Is a Li-Ion Forklift Battery Worth the Extra Cost?
In the material handling industry, productivity and efficiency are two important keys to success. There are only so many hours in the day, so whenever a company can find a way to do more in less time, they gain a competitive advantage. For some operations, especially food processing, 3PL and other multi-shift applications, lithium-ion forklift batteries provide that extra edge by reducing labor costs and improving productivity.
In this article we’ll answer common questions about lithium-ion (Li-Ion) forklift batteries including:
– How long does it take to charge a lithium-ion forklift battery and
– When are lithium-ion forklift batteries worth the extra cost?
Q: What Applications Benefit Most from Lithium-Ion?
Multi-shift applications such as 3PL **, manufacturing and food processing and any other 24/7 material handling operations benefit most from switching to lithium-ion. For these type of operations, li-ion batteries can pay for themselves within a few years.
Operations where forklifts operate in cold environments can also quickly benefit from switching to lithium-ion. lithium-ion forklift batteries can be fast-charged in cold temperatures (even inside freezers) and maintain their capacity in cold temps better than their lead-acid counterparts.
Q: How much does a lithium-ion forklift battery cost?
The average price for a lithium-ion forklift battery is roughly $17-20k (about 2-2.5x more than a similar lead-acid battery). For that higher upfront price, an operation will save money on:
- Energy bills: lithium-ion batteries are 30% more energy-efficient and charge 8x faster than lead-acid batteries
- Batteries: your lithium-ion battery will last 2-4x longer than a lead acid battery
- Downtime: lithium-ion batteries never need to be swapped out and can be opportunity-charged during operator breaks
- Labor costs: lithium-ion forklift batteries do not require maintenance or watering
- Productivity: enjoy longer run-times and no decline in performance as the battery discharges
- Hazards: li-ion batteries don’t emit harmful fumes or CO2, there’s no risk of acid spills, and you’ll have 70-80 percent fewer batteries to dispose of over time because you won’t be replacing batteries as often.
- Real estate: reclaim the area you’re using as a charging room for additional storage
Q: How long does a lithium-ion battery take to charge?
A: Li-ion batteries can charge throughout the day in 15 or 30 min spurts, or fully charge during a one to two hour continuous session. Compare this to the eight hour charge time plus an additional eight hour cool down time for a lead-acid battery.
Q: How much runtime will I get from a lithium-ion battery?
As with lead-acid batteries, the runtime depends on the application (how much lifting, how much uphill travel). Generally speaking, a lithium-ion battery will last as long as a lead-acid battery – but it charges faster and does not cause a decline in performance as it discharges.
Q: Can a forklift be retro-fitted to use a Lithium-ion battery?
Yes! Conversion is quick and easy. The retro-fit simply requires installing the new battery and adding the charge meter.
Q: What about counterbalance forklifts?
Ballast is included within the lithium-ion battery case so it meets the required minimum battery weight specification.
Even though lithium-ion batteries cost more upfront, they can quickly pay for themselves through reduced operating costs – offering some businesses a long-term competitive advantage.
** A 3PL (third-party logistics) provider offers outsourced logistics services, which encompass anything that involves management of one or more facets of procurement and fulfillment activities. In business, 3PL has a broad meaning that applies to any service contract that involves storing or shipping items. A 3PL service may be a single provider, such as transportation or warehouse storage, or it can be a systemwide bundle of services capable of handling supply chain management.
