Jabra Pro 900 / 920 / 923 / 930 / 935 Battery Replacement – AHB5-2229PS

Jabra Pro headset losing charge during calls? Check the charging setup and identify the original battery before considering an internal replacement.

Reduced runtime can be consistent with battery aging, but charging contacts, the base, power supply, and internal electronics may also need attention. A battery replacement is not a guaranteed solution to every charging fault or dropped call.

Replacement Option: 3.7V 300mAh Li-Polymer Replacement Battery for Jabra Pro 900, 920, 923, 930 & 935 Wireless Headsets (Reference: AHB5-2229PS). Compare the original pack and its connections before ordering.

1. Technical Specifications & Compatibility

The STARNOVO replacement listing specifies:

  • Battery reference: AHB5-2229PS
  • Nominal voltage: 3.7V
  • Rated capacity: 300mAh Li-ion polymer
  • Listed dimensions: 6.0 × 20.5 × 32.0 mm
  • Listed applications: Jabra Pro 900, Pro 920, Pro 923, Pro 930 and Pro 935 headsets
  • Pictured connection: Separate red and black wire leads without a connector plug

These are replacement-product specifications, not verified specifications for every original pack or headset revision. This is a third-party STARNOVO product, not an original Jabra battery. Do not assume all listed models have identical housings or installation procedures. Compare the original label, voltage, dimensions, available space, wiring and connection method.

2. Check Charging Before Replacing the Battery

Check that the correct power supply and base are connected and the headset is seated as instructed for the exact model. Inspect accessible charging contacts for visible damage or contamination. Follow the model's manual or contact Jabra support for charging and reset instructions.

If the battery is swollen, leaking, unusually hot or physically damaged, stop using and charging the headset and seek qualified repair assistance. Do not squeeze, puncture or flatten the battery.

3. Jabra Pro 900-Series Battery Replacement: Repair Planning

This is an internal electronics repair, not a universal teardown or a timed plug-and-play procedure. The pictured STARNOVO replacement has wire leads, so instructions that simply tell you to unplug and reconnect a battery connector do not describe this replacement as supplied.

  • Identify the exact model and revision: Use repair information matching the headset rather than assuming a common opening method.
  • Disconnect external power: Power off and remove the headset from its charging base before internal servicing.
  • Document original connections: A technician should record battery orientation, wire-to-board positions, polarity and cable routing before disturbing them.
  • Verify the replacement: Compare the original assembly with the listed dimensions and wiring. Do not infer polarity from wire colours alone or alter wiring to force a match.
  • Use qualified assistance: Have any required soldering performed by an electronics repair technician. Do not solder directly to a bare cell or bypass protection circuitry.
  • Avoid physical damage: Do not pry against, bend or compress the pouch. Stop if removal would damage the cell or attached wiring.
  • Reassemble without pressure: Keep wires clear of seams and fasteners. Do not force the housing closed over the battery.

If the connection method or fit is uncertain, stop and ask for help before installation. No installation time is promised.

4. What to Expect After Replacement

If battery aging caused the fault, a suitable replacement may improve usable runtime. It will not repair a faulty charging base, damaged contacts, radio problems or other electronic faults. The 300mAh rating alone does not establish a guaranteed number of talk-time hours.

After complete reassembly, follow the charging instructions for the exact headset. Test charging, calls, microphone and audio during normal use. Stop charging if unusual heat, swelling, odour or unstable operation occurs. This guide does not prescribe repeated full discharge cycles or an unverified docking-reset sequence.

5. Common Mistakes to Avoid

  • Diagnosing by one symptom: Short runtime and dropped calls do not prove the battery is the sole cause.
  • Buying by capacity alone: Voltage, dimensions, wiring and physical clearance also matter.
  • Assuming connector installation: Check the actual replacement photo and original assembly.
  • Pulling wires or forcing the case: Both can damage the battery or surrounding electronics.
  • Expecting guaranteed runtime: Actual results depend on the headset's condition and use.

6. Choosing Your STARNOVO Replacement Battery

The listed replacement has reference AHB5-2229PS, a 3.7V nominal voltage, 300mAh rated capacity and dimensions of 6.0 × 20.5 × 32.0 mm. Review the current product listing and compare it with the original battery before ordering.

For comparison help, email sales@starnovo.com with the exact headset model and clear photos of the original battery label and connections. Repair shops can also enquire about volume supply.
