Battery Safety 101: Staying Safe with Batteries in Mobility Equipment

Batteries are at the heart of modern mobility, powering a wide range of equipment from mobility scooters to powerchairs and portable oxygen concentrators. As these technologies evolve, so too does the importance of using batteries safely. Whether you're a user, caregiver, or healthcare provider, understanding how to safely handle, store, charge and dispose of batteries is crucial to protecting both people and property. This guide shares best practices for battery safety and includes a dedicated section on lithium batteries, which pose unique risks.

Why Battery Safety Matters

Battery incidents can cause serious damage, injuries, or even fatalities. Fires linked to battery misuse or failure are increasingly common across New Zealand. From lead-acid to lithium-ion, all battery types require proper handling and maintenance. Good battery safety not only ensures optimal device performance but can also prevent emergencies.

At Allied Medical, we provide a wide variety of battery-powered mobility solutions. These include:

  • Powerchairs and scooters
  • Power assist systems
  • Portable medical equipment

Each of these devices relies on either sealed lead-acid (SLA), nickel-metal hydride (NiMH), or lithium-ion batteries, all of which must be treated with care.

General Battery Safety Best Practices

1. Handling and Inspection

  • Always inspect batteries before use. Look for cracks, leaks, corrosion, or swelling.
  • Avoid handling batteries that appear damaged. Report and isolate them.
  • Use clean, dry hands or gloves when dealing with batteries.

2. Charging Safely

  • Use only manufacturer-approved chargers.
  • Plug directly into a wall socket whenever possible.
  • Never charge near flammable materials.
  • Avoid charging in excessively hot or cold environments.
  • Do not overcharge or leave batteries connected after a full charge.

3. Storage

  • Store batteries in a well-ventilated, dry area away from direct heat or sunlight.
  • Keep away from metal objects that might cause a short circuit.
  • Store different battery types separately.

4. Transport

  • Secure batteries to avoid movement, drops or impacts.
  • Protect terminals from contact with conductive materials.
  • Always carry spare batteries in approved cases or containers.
  • For travel tips, especially when flying with battery-powered mobility devices, check out our blog on How to Travel with a Powerchair.

5. Disposal and Recycling

  • Never dispose of batteries in household rubbish.
  • Take used batteries to certified recycling facilities or return to approved providers.
  • Follow specific disposal instructions for different battery chemistries.

Spotlight on Lithium Battery Safety

Lithium-ion batteries, known for their high energy output and light weight, are found in many of our advanced mobility products:

While efficient, lithium batteries also pose an increased risk if mishandled. A recent fire at the Abilities warehouse in Auckland, caused by improper storage/disposal of lithium batteries, serves as a stark reminder of these risks. Fire and Emergency New Zealand (FENZ) reports dozens of such incidents annually, mostly due to improper charging, storage, or disposal.

Specific Risks with Lithium Batteries

Lithium batteries may become dangerous when:

  • Damaged, dropped, or punctured
  • Exposed to heat or direct sunlight
  • Overcharged or charged with unapproved devices
  • Left unattended while charging
  • Stored improperly or disposed of with general waste

These conditions can lead to thermal runaway, causing fires, explosions, or toxic gas emissions.

Best Practices for Lithium Battery Safety

  • Inspect batteries for damage before use.
  • Use only Allied Medical-approved chargers. Ensure they are Tested and Tagged.
  • Charge in supervised environments. Never charge overnight.
  • Avoid using extension cords or power boards.
  • Store in cool, dry, ventilated spaces.
  • Clearly label and package lithium batteries during transport.
  • Recycle through certified providers. Follow special protocols for damaged units.
