What Are Specs For 36V 18-125-17 Crown RR5220 45 Battery?

The Crown RR5220 45 battery (36V 18-125-17) is a traction battery designed for Crown electric forklifts. Based on available data for similar Crown industrial batteries:

What voltage/capacity range do Crown 36V forklift batteries use?

Crown’s 36V industrial batteries typically deliver 500–1250Ah capacity. The “18-125-17” in the model likely denotes cell configuration (18 cells) and capacity (125Ah per cell). Pro Tip: Verify BCI group codes with Crown dealers for precise replacements.

Industrial traction batteries like the RR5220 series operate at 36V nominal voltage with high-cycle lead-acid cells. While lithium alternatives exist, Crown’s legacy models often use flooded or AGM lead-acid chemistry. For example, a 36V 1250Ah battery could power a 3-ton forklift for 6–8 hours. Always check plate thickness (ideally >4mm) when evaluating cycle life expectations.

⚠️ Critical: Never mix old/new lead-acid cells in traction packs—uneven sulfation causes premature failure.

How does capacity affect runtime?

Higher Ah ratings extend operating time proportionally. However, larger capacities require bigger footprints—verify compartment dimensions before upgrading.

In Crown’s nomenclature, the “125” in 18-125-17 might indicate 125Ah per cell. For a 36V system with 18 cells (2V each), this suggests 2,250Ah total capacity (18×125). Compare this to the 900Ah and 1250Ah models in Crown’s catalog. Runtime scales with Ah: A 1.5kW forklift motor would draw ~42A at 36V, giving ~53 hours runtime theoretically. But why do real-world applications yield less? Battery efficiency losses (20–30%) and depth-of-discharge limits (50% for lead-acid) cut usable capacity.

9PzS900 900Ah 1100×550×650mm

Battery Expert Insight

Crown’s RR5220 series uses robust lead-acid cells optimized for daily deep cycling in material handling. While newer lithium-ion models offer 3× faster charging, traditional flooded designs still dominate heavy-industrial applications due to lower upfront costs. Always monitor specific gravity (1.265–1.299) during maintenance to maximize service life.

FAQs

Can I replace this with a lithium battery?

Yes, but verify compartment space and charger compatibility. A 36V 250Ah LiFePO4 battery reduces weight by 60% while matching lead-acid performance.

How often should I water the cells?

Check monthly—maintain electrolyte ¼” above plates. Use distilled water only to prevent mineral buildup.
