Exact replacement for Zik 2.0 and 3.0

This Estry lithium cell matches the original 1ICP7/28/35 specification at 3.7V and 750mAh. It fits the Parrot Zik 2.0 and Zik 3.0 headphones without modification. Built-in protection guards against overcharge, over-discharge, over-voltage and short circuits. The pack is certified to ISO9001, RoHS, CE, UN38.3 and MSDS standards.

Steady output through a full listening session

The 2.78Wh cell delivers consistent voltage across the discharge curve rather than a brief peak. Protection circuitry maintains safe limits during extended playback, preventing sudden shutdown from voltage sag. At 41.0g the battery adds negligible mass to the headband. Dimensions of 39.67 x 28.0 x 7.5mm keep the original profile intact.

Replaces a worn or swollen factory pack

When the original cell no longer holds a charge or shows physical swelling, this unit restores the rated runtime. The jump is worth it if the headphones otherwise function but battery life has dropped below usable levels. Buyers who need a higher-capacity cell or a different form factor should look elsewhere.

Questions about this item

How much heat does the 3.7V 750mAh lithium pack generate during all-day use?

The 39.67 x 28.0 x 7.5 mm cell weighs 41.0 g and carries over-charge, over-discharge, over-voltage and short-circuit protection, so normal operation stays within safe thermal limits.

What must I already own to install this 1ICP7/28/35 replacement?

You need a Parrot Zik 2.0 or Zik 3.0 headset with a removable battery compartment that accepts the original 1ICP7/28/35 pack.

Will the 2.78 Wh cell work with the charging circuit in my older Zik 2.0?

Yes — the pack matches the original 3.7 V, 750 mAh specification and carries CE, RoHS, ISO 9001 and UN 38.3 certification, so the existing charger recognises it normally.
