On most household tools the machine is finished, because the cell is not user-replaceable. The exception is a tool that also runs plugged in — and three of the four clippers here state that they do.
No maker on this site publishes a replacement cell or a fitting procedure, which settles the first half of the question: there is no official route to a new battery on any of the 137 products here.
Corded operation is the practical safety net, where it exists. The Remington HC5811, the Philips HC5630 and HC7650 and the Remington MB5000 all state corded or battery operation. Those four outlive their cells.
One caution on that, because the listings do not spell it out: “mains or battery” means the tool can run from the cable. It does not guarantee it will still run with a cell that has failed rather than merely discharged — a dead cell can hold the circuit down. Check the manual before counting on it.
Cordless-only tools have no fallback. Not one of the eight shavers here states corded use, and neither do the body groomers. On those, the cell is the machine’s life.
The three things to do, in order
The warranty, if it is inside the term. Nine products here publish one, from two years to five — and a cell that has lost capacity gradually is usually outside the terms even so, because the tool has not failed. Which products publish what is worth reading before you assume.
Repair, where the maker offers it. One manufacturer on this site publishes a repair commitment: Rowenta states fifteen years of availability from 6,500 repair centers — on a styling brush with no battery at all, which is the irony of it. Nobody else states a network.
Recycling, which is not optional. A sealed lithium cell cannot go in curbside trash or curbside recycling: it is crushed in the truck, and that is how collection fires start. Retailer take-back and battery drop-off are the two routes, and how to dispose of an old tool sets them out.
What to weigh at purchase
A shaver whose heads are a published replaceable part is renewable at the cutting end and not at the power end. A clipper that runs corded is the reverse. Very few tools here are renewable at both — which makes the question less “will this last” than “which end of it will fail first”.
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.
