Keeping a couple of spare packs in the van makes a big difference if you run Erbauer’s EXT 18V cordless tools. These 4.0Ah Li Ion batteries sit in the middle of the range, competing with similar-capacity packs from the likes of Einhell and Ryobi, and they’re aimed at trade and serious DIY use where downtime costs time.
Who is this twin pack for?
If you’re regularly on site or in the workshop, two batteries let you rotate between tool and charger, so you can keep drilling, cutting or fastening without stopping. The 4.0Ah capacity is a sensible balance, giving longer runtime than compact packs without the extra bulk of high-capacity options. Keep Cool Technology is there to manage heat under load, which helps maintain performance and can support battery longevity over repeated cycles.
- Charge indicator: quick check before you start a job, so you’re less likely to get caught out mid-task.
- 18V EXT compatibility: intended for use across Erbauer EXT 18V cordless tools, so one battery type covers multiple tools.
