Battery mowers
Which twin-pack battery mower is specified better?
Both of these make 40 volts out of two 20 volt packs, both are supplied with two 4 Ah packs and a twin charger, and both carry about 160 watt-hours of energy. That last figure is the one that decides how much lawn gets cut on a charge, and it is identical. What differs is what each maker chose to publish around it.

| Battery supplied | Two 20 V 4.0 Ah packs and a dual charger, about 160 Wh | Two 20 V 4 Ah packs and a twin charger, about 160 Wh |
| Stated area | Up to 500 m² with the supplied packs | Not published |
| Cutting heights | 7 heights on one lever; range not published | 25–75 mm, central adjustment |

A tick means one listing published something the other did not, or published a better figure. It does not mean the product is better, and the column is not a score out of anything: a maker who says less loses lines here without losing a comparison. The two verdicts below are where the page is settled.
WORX publishes the area its own batteries will cover — 500 m² on the two supplied packs — which is the figure a battery mower is actually bought on, and almost nothing on this shelf gives it. Its platform is also the broader one, spanning three voltages, which matters because the expensive part of a cordless tool is the pack and not the tool.
FUXTEC is 3 cm wider, publishes a cutting-height range in millimetres rather than a step count, and publishes a 40 litre catcher. Those are three concrete numbers against one, and the height range is the one that decides whether a mower can cut a lawn at the height you want rather than at one of seven unnamed positions.
Because volts and amp-hours on their own are misleading. Energy is volts times amp-hours, and two 20 V 4 Ah packs come to about 160 watt-hours on both of these machines. That is the fuel tank, and it is identical — so any difference in area covered comes from the cutting width and the motor, not from the batteries.
It covers more ground per pass and it draws more current doing it. Forty-three centimetres against forty is about 8 per cent more lawn per pass from the same 160 watt-hours, which is why the wider machine does not publish an area figure and the narrower one does.
The heights. A step count says how many positions there are and nothing about where they are, and a mower whose lowest setting is 40 mm is a different tool from one that starts at 25. The competing listing publishes 25–75 mm, which can be checked against a lawn.
40 cm, 2× 20 V 4 Ah, load-sensing, 7 heights, 500 m² stated
A load-sensing motor that raises power in thick grass, a deck shaped to cut close to fences, and a stated two-hour charge for both packs.
Best for: A medium lawn with a lot of boundary, where the strip left for the shears is the annoyance
43 cm, 2× 20 V 4 Ah, twin charger, 40 L, 25–75 mm
Two 4.0 Ah packs and a twin charger with a 43 cm deck: the most energy in a complete kit here, and the packs charge in parallel.
Best for: A medium to large lawn where the whole job should finish in one session
The live figure beside a product went and asked the shop for it the moment this page opened; any amount written into the text has not moved since the sentence was drafted, and it is the first of the two that counts.
