Batteries do drop by a few volts over the run time so the oscillation does slow down a little as the battery gets closer to being depleted. However a Pogo with only one battery bar will still work great on most surfaces.
However the higher RPMs of a fully charged battery do make a noticeable difference when working on many carpets. When a customer intends to use the Pogo on carpet, they would be better off with an orange battery.
The battery factory only warranties them for one year however my experience indicates they will normally last for more than five years in home use.
