Robots with swappable batteries: 16 models that do not wait to charge
16 robots with a swappable or hot-swap battery: humanoids, quadrupeds, delivery robots and exoskeletons. Swap times from 5 seconds to 3 minutes, runtime up to 24 hours.

Battery runtime is the first limit every pilot runs into. A robot whose battery can be swapped instead of charged works in shifts: one battery in the robot, the other on the charger. This roundup collects 16 models in the Robolupa catalogue whose data explicitly mention a swappable battery or hot-swap. It is a list based on explicit statements, so it is certainly incomplete; a missing model only means a missing mention. Tips on reading battery parameters are in “How to Read a Robot Datasheet”.
The largest group, 10 entries, is humanoids, plus 3 quadrupeds, one service robot and two exoskeletons, including the Myomo MyoPro 2x with a swappable battery. Swapping is sometimes automated. The UBTech Walker S2 changes its battery on its own in 3 minutes (a dual-battery system), the Atlas in under 3 minutes, and the REX G1 claims a swap in 5 seconds without switching the robot off. The Unitree G1 uses a 9,000 mAh pack with quick release, and the Unitree A2 has two hot-swap batteries and 5 hours of runtime. The second battery for the DEEP Robotics Lynx is an extra expense.
What about runtime? For 13 of the 16 entries the database gives a figure: 1.5 to 24 hours, median 4. For the humanoids (9 entries with data) the median is also 4 hours, while across all 36 humanoids with that value it is 3 hours. The record of 24 hours belongs to the delivery robot Pudu HolaBot, which carries up to 60 kg and has a swappable battery. The NEURA 4NE-1 Gen 3.5 claims up to 8 hours thanks to swappable batteries, but it is at pre-order stage with an unverified payload. The Unitree G1, the Noetix N2 and the quadruped ANYbotics ANYmal X give 2 hours. The database gives battery capacity for only a small share of models, so a rigorous watt-hour comparison is impossible today.
Status: 9 models are on sale, 2 are prototypes, 3 pilots, 1 pre-order and one has been withdrawn (the Sarcos Guardian XO, which had three swappable lithium-ion batteries and was offered only as a service). Four are available in Poland: the Pudu HolaBot, Unitree G1, Unitree A2 and DEEP Robotics Lynx. The rest include the Apptronik Apollo (about 4 hours), the MenteeBot V3, the LimX Oli, the Agibot A2 Ultra and the Myomo MyoPro 2x.
Who is it for? Anyone planning two- or three-shift operation, for example in a warehouse or on a factory floor; see “Humanoid Robots in Factories 2026”. When you calculate, remember that the second battery and a charging station are a cost, covered in “Humanoid Robot TCO: How to Calculate Total Cost”. Manufacturers rarely give the price of a spare pack or its charging time; the exception is the Pudu HolaBot with 4.5 hours of charging, so always plan swapping in pairs: one pack in the robot plus one on the charger.

Frequently asked questions
Which robot swaps its battery fastest?
The manufacturer of the REX G1 claims a swap in 5 seconds without switching the robot off. The UBTech Walker S2 and Atlas quote about 3 minutes or less, with the battery swapped autonomously.
How long do these robots run on one battery?
For 13 of the 16 models the database gives a runtime: 1.5 to 24 hours, median 4. The longest, up to 24 hours, is the Pudu HolaBot delivery robot; humanoids usually fall within 2 to 4 hours, and the Neura 4NE1 claims up to 8.
Does a robot missing from the list have no swappable battery?
No. The list is based on explicit statements in the model data. Many manufacturers do not say whether the battery can be swapped, so ask about it directly before buying.
Which of these robots are available in Poland?
The database confirms four: the Pudu HolaBot, Unitree G1, Unitree A2 and DEEP Robotics Lynx. The others are available only to order from the manufacturer or have not yet reached general sale.
Where this list comes from
The collection is generated from the Robolupa catalogue by a fixed criterion described in the introduction and changes with the data. Prices in zloty come from Polish shops or are converted from foreign currencies (marked with an asterisk). How data are collected and checked is described on the page Methodology.
