Where do the lithium-ion batteries of counterbalance forklifts go at the end of their life?

In the world of industrial logistics, one of the biggest trends of recent years has been the spread of lithium-ion battery technology. More and more companies are replacing their old counterbalance forklifts powered by lead-acid batteries with modern, maintenance-free lithium-ion versions. And for good reason: a longer service life, faster charging and greater efficiency are all major advantages.

But what happens to these batteries when they can no longer be used?

More and more batteries, more and more responsibility

The rise of lithium-ion technology is a huge opportunity for industry, but it also brings a new kind of challenge: how do we handle used or damaged batteries safely and sustainably?

Both European Union and Hungarian regulations stipulate that every manufacturer and distributor of industrial lithium-ion or lead-acid batteries is responsible for the product's entire life cycle – including collection, transport, storage and recycling.

Lithium-ion batteries are not just hazardous waste – they are also valuable resources

A worn-out battery has not necessarily lost all its value. Although the lithium-ion batteries of counterbalance forklifts lose capacity over time, many of their components can be recycled with the right handling and technology.

But the process is not as simple as with lead-acid batteries:

  • Lithium-ion battery cells come in many different chemistries (e.g. NMC, LFP), so their processing cannot be standardised.
  • The recoverable materials – such as lithium, nickel, cobalt and aluminium – are present in small quantities, and extracting them is expensive.
  • If damaged, lithium-ion batteries can be prone to thermal runaway, which can cause a fire or even an explosion.

That is why strict safety regulations also apply to their transport and storage. They may only be handled by properly trained specialists, using special fire-resistant packaging and ADR-licensed carriers.

Battery recycling: lead-acid vs. lithium-ion

The recycling of lead-acid batteries has long operated within a mature and efficient system. Up to 90–96% of the lead, plastic casing and electrolyte can be recycled and used to manufacture new batteries or for other industrial purposes.

By contrast, recycling lithium-ion batteries is currently technologically more complex and more expensive, and the recovery rate is generally lower (around 70–80%). However, developments are progressing rapidly, and the aim is to create a more cost-effective, sustainable system.

A second life

Fortunately, used lithium-ion batteries do not have to end up at the recycler straight away. An increasingly common solution is second-life use, where batteries removed from industrial machines, such as counterbalance forklifts, are reused in other areas.

Typical examples:

  • industrial energy storage systems (e.g. for solar panels),
  • uninterruptible power supplies (UPS),
  • smaller electric vehicles or mobile devices.

Thanks to their modular design, battery cells can easily be reassembled, replaced or repackaged, so their service life can be significantly extended before they finally go to the recycler.

What should you consider before replacing a battery?

If your company operates counterbalance forklifts and the time has come to replace the batteries, it is worth thinking long term. It is not only the price or performance that matters, but also what we do with the old battery.

Questions worth asking:

  • Is the new battery recyclable and environmentally friendly?
  • Is it modular, repairable and repackageable?
  • Do we know how to store and transport used batteries safely?
  • Do we have a reliable partner to collect and process the batteries?

Closing thoughts – sustainability in the forklift industry

Using lithium-ion batteries in industrial logistics and in counterbalance forklifts offers major advantages, but it can only be truly sustainable if we do not forget about the end of the life cycle. Reducing environmental impact, safe handling, and reuse and recycling are all part of responsible operations.

The technology is developing rapidly, and even more efficient solutions will soon be available – but making a conscious decision is already in our hands today.
