Only within the same platform, and a platform is a brand’s naming convention rather than a standard. There is no common pack in cordless garden tools and there never has been.
What a platform is
A badge. A manufacturer picks a name for its battery ecosystem, uses the same physical interface across its range, and the badge is the promise that any tool in the range takes any pack in the range. Some of these ecosystems are genuinely large; some span more than one brand where manufacturers have agreed to share an interface.
None of it is standardised by anybody. There is no document that defines a garden tool battery interface the way there is one for a mains plug. Two packs with the same voltage, the same chemistry and the same capacity are not interchangeable if the rails and the contacts differ, and they usually do.
Where the real cases are
Same brand, same platform: the intended case, and it works.
Same brand, different platform: common and confusing. Several manufacturers run two or three ecosystems at once, often with overlapping voltages, and a pack from one will not seat in the other.
Shared alliances: a small number of interfaces are shared across several brands by agreement, and packs move between them. Where that applies, the makers say so on the box, and this site prints what the listing states.
Third-party replacements: widely sold for the large platforms. They fit. What is inside differs, and the listing usually does not say.
Adapters: they exist for most popular combinations. They solve the mechanical problem and leave the electrical one, and a pack whose protection circuit is talking to nothing is being used outside what its maker tested.
What this costs on a mower specifically
A mower is among the hardest loads in a cordless range: sustained, high, and often at the point where a pack’s protection cuts in. It is the machine where a marginal pack shows up first.
How this site handles it
Cordless pages here name the platform exactly as the listing does, print the voltage and capacity together, and state whether the machine is sold with a pack at all. No page here asserts that a pack from one platform fits a machine from another, and where a listing claims compatibility, the page attributes the claim to the seller.
Wherever this page and the maker’s own documentation disagree, the documentation wins. Every cutting width, cutting height, stated area, pack capacity, flow rate, head, sound level and application rate on this page comes from the maker’s own published figures, with the unit as printed and the source named. None of it is measured here, and no figure is converted into another convention, because a converted number is a different number. And the division this page refuses to hide: a runtime is pack energy divided by a load, and the load is your grass. A published figure is a bench result obtained on short, dry grass at a middle setting, with no uncertainty attached and no obligation to state its conditions. This page prints capacity and platform voltage together, and reports any runtime as the manufacturer’s.
The questions that keep coming in
Are the third-party replacement packs any good?
They vary enormously and the listing rarely says which cells are inside. What they share is that the machine’s maker publishes no trial of them on the machine, which matters for a tool that draws hard and gets hot.
Do adapters between platforms work?
Mechanically, often. Electrically they connect a pack to a machine that was never designed for it, bypassing whatever communication the pair was meant to have. Nothing about the physical fit tells you the pack’s protection will behave.
