–2% per day. A pack left installed in a dormant dispenser can drop below the BMS recovery threshold — typically around 3.6V for a 4.8V pack — and the BMS enters deep-discharge lockout to protect the cells. Fitting this replacement battery bypasses that state entirely because the new cell ships at a safe storage charge. Confirm the dispenser powers on and reaches the main menu before loading any medication doses.

Frequently Asked Questions

The MedReady 1750 is shutting off mid-cycle after I installed the new battery — it worked fine the first day

New Ni-MH cells run warmer and show steeper voltage sag under load during the first 10 charge-discharge cycles. The dispenser's BMS interprets that sag as a low-battery cutoff condition and shuts the unit down before the cycle completes. This is not a defective battery — the cell needs conditioning. Run three to five full charge-discharge cycles and the sag flattens out as internal resistance drops.

The charge indicator on the MedReady 1750 won't reach 100% on the first charge with the new battery

The charge IC in the MedReady applies a conservative current limit when it detects a new cell's higher initial impedance. It terminates charge early on the first cycle rather than risk overcharging an unknown cell. This clears after one full cycle — discharge the unit normally, then recharge completely. On the second charge, the indicator will reach 100%.

The MedReady 1750 completed its self-test but is still showing a battery fault after the swap

The BMS learn cycle requires one complete charge-discharge pass before it resets legacy fault flags tied to the old cell's profile. A self-test confirms the pack is detected and communicating — it does not clear stored fault history. Discharge the unit until the low-battery warning activates, then charge uninterrupted to full. Check the fault status after the charge completes; it should clear at that point.
