The 24V 12-85-13 battery is a heavy-duty lead-acid power solution designed for Crown 30SP36 forklifts with a 30.68-inch compartment. Delivering ~850Ah capacity, it supports 6–8 hours of runtime under moderate loads. Compatibility hinges on precise terminal alignment and voltage matching. Pro Tip: Always verify BCI group size (GC2) and use Crown-approved chargers to avoid under/overcharging, which degrades lifespan by 30–40%.
How Much Does a Forklift Battery Weigh?
What makes the 24V 12-85-13 battery compatible with Crown 30SP36 forklifts?
Compatibility centers on the 30.68″ length, 24V configuration, and terminal placement matching Crown’s power tray design. Deviations as small as 0.5″ can cause mounting failures or cable strain.

Beyond physical dimensions, the Crown 30SP36 requires a battery with 2,000–3,000 cycle life under industrial loads. The 12-85-13’s 6D BCI group ensures terminal polarity (positive front-right) aligns with forklift connectors. Did you know? Using a mismatched charger—say, 48V on a 24V system—can fry control boards in seconds. For instance, a logistics hub reduced downtime 22% by standardizing all chargers to 24V/40A. Pro Tip: Measure compartment width (9.25″ min.) before purchasing—some aftermarket batteries add insulation layers that cause fit issues.
| Battery Model | Length | Voltage |
|---|---|---|
| 12-85-13 | 30.68″ | 24V |
| 12-100-15 | 33.5″ | 24V |
What are the specifications of the 24V 12-85-13 battery?
This 850Ah battery weighs ~1,150 lbs, needing mechanical lifting. Electrolyte capacity is 34L per cell, with 18-plate design for sustained 335A discharge.

In practical terms, the 12-85-13’s 24.8V nominal voltage drops to ~21V under 80% discharge. Charging requires 28–29V absorption phases—why risk undercharging? A warehouse in Ohio doubled battery lifespan by switching to 3-stage chargers with temperature compensation. Technical specs:
- Terminal Type: DIN/SAE dual-post
- Recharge Time: 8–10 hours (20% DoD)
- Self-Discharge: 3–5% monthly
Pro Tip: Add distilled water only after full charging to prevent acid overflow during gassing.
How does the 24V 12-85-13 compare to lithium-ion alternatives?
Lithium packs offer 60% less weight (~450 lbs) but cost 3x upfront. However, they tolerate 80% DoD vs lead-acid’s 50% limit, effectively doubling usable capacity.
While lithium’s 2,000+ cycles seem appealing, their BMS complexity introduces new failure points. Ever seen a forklift stranded due to a tripped BMS? A food distributor reported 12 BMS-related outages yearly until staff training improved. Key comparisons:
| Feature | 12-85-13 | Lithium |
|---|---|---|
| Cycle Life | 1,500 | 3,000 |
| Charging Time | 8h | 2h |
Pro Tip: For multi-shift operations, lithium’s rapid charging offsets higher initial costs.

FAQs
Only if dimensions match Crown’s 30.68″ limit—overweight batteries strain chassis welds. Consult our Forklift Battery Weight Guide.
Does cold storage affect performance?
Lead-acid loses 40% capacity at -20°C vs lithium’s 15% loss. Use insulation blankets below freezing.
