Exact Replacement Battery

The Estry S60526 is a 3.6V 1200mAh nickel-metal hydride pack built to the same dimensions and electrical ratings as the original BT-33 cell. It suits owners of devices that specify this exact model number and need a direct swap without modification.

Standard Ni-MH Limits

Nickel-metal hydride chemistry delivers 4.32Wh from a 3.6V platform and self-discharges faster than lithium types, so the pack should be cycled regularly and not left flat for long periods. Overcharge, over-discharge, over-voltage and short-circuit protection circuits are integrated to extend service life.

Verify Model and Part Number

Before ordering, confirm that your equipment lists the S60526 model or BT-33 part number on the old battery label or in the service manual. The physical envelope measures 50.43 x 42.54 x 14.4mm and weighs 90.3g; ensure the compartment and connector match these dimensions exactly.
