Replacement battery for Sirius SXi1 XM Lynx

This replacement battery fits the Sirius SXi1 and XM Lynx satellite radios using part number SX-6900-0010. It is a new rechargeable unit built to the original specifications with a decoded chip for proper communication. The pack carries ISO9001, RoHS and CE certification and includes overcharge, over-discharge, over-voltage and short-circuit protection.

1250 mAh capacity and runtime expectations

The cell delivers 1250 mAh at 3.7 V for a total of 4.63 Wh. That capacity supports several hours of typical DAB digital listening before a recharge is needed. Runtime drops noticeably at high volume levels or in weak signal areas where the tuner works harder. Very long trips without access to a charger will exceed a single charge.

Upgrading from a worn original pack

This unit replaces an ageing original battery that no longer holds a useful charge or shows swelling. The jump is worth it when the radio shuts down prematurely or requires constant tethering to power. It is not for owners whose original cell still meets daily listening needs or for devices using a different part number.

Questions about this item

Will the 54.50 x 33.90 x 5.50 mm size fit the battery compartment of my Sirius SXi1?

The replacement cell measures 54.50 x 33.90 x 5.50 mm and weighs 20 g, matching the original Sirius SX-6900-0010 footprint so it slots into the existing compartment without modification.

How can I confirm the 3.7 V 1250 mAh pack is charging correctly after installation?

After fitting, the device should show a charging indicator and reach full capacity within a normal cycle; the built-in protection circuit prevents over-charge, over-discharge and short-circuit, so stable voltage and run-time confirm correct operation.

Does the box include a charger or tools, or must I buy them separately?

The package contains one 1250 mAh battery with shock-absorbing foam; no charger, adapter or installation tools are supplied, so reuse your existing Sirius charger or purchase a compatible 3.7 V supply separately.
