At 1A+ load, they would sag below 5V even with large cells. Figure 1 V/cell in operation, so 5V batt would be right, but then regulator might be needed when batt is fresh charged. NiCad and NiMH would be quieter than lead acid. They will self discharge much faster than lead acid though. Cells that will provide high current peaks quickly will self discharge more quickly. Optima makes a spiral lead acid battery that has a higher density and discharge than a plate batt. It might be less chemical noise for given discharge rate. Plus it is totally sealed, safer for indoor use. They make a 6V version. LiPO cells are 3.6V nominal, but they hold voltage flatter than the other rechargeables, but safety is more of a concern because they will blow up if overcharged. I wonder if SB will start/run at that low voltage?
