Electric vs. Diesel Forklifts: The Best Fit For Your Operation

Adapted with permission From Clark

It may seem like a small piece of the puzzle, but it’s important to select the right type of forklift for your business. 

Choosing between electric and diesel forklifts can successfully boost your operating costs, safety, and uptime for years to come.  

“When picking the best forklift for your operation, don’t just focus on the specs — buy the outcome,” says Aron Sweeney, VP of Marketing for Burwell Material Handling. “If you want to have a more efficient, successful business down the line, then choosing the right type of truck is crucial.”

Below is a practical guide with tips to help you find the right fuel type, size, and machine for your business.

What’s the Difference Between Electric and Diesel? 

Electric forklifts are available in sit-down and stand-up models. They use rechargeable batteries (lead‑acid or lithium‑ion) for power, and are best for indoor or precision work due to their maneuverability, lower noise levels and zero point‑of‑use emissions.

Some common electric forklift types include counterbalanced, reach trucks, and side loader forklifts. 

Diesel forklifts use internal combustion engines (ICE) and are best for outdoor work, heavy loads, and uneven terrain. Think of situations such as yards, construction sites, outdoor staging, steep grades or rough terrain.

Diesel forklifts are divided into two main categories based on the kind of tires they use and environments they’re designed to operate in: internal combustion (IC) cushion trucks and internal combustion (IC) pneumatic trucks.


Electric vs. Diesel at a Glance

Factor Electric Diesel Best When…
Environment Zero exhaust; quiet; ideal indoors Emits exhaust; loud; excels outdoors Air quality/noise limits vs. outdoor power needs
Power/Torque Responsive, precise control Higher peak torque for grades/heavy loads Precision picks vs. heavy/long runs
Run Time Shift length depends on battery/charging Fast refuel; long continuous shifts Limited breaks for charge vs. long shifts
Maintenance Fewer moving parts; longer service intervals Oil/filters 500-1,000 hrs; more consumables Lower shop time vs. easy fueling
Operating Cost Lower energy/maintenance; battery lifecycle Higher fuel and maintenance costs TCO priority vs. rugged duty priority
CapEx Higher upfront w/ charger(s) + infrastructure Often lower upfront for truck alone Facility ready for chargers vs. fuel storage
Noise ≈60-70 dB typical Higher; varies by model/load Noise‑sensitive vs. outdoor tolerant

 

What Do They Cost?

When it comes to electric vs. diesel forklifts, sticker price varies by capacity, mast height, and other available options. 

“Focus on your long-term operating expenses,” Sweeney says. “Fuel consumption, maintenance needs, and repair costs all play a role in determining the total cost of ownership (TCO).”

When it comes to TCO, you have to take into account factors such as:

  • Price: A new electric forklift can cost between $20K to $45K with an additional $2.5K to $5K for battery/charger infrastructure.
  • Maintenance intervals: Electric models often exceed 1,000 hours between services. Diesel is around 500 to 1,000 hours for oil/filter/belt changes.
  • Energy/fuel: Electricity usually costs less per hour than diesel, but you have to factor in battery replacements.
  • Uptime: Diesel refuels in minutes, while electric models require charging/swaps.

How Do I Choose the Right Type? 

Use this quick assessment before you decide which forklift type is best for you:

  • Map your environment: Consider indoor air rules, noise limits, floor conditions, grades, and weather exposure.
  • Quantify duty cycle: Consider hours per shift, breaks, payloads, grades, attachments, and peak season demands.
  • Model uptime: Plan for charging/refueling, battery swaps, or on‑site fuel storage.
  • TCO: Compare energy/fuel needs, service intervals, parts, tires, and expected battery replacements over three to five years.
  • Pilot before you commit: Run one truck for a week in the toughest lane, and validate productivity and operator feedback.

“It’s important you partner with an equipment dealer that can help guide you through all the criteria you need to weigh when selecting your type of forklift,” Sweeney says.

FAQ: Electric vs. Diesel 

Are electric models always cheaper than diesel?

Not always. Electric models often win when it comes to energy and maintenance indoors, but diesel can win on uptime for long outdoor shifts without charging infrastructure.

 

Can diesel forklifts be used indoors?

This isn’t generally recommended due to emissions and noise. Electric models are the standard for enclosed spaces and food/pharma settings.

 

How long do forklift batteries last?

Lead‑acid battery packs often last three to five years with proper watering/charging; lithium‑ion can last longer with a higher upfront cost.

 

What if our layout changes seasonally?

Electric models still fit indoors; if you need outdoor power and flexibility, a mixed fleet (electric inside, diesel outside) is common.
