Replacement battery for Onyx Studio 7
This lithium-ion pack replaces the original Harman/Kardon GSP-1S1P-OS7A cell in the Onyx Studio 7 speaker. It delivers 3350mAh at 3.7 volts for 12.40Wh of capacity. The pack fits the speaker's internal cavity without modification. Buyers who need a different voltage or a larger capacity for another model cannot use this part.
Steady output during long playback
The cell maintains its rated voltage across extended listening sessions rather than only in short bursts. A decoded chip reports charge state to the speaker's firmware so the fuel gauge stays accurate. Protection circuits guard against overcharge, over-discharge, over-voltage and short circuits. Users who expect the battery to survive deep-cycling abuse beyond normal speaker operation will not find that guarantee here.
Slim profile with foam-protected shipping
The pack measures 77.00 x 21.00 x 21.00 millimetres and weighs 60.0 grams, matching the original footprint. Shock-absorbing foam in the retail box protects the cells during transit. The connector plugs directly into the speaker's existing header with no soldering required. Installers who lack a compatible screwdriver set or who need a battery with pre-attached mounting brackets will need additional hardware.

Questions about this item
Does the 3.7 V lithium-ion cell generate noticeable heat during extended playback on the Onyx Studio 7?
The replacement cell matches the original 3.7 V specification and includes overcharge, over-discharge and short-circuit protection, so it runs at the same temperature profile as the factory battery.
Must the speaker’s original connector and charging circuit be intact for this GSP-1S1P-OS7A pack to function?
Yes, the pack uses the same connector and decoded chip as the original 3350 mAh unit, so the speaker’s existing charging board and connector must be working.
Will the 77.00 × 21.00 × 21.00 mm dimensions fit the battery compartment of an older Onyx Studio 7 without modification?
The pack is built to the exact original dimensions of 77.00 × 21.00 × 21.00 mm, so it fits the Onyx Studio 7 compartment without any alteration.
