One single battery platform · runtime written as a division
Search by platform

Tell us which battery you own, not which tool you want.

Search by voltage, by battery model or by tool name. If you already own a battery, start from it.

The voltage and the amp-hours are written on the battery, on the side that slides into the tool.

One battery, every tool

The platform everything we sell runs on

The battery is the expensive part. That is why we also sell the tools bare: if you already own one on this platform, you move it from tool to tool.

The voltage on the box is the maximum, off load. The one on the battery plate is the nominal one, a little lower — we work with the one written here.

Check before you order

Will your battery work on these tools?

The same platform does not mean every battery drives every tool: a brushcutter pulls far more than a hedge trimmer. Write below how many amp-hours yours has.

  • Hedge trimmerWorks with the small one too; the weight in your hand matters more. 2 Ahminimum required
  • Leaf blowerPulls hard, but in short bursts. 2 Ahminimum required
  • Lawn mowerWith 2 Ah you mow a small garden, once. 4 Ahminimum required
  • BrushcutterFor thick grass and weeds, go straight to 6 Ah. 4 Ahminimum required
  • ChainsawThe biggest draw in the range. 5 Ahminimum required

The minimums come from the maker’s data sheets, checked by us on the bench.

“Too small” does not mean the tool will not start: it means it cuts out on protection under heavy load and the battery runs hot.

How long a battery lasts on this tool

The draw is the one we measured under normal work — not idling and not flat out.

Wet grass, thick hedges and blunt blades pull the figures above down. They are a reference point, not a promise.

How long it stays plugged in

The figures are for the charger written below, not for any charger that fits the slot.

  • Do not leave it flat over winterA battery left empty for five months loses capacity and never gets it back. Leave it at half and check it once a month.
  • Do not charge it straight after workGive it fifteen minutes to cool down. Charging a hot battery shortens the life of the cells.

In frost and above 35 °C the charger waits until the battery is back in range. Then the figures go up.

How we choose

You pick the tool around the battery, not the other way round

The battery is half the price and it also decides how long you work without a break. That is why every figure on this site starts from it.

Platform

One single platform in the shop

We keep one platform, not four. The battery you buy today also fits next year’s tool, and the charger stays the same.

Battery life

We write the division in plain sight

The battery energy divided by the tool draw. The figure is not an “up to”, it is the result of a division you can check.

Without a battery

The same tool, two prices

Every tool is also sold bare. If you already own a battery, you do not pay twice for the expensive part.

One single platform

The same battery on every tool.

Runtime worked out

Watt-hours divided by the draw.

The minimum required, written down

On every tool, on every row.

No stale petrol in the tank

Starts at the first press.

Questions before you order

What people ask us most often, on the phone.

Will my battery from another brand fit here?
No. The slot and the electronics differ from brand to brand, and the adapters sold online void the warranty and can set the cells on fire.
What do “18 V” and “4 Ah” mean?
Volts are the voltage, amp-hours are the amount of energy. Multiplied, they give watt-hours — the figure we use to work out the runtime on each tool.
Does a bigger battery make the tool more powerful?
No, it makes it last longer. Power comes from the motor and the voltage. What changes is that a big battery stops cutting out on protection under heavy load.
Is petrol better?
For all-day work, yes. For a garden mown once a week, no: a battery starts at the first press and you are not left with stale petrol in the tank.
How do I store it over winter?
At half charge, somewhere dry, between 10 and 20 °C, checked once a month. Not empty and not full.
How many years does a battery last?
It is measured in charge cycles, not years. For every battery we write how many cycles the maker states, with the source next to the figure.
