Explosion-proof and intrinsic safety
Underground environments have clear explosion-proof and intrinsic safety requirements, so the plan is confirmed against your equipment rating.
Mining and underground battery packs: lamps and explosion-proof power
Miner's cap lamps, intrinsically safe power and underground emergency power must work reliably in harsh underground conditions. Explosion protection, wide temperature and high reliability are the three requirements.
Requirements
What this application demands of the pack
These are the electrical and mechanical points that matter in this application.
Wide temperature and high reliability
Underground temperature and humidity are special, so reliable operation and wide-temperature behaviour are assessed together.
Long standby and emergency output
Miner's lamps and emergency power stand by for long periods yet must deliver at the critical moment.
Scope

Checklist
What we need from you
Give us these and while meeting your performance needs we pick the most cost-effective option for you.
| Item | What to tell us |
|---|---|
| Equipment type and use | Miner's lamp / intrinsically safe power / underground emergency power / mining luminaire / rubber-tyred vehicle |
| Explosion-proof rating | The explosion-proof and intrinsic safety rating of your equipment and the relevant code |
| Voltage and capacity | Device voltage platform and required capacity |
| Installation environment | Underground temperature, humidity and protection requirements |
| Certification requirements | Target market and the certification items needed |
| Capacity & discharge | Built from 0.1 Ah to 600 Ah to your requirement — common levels such as 10 Ah, 20 Ah, 50 Ah, 100 Ah and 200 Ah are all confirmed per model; continuous and peak rates are matched to the duty cycle |
The above describes the general matching logic only. The final selection is made by us — your requirements come first, and we work to reduce your cost as far as safety allows.
FAQ
Questions about mining and underground packs
Which form factors are available for mining packs?
Two: prismatic and cylindrical. Prismatic suits intrinsically safe and emergency power; cylindrical suits small devices such as miner lamps. The choice follows your equipment and explosion-proof rating.
How is intrinsic safety handled?
The plan is confirmed against your equipment explosion-proof and intrinsic safety rating and the relevant code, with the chemistry and structure assessed together and working with the unit to meet the explosion-proof requirement.
Can it be built for underground conditions?
Yes. Tell us the underground temperature, humidity and protection requirements, and we will assess from both the chemistry and the structure so the pack runs reliably underground.
How is certification handled?
We hold 17 certifications and reports including CE, IEC 62133, UL 2054, RoHS and REACH. Mature models come with existing certificates, provided directly; newly customised models are checked item by item against your target market and specifications. New certifications are handled end to end by our team, with testing costs and timelines set out in the proposal for your confirmation before anything starts.
