Replacement battery for legacy Sony Clie models

This Centenex Electronics BASONYNR70 lithium-polymer cell delivers 1200mAh at 3.7V and fits a wide range of Sony Clie handhelds including the PEG-NR70, PEG-NX70, PEG-NX80 and PEG-TH55 series. It replaces original part numbers such as LIS1241 and UP503759-NR70, restoring power to devices that no longer hold a charge with their factory packs.

Steady output during extended handheld use

The 4.44 Whr Li-Polymer chemistry maintains a stable voltage curve across long work sessions, avoiding the sharp drop-off seen in aged nickel-based packs. Users can rely on consistent runtime for calendar sync, document editing or email retrieval without the device shutting down prematurely under moderate load.

Slim profile matches the original battery bay

At 58.73 x 36.51 x 4.76 mm the silver cell slides into the compartment without shims or force, and the original battery door closes flush. The connector aligns with the Clie's internal header so no soldering or adapter wiring is required, making the swap a straightforward field replacement.
