Direct replacement for Xperia devices

This Cameron & Co DS-CS-ERX1SL is a new 3.7V 1500mAh Li-ion cell phone battery. It fits a long list of Sony and Sony Ericsson models including the Xperia Play, Xperia neo L, Xperia X10 series and the PlayStation Phone. The 5.6Wh capacity restores original runtime for daily calls and messaging. Builders repairing legacy handsets will find the BST-41 and SO04 cross-reference useful.

Single-cell pack with no extras

The package contains one black battery cell rated at 1.5Ah. No charger, tools, adhesive strips or software are included, so the buyer must reuse the original phone’s charging circuit and housing. The 100% OEM-compatible claim means the cell matches the factory voltage and connector layout, leaving installation straightforward for experienced users.

Slim 4.85mm profile fits tight bays

Measuring 64.38 x 44.15 x 4.85mm, the pack slides into the narrow battery compartments of the listed Xperia and Ericsson handsets without forcing the cover. The standard three-terminal interface aligns with the phone’s existing contacts, preserving water-resistance seals where the original design included them. Buyers needing higher capacity or a different form factor should look elsewhere.

Questions about this item

When will the 1500 mAh Li-ion cell need replacing?

The 1500 mAh lithium-ion cell gradually loses capacity over charge cycles; plan to swap it once run-time drops below your daily needs.

What limits the BST-41 compatible pack during continuous use?

The 5.6 Wh capacity sets the runtime ceiling; sustained loads drain the 3.7 V cell until voltage falls below the phone's cutoff.

How warm does the 64.38 mm battery get under all-day load?

Normal operation keeps the 4.85 mm thick pack near body temperature; heavy continuous draw may raise it slightly but stays within safe limits.
