Lithium or Lead-Acid: Choosing a Battery for Your Electric Forklift

Both chemistries are available on the same 1.5–4.0 t electric platform. The useful question is not which battery is better in general, but which one fits the shift, the charging space and the maintenance routine you actually have.

Start with the shift, not the chemistry

A single short shift, a long gap between shifts and a spare battery bay point one way. Two or three shifts with little downtime, and no room for a battery change, point the other way. Pack size, charging window and aisle layout should be written down before a chemistry is chosen.

Where lithium fits

• Opportunity charging between tasks, without a battery change
• No separate battery room or watering routine
• Packs in 125 Ah, 150 Ah and 202 Ah ratings on a 76.8 V (80 V platform) architecture
• A smart BMS that manages charge and discharge, with a 5-year / 10,000-hour cell warranty
• Suited to food, cold-chain and indoor operations where no exhaust is acceptable

Where lead-acid still works

• Lower initial cost per truck, which matters when the budget sets the fleet size
• A mature, well-understood charging and watering routine
• Battery swapping keeps a truck productive while the pack charges
• Requires a dedicated, ventilated charging area and regular watering discipline

A short selection checklist

1. Measure the real shift: hours, load weight and distance travelled.
2. Confirm the charging window and the power supply available on site.
3. Check the cold-store temperature if the truck works in a freezer.
4. Decide on attachments and mast height before the battery pack is specified.
5. Confirm whether a spare pack or a fast-charge routine is the better fit.

Both chemistries are factory-fitted and configured to the local charging conditions; the right answer usually follows the duty cycle rather than the specification sheet.
