Forklifts are moving to lithium-ion because it charges faster, lasts longer and needs less maintenance than lead-acid — and the shift is well under way, with lithium-ion at 54.6% of US electric-forklift revenue in 2025. Lithium suits opportunity charging and multi-shift work: top up during breaks instead of swapping a battery, with no watering and no cool-down. The trade-off is a higher up-front price, which pays back fastest on high-hour, multi-shift duty. For single-shift operations, lead-acid can still be the cheaper choice. This guide explains why the shift is happening, where lithium pays off, and what to weigh before you specify it. HONGLI ships its electric forklifts with a lead-acid pack as standard and offers a lithium upgrade.
Lithium vs lead-acid
| Factor | Lithium-ion | Lead-acid |
|---|---|---|
| Charging | Fast; opportunity charging | Slower; full charge + cool-down |
| Maintenance | None (no watering) | Watering, equalising |
| Life | 5–10 years | Shorter |
| Up-front cost | Higher | Lower |
| Best fit | Multi-shift, opportunity charging | Single-shift, budget |
Why the shift is happening
Lithium’s energy density, fast charging and zero maintenance answer the two biggest electric-forklift pain points: charging downtime and battery upkeep. As prices fall and multi-shift demand grows, the share keeps rising — already a majority of US electric-forklift revenue.
Where lithium pays off
and where it does not — High-hour, multi-shift sites recover the premium fastest through uptime and lower upkeep. Single-shift operations with room to charge overnight may still choose lead-acid on price. Match the chemistry to your shift pattern, not the headline.
FAQ
Why are forklifts switching to lithium-ion?
Faster charging, longer life and zero maintenance against lead-acid. It already holds 54.6% of US electric-forklift revenue.
Is lithium always the better choice?
No. It pays back fastest on multi-shift, high-hour duty. Single-shift work may still suit lead-acid on price.
Can I retrofit lithium to an existing truck?
Sometimes — confirm voltage and tray fit. HONGLI offers a lithium upgrade on its electric forklifts.
How long does a lithium pack last?
Typically 5–10 years, depending on use and charging.
