Erbauer is Kingfisher’s mid-range trade brand (sold at Screwfix and B&Q), and its EXT battery system spans a big 18V tool range plus 36V garden machines via dual-voltage packs. This chart covers what fits what — including the 12V catch and the Evolution cross-over question.
Quick Answer
- All Erbauer 18V EXT batteries fit all Erbauer 18V EXT tools — drills, saws, grinders, sanders, multi-tools and more run “from one powerful lithium-ion battery”.
- The 18/36V dual-voltage EXT packs (3.0/6.0Ah and 4.0/8.0Ah) are officially “compatible with all cordless 18V, 36V and 72V (2×36V) Erbauer EXT tools” — one battery for the drill and the lawnmower.
- The 12V EXT range is separate. Erbauer’s 12V tools (ECD12-Li-2, EID12-Li-2 and friends) use their own 12V packs (EHPB12-Li-3) and charger — 12V and 18V packs do not interchange.
- Erbauer EXT and Titan TXP are not cross-compatible, even though both are Kingfisher brands sold at Screwfix.

Seen an EBAT18-Li code on an older pack? Those are earlier EXT 18V part numbers (the 5.0Ah EBAT18-Li-5 still appears on Screwfix’s EU shop). They belong to the same EXT 18V system; current UK listings use the ERI-series codes.

Which Tools Take EXT 18V Batteries?
The 18V EXT range covers combi drills (ECD18-Li-2), impact drivers (EID18-Li), circular/reciprocating/mitre saws, angle grinders, planers, sanders, multi-tools, paddle mixers, vacuums, radios and torches, plus multi-tool kits like the E18-6KA 6-piece. On the 36V side, EXT dual-voltage packs power the garden range including the 41cm brushless lawnmower. If the tool says EXT and matches the battery voltage (or the battery is dual-voltage), it fits.
The Evolution Question
Evolution Power Tools sells 18V batteries (e.g. the 8Ah R18BAT-Li8) that Evolution itself states are “compatible with Erbauer 18V EXT cordless tools”, using an “Erbauer compatible connector”. Note carefully: that is Evolution’s claim, not Screwfix’s or Kingfisher’s — we found no reciprocal statement from Erbauer’s side, so running Evolution packs in Erbauer tools (or vice versa) is at your own risk and may affect warranty cover. It is, however, the only manufacturer-stated cross-over in this ecosystem.
How EXT Compares to Other Value Platforms
Erbauer EXT sits alongside Titan TXP (Screwfix’s budget stablemate — not cross-compatible), Parkside 20V, Einhell Power X-Change and Worx PowerShare. For the full market view see the power tool battery compatibility chart.

Frequently Asked Questions
Do all Erbauer batteries fit all Erbauer tools?
Within a voltage family, yes: every 18V EXT pack fits every 18V EXT tool, and the 18/36V packs fit 18V, 36V and 72V (2×36V) EXT tools. The 12V EXT range uses its own separate packs.
Are Erbauer and Titan batteries interchangeable?
No — EXT and TXP are separate platforms with no official cross-compatibility, despite both being Kingfisher brands.
Can I use Evolution batteries in Erbauer tools?
Evolution states its 18V EXT-fit batteries are compatible with Erbauer 18V EXT tools; Erbauer/Kingfisher publishes no reciprocal statement. Treat it as an unofficial (if manufacturer-made) option and weigh the warranty implications.
What’s the warranty on Erbauer batteries?
Erbauer packs typically carry a 1-year guarantee (shorter than Titan TXP’s 2 years) — check the current listing for the pack you’re buying.
