What Are Specs For 24V 12-85-13 Crown 30SP36 Battery?
The Crown 30SP36 24V battery is a deep-cycle lead-acid battery designed for industrial equipment like forklifts, with a 12-85-13 part number indicating its 85Ah capacity at 24V nominal. It uses thick tubular plates for 1,200+ cycles at 50% DoD and weighs ~170 kg, requiring specific chargers (29V absorption voltage). Its IP56 rating ensures dust/water resistance in warehouses.

What are the core specifications of the Crown 30SP36?
This 24V industrial battery delivers 85Ah capacity (C20 rate) via 36 cells in series. Its flooded lead-acid chemistry supports 1,200+ cycles with 3–5-year lifespan under daily use. Dimensions: 335 x 184 x 505mm. Pro Tip: Use Crown-compatible watering systems to prevent plate sulfation during high-frequency cycling.
The Crown 30SP36 operates between -20°C to 50°C, with self-discharge rates under 3% monthly. Electrolyte density ranges from 1.240–1.300 SG when fully charged. Why does plate thickness matter? Thicker tubular plates (8mm vs. standard 5mm) endure deeper discharges without warping. For example, a warehouse forklift using this battery typically achieves 6–8 hours runtime between charges. Always check specific gravity weekly—deviations over 0.025 indicate charging faults.
How does its cycle life compare to alternatives?
The 30SP36 outperforms standard flooded batteries by 30% in cycle durability but lags behind AGM/LiFePO4 options. Its 1,200 cycles assume 50% DoD—discharging deeper than 80% halves lifespan. Pro Tip: Rotate batteries in multi-pack systems to equalize wear.
| Type | Cycles (50% DoD) | Cost per Cycle |
|---|---|---|
| Crown 30SP36 (FLA) | 1,200 | $0.18 |
| AGM | 600 | $0.32 |
| LiFePO4 | 3,500 | $0.11 |
What charging parameters are critical?
Crown specifies 29V absorption voltage with 4–8A current for 7–10 hours. Bulk charging stops at 80% SOC; the remaining 20% requires reduced current. Pro Tip: Install temperature sensors—charging below 0°C demands voltage compensation (+3mV/°C/cell).
Three-stage charging is mandatory: bulk (28.8V), absorption (29V), float (27V). Overcharging beyond 30V accelerates water loss. Why do some chargers fail prematurely? Non-industrial units lack ripple tolerance—Crown’s EnduroCharge series handles 15% AC ripple vs. consumer-grade 5% limits. For instance, a 24V 30A charger completes 30SP36 recharge in 8 hours when battery is 50% depleted.
Can it replace other 24V forklift batteries?
Yes, if dimensions/terminals match—common alternatives include Trojan T-1275 and Enersys 24PPL. Verify post spacing (18.5mm) and plate count (15 plates per cell). Warning: Mismatched post types (DIN vs. SAE) risk connection arcing.
Battery compartments must handle 170+ kg weight—lighter lithium options like our 36V 250Ah LiFePO4 Forklift Battery reduce mass by 60%. However, retrofitting requires charger/controller updates. For example, replacing three 24V lead-acid packs with two 36V lithium units maintains voltage parity while cutting weight.

FAQs
Check levels weekly—top up with distilled water when plates are exposed. Never fill above the max line—overflow dilutes electrolyte concentration.
Can I use solar charging with this battery?
Yes, but ensure charge controllers have FLA presets (29V absorption). MPPT controllers outperform PWM for partial-state-of-charge operation.
What’s the replacement cost?
$1,200–$1,800 USD depending on distributor. Consider leasing programs for high-use facilities to mitigate upfront costs.
