Direct replacement for Clie PEG-UX40 and PEG-UX50

This 3.7V 850mAh Li-Polymer battery matches the original 1-756-381-11 and UP553 part numbers. It fits the Sony Clie PEG-UX40 and PEG-UX50 handheld PCs without modification. The pack measures 50.14 x 29.73 x 4.63 mm and ships in black.

Suitable for owners restoring a working UX-series

Users who need a fresh power source for daily PDA tasks will find the capacity identical to the factory cell. Buyers who want more storage or a higher-capacity pack should look elsewhere, as this unit replicates the original 0.85 Ah rating only.

Steady output through a full workday

The lithium-polymer chemistry delivers consistent voltage during extended note-taking, scheduling or sync sessions. Heat build-up remains low under continuous discharge, so the handheld stays comfortable in hand until the charge is depleted.
