Replacement Battery for BeoPlay H7 H8 H9 H9i

This Centenex Electronics lithium-ion cell replaces the original Bang & Olufsen 1973822 PLB-103 pack. It delivers 3.7V and 650mAh capacity in a black housing measuring 39.80 x 35.50 x 6.00 mm. The unit is brand new and built to 100% OEM compatibility for wireless headsets.

Upgrading from a Depleted Original Cell

When the factory battery no longer holds a useful charge, this 2.41 Wh replacement restores full runtime without soldering or adapter cables. The jump is worth it if your headset powers off early or shows reduced playback time. No firmware update or configuration is required after installation.

Suits Owners of Listed BeoPlay Models

This pack fits BeoPlay H7, H8, H9 and H9i headsets that use the 1973822 or PLB-103 part numbers. Buyers whose headset uses a different battery code or form factor should look elsewhere. Technicians needing a higher-capacity cell or a different voltage will not find those options here.

Questions about this item

Will the 39.80 x 35.50 x 6.00 mm dimensions fit my BeoPlay H7 battery compartment?

Yes, the 39.80 x 35.50 x 6.00 mm size matches the original 1973822 PLB-103 cell used in BeoPlay H7, H8, H9 and H9i headsets.

What is the correct polarity orientation when inserting this 3.7V 650mAh Li-ion pack?

Align the gold contacts on the battery with the matching pads inside the earcup; the keyed connector only seats one way, so do not force it.

When should I expect to replace this 2.41 Wh battery based on charge cycles?

Li-ion packs of this chemistry typically deliver several hundred full cycles before capacity drops noticeably; replace when runtime falls below your needs.
