Questions about this item

Does the battery ship with any cables, connectors or tools, or must I buy them separately?

The replacement cell is supplied as a standalone 150 mAh 3.7 V unit measuring 32.20 x 25.00 x 9.40 mm and weighing 7.0 g; no cables, connectors or tools are included in the package.

My headset is a Set 840 — is this the correct capacity for that model?

Yes, the 150 mAh 0.56 Wh 3.7 V cell matches the original specification for the Set 840 and all other listed Sennheiser models including IS 410, RI 410, RR 4200, RS 4200 and Set 830/900.

What does the 150 mAh rating actually deliver in daily use with a Set 830 TV headset?

The 0.56 Wh capacity restores the original runtime for the Set 830 TV; a fresh cell typically powers several hours of listening before needing a recharge, and reaches full performance after two to three charge cycles.
