Choosing the right battery for a forklift is not just about powering the truck. It affects how long the machine runs each day, how often it needs to be serviced, and how safe your workplace is. For years, lead-acid batteries were the standard option. Today, lithium-ion technology is challenging that dominance, offering faster charging and lower maintenance. Deciding which is better depends on how your business operates and what you value most: cost, convenience, or long-term efficiency.
Lead-acid batteries have been around for decades. They’re reliable, widely available, and cheaper to buy upfront. Many warehouses are already set up with the charging infrastructure they require. However, they need frequent upkeep: topping up water levels, checking connections, and cleaning terminals are part of the routine. Charging is also slow. A full cycle can take eight hours, followed by another eight hours to cool before use. For single-shift operations this might not matter, but for continuous work it creates delays.
Lithium-ion batteries bring a different set of advantages. They can be “opportunity charged,” meaning operators can top them up during breaks without harming lifespan. They also hold power consistently until fully discharged, rather than dropping off gradually like lead-acid. They’re virtually maintenance free, which saves time for technicians and operators alike. The downside is cost: lithium-ion batteries are significantly more expensive to purchase. That said, many businesses find the efficiency gains justify the investment within a few years.

Looking at the upfront price alone, lead-acid seems the obvious choice. But the bigger picture tells a different story. Lithium-ion batteries last up to four times longer, so fewer replacements are needed over a forklift’s lifespan. They also use energy more efficiently, cutting electricity costs. For high-intensity operations running multiple shifts, lithium-ion often works out cheaper in the long run. For smaller businesses with lighter use, the savings may not be as significant.
Lead-acid batteries release hydrogen gas when charging, which requires well-ventilated areas to avoid explosions. Acid spills are another concern if batteries are damaged or mishandled. Lithium-ion avoids those risks, though poor-quality packs can overheat or, in rare cases, ignite. The solution is choosing high-quality, certified lithium-ion units and installing the right charging equipment. Either way, safety training for staff is non-negotiable. Batteries are heavy, chemical systems that must be treated with respect.
Sustainability is now part of most procurement decisions. Lead-acid batteries are recyclable, but the process is energy-heavy and involves handling hazardous substances. Lithium-ion batteries are more energy efficient in daily use, but recycling systems are still catching up with demand. On balance, lithium-ion has the edge thanks to reduced energy waste and lower maintenance requirements, though businesses must plan ahead for eventual recycling.
There’s no universal winner. If you run a small warehouse on a single shift and already have lead-acid charging stations, staying with lead-acid may be the most cost-effective option. If your forklifts operate around the clock, lithium-ion can unlock efficiency by cutting downtime and simplifying maintenance. The right decision depends on the scale of operations, budget priorities, and how much you value long-term savings over upfront expenditure.
The industry is steadily moving towards lithium-ion as the preferred option, supported by advances in technology and environmental pressures. That doesn’t mean lead-acid is obsolete. For many businesses it still makes sense, particularly where budgets are tight or utilisation is moderate. Planning ahead now allows businesses to adapt their fleets at the right pace, without being caught off guard as standards evolve.
So, lithium-ion vs lead-acid: which is better? Lead-acid remains affordable and practical for lower-use environments. Lithium-ion delivers speed, consistency, and long-term value for high-demand operations. The key is not choosing what’s popular, but what’s right for your site.
