Battery choice determines more about an industrial vehicle's ownership experience than almost any other spec—how it charges, how much it weighs, how long it lives, and whether it survives multi-shift duty.
Lead-acid: the incumbent
Flooded lead-acid batteries dominate legacy industrial vehicles for one reason: low upfront cost. The tradeoffs are real, though. They demand watering and equalization maintenance, require dedicated ventilated charging areas, suffer from long charge times, and degrade quickly if opportunity-charged or deeply discharged. Effective lifespan often runs 3–5 years with disciplined care—less without it.
Lithium (LiFePO4): the modern default
Lithium iron phosphate packs cost more upfront and win nearly everything after that:
- Opportunity charging: plug in during breaks without damaging the pack—the killer feature for multi-shift fleets.
- Zero maintenance: no watering, no equalization, no acid handling or dedicated ventilation.
- Cycle life: typically several times lead-acid's usable cycles, commonly translating to 8–10 year service lives.
- Consistent power: no voltage sag as charge depletes—the vehicle performs the same at 20% as at 100%.
- Weight and efficiency: lighter packs mean less energy moving battery instead of payload.
The deciding questions
- How many shifts? Single-shift with overnight charging keeps lead-acid viable. Two or more shifts strongly favor lithium or swappable packs.
- Who maintains batteries today? If the honest answer is “nobody, consistently,” lead-acid life will disappoint and lithium's zero-maintenance wins by default.
- What's the 8-year math? Price one lithium pack against two-to-three lead-acid replacements plus maintenance labor and charging-room overhead. Lithium usually wins the total.
Modularity is the multiplier: vehicles with swappable, standardized battery modules let you refresh energy storage without replacing the vehicle—core to how TexTrack designs its platform. Request a quote with the battery strategy that fits your shifts.
