Replacement Battery for iRiver SlimX Players

This Estry IMP-900 cell is a direct replacement for the original nickel-metal hydride pack used in several iRiver SlimX portable audio players. It restores runtime for owners of the IMP-900, iMP-350, iMP-400, iMP-550 and MP-350 models who need a fresh power source.

1200 mAh Capacity and 1.2 V Output

The pack delivers 1.2 volts and 1200 milliampere-hours for an energy rating of 1.44 watt-hours. That capacity supports typical playback sessions but will not extend operating time beyond the player's original design limits. Heavy users may still require daily recharging.

Protected Cell with Certified Build

Integrated circuitry guards against overcharge, over-discharge, over-voltage and short circuits to preserve cell health. The battery carries ISO 9001, RoHS, CE, UN 38.3 and MSDS certifications, confirming compliance with international safety and environmental standards. No charger or extra accessories are included.

Questions about this item

Will this 1.2V 1200mAh pack run in my iMP-350 SlimX without modification?

Yes — it matches the original voltage and capacity for the iMP-350 SlimX and fits the 66.78 x 16.7 x 5.96 mm compartment.

How can I verify the pack is charging correctly after installation?

The player’s charge indicator should show normal progress and reach full within the usual cycle; the built-in protection prevents overcharge.

Does the package include a charger or only the 50.0 g battery?

Only the Ni-MH cell is supplied; a compatible charger must be purchased separately.
