A Challenge cordless grass trimmer 18V may appear as a bare tool, a battery bundle or an Xtreme-branded product. Those names alone are not enough to establish that the charger, battery or replacement head will fit. Find the model code on the product label or paperwork before comparing offers.

Common questions

Questions before you buy

Are Challenge 18V trimmer batteries interchangeable?

Compatibility is model- and battery-platform-specific. Confirm the exact tool and battery codes in the manufacturer documentation; voltage by itself does not guarantee compatibility.

Does a Challenge 18V cordless grass trimmer include a charger?

Some listings are bare tools and others are kits. Check the product code and package contents before ordering a charger separately.

Where can I buy Challenge cordless trimmer spares?

Search using the model code and the part number shown in the manual or parts diagram. This avoids ordering a similar-looking but incompatible spool or guard.

What is the Challenge Xtreme 18V cordless grass trimmer?

Challenge Xtreme is wording used for a range of garden tools. Identify the exact trimmer model, then check its own specifications and instructions.
