A 24V 12-85-13 Big Joe PDC 20 XtraPower battery is a specialized lithium-ion pack designed for Big Joe’s PDC 20 electric walkie pallet jacks, providing 24V nominal voltage, 850Ah capacity (5-hour rate), and a 13-cell configuration. This OEM-compatible battery ensures optimal power delivery and lifespan (2,000+ cycles) for heavy material handling. Key features include IP54 protection, integrated BMS for thermal/voltage control, and compatibility with Big Joe’s XtraPower charging systems.
How to Access the Battery on a Toyota Forklift
Why choose a 24V 12-85-13 battery for Big Joe PDC 20?
Compatibility is critical—the 12-85-13 model matches the PDC 20’s voltage and tray dimensions. Its lithium-ion chemistry (NMC or LiFePO4) offers 30% longer runtime than lead-acid. Pro Tip: Always verify your forklift’s voltage (nameplate) and tray size (LxWxH) before purchasing.

Big Joe’s PDC 20 requires precise voltage (24V±10%) and dimensions (typically 25″x19″x12″). Using non-OEM batteries risks mismatched communication protocols—the XtraPower BMS syncs with the forklift’s controller to prevent overloads. For example, a third-party 24V battery without CANbus integration may trigger error codes. Transitionally, while lithium batteries cost 2x upfront, their 8-year lifespan reduces total ownership costs by 40%.

What are the signs your PDC 20 needs a battery replacement?
Performance decline—reduced lift speed, frequent shutdowns, or voltage sag below 20V under load—indicates cell aging. Lithium-ion packs typically lose 20% capacity after 1,500 cycles. Check BMS logs for cell imbalance warnings.
Lead-acid batteries show visible corrosion or electrolyte leaks, but lithium failures are subtler. Use a multimeter: if voltage drops >15% during a 500kg lift, cells are deteriorating. Practically speaking, a 24V 850Ah battery should power a PDC 20 for 6–8 hours—if runtime halves, replacement is due. Real-world example: A warehouse replacing batteries every 3 years saw a 22% productivity drop from unplanned downtime. Pro Tip: Track cycle counts via BMS software—most 12-85-13 cells degrade past 80% capacity at 2,000 cycles.
| Lead-Acid | Lithium-Ion |
|---|---|
| 500–800 cycles | 2,000+ cycles |
| 50% runtime at 400 cycles | 85% runtime at 1,500 cycles |
Can you repair a 24V XtraPower battery instead of replacing it?
Lithium-ion cell replacement is possible but risky without OEM tools. Big Joe’s sealed BMS and welded cells require factory reconditioning. Third-party repairs void warranties and may cause thermal runaway.
Unlike lead-acid, where you can replace individual cells, lithium packs demand uniform internal resistance across all 13 cells. Transitionally, attempting DIY repairs often worsens imbalance—a 0.05V difference between cells reduces capacity by 12%. For example, a warehouse technician swapping one swollen cell saw pack voltage fluctuate between 22V–26V, tripping BMS safeguards.
How do OEM and third-party 24V batteries compare?
OEM batteries guarantee compatibility and warranty (typically 2 years), while third-party options are 25% cheaper but risk BMS mismatches. Key differences lie in cell quality and thermal management.
Big Joe’s XtraPower uses Grade A NMC cells with ±1% capacity tolerance, whereas aftermarket packs often use Grade B (±5%). Transitionally, while a $3,000 third-party battery saves upfront costs, its 1,200-cycle lifespan (vs. 2,000+ cycles for OEM) increases long-term expenses by 18%. Example: A logistics company using off-brand batteries reported 3x more charger faults due to incorrect CC-CV settings. Pro Tip: Always request UN38.3 and UL certifications for third-party batteries.
| OEM | Third-Party |
|---|---|
| $4,200–$5,000 | $2,800–$3,500 |
| Integrated CANbus | Generic BMS |
How to maximize 24V XtraPower battery lifespan?
Avoid deep discharges below 20% SOC—store at 40–60% charge if unused. Use Big Joe’s recommended chargers with 24V/30A output to prevent overvoltage. Calibrate BMS every 500 cycles.
Charging habits matter most: random partial charges (30–80%) stress cells less than full cycles. For instance, a delivery hub adopting 50–80% charging saw cell degradation slow by 33%. Transitionally, temperature control is vital—operating above 113°F (45°C) halves cycle life. Pro Tip: Install battery compartment fans if ambient temps exceed 95°F (35°C).

FAQs
Only PDC 20 and MDC 20—check voltage (24V) and tray dimensions. Using it in 36V systems risks motor burnout.
Can I use a 24V lead-acid charger for XtraPower?
No—lithium requires constant-current/constant-voltage (CC-CV) profiles. Lead-acid chargers overheat lithium cells, triggering BMS shutdowns.
How to recycle a dead 24V forklift battery?
Contact Big Joe or Redway for EPA-certified recycling—lithium packs mustn’t be landfill-disposed due to fire hazards.
