Original buyer tool
Five-year battery decision matrix
JIA CHENG prepared the comparison table as a blank TCO input model for duty, facility, labour, integration and local cost assumptions.
This is an original JIA CHENG procurement worksheet supplied as a blank decision aid. It does not represent a customer case, test report or completed inspection record.
Key takeaways
- Measured truck-level use gives the best input for battery and charger selection.
- Lead-acid planning includes charging, watering, cleaning, ventilation and change arrangements.
- Lithium planning includes BMS, compatibility, charging profile and damaged-battery response.
- Five-year comparison should expose local electricity, labour, finance, downtime and residual assumptions.
Measure duty before comparing chemistry
Toyota energy-consultation guidance uses operating data such as run time, idle time, available charging periods and amp-hour use to study power needs. Gather representative truck-level records across peak and normal days before setting battery quantity or charger capacity. [1] [2]
| Input | Lead-acid model | Lithium model |
|---|---|---|
| Duty | Discharge, charge and change cycle | Run and opportunity-charge cycle |
| Facility | Charging, ventilation and service area | Charging, electrical and fire review |
| Labour | Watering, cleaning and battery handling | Inspection and BMS response |
| Integration | Weight, connector and charger | Weight, connector, BMS and charger |
Verify operational and compatibility claims
Crown describes opportunity charging and BMS monitoring for its integrated lithium systems. Toyota states that lithium compatibility depends on specific battery and truck combinations. Treat these as manufacturer-specific capabilities and obtain written evidence for the exact offered battery, truck and charger. [3] [4]
- Record usable energy, charge rate and temperature conditions from current technical data.
- Confirm battery mass, compartment, restraint, connector and communication.
- Define warranty measurement, service access, diagnostics and replacement support.
Build a transparent five-year cost comparison
JIA CHENG procurement practice: Use buyer-owned inputs for batteries, chargers, electrical work, change equipment, battery room, water and cleaning, labour, energy, maintenance, downtime, finance, warranty and residual value. State utilization hours and sensitivity assumptions so the output remains a planning estimate.
- Keep capital, operating and risk costs in separate worksheet sections.
- Model peak-day battery coverage and charger downtime scenarios.
- Review transport, fire, electrical, recycling and workplace requirements by destination.
Frequently asked questions
Is lithium always cheaper than lead-acid for forklifts?
Cost depends on measured duty, electricity, labour, infrastructure, battery count, compatibility, warranty, service, downtime, finance and the selected comparison period.
Why is opportunity charging important for multi-shift fleets?
Approved charging during idle windows can change battery quantity and workflow. The exact chemistry, BMS, charger and truck combination sets permitted charging behaviour.
Which data should a forklift power study collect?
Collect truck-level run hours, amp-hours, state of charge, idle periods, breaks, shift overlap, temperature, peak demand and charger availability.
