Titan is Screwfix’s own power-tool brand, and since the launch of the TXP one-battery platform its 18V batteries slide between drills, saws, mowers and trimmers alike. There’s one big catch that catches a lot of owners out — TXP batteries don’t fit older Titan tools at all. Here’s the full compatibility picture.
Quick Answer
- All Titan TXP 18V batteries fit all Titan TXP 18V tools — Screwfix sells TXP as a one-battery system across power tools and garden tools.
- The dual-voltage 18/36V TXP battery (TTT1240BAT) works in both 18V and 36V TXP tools, switching voltage automatically — it runs 8.0Ah at 18V and 4.0Ah at 36V.
- TXP is NOT backward-compatible. Screwfix states: “The new Titan TXP range is not compatible with previous non-TXP Titan tools and batteries.” If your Titan tool pre-dates TXP branding, TXP packs won’t fit it and your old packs won’t fit TXP tools.
Titan TXP Battery Line-Up
| Battery | Voltage | Capacity | Fits |
|---|---|---|---|
| TTI801BAT | 18V | 2.0Ah | All Titan TXP 18V tools |
| TTI803BAT | 18V | 5.0Ah | All Titan TXP 18V tools |
| TTB814ACC | 18V | 5.0Ah (battery + charger set) | All Titan TXP 18V tools |
| TTT1240BAT | 18/36V dual voltage | 8.0Ah @ 18V / 4.0Ah @ 36V | 18V, 36V and 72V (2×36V) TXP tools |
| TTB812BAT | 18/36V dual voltage | 8.0/4.0Ah | Discontinued — superseded by TTT1240BAT (refurb stock only) |

Chargers
| Charger | Charges | Notes |
|---|---|---|
| TTB804CHR standard charger | TXP 18V batteries | 2.4A — roughly 50 min for 1.5Ah, 60 min for 2.0Ah packs |
| TTB805CHR fast charger | TXP 18V batteries | Faster charge times on larger packs |
| TTB1242CHR dual-voltage fast charger | TXP 18/36V batteries | Sold solo or bundled with TTT1240BAT |
Note: TXP chargers only charge TXP batteries — they’re not compatible with older Titan packs.
Which Tools Take TXP Batteries?
The 18V TXP range covers combi drills (e.g. TTI884COM), impact drivers (TTI885IPD), jigsaws, angle grinders, multi-tools and reciprocating saws; the garden side runs 18V and 36V mowers, hedge trimmers, grass trimmers, pressure washers and the TT5MT36-Li garden multi-tool. The rule is simple: if the tool carries TXP branding, any TXP battery of the right voltage fits — and the 18/36V dual-voltage pack covers both.
Older Titan Tools — What Are Your Options?
If you own pre-TXP Titan 18V tools, you can’t move your batteries forward, and replacement non-TXP packs are increasingly hard to find new. Realistic options:
- Keep the old kit running while its batteries last, then treat a TXP kit (or another platform) as a fresh start.
- Third-party replacement packs for older Titan tools exist on marketplaces, but come with the usual quality and safety caveats — see are third-party tool batteries safe?
How Titan TXP Compares to Other Value Platforms
The closest comparison is Screwfix’s other own-brand platform: see Erbauer EXT battery compatibility for how the two ranges differ on voltage options and battery choice.
TXP competes directly with the other one-battery value systems we cover: Parkside 20V (Lidl), Einhell Power X-Change, Worx PowerShare and Erbauer EXT (also a Kingfisher brand, sold alongside Titan at Screwfix — but the two systems are not cross-compatible and no official adapter exists). For the wider market picture see our power tool battery compatibility chart.
Where to Buy
Titan TXP batteries and tools are sold at Screwfix (Titan is a Kingfisher own-exclusive brand; we found no Amazon UK listings for genuine TXP packs). Buy genuine packs only — the batteries carry a 2-year guarantee.
Frequently Asked Questions
Do Titan TXP batteries fit my old Titan drill?
No. Screwfix states the TXP range is not compatible with previous non-TXP Titan tools and batteries. Check your tool for TXP branding — no TXP logo means the old battery system.
Can I use the 18/36V battery in an 18V tool?
Yes — the TTT1240BAT switches voltage automatically and runs as an 8.0Ah pack in 18V TXP tools, and a 4.0Ah pack in 36V tools.
Are Titan and Erbauer batteries interchangeable?
No. Both are Kingfisher brands sold at Screwfix, but TXP and EXT are separate platforms with no official cross-compatibility.
Do other brands’ batteries fit Titan TXP tools?
No official cross-brand compatibility exists. Marketplace adapters are unofficial — they bypass the pack-to-tool protection design and typically void warranties. See our guide to power tool battery adapters before considering one.
