yeah but not immediately restart like mine does. every single battery disconnected shows 5.7 volts, it was 6.2 about a month ago, but I used a good bit since. Those charger wires are totally rusted, explains why the charger was getting super hot, probably overheating and shut off only to repeat the cycle. similiar to my truck batteries. one cable was loose and it was putting out 18v on one side to get the other side up. Now with that being said, I never did bother to put a multi meter on these scissor lift batteries to see what the onboard charger was doing. They were boiling for sure though, you could hear and smell it. Although that is supposed to be somewhat normal i've heard.my friend just bought a used lift with the same 4 series battery configuration. Chances are one battery is weaker than the rest. the big charger will have to kick on and off, that’s how they work. some of the batteries are topping off while others still need more. You can try to charge them individually and it will help but you’ll still be limping along.
