GE 41B025AK00201 Two-Way Radio Replacement Battery 10.8V 1200mAh

Up to 20% off
New arrival
From $43.99 USD $54.99
Shipping calculated at checkout.
Fits GE two-way radios; replaces OEM part 41B025AK00201 and 41B025AK00501.
10.8V, 1200mAh Ni-MH pack delivers sustained transmit current without voltage sag during extended shifts.
Connector slides straight in with positive terminal forward; locking tab seats flush against radio housing.
We bench-tested the cell on a GE portable radio simulator; BMS accepted load draw at full voltage with no early cutoff.
On first insertion into the charger dock, remove the battery and wipe the gold contact strip with a dry cloth if the dock shows a fault LED, then reseat firmly—GE platforms need a clean contact cycle to accept the new pack before charging begins.

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.

GE Two-Way Radio — 10.8V Ni-MH Replacement Battery (41B025AK00201)

This is a 10.8V, 1200mAh Ni-MH replacement battery for GE portable two-way radios. It cross-references OEM part numbers 41B025AK00201 and 41B025AK00501. Voltage and capacity match the original pack specification exactly.

  • OEM part number coverage: Both 41B025AK00201 and 41B025AK00501 share the same voltage rail, physical form factor, and BMS handshake protocol — one replacement covers both part numbers without modification.
  • Bench tested on actual hardware: We cycled this pack through charge and full discharge on the bench. The BMS accepted the charger dock handshake on first insertion and held voltage stable through the discharge curve without tripping overcurrent protection.
  • Contact strip prep on first insertion: Ni-MH packs ship at partial charge with a thin oxidation layer on the contacts. Before seating in the dock for the first time, wipe the gold contact strip with a dry cloth. A single clean contact cycle prevents the charger from throwing a fault LED on a pack that is otherwise fine.

GE radio cuts out mid-transmission on a fresh pack

Pressing PTT draws a sudden current spike — often two to three times the standby draw — as the RF output stage ramps up. A Ni-MH pack at storage voltage, not a full resting charge, can sag enough under that spike for the BMS to trip overcurrent protection and drop the radio. This is not a faulty cell. The pack needs at least one full charge cycle before the cell chemistry stabilises under transmit load. After a full charge, resting voltage should read between 12.5V and 13.0V on a multimeter before you key up.

Bar indicator shows one fewer bar than expected after a full charge

GE portables use voltage-threshold bar indicators — each bar corresponds to a specific voltage band, not a percentage calculated by a chip. A new Ni-MH cell that has not been through a full conditioning cycle will rest slightly below its rated terminal voltage, landing in the next threshold band down. This makes a full pack look like a partial one. Run one complete charge-discharge-recharge cycle and the resting voltage will settle into the correct band, showing the expected bar count.

Frequently Asked Questions

My GE radio goes silent right when I press PTT — the pack is brand new, what's happening?

A new Ni-MH pack ships at partial charge, and the transmit current spike when you key up can pull the voltage low enough to trip the BMS overcurrent cutout. The radio goes silent because the BMS has interrupted the circuit, not because the pack is defective. Charge the pack fully before the first use in the field. After a complete charge, resting voltage should read 12.5V–13.0V on a multimeter — at that level, the BMS will hold stable through the PTT spike.

The charger dock is showing a fault LED the moment I insert the replacement pack — how do I clear it?

This almost always comes down to contact resistance, not a dead pack. Ni-MH packs arrive with a light oxidation layer on the gold contact strip that blocks the dock's BMS handshake. Remove the pack, wipe the contacts firmly with a dry cloth, and reseat it. If the fault LED persists, the pack's resting voltage may be below the dock's acceptance threshold from extended storage — leave it seated for 10 minutes, as some GE dock designs will attempt a trickle pre-charge before switching to full charge mode.

Radio is dropping to weak audio and reduced transmit range mid-shift — pack shows full bars but it's only a few hours into the day.

This is voltage sag under sustained RF output, not a capacity problem. Ni-MH cells that haven't been fully conditioned can't sustain voltage under repeated high-draw transmit cycles even when the bar indicator reads full. The bar indicator only checks voltage at rest between transmissions — it won't catch a cell that sags under load. Run two full charge-discharge cycles on the pack, then recheck; a conditioned cell holds above 10.0V under transmit load where a storage-state cell will sag below the radio's low-voltage threshold and reduce RF output.
