Cheryl, each Transformer dolly # PA66VR includes two 12-volt Interstate U1 deep-cycle batteries wired in parallel (12V, 2x the amperage). You’ll typically get around 30–40 minutes of continuous operation on a full charge - more than enough to maneuver several large trailers. The on-board charger plugs straight into a wall outlet, and you can check battery voltage on the built-in display. Parkit360 recommends topping off every couple months in storage to maximize lifespan.

Do you plan to leave it plugged in between uses, or will it be stored off-grid? That changes the best charging routine.
