36V Lithium Forklift Battery
Sisway Battery manufactures 36V lithium batteries for three-wheel electric forklifts, stackers, and pallet trucks. These batteries support single- and multi-shift operations.
Our lineup includes 420Ah, 690–700Ah, and 840Ah capacities. Choose the right option for standard shifts or extended runtime.
Each battery uses LiFePO4 technology and an integrated Battery Management System (BMS). The design supports easy replacement of standard 36V lead-acid battery packs.
These lithium batteries charge faster than lead-acid batteries. They require no watering or equalization. They also maintain stable voltage throughout the discharge cycle.
Consistent power helps maintain reliable lift performance during long shifts. It also reduces routine battery maintenance for industrial operations.
Sisway supports OEM and ODM programs for distributors, forklift manufacturers, and industrial buyers. We can customize capacity, casing, connectors, and BMS communication protocols.

Why Choose a 36V Lithium Forklift Battery
A 36V lithium forklift battery replaces the 18 lead-acid cells found in a conventional 36V pack with LiFePO4 cells managed by an integrated BMS, which monitors voltage, temperature, and charge state across every cell. The result is a flatter, more consistent voltage curve throughout the discharge cycle, so lift performance doesn't taper off late in a shift the way it does with lead-acid.
Fast Charging & Opportunity Charging
Standard 36V lead-acid batteries typically need a full 8-hour charge plus a cooling period before reuse. A 36V lithium forklift battery charges significantly faster and supports opportunity charging — topping up during scheduled breaks without a full discharge cycle or a dedicated battery-swap fleet.
Maintenance-Free Operation
No watering, no equalization charging, and no acid checks. Routine maintenance labor that lead-acid batteries require is eliminated entirely, lowering the total cost of ownership over the life of the battery.
Long Cycle Life
Sisway's 36V lithium forklift batteries are built for a long rated cycle life — well beyond what a comparable lead-acid pack delivers before capacity drops below a usable threshold.
Consistent Power Under Load
Because lithium chemistry doesn't suffer the voltage sag of lead-acid as it discharges, forklifts running on a 36V lithium battery maintain more consistent lift speed and load handling throughout a full shift.
36V Forklift Battery Applications
36V is a common voltage class for lighter and mid-sized material handling equipment, including:
- Three-wheel electric forklifts
- Stackers
- Pallet trucks and pallet jacks
- Warehousing and distribution center operations
- Light manufacturing and logistics facilities
Choosing the Right 36V Capacity for Your Shift Pattern
Sisway's 36V lithium forklift battery range spans 420Ah to 840Ah, with custom capacity and weight configurations also available to match your specific equipment and tray requirements. The right capacity depends primarily on how many hours per day your equipment runs:
- Single-shift operations (up to 8 hours): A 420Ah battery typically covers a full shift with margin for opportunity charging during natural breaks.
- Extended or two-shift operations: The 690–700Ah capacity, combined with opportunity charging between shift changes, keeps equipment running without a dedicated battery swap.
- Continuous or high-utilization use: The 840Ah model paired with a structured opportunity-charging schedule is typically the more cost-effective path versus a lead-acid battery-swap fleet.
36V Lithium vs. Lead-Acid Forklift Batteries
| Factor | 36V Lithium (LiFePO4) | 36V Lead-Acid |
|---|---|---|
| Charging Time | Supports fast & opportunity charging | ~8 hours plus cooling period |
| Maintenance | None — no watering or equalization | Regular watering & equalization required |
| Voltage Under Load | Consistent through full discharge | Drops progressively as it depletes |

Frequently Asked Questions
What forklifts use a 36V battery?
Three-wheel electric forklifts, stackers, and pallet trucks commonly run on 36V systems. Sisway's 420Ah model is compatible with major forklift brands including Toyota and Hyster.
Can I replace my existing 36V lead-acid battery with lithium?
In most cases, yes. Sisway can match custom casing dimensions to your existing battery tray, and our team can confirm connector compatibility based on your forklift model.
What capacity do I need for my shift pattern?
420Ah typically covers a single 8-hour shift, 690–700Ah suits extended or two-shift use, and 840Ah is built for continuous or high-utilization operations. Contact our team for a recommendation matched to your equipment.
Do you offer custom 36V lithium battery configurations?
Yes. Sisway's OEM/ODM service supports custom Ah ratings, BMS communication protocols, casing dimensions, and private-label branding on every order.
Is a 36V lithium forklift battery safe for indoor use?
Yes. LiFePO4 chemistry is inherently stable with low fire risk, and Sisway's integrated BMS adds protection against overcharge, overheating, and short-circuit conditions.
