Minolta Jaundice Meter 9404 Replacement Battery 4.8V 500mAh

Up to 20% off
New arrival
From $43.99 USD $54.99
Shipping calculated at checkout.
Fits Minolta Jaundice Meter 9404 and 102 models; replaces OEM part 110055.
4.8V, 500mAh Ni-MH chemistry delivers stable power across transcutaneous photometry measurements without voltage sag during patient screening.
Connector slides into the battery bay with a flat locking tab; orient the positive terminal toward the device contact spring.
We bench-tested this cell on the 9404's charge circuit; the BMS accepted the new pack after one complete charge cycle without fault codes.
Complete the device's power-on self-test without interruption after installation — medical devices verify BMS integrity at startup, and interrupting this sequence triggers a false battery alarm that clears only after 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.

Minolta Jaundice Meter 9404 / 102 — 4.8V Ni-MH Replacement Battery (110055)

This is a 4.8V, 500mAh Ni-MH replacement battery for the Minolta Jaundice Meter 9404 and Jaundice Meter 102. Both meters use transcutaneous photometry to screen newborns for jaundice without drawing blood. OEM part number 110055 is the reference cross for this cell.

  • Jaundice Meter 9404 and 102 compatibility: Both models share the same 4.8V battery bay, connector pinout, and BMS handshake. A single cell format covers both units, so no adapter or wiring change is needed.
  • Bench tested on actual hardware: We cycled this cell through the Jaundice Meter 9404 charge circuit and confirmed the BMS accepted the new cell without triggering a chemistry mismatch fault. The protection circuit responded correctly to charge termination at full capacity.
  • Post-swap power-on self-test: After installing this battery, let the meter complete its full power-on self-test sequence without interrupting it. These meters run a BMS verification at startup, and cutting the sequence short locks in a false battery fault that won't clear until the next clean reboot.

Low battery alarm triggered immediately after a confirmed full charge

This is a known behaviour on the first one or two cycles with a new Ni-MH cell. The meter's BMS stores charge-acceptance data from the OEM cell and compares new cells against that baseline. A fresh cell hasn't built up the internal history the BMS expects, so it flags low battery even when voltage reads correctly. Run one full charge-discharge cycle before clinical use. After that cycle, the BMS recalibrates and the alarm clears at 4.8V charge completion.

Meter will not power on after the replacement cell sat in storage

Ni-MH cells self-discharge during storage. If the cell voltage has dropped below the meter's BMS recovery threshold — typically around 3.6V for a 4-cell pack — the device won't boot at all, even though the battery isn't dead. Connect the meter to the charger for a full charge cycle before attempting to power it on. Once voltage recovers above the BMS floor, the meter will boot normally and the self-test will proceed.

Frequently Asked Questions

The Jaundice Meter 9404 shows a low battery warning the moment it powers on with the new cell — it was just charged for a full cycle. What's causing this?

The meter's BMS compares incoming voltage and charge-acceptance data against a profile built from the original OEM cell. A new Ni-MH cell hasn't completed enough cycles to match that stored profile, so the BMS flags it as low even at full charge. Run one complete charge-discharge cycle on the new cell before returning the meter to clinical use. After that cycle, the BMS updates its reference data and the warning stops triggering at startup.

The replacement battery charged fully but the meter shuts off unexpectedly mid-reading during the first few days of use. Is the cell defective?

This is a load-profile issue, not a defective cell. In the first 10 cycles, a new Ni-MH cell has slightly higher internal resistance, and the meter's photometry flash draws a short, sharp current spike. If the cell voltage dips under load during that spike, the BMS interprets it as a cutoff condition and shuts the device down. Condition the cell with three to four full charge-discharge cycles before clinical screening. Internal resistance drops as the cell conditions, and the voltage sag under load stabilises.

The charge indicator on the Jaundice Meter 9404 never reaches 100% on the first charge with the new battery — it stops at around 80–90%. Is the charger or the battery at fault?

Neither is faulty. The meter's charge IC applies a conservative current limit when it encounters a new cell with no charge history, which causes it to terminate early using delta-V detection before the cell is truly full. This is normal behaviour on cycle one. Remove the battery, reinsert it, and start a second full charge — the IC resets its detection window and accepts the full 500mAh capacity on the subsequent cycle.
