The cell and its charging circuit are real cost, and in this category most tools include both — which is why price differences here usually come from the cutting element instead.
The pattern across our catalog is that battery and mains capability appear at every price point, so it is rarely what separates two machines.
What does separate them: the motor on clippers, the number of blades and the density sensor on shavers, the step size on trimmers, the number of attachments on kits, and the temperature range on heated tools.
The clearest example is the pair of Philips clippers here. Same wheel, same 28 lengths, same corded-or-cordless operation. The higher one costs roughly double for a two-sided blade and a self-clearing comb.
Battery specifications are the same on both. The blade is what you are paying for.
Check your own manual before you follow anything here. Temperatures, water ratings and supply voltages differ from model to model, and the maker’s own figures take precedence over anything written on this site. A supply of the wrong voltage is a failure rather than a slow charge, and the figure is printed on the tool — not inferred from a connector that happens to fit.
