Direct replacement for Shark cordless vacuums

The Estry V1725H is a nickel-metal hydride pack rated at 4.8 volts and 1500 milliampere-hours, delivering 7.2 watt-hours of energy. It fits Shark models V1720, V1725 and V1725H and replaces part number X9725H. The pack measures 78.0 by 45.0 by 44.4 millimetres and weighs 320.0 grams.

Upgrades from a depleted original pack

Swap this cell in when the factory battery no longer holds a charge or shows reduced run time. The jump is worth it if the vacuum powers off early or the charge indicator drops quickly during normal cleaning. Built-in protection guards against overcharge, over-discharge, over-voltage and short circuits to extend service life.

Steady output through a full cleaning cycle

The chemistry maintains a stable voltage curve so suction stays consistent from start to finish rather than fading after a few minutes. Certifications include ISO 9001, RoHS, CE, UN 38.3 and MSDS, confirming the pack meets international safety and transport standards for sustained household use.

Questions about this item

What are the dimensions of the Estry V1725H battery so I can check it fits my vacuum?

The pack measures 78.0 x 45.0 x 44.4 mm and weighs 320.0 g, matching the original Shark V1725H / V1720 / V1725 battery cavity.

How do I install the replacement and what step is often missed?

Slide the 4.8 V 1500 mAh pack into the compartment until the latch engages, then run a full charge cycle before first use — skipping that initial full charge is the common mistake.

What maintenance or replacement will this Ni-MH pack need over time?

Expect gradual capacity loss after several hundred cycles; when run-time drops noticeably, replace with another 4.8 V 1500 mAh pack (part X9725H) to restore original performance.
