Safety & Liability Notice

Batteries store large amounts of energy and contain hazardous materials. This notice summarises the main hazards covered on this platform and states where responsibility lies. It is a general notice, not a safety procedure for your installation.

At a glance: Work on batteries only if you are qualified to do so, always follow the battery manufacturer's documentation and your jurisdiction's regulations, and where a situation is outside your competence or is already dangerous, stop and get a qualified person or the emergency services involved. Nothing published on World Battery Hub is a substitute for that.

1. Responsibility lies with the person doing the work

Sizing, installing, charging, discharging, testing, transporting, storing and disposing of a battery are activities for a competent person, carried out under the manufacturer's instructions, the applicable standards and local law. Information published on this platform is general reference material; it is not a work instruction, a risk assessment or a safety certification for any specific battery or installation.

Where our content and the manufacturer's documentation differ, the manufacturer's documentation and the applicable regulations prevail.

2. General electrical hazards

  • High short-circuit currents. A battery can deliver very high current into a short circuit. Remove metal jewellery and watches, use insulated tools, and never lay tools or metal objects across terminals.
  • Arc, heat and fire. A short circuit can arc, melt metal and ignite surrounding material. Work in a ventilated area away from ignition sources.
  • Series strings. Higher-voltage battery strings (for example in solar, telecom, UPS and traction systems) carry correspondingly greater hazards. Treat any such system as live.
  • Personal protective equipment. Eye protection and appropriate gloves are basic precautions; for lead-acid work, acid-resistant protection and an eyewash or clean water supply should be available.

3. Lead-acid batteries

  • Sulphuric acid. The electrolyte causes severe burns and permanent eye damage. Handle flooded batteries upright, avoid splashing, and flush any contact with copious clean water — seek medical attention for eye contact.
  • Hydrogen and oxygen. Charging can release explosive hydrogen. Never charge or work on a lead-acid battery near sparks, open flame, or equipment that can arc, and ventilate the space. Never smoke nearby.
  • Weight and lifting. Batteries are heavy and awkward — use proper lifting technique or equipment, and secure them against movement.
  • Vent caps and valve-regulated types. Do not open, tilt beyond the manufacturer's limits, or obstruct the vents of a battery, including AGM and gel types.

4. Lithium-ion and lithium-metal batteries

  • Thermal runaway. A damaged, overcharged, overheated, internally shorted or defective lithium cell can enter thermal runaway — a self-sustaining reaction producing intense heat, fire and toxic gas, which can spread to neighbouring cells and reignite after apparent extinction.
  • Mechanical damage. Puncturing, crushing or dropping a lithium cell can trigger internal short circuits, sometimes with delayed onset. Do not use a cell that has been damaged.
  • Swelling, smell, heat or noise. A swollen, hot, hissing or leaking cell is an immediate hazard. Do not charge or use it; isolate it, keep it away from combustible material, and follow the manufacturer's and your fire service's guidance.
  • Charging. Use only a charger specified for the cell chemistry, voltage and pack configuration. Overcharging a mismatched pack is one of the most common causes of failure.
  • In an emergency. Raise the alarm and call the emergency services — do not attempt to fight a large lithium battery fire, and do not handle a smoking, hissing or burning pack.

5. Transport

Lithium cells and batteries are regulated dangerous goods for transport (UN 3480/3481 and related packing instructions), and lead-acid batteries are also classified for transport (UN 2794/2800). Air, sea and road shipments are subject to state-of-charge limits, packaging requirements, labelling and documentation. Shipping a battery that is damaged, recalled or unapproved may be prohibited. Confirm the requirement that applies to your shipment and route before dispatch.

6. Storage and disposal

  • Store batteries according to the manufacturer's temperature and humidity limits, protected from mechanical damage, water ingress and unauthorised access.
  • Do not store damaged lithium cells with combustible material, and keep them away from occupied spaces where your risk assessment requires it.
  • Never dispose of batteries in household waste. Lead-acid batteries and lithium batteries are subject to recycling requirements, and the applicable rules vary by country and region — use an authorised recycler or take-back scheme.

7. No liability for use or misuse

To the fullest extent permitted by applicable law, World Battery Hub and its operators accept no liability for any injury, death, property damage, equipment damage, loss or cost arising from the handling, installation, charging, discharging, testing, transport, storage or disposal of any battery, whether or not it follows information published on this platform. See our Disclaimer for the general limits of what we claim.
