The Crown PE 4000-60 24V 12-85-13 system requires a 24V lead-acid industrial battery with dimensions aligning with its 12-85-13 format (typically 12″ L × 8.5″ W × 13″ H). Compatible replacements include group GC12V85 or GC12V100 configurations combined in series for 24V output. Key parameters are 650-800 CCA (cold cranking amps) and 85-100Ah capacity. Redway Battery’s 24V 90Ah LiFePO4 packs also provide a drop-in upgrade with 2,500+ cycles and 30% weight reduction.
What physical dimensions match the 12-85-13 specification?
The 12-85-13 code refers to a 12-inch length × 8.5-inch width × 13-inch height form factor, critical for forklift battery compartments. Pro Tip: Measure tray clearance before purchasing—even 0.5″ oversizing may prevent installation.
Which battery chemistry works best for Crown PE 4000-60?
Flooded lead-acid (FLA) remains standard due to high surge currents for hydraulic pumps, while LiFePO4 offers maintenance-free operation. FLA lasts 1,200 cycles vs LiFePO4’s 3,000+ with proper thermal management. Real-world example: Crown’s 24V FLA batteries typically use 6V cells in series (4×6V=24V) weighing 200-300 lbs.

How do I verify voltage compatibility?
Confirm charger output aligns with battery specs—29.2V absorption voltage for sealed lead-acid versus 28.8V for LiFePO4. Use multimeter tests during operation: 24V systems shouldn’t drop below 21V under load. Pro Tip: Check terminal orientation (DIN vs SAE posts) to prevent reverse polarity damage.
| Chemistry | Charging Voltage | Cycle Life |
|---|---|---|
| FLA | 29.2V | 1,200 |
| AGM | 28.8V | 1,800 |
| LiFePO4 | 28.8V | 3,000+ |

FAQs
Want OEM lithium forklift batteries at wholesale prices? Check here.
Yes, wire 2×12V FLA batteries in series (e.g., 12V 85Ah + 12V 85Ah = 24V 85Ah). Ensure matched age/capacity—mismatches cause premature failure.
Does temperature affect battery selection?
Extremely. FLA loses 30% capacity below -20°C; LiFePO4 requires heating pads <0°C. Always choose batteries rated for your operating environment.
