Questions about this item

Does the 3.6V 700mAh Ni-MH pack run hot or draw extra current during continuous daily use?

The cell is built to the original 3.6V 700mAh 2.52Wh specification and includes overcharge, over-discharge, over-voltage and short-circuit protection, so it stays within normal temperature limits during all-day operation.

Must I already own a Sylvania handset that takes the ST88207 or ST88201 pack for this replacement to work?

Yes — the battery is a direct replacement for Sylvania models ST88207 and ST88201; it will only function in devices designed for those exact part numbers.

Will the 50.79 x 42.4 x 14.23mm dimensions fit the battery compartment of my older Sylvania ST88201 phone without modification?

The pack matches the original ST88201/ST88207 footprint of 50.79 x 42.4 x 14.23mm and weighs 114.3g, so it drops straight into the existing compartment with no alteration needed.
