How Do You Select The Right Battery For An Electric Pallet Jack?
Selecting the right battery for an electric pallet jack hinges on voltage (24V or 36V), capacity (Ah), and chemistry. Lithium LiFePO4 batteries offer 3x cycle life vs. lead-acid, lighter weight (∼70% reduction), and faster charging. Match voltage to motor specs, calculate runtime via Ah/load ratio, and ensure BMS compatibility. Avoid mismatched chargers—LiFePO4 needs CC-CV protocols. Prioritize thermal stability for warehouse safety.
What voltage is optimal for electric pallet jacks?
24V and 36V systems dominate pallet jacks, balancing torque and efficiency. 24V suits lighter loads (≤3,000 lbs), while 36V handles heavy-duty (≤6,000 lbs) with 33% longer runtime. Check motor nameplate ratings—overvoltage risks winding burnout. Pro Tip: Use a multimeter to verify existing battery voltage if specs are missing.
Most warehouse pallet jacks use 24V for balanced performance. For example, a 24V 100Ah LiFePO4 battery delivers 2.4kWh, powering 6–8 hours of medium-duty lifting. Technically, voltage directly impacts motor RPM—36V systems spin 50% faster than 24V, but require heavier gauge wiring. Transitionally, higher voltage doesn’t always mean better—consider forklift weight and aisle width. Did you know undersized conductors cause voltage drop, reducing efficiency? Always cross-reference motor amp draw with battery discharge curves.
How to calculate required battery capacity?
Runtime = (Ah × Voltage) / (Load Watts). A 200Ah 24V battery (4.8kWh) running a 1,200W motor lasts ∼4 hours. Factor in 80% depth of discharge (DoD) for lead-acid, 90% for LiFePO4. Pro Tip: Add 20% buffer capacity for peak loads.
Imagine a pallet jack moving 40 pallets/day: each lift consumes ∼5Ah at 24V. Daily usage = 40 × 5Ah = 200Ah. A 210Ah LiFePO4 battery covers this with 95% DoD. Comparatively, lead-acid would need 250Ah for the same duty. Transitionally, warehouse temperature matters—LiFePO4 retains 95% capacity at -20°C vs. lead-acid’s 50%. But how do you account for aging? Battery capacity degrades ∼3%/year for lithium vs. 20% for lead-acid—factor this into replacement cycles.

LiFePO4 vs. lead-acid: Which is better?
LiFePO4 outperforms lead-acid in weight (24V 100Ah = 28 lbs vs. 65 lbs), charge speed (2h vs. 8h), and lifespan (2,000 vs. 500 cycles). Initial cost is 2x higher, but 5-year TCO is 40% lower. Pro Tip: Use lithium if pallet jacks operate in multi-shift environments.
Take a cold storage warehouse: LiFePO4 operates at -30°C without capacity loss, while lead-acid fails below -10°C. Mechanically, lithium’s solid-state construction resists vibration damage—critical for dock ramps. Transitionally, what about recharge memory? Lead-acid suffers sulfation if not fully charged, unlike lithium. A real-world example: Amazon warehouses saved $18k/year per jack by switching to lithium, citing 30% productivity gains from elimination of battery swaps.
| Factor | LiFePO4 | Lead-Acid |
|---|---|---|
| Cycle Life | 2,000+ | 500 |
| Energy Density | 140 Wh/kg | 30 Wh/kg |
Redway Battery Expert Insight
FAQs
Yes, if voltage matches and charger is updated. Lead-acid chargers overcharge lithium—use a compatible CC-CV charger. Redway kits include voltage adapters for 90% of models.
How often should I check battery connections?
Monthly for lithium (vibration checks), weekly for lead-acid (corrosion cleaning). Loose terminals cause arcing—a fire hazard in dusty warehouses.
Do lithium batteries require cooling systems?
Rarely—LiFePO4’s exothermic rate is 1/3 of NMC. Built-in thermal sensors throttle current if temps exceed 60°C. Only needed in foundries >45°C ambient.
