When you think of forklifts, horsepower and hydraulics might come to mind – but the battery is the true heart of your electric fleet. Choosing the right battery impacts uptime, performance, maintenance costs, and long-term profitability.
At Thompson & Johnson, we work with dozens of businesses every month to help them understand which forklift battery suits their operations best – whether that’s a busy warehouse with multiple shifts, outdoor yard work, or heavy manufacturing.
In this guide, we break down the major forklift battery types – Lead-Acid, TPPL (Thin Plate Pure Lead), and Lithium-Ion – explore their pros and cons, explain proper use and care, and give you a straightforward way to evaluate what’s best for your needs.
Battery Types Overview:
Electric forklifts today are typically powered by one of three battery technologies:
- Lead-Acid Batteries – Classic industrial deep-cycle flooded battery
- TPPL (Thin Plate Pure Lead) Batteries – Premium lead-based sealed battery with performance upgrades
- Lithium-Ion Batteries – Sealed battery with improved energy efficiency
Let’s walk through each…
- Lead-Acid Batteries – The Industrial Standard
Traditional lead-acid batteries have been used in forklifts for generations. They’re proven, accessible, and familiar to most operators.
Pros:
- Lower upfront cost
- Easy to service and repair
- Reliable performance in steady, predictable cycles
Cons:
- Long charge times – often 8–12 hours
- Regular watering and maintenance required
- Lower cycle life compared to advanced chemistries
- Heat sensitivity reduces lifespan in high-temp environments
Best for: Operations with predictable downtime or long break periods between shifts.
2. TPPL Batteries – Premium Lead-Based Option with Big Benefits
TPPL stands for Thin Plate Pure Lead. This technology takes the classic lead-acid design and upgrades it with thin, pure lead plates and improved internal chemistry – delivering performance closer to lithium without being lithium.
TPPL is growing fast in the forklift world because it bridges the gap between traditional and modern power solutions.
Pros:
- Faster recharge than conventional lead-acid
- Higher usable capacity & longer cycle life
- Minimal maintenance – no watering
- Better tolerance for opportunity charging (partial charges)
- Improved performance in temperature swings
Cons:
- Higher cost than standard lead-acid
- Not as “smart” or fast-charging as lithium
- Susceptible to over-discharging
Why TPPL Matters:
TPPL batteries often make sense for operations that:
- Need better uptime than traditional lead-acid offers
- Want reduced maintenance
- Don’t want the higher upfront investment of lithium
Best for: Warehouse fleets on multi-shift rotation where uptime counts but budgets are measured.
3. Lithium-Ion Batteries – The High-Performance Choice
Lithium-ion batteries are the fastest-growing technology in forklifts today. Powered by advanced chemistry and intelligent battery management systems (BMS), they deliver high efficiency with low maintenance.
Pros:
- Fast charge/recharge (often <2 hours)
- Opportunity charging compatible
- Smart controls monitor health & usage
- Lower operating cost long term
- Consistent power delivery all day
- No watering or gassing
Cons:
- Higher initial cost
- Requires compatible charging infrastructure
- Charging performance may dip in extreme cold
Best for: Multi-shift operations, high utilization fleets, and businesses chasing maximum uptime.

Best Practices – Usage & Care:
The right upkeep elevates performance and extends battery life – no matter the chemistry.
Lead-Acid / TPPL Maintenance
✔️ Routine watering (lead-acid) – keep plates covered
✔️ Cleaning terminals & connectors
✔️ Scheduled equalization charging to balance cells
✔️ Avoid deep discharges whenever possible
Lithium-Ion Maintenance
✔️ Use proper Li-ion chargers only
✔️ Track BMS alerts & diagnostics
✔️ Avoid charging at extremely low temperatures
✔️ Maintain clean terminals and correct seating
How to Choose the Right Battery for Your Operation:
Selecting the right battery isn’t luck – it’s strategy. Consider:
Shift Patterns
- Single shift with long breaks → Lead-acid or TPPL
- Multiple shifts or round-the-clock operations → TPPL or Lithium-ion
Budget & Cost Priorities
- Low upfront cost priority → Lead-acid
- Balance cost with performance → TPPL
- Maximize uptime, efficiency, and total cost of ownership → Lithium-ion
Charging Infrastructure
- Do you have space and schedules for long charges?
- Can chargers be located near break rooms to facilitate opportunity charging?
Maintenance Capabilities
- Can your team handle regular watering and equalization?
- Or do you want hands-off power management?
Real World Scenarios:
Heavy Multi-Shift Warehouse – 24/7
- Best Choice → Lithium-Ion
- Fast charge + opportunity topping = minimal downtime
Busy Distribution Facility – 8-16/7
- Best Choice → TPPL
- More uptime, fewer maintenance demands, solid longevity
Occasional Forklift Use
- Best Choice → Lead-Acid
- Cost-effective and dependable for light workloads
FREQUENTLY ASKED QUESTIONS ABOUT FORKLIFT BATTERIES:
How long does a forklift battery last?
Lead-acid: 1,000–1,500 cycles
TPPL: 1,500–2,000 cycles
Lithium-ion: 2,500–4,000+ cycles
Can you opportunity charge a forklift battery?
Lithium-ion and many TPPL batteries allow opportunity charging. Traditional lead-acid generally does not.
Which forklift battery requires the least maintenance?
Lithium-ion requires the least maintenance.
Are lithium forklift batteries worth the cost?
For multi-shift operations, lithium-ion often delivers the lowest total cost of ownership.
