Despite these advantages, there are some
challenges to consider when it comes to
implementing lithium-ion batteries:
BATTERY WEIGHT: The lighter weight of a
lithium-ion battery can be a benefit, but it is
important to select batteries that have been
supplemented with additional counterweight to
ensure the forklift can be operated as intended.
UPFRONT COST: While their initial cost
may be offset by their longer life and reduced
maintenance, lithium-ion batteries may come
with a higher price tag than lead-acid batteries.
INFRASTRUCTURE AND PROCESS
REQUIREMENTS: Applications and facilities
configured for lead-acid battery use will require
changes to charging processes and locations.
Additionally, forklift operators also need to
be properly trained to understand how the
technology is different from lead-acid batteries
and how they may need to modify their behaviors
to yield longer runtime and extended battery life.
RECYCLING CAPABILITIES: Unlike leadacid batteries, the recycling process for
lithium-ion batteries is complex. There are
a number of options that continue to be
researched and developed.
