Direct replacement for Varta EZpack 1000

This Estry lithium battery matches the original 900mAh capacity and 3.7V voltage of the Varta EZpack 1000 series. It is built for users who need a drop-in power source for compatible devices without modifying the equipment. The single-cell pack delivers 3.33Wh of energy in a 64.94 x 36.7 x 6.6mm form factor.

Fits existing battery compartments

The cell slides into the same space as the original VKB-56446701099, 66380711099, 56456701099, VKB-66380711099 or LIP008 packs. No adapter cables or firmware changes are required because the connector layout and 3.7V nominal voltage are identical. Integrated protection circuitry guards against overcharge, over-discharge, over-voltage and short circuits.

Steady output under continuous drain

Protection circuits maintain stable voltage during prolonged use rather than only during brief peaks. The lithium chemistry supports consistent current delivery until the 900mAh reserve is depleted. Certifications including ISO9001, RoHS, CE, UN38.3 and MSDS confirm the pack meets safety standards for sustained operation. Not for devices that require higher capacity or a different voltage.
