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.

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.
