On a rechargeable tool, no — the cell is sealed and not designed to be replaced, and that is usually what ends the machine. On the five trimmers here that take an AA or AAA, the answer is the opposite: the cell is the one part you can always replace.
No maker here publishes a replacement cell or a fitting procedure for a rechargeable tool — not one of the 137 products.
The exception is a whole half of one shelf, and it is worth knowing before buying. Five of the twelve nose and ear trimmers run on a replaceable AA or AAA: the Braun EN21, the Philips NT5650, the Norelco at $22, the ConairMAN at $13 and the Zorami at $10. On those the cell is a consumable you buy anywhere, so the tool has no battery-shaped end of life at all — which is the argument for a cell over a charge on a tool used for two minutes a week.
What makers do publish is replacement CUTTING parts, and in detail: Philips states shaver head compatibility as a code pattern, and the Panasonic Pro X blade at $70 names the fifteen clipper references it fits. That asymmetry is the practical shape of repairability here — the end that wears fastest is the end you can buy.
One exception in spirit: Rowenta publishes a fifteen-year repairability commitment from 6,500 repair centers on its hot air brush — a tool that has no battery at all, which is the irony of it.
If a battery has failed and the tool is otherwise sound, the options are the warranty while it lasts and, beyond that, replacement.
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.
