In short
HiKOKI (formerly Hitachi Power Tools) is a Japanese trade brand with a strong UK reputation, particularly among first-fix carpenters and demolition trades who favour HiKOKI’s nail guns, circular saws, SDS hammer drills, and disc grinders. The 18V platform covers around 120 cordless tools in the UK.
Every HiKOKI 18V battery from the compact BSL1820M (2.0Ah) to the 5.0Ah BSL1850 fits every HiKOKI 18V tool, with backwards compatibility maintained since the Hitachi era. Most modern HiKOKI 18V tools are also compatible with the brand’s MultiVolt batteries (BSL36A18, BSL36B18), which automatically drop to 18V when fitted to an 18V tool, extending the runtime of existing 18V kit without buying separate batteries.
For tradespeople invested in HiKOKI cordless, the MultiVolt batteries are the smart upgrade path: same physical fitting as 18V packs, dual voltage capability, and full backwards compatibility with the existing 18V tool range.
Strengths
- Strong reputation in first-fix carpentry, demolition, and metalwork trades
- 120+ tools in the UK 18V cordless range
- Backwards compatible since the Hitachi era: every 18V battery fits every 18V tool
- Most modern 18V tools also accept MultiVolt batteries: natural upgrade path to 36V
- 3-year warranty as standard with an extended 5-year option when registered for brushless tools
- Up to 1,500 charge cycles on the BSL1850 thanks to multiplex protection circuit
Considerations
- Smaller tool range than DeWalt 18V XR or Makita 18V LXT: particularly in garden equipment
- HiKOKI brand awareness in the UK is lower than DeWalt or Makita despite the long Hitachi heritage
- Older Hitachi-branded tools and batteries are technically the same platform, but stocked support and warranty is more limited
- For maximum performance on modern HiKOKI 18V brushless tools, MultiVolt batteries are usually a better choice than standard BSL18xx packs
Questions
Which batteries fit HiKOKI 18V tools?
HiKOKI 18V tools take the HiKOKI 18V battery, and MultiVolt batteries also fit and run them at 18V.
Will a MultiVolt battery run my 18V HiKOKI tool?
Yes. A MultiVolt battery drops to 18V on an 18V tool, so you can share one battery type across your 18V and 36V HiKOKI tools.
Is HiKOKI the same as Hitachi?
Yes. HiKOKI is the former Hitachi power-tool brand, renamed in 2018. The 18V batteries carry the same fitment.
