Inadequate Power?

I have a mini Maestro 24-servo controller, currently hooked up to a 4 AA alkaline battery unit. I have 24 servos attached. It has functioned for about 20 minutes, but now several servos spin randomly upon powering up, even after a change of batteries.

From reading prior responses, it sounds like the servos are receiving inadequate power. What type of battery would be powerful enough to supply this arrangement? My understanding is that the servos could need as much as 24A in total.

Thanks in advance.

Yep, same old story. You should budget about 1 ampere per straining servo, for as many servos as will be moving at once. RC car batteries are designed for high current draw. I get mine from
