What is the battery life of Optimus?
Tesla publishes a capacity, not a battery life. DEPLOY's record holds Tesla's published battery capacity for Optimus, 2.3 kWh at 52 volts on the first generation, and no runtime at all. Capacity is how much energy the pack stores; battery life is how long a charge lasts doing work. Other robot makers publish the second figure. On this record, Tesla does not.

The honest answer is that the number most people are looking for does not exist on DEPLOY's record. Tesla has published a battery capacity for Optimus, 2.3 kWh at 52 volts for the first generation, and that figure is on the registry. No hours-per-charge figure is.
Those two things are often treated as the same and they are not. Capacity is how much energy the pack holds. Battery life is how long that energy lasts, which depends entirely on what the robot is doing: standing still, walking, or lifting a load draw very different amounts of power. A capacity figure alone cannot be converted into a runtime without knowing the draw, and Tesla has not published one on this record.
You will find a figure of roughly eight hours repeated in a lot of places. Treat it carefully. It does not come from anything on DEPLOY's record, and this page will not repeat a number it cannot trace to a source.
What makes the gap clear is that publishing a runtime is an ordinary thing for a robot maker to do. Every robot on the record that states one is set out on this page, each figure attributed to the maker that published it, so you can see the band a humanoid runtime currently sits in and judge the missing Optimus figure against it.
Capacity is on the record. Runtime is not.
The whole answer in one line: these are two different numbers, and only the first one exists here.
- What the record holds
- 2.3 kWh, 52 V (Gen 1 published spec) (battery capacity, Tesla's own published spec, read from the Optimus registry record)
- What it does not
- No runtime. A query for reviewed runtime specs on this record returns 0. Hours per charge is not a figure the registry holds for Optimus.
Why one does not give you the other
Each column is attributed to what it actually is: a published spec, a definition, and the state of the record.
A capacity, 2.3 kWh at 52 volts
The first-generation Optimus battery capacity is on the record as Tesla's own published specification. It describes how much energy the pack stores, and it is a maker's figure rather than an independent measurement.
A runtime, which is a different quantity
Battery life is how long a charge lasts in use. Converting capacity into runtime needs the robot's power draw, which changes with the task, so the two figures are not interchangeable and one cannot be derived from the other.
No runtime on the record
A query for reviewed runtime specs on the Optimus record returns nothing. Until Tesla publishes one and it is recorded, the honest answer is that the registry does not hold this figure, and the comparable makers' figures below are the closest available context.
What other makers publish
Every robot on the record that states a runtime, longest first, each figure attributed to the maker that published it. The humanoid comparisons are the relevant ones: NEO at 4 hours and Noetix N2 at 2 hours.
- Zoox Robotaxi: 16 hours
Autonomous vehicle. The figure is the maker's own published specification, recorded on the Zoox Robotaxi registry entry rather than measured by DEPLOY.
- NEO: 4 hours
Humanoid. The figure is the maker's own published specification, recorded on the NEO registry entry rather than measured by DEPLOY.

How we know this
Optimus's battery capacity is read live from its verified record on the DEPLOY registry, and the absence of a runtime is a query result rather than an assertion. Every comparison figure below is read from that robot's own reviewed spec row and attributed to the maker that published it. Here are the sources behind them.
Every runtime on this page is a manufacturer's published figure, marked as a maker's claim rather than a DEPLOY measurement, because that is what the underlying records say they are. DEPLOY scopes the answer to its record and will not repeat a widely-circulated number it cannot trace to a source.
