Replacement battery for Creative Zen Micro Photo

This Estry lithium battery replaces the original power cell in Creative Zen Micro Photo 8G, 4G and standard models. It matches the factory voltage of 3.7V and delivers a rated capacity of 850mAh for direct compatibility. Buyers who need a higher-capacity pack or a different form factor will not be served by this single-cell unit.

Thermals noise and power draw

The cell uses standard lithium chemistry with built-in protection against overcharge, over-discharge, over-voltage and short circuits. No active cooling or fan is involved, so operation is silent and heat output stays low during normal charging and playback. The pack weighs 41.0g and measures 54.58 x 33.69 x 4.3mm, fitting the original battery compartment without modification.

Deciding specification 850mAh capacity

The 850mAh rating at 3.7V determines whether this cell restores the player's original run-time between charges. A lower figure would shorten listening sessions while a higher one would require a different physical size. Certifications include ISO9001, RoHS, CE, UN38.3 and MSDS for safety and environmental compliance.

Questions about this item

How do I install the 54.58 x 33.69 x 4.3mm pack in my Zen Micro Photo, and what step causes the most trouble?

Open the player’s battery door, align the 3.7V pack’s contacts with the terminals, and press until the latch clicks; the common mistake is inserting the 41.0g cell upside-down so the connector pins miss the pads.

What maintenance or replacement will the 850mAh lithium pack need over time?

The built-in overcharge, over-discharge, over-voltage and short-circuit protection requires no user servicing; when run-time noticeably falls below the rated 830mAh capacity, simply swap in a new Estry pack.

What limit appears first during continuous playback on this 3.7V replacement?

The 850mAh capacity sets the runtime ceiling; under sustained load the player will shut down once the cell voltage drops to the protection circuit’s cut-off point.
