How to Choose the Right Forklift Battery

Nearly two-thirds of all forklifts sold in the U.S. are electric, and 7-10% use a lithium-ion battery. That may not seem like much, but five or six years ago, that percentage was zero.

Experts speculate we're in a big transition period away from lead-acid batteries towards lithium-ion. A recent article from Forklift Action notes:

The benefits of lithium vs. lead-acid batteries have been tested and proven by major companies across all industries ( logistics and 3PL, retail, manufacturing, paper and packaging, metals, lumber, food and beverage, cold storage, medical supplies distribution, etc. Industry experts are speculating about the growth rate… but all agree that the adoption of lithium will continue to accelerate, similar to what we see in the passenger EV market (enabled by similar lithium technology). By 2028, the lithium segment may constitute 48% of all new forklift batteries.

Lead-Acid Forklift Batteries

Let’s start with the standard forklift battery everyone knows: lead-acid. You may have also heard them called flooded lead-acid or wet cell batteries.

If you buy an electric forklift, it will come with a lead-acid battery by default. This type of forklift battery costs significantly less than lithium-ion. But the lower purchase price comes with long-term expenses: weekly maintenance and (for multi-shift operations) a dedicated space for battery charging.

Approximately once a week, lead-acid forklift batteries must be cleaned and watered. This requires a special watering system, safety equipment and properly trained personnel. 

Lead-Acid Forklift Battery Pros:

  • The cheapest option
  • Easy to find service providers when needed

Lead-Acid Forklift Battery Cons:

  • Requires 8 hours to charge plus 8 hours to cool down
  • Power declines as the battery discharges
  • Weekly maintenance (cleaning and watering) required
  • Need space to charge and store extra batteries
  • Capacity decreases up to 35% in cold environments

Lithium-Ion Forklift Batteries

Recently, a major equipment manufacturer discovered they could save $1 million+ per year by switching to lithium-ion. Wondering if your business could uncover massive cost savings like this? Try this simple experiment: 

  • Ask forklift operators to track how much time they spend charging, changing and maintaining forklift batteries every week. Multiply the total time by the hourly cost of labor.

  • Next, add up how much you’ve spent on batteries over the past 10 years. Lithium-ion batteries last  5-7 years (on average). So even though they cost more upfront, you won't buy them as often. 

Add up your labor and battery costs and compare to what you would have spent on lithium-ion batteries (feel free to contact us for pricing). You may find those “cheap” lead-acid batteries cost a lot more in the long run.

You don't need to add in labor costs for lithium-ion forklift batteries because once they get installed in the truck, that's pretty much it. Lithium-ion batteries are virtually maintenance-free. 

Lithium-Ion Forklift Battery Pros:

Lithium-ion batteries can be opportunity charged during breaks without harming the battery. Also, lithium-ion batteries recharge three times faster than lead-acid batteries. Bonus: you don't have to wait for a lithium-ion battery to cool down.

Other benefits include:

  • 30-50% less energy required to charge the battery
  • Consistent power even as the battery discharges
  •  5-7 year lifespan (2-3x longer than lead-acid batteries)
  • Virtually maintenance free (no watering)
  • Zero exhaust

Lithium-Ion Forklift Battery Cons:

  • 3-4x higher purchase price

Lithium-Ion Forklift Battery ROI

Generally speaking, a lithium-ion forklift battery will pay for itself within 3-5 years. A multi-shift operation will recoup costs much faster through: 

  • Reclaimed space
  • Reduced equipment downtime (no battery swapping)
  • Improved employee productivity (no maintenance or battery swapping)
  • Lower energy bills
  • 2-3x longer battery lifespan

EP Equipment | Forklift Battery: Lithium-Ion vs. Lead-Acid

Electric power is becoming increasingly vital in industry, especially in the logistics and material handling sector. With the growing concern for the environment and operational efficiency, choosing the right forklift battery is crucial. In this article, we’ll explore the different types of forklift batteries, their life expectancies, comparison between lithium-ion and lead-acid batteries, and how to choose the right battery for your needs.

Types of Forklift Batteries

1. Lithium-Ion Batteries

Lithium-ion batteries are revolutionizing the material handling industry due to their various advantages:

Longer Life Expectancy

Lithium-ion batteries possess a much longer life cycle compared to lead-acid batteries. With over 3000 cycles, they offer a significantly longer service life, resulting in fewer replacements and reducing operating costs in the long run.

Opportunity Loading

Unlike lead-acid batteries that require full charge cycles, lithium-ion batteries allow for opportunistic charging. They can be recharged quickly during short breaks, such as lunch breaks, reducing downtime and increasing operational efficiency.

Reduced Weight

Lithium-ion batteries are notably lighter compared to lead-acid batteries. Not only does this make it easier to operate the forklifts, but it also allows for more ergonomic and efficient equipment design.

Superior Efficiency

With an efficiency of around 95%, lithium-ion batteries convert a significantly higher amount of stored energy into usable energy compared to lead-acid batteries. This translates into less energy waste and greater operational autonomy.
