SKU CH-70B2-PMNS2

Rechargeable 3.7 V lithium-ion cell powers the HUB UltraLITE headset for six hours and swaps in seconds

  • Lightweight matchbook-size battery fits inside headset

  • Recharges in about 3 hours for quick turnaround
  • Delivers up to 6 hours of talk time
  • Swappable in seconds for continuous operation

Direct replacement battery

This 3.7 V lithium-ion cell is made for the Eartec HUB UltraLITE headset. It fits inside the all-in-one headset housing and weighs about the same as a book of matches. The pack charges in roughly three hours and delivers up to six hours of talk time. No memory effect means it can be topped up after any shift.

Upgrade from worn cells

Replace the original battery when run-time drops below a full work day or the pack no longer holds a charge. The swap takes seconds and requires no tools because the cell sits in the headset plastics. Lithium-ion chemistry removes the need to drain the pack before each recharge. Users who run multiple shifts can keep a spare on hand for instant change-over.

Check headset model first

Verify the headset is the HUB UltraLITE; other Eartec models use different packs. Confirm the existing cell is a 3.7 V lithium-ion unit of similar physical size. Ensure the charging cradle or cable supplied with the headset is still functional. No additional hardware or firmware update is required for the replacement.
