I had to manually move my Stannah 600 Starilift, purchased in 2018 but the batteries were dead. And I couldn't find anything online that showed how to do this! So I made one once I figured it out! Hope it helps!
sorry but it"s not that simple to remove the rear battery, looks to me like the circuit board that sits on top has to be removed to get access, I gave up and called the service engineer,
