Lithium-ion or lead-acid: which forklift battery suits your company?

An electric forklift stands or falls with its battery. Not the engine, not the cab, and not the lifting capacity. The battery is key. Because that determines how many hours a day you can work, how quickly you get back to work, how often you need to call a technician, and how much a unit costs you in total over its lifetime.

Today, every company faces the same choice: choose the trusted lead-acid battery or the newer lithium-ion technology? The answer depends on how intensively you work, what sector you operate in, and what you expect in the long term.

The short version: lead-acid vs. lithium-ion at a glance

🔋 Purchase price: lead-acid lower, lithium-ion higher (approx. 25% more)

🔋 Lifespan in cycles: lead-acid 1,000-1,500, lithium-ion 3,000+

🔋 Lifespan in years: lead-acid 5 years (single shift), lithium-ion 10+ years (single shift)

🔋 Charging time: lead-acid 8-12 hours + cooling period, lithium-ion 1-2 hours

🔋 Opportunity charging: not recommended for lead-acid, highly recommended for lithium-ion

🔋 Maintenance: lead-acid requires regular water topping-up, lithium-ion is maintenance-free

🔋 Separate charging room needed: yes for lead-acid (hydrogen gas), no for lithium-ion

🔋 Energy efficiency: lead-acid standard, lithium-ion up to 20% higher

🔋 Suitable for multiple shifts: lead-acid limited, lithium-ion ideal

🔋 Safety (acids): lead-acid risk of acid leaks, lithium-ion no liquid acids

For those with little time: lithium-ion is more expensive to buy, but much cheaper and more convenient over its lifespan. Lead-acid remains interesting for companies with limited or predictable use.

How does a lead-acid battery work?

Lead-acid batteries generate electrical energy through a chemical process between lead plates and sulfuric acid. It is a proven technology that has been the standard in electric forklifts for decades. With proper maintenance, such a battery completes an average of around 1,250 charging cycles, which roughly corresponds to 5 years in a single-shift operation.

Advantages of lead-acid

✅ Lower purchase price than lithium-ion
✅ Widespread availability and proven recycling
✅ Familiar technology, trusted by every technician
✅ Suitable for lighter and predictable usage

Disadvantages of lead-acid

❌ Long charging time: 8 to 12 hours charging, plus cooling period
❌ Reduced performance when the battery is nearly empty
❌ Regular maintenance: topping up demineralized water, keeping clean
❌ Separate charging room required due to hydrogen gas during charging
❌ Not suitable for opportunity charging (intermittent charging)
❌ Sensitive to deep discharge: can cause permanent damage

When is lead-acid still interesting?

• Companies with a single-shift operation and clear overnight charging windows

• Situations where the initial investment is decisive

• Companies that have a low usage intensity and no 24/7 production

How does lithium-ion technology work?

Lithium-ion batteries work via a chemical process where lithium ions move between the anode and cathode. For industrial applications like forklifts, LFP (Lithium Iron Phosphate or LiFePO4) is mainly used. This variant is known for its excellent thermal stability, long lifespan, and high safety.

Unlike lead-acid, a lithium-ion battery is completely sealed and maintenance-free. No water top-ups, no separate charging room, no risk of acid leaks.

Advantages of lithium-ion

✅ Fast charging time: 1 to 2 hours for a full charge
✅ Opportunity charging: charging during breaks is ideal
✅ Maintenance-free: no water top-ups, no scheduled service
✅ Constant performance until nearly fully discharged
✅ Compact and safe: no separate charging room required
✅ Longer lifespan: 3,000 cycles or more, often 10+ years
✅ Higher energy efficiency: up to 20% savings compared to lead-acid
✅ No liquid acids: no risk of leaks

Points of attention

⚠️ Higher purchase price than lead-acid (approx. 25% more)
⚠️ More sensitive to extreme temperatures: requires temperature sensors and good cooling
⚠️ Careful handling: damage from drops or impacts can harm the internal structure
⚠️ Recycling: technology is evolving rapidly but is more complex than lead-acid

LFP: the industry standard Hangcha builds on

Not all lithium-ion batteries are created equal. For forklifts and heavy industrial use, LFP (Lithium Iron Phosphate) is used almost exclusively. Why?

✅ Safety first: LFP has excellent thermal stability and is much less prone to thermal runaway than other lithium chemistries like NMC
✅ Long cycle life: LFP batteries often achieve 3,000 to 5,000 cycles
✅ More stable at high temperatures
✅ No cobalt and nickel: more sustainable and environmentally friendly

The lithium-ion batteries in Hangcha forklifts come from CATL, the global market leader in lithium-ion technology for industrial applications. CATL is the global benchmark for LFP technology, supplying battery cells to both the automotive sector and heavy industry.

Besides the battery itself, Hangcha lithium electric forklifts are equipped with:

✅ An integrated Battery Management System (BMS) that continuously monitors the battery
✅ CAN bus system (Controller Area Network) for real-time monitoring of performance and status
✅ MOSFET system for efficient power regulation and longer battery life
✅ Regenerative braking function that recovers energy during braking
✅ 50% more operating space than a classic electric forklift

The real comparison: Total Cost of Ownership

The purchase price is only a small part of the story. Looking further often reveals a different picture.

What determines total costs over 5 years?

Purchase price: lithium-ion is roughly 25% higher
Energy cost: lithium-ion is up to 20% more efficient due to regenerative braking and lower charging losses
Maintenance: lead-acid requires regular water top-ups, checks, and possible cell replacements. Lithium-ion is maintenance-free
Downtime: lead-acid requires 8 hours of charging plus a cooling period. Lithium can be charged intermittently
Infrastructure: lead-acid requires a separate, ventilated charging room. Lithium does not
Lifespan: lithium-ion lasts 2 to 3 times longer
Residual value: lithium-ion holds better residual value due to its longer lifespan and growing demand

Concrete example

A company operating two shifts typically needs two batteries per forklift with lead-acid (one in use, one charging), plus time for battery swaps. With lithium-ion, one battery charged during breaks is sufficient.

That difference isn't just in the purchase price of the battery. It lies in:

• No second battery required

• No time lost on battery swaps

• No separate charging room

• Fewer staff involved in battery management

In that scenario, lithium-ion often pays for itself in 2 to 4 years, depending on your operational intensity.

A persistent myth around lithium-ion is that the batteries are "dangerous." The reality is more nuanced.

Myth: lithium-ion catches fire faster than lead-acid
Fact: LFP batteries, the type used in forklifts, have excellent thermal stability. They are much safer than other lithium chemistries (like NMC found in laptops and smartphones).

Myth: lead-acid is safer because it is older
Fact: lead-acid batteries emit hydrogen gas during charging. That's why a separate, ventilated charging room is required. With lithium-ion, that risk doesn't exist.

Myth: lithium-ion can leak acid
Fact: lithium-ion batteries are fully sealed and contain no liquid acids. Lead-acid does.

Which sector chooses what?

🔋 Logistics and distribution → Lithium-ion, as multiple shifts and high availability are often required

🔋 E-commerce / fulfillment → Lithium-ion, as 24/7 demand and opportunity charging are crucial

🔋 Food industry → Lithium-ion, to maintain hygiene (no acid fumes) and avoid separate charging rooms

🔋 Cold storage → Lithium-ion, performs better at low temperatures with a proper BMS

🔋 Manufacturing (continuous) → Lithium-ion, for non-stop operation without battery swaps

🔋 SME with 1-shift operation → Lead-acid may suffice, given lower investment and sufficient capacity for one shift

🔋 Construction / job sites → Diesel or lithium-ion, depending on location and usage intensity

Can I convert my existing lead-acid forklift to lithium?

A question we get often. The short answer: sometimes, but not always wise.

Theoretically, a lead-acid battery can be replaced by a lithium-ion variant with an adapted charger. But in practice, you run into several issues:

• The truck's BMS is not configured for lithium voltage curves

• The charger is not compatible

• The forklift warranty may be voided

• The cost is often not much lower than buying a new lithium forklift

For those genuinely wanting to switch, it is usually more interesting to buy a new lithium e-truck than to convert. Service, warranty, and performance are then optimal.
