Battery technology has changed more significantly than any other aspect of electric pallet jacks for sale over the past decade. Buyers who evaluated electric pallet handling equipment years ago and formed a view about battery performance based on that experience may find that the current options address limitations that were previously a genuine concern.
For operations making a fresh decision, or reviewing their battery approach on an existing fleet, the lead-acid versus lithium-ion choice has direct operational consequences that go beyond the purchase price.
Lead-acid batteries: the established option
Lead-acid is the traditional battery technology for electric pallet jacks for sale in the Australian market. It is a mature, well-understood technology with a broad service base, widely available replacement cells, and a lower acquisition cost than lithium-ion.
The operational constraints of lead-acid are specific:
Full charge cycles are required. Lead-acid batteries suffer from reduced capacity when regularly partially charged rather than fully discharged and recharged. This is called the memory effect in older battery chemistry and capacity stratification in newer designs. The practical implication is that charging windows need to be planned around full discharge-recharge cycles rather than opportunity charging.
Dedicated charging windows. Most lead-acid batteries require a full charge cycle of several hours. In multi-shift operations, this means either battery swap arrangements or scheduled charging windows that align units off the floor.
Ventilation requirements. Lead-acid batteries emit hydrogen gas during charging. Charging areas need adequate ventilation, which is a real infrastructure consideration in enclosed facilities.
Water maintenance. Flooded lead-acid batteries require periodic watering to maintain electrolyte levels. Sealed lead-acid variants reduce this requirement but add cost.
Lithium-ion batteries: the operational upgrade
Lithium-ion electric pallet jacks for sale carry a higher acquisition cost. The operational differences justify that cost premium for a significant proportion of applications.
Opportunity charging is effective. Lithium-ion batteries tolerate partial charge cycles without capacity degradation. This means the machine can be plugged in during any break, a meal break, shift changeover, or brief operational pause, and the available energy is maintained across the shift without a planned full-cycle window.
Faster charge times. Lithium-ion cells charge more rapidly than lead-acid. Even a partial charge during a thirty-minute break meaningfully extends the machine’s available operating range.
No ventilation requirement during charging. Lithium-ion does not produce the hydrogen off-gassing of lead-acid, removing the ventilation infrastructure requirement from the charging area.
