Replacement Battery for Sony SRS-XB501

This lithium-polymer pack replaces the original ID659B cell inside the Sony SRS-XB501 and SRS-XB501G portable speakers. It delivers 5200mAh at 7.4V, matching the factory energy rating of 38.48Wh. The pack measures 67.94 x 37.58 x 37.02mm and weighs 190g.

Fully decoded chip and protection circuit

A new fully decoded chip communicates with the speaker exactly like the original battery, so the fuel gauge and charging logic work without modification. Built-in protection guards against over-charge, over-discharge, over-voltage and short circuits. The retail box includes shock-absorbing foam for safe transit.

Single-cell 7.4V lithium-polymer limits

The pack uses a two-cell series lithium-polymer design fixed at 7.4V nominal, so it cannot be used in devices that require a different voltage or cell count. Capacity will reach its rated 5200mAh only after two or three full charge-discharge cycles. A low-quality charger can reduce cycle life, so the original or an equivalent power supply is recommended.

Questions about this item

How many charge cycles before the 5200mAh lithium-polymer pack needs replacement?

The battery reaches its best performance after 2 or 3 full charge and discharge cycles; typical lithium-polymer packs last several hundred cycles before noticeable capacity loss.

What is the first limit reached during continuous playback at high volume?

The 38.48Wh capacity and 7.4V output set the runtime ceiling; sustained high-drain use will deplete the charge before thermal limits appear.

Does the 190g pack get hot or make noise during all-day operation?

Lithium-polymer chemistry runs silently and produces minimal heat under normal speaker loads; the built-in protection circuit prevents over-temperature conditions.
