In today’s world, lithium-ion batteries are all around us. They are on our laptops, our watches, our phones, and even our toothbrushes. Lithium-ion batteries can also be found in today’s warehouses and distribution centers. So why are companies and products switching to lithium-ion batteries? In today’s blog, we will discuss the difference between lead-acid and lithium-ion batteries and why warehouse managers are making the switch to lithium-ion batteries.
To begin we must look at the advantages and disadvantages of lead-acid batteries. Keep in mind lead-acid batteries have been in use for over 100 years and are still the most widely used battery in today’s forklift world.
Very cost-efficient.
Reliable.
Easy to recycle.
Heavy enough to act as a counterbalance for the forklift.
Enough energy for two shifts.
Long charging times.
Spare batteries for multi-shift operations.
Slower current draw at low charge levels which reduces forklift performance.
Loss of time.
Requires ventilated charging stations because they release harmful gasses while charging.
Risks of exposure to corrosive acid.
Moderately energy efficient.
Maintenance required.
Limited life cycle.
Next, let us look at lithium-ions advantages and disadvantages.
Enough energy for three shifts.
Shorter charging times.
No more battery exchanges.
No more battery bays are required.
No more maintenance or handling as lithium-ion cells do not require a top-off or any other maintenance procedures.
Higher power density.
Higher energy density.
High energy efficiency.
Longer lasting cycles.
Environmentally friendly.
A variety of types available, several types of lithium-ion cells are available.
Cost is typically more expensive than lead-acid.
Lithium-ion batteries are still considered a developing technology and are constantly changing (This may be an advantage as better solutions will be available in the future as technology changes).
Lead-acid is still the most widely used battery and forklifts are made for that design. Many forklifts must be modified to fit the new lithium-ion battery.
As you can see there are many advantages of using a lithium-ion battery. From phones to forklifts, the pros are increasingly outweighing the cons. Due to this advantage, the amount of development will only increase with time. It is important to note the disadvantages of lithium-ion, as with everything, the pros must be weighed against the cons.
In conclusion, lead-acid versus lithium-ion technology could be summarized as.
Long charging times.
Spare batteries for multi-shift apps.
Higher Investment.
Risk in handling heavy batteries.
Loss of time.
Need for special battery bays.
Need for maintenance.
Medium energy efficiency.
Limited life cycle. Environmental issues with acid and lead.
Shorter charging times.
No more extra batteries.
No charging rooms.
No ventilation systems.
No more changing batteries.
No maintenance.
Enough energy for 3 shifts.
More energy efficient.
Longer life cycles.
Environmentally friendly.
It is safe to say lithium-ion batteries are the future of the forklift world. The advantages including increased productivity and fewer maintenance requirements have warehouse managers on watch. Now could be the best time to begin considering if lithium-ion is right for your operation. Consider bringing a Fallsway expert consultant to your facility to see if lithium-ion is the correct choice.
