About the Unitree H2 Battery
The Unitree H2 battery is the official quick-release power pack for the H2 humanoid: a 15Ah (972Wh) premium lithium pack with low internal resistance, running up to 75.6V and specified for about 3 hours of operation per charge.
It is a smart battery: a charge-level display on the pack itself, cell balancing, and storage self-discharge control that brings a stored pack down to a safe level on its own, backed by overcharge, over-discharge and short-circuit protection.
The pack is tool-free and quick-release, so teams that run the H2 through back-to-back demos, data collection and gait sessions keep a spare Unitree H2 battery on rotation rather than waiting on the charger.
The Official Replacement Battery for the H2
This Unitree H2 battery is the factory pack for the H2 humanoid: a quick-release smart battery specified in the official H2 configuration at 15Ah (972Wh) with a 75.6V maximum. It is sold as a single replacement pack, so one listing covers a failed pack or fills out a rotation.
Swapping is tool-free — release, lift, seat the fresh pack — which is what keeps a mid-session battery change a bench-side job rather than a maintenance task.

Unitree H2 Battery Life: About 3 Hours per Charge
The official H2 specification lists battery life at about 3 hours per charge from the 972Wh pack — a step up from the previous generation's 864Wh system. Runtime moves with the workload: continuous walking, loaded tasks and dynamic demos draw more than standing poses or light development sessions, so plan around a range rather than a fixed number.
Charging runs through the charger included with the H2, and a spare pack on the bench turns the 3-hour figure into a planning number instead of a hard stop.
Shipping, Quality Guarantee & Battery Care
We ship lithium batteries worldwide in UN38.3-compliant packaging via DHL or FedEx. Battery-only parcels travel as regulated air cargo, so delivery can take a few days longer than standard shipments; we confirm the exact transit time with your quote.
Every Unitree H2 battery is 100% quality-inspected before it ships, so it arrives in perfect working order. If you keep a spare in storage, storage self-discharge brings it down to a safe level automatically, so the pack stays healthy between sessions.
