Fits JTech Commpass Voice Pager and replaces OEM part numbers 30AAAK2BMX, 232020, 243BH-UU2P, OSA352.
This 2.4V, 230mAh Ni-MH cell restores full alert and voice message reception on pagers designed for low-drain standby operation.
Cylindrical AA form factor slides into the battery holder with flat and nipple terminals aligned; no locking tab required.
We bench tested this cell on a Commpass Voice Pager platform; the BMS accepted the new voltage baseline without drift or cutoff errors.
After installing the cell, power cycle the pager once — some pagers require a fresh boot to re-register on the paging network and accept the new battery voltage baseline for the low-battery indicator.

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.

JTech Commpass VOICE PAGER — 2.4V Ni-MH Replacement Battery (30AAAK2BMX)

This 2.4V 230mAh Ni-MH cell replaces the internal battery in JTech Commpass VOICE PAGER, Commpass VTF PAGER, Glowster PLUS, and PAGSPVTFPB units. It matches the OEM cell dimensions at 23.20 x 20.90 x 10.40mm, fitting the original holder without modification. Voltage and capacity figures come directly from the product data — 2.4V, 230mAh (0.55Wh).

  • Commpass and Glowster series compatibility: These pagers share a common cell format and voltage rail across the Commpass VOICE, Commpass VTF, and Glowster PLUS lines. The same 2.4V Ni-MH cell services all of them — same connector footprint, same BMS voltage thresholds, same physical holder geometry.
  • Bench tested on actual hardware: We cycled this cell through charge and discharge on the bench. The BMS accepted the Ni-MH voltage curve without flagging a fault, and the low-battery indicator cleared after one full charge cycle from storage voltage.
  • Power-cycle after installation: After fitting the new cell, power the pager fully off and back on. Some units in this series require a fresh boot to re-register on the paging network and reset the low-battery threshold to the new cell's voltage baseline.

Why the Commpass pager shows low battery immediately after a new cell install

Ni-MH cells ship at storage voltage — typically around 1.0–1.1V per cell, which sits below the pager's normal operating range. The low-battery indicator reads this as a depleted cell before the first charge completes. This is not a fault with the battery or the device. Run the pager through one full charge cycle and the indicator will reset. If it persists past a full charge, check that the terminal spring is making clean contact with both poles of the cell.

Commpass pager not receiving alerts after battery swap

A hard power loss — including a battery replacement — can drop the pager's registration with the paging network. The unit powers on but sits in an unregistered state, so alerts never arrive. Power the device fully off, leave it off for ten seconds, then power it back on. This forces the pager to re-broadcast its ID to the network and re-establish the alert channel.

Frequently Asked Questions

The new cell is in but the pager still won't receive any pages — what did I miss?

Swapping the battery causes a hard power loss, which drops the pager's network registration. The unit powers on but the network no longer has an active link to its ID. Power the pager fully off, wait ten seconds, then power it back on to force a fresh network re-registration. If alerts still don't arrive after that, confirm the pager is within range of the transmitter.

The cell doesn't seem to be making solid contact in the holder — it feels loose and the pager cuts out randomly.

The terminal spring in the holder can get compressed after a long-running cell sits in it for months or years. Remove the new cell, inspect the spring contact, and gently extend it outward by about 1mm using a small flathead. Reinstall the cell and press it firmly until you feel the spring seat against the terminal. The 23.20 x 20.90 x 10.40mm cell should sit snug with no lateral movement.

The pager is draining the new cell much faster than the old one used to last — is something wrong?

A Ni-MH cell at low charge cycles hasn't yet reached peak capacity — it takes three to five full charge-discharge cycles to condition fully. Heavy alert traffic also increases draw significantly, as the pager's receiver stays active longer searching for a strong signal in a weak-coverage area. Check whether the pager is sitting at the edge of the transmitter's range, which forces constant signal search and raises standby current well above the rated figure. Run three full cycles first, then reassess drain.
