How Does the LiTime 460Ah Battery Compare to Traditional Lead-Acid Batteries?
The LiTime 460Ah battery outperforms lead-acid batteries with 4x faster charging, 50% weight reduction, and 10x longer lifespan. Unlike lead-acid models, it maintains 100% usable capacity, operates in -20°C to 60°C temperatures, and requires no watering or equalization charging. Its built-in Battery Management System (BMS) prevents overcharge/over-discharge, ensuring safer operation.
What Are the Key Specifications of the LiTime 460Ah Battery?
Key specs include 12V nominal voltage, 460Ah capacity (5.5kWh energy), 5,000+ cycles at 80% Depth of Discharge (DoD), and 100A continuous discharge current. It weighs 92 lbs (vs 130+ lbs for comparable lead-acid), features IP65 waterproof casing, and supports parallel/series connections for up to 48V systems. Operating temperature range: -4°F to 140°F (-20°C to 60°C).
| Specification | LiTime 460Ah | Lead-Acid Equivalent |
|---|---|---|
| Cycle Life | 5,000+ | 500-1,200 |
| Weight | 92 lbs | 130-150 lbs |
| Charging Efficiency | 99% | 70-85% |
Which Applications Benefit Most from the LiTime 460Ah Battery?
Prime applications include off-grid solar storage (3-5 days backup), marine trolling motors, RV house banks, and telecom towers. Case studies show 72-hour runtime for 1,000W loads, 8-hour trolling motor operation, and 30% space savings in RV installations. Its vibration resistance makes it ideal for mobile use, while non-toxic chemistry allows safe indoor installation.
How to Properly Install and Maintain the LiTime 460Ah Battery?
Installation requires a dry, ventilated area with proper 12V cabling (4 AWG minimum). Use compatible lithium-specific chargers (14.4V absorption, 13.6V float). Maintenance involves quarterly terminal cleaning, annual capacity testing, and avoiding full discharges below 10.5V. The BMS auto-balances cells, but manual balancing every 500 cycles optimizes performance. Storage at 50% charge in cool environments prevents capacity loss.
What Safety Features Protect the LiTime 460Ah Battery?
Multi-layer protection includes short-circuit cutoff (response time < 200μs), over-temperature shutdown (68°C), and cell-level voltage monitoring. The UL-certified flame-retardant casing prevents thermal runaway. Unlike lead-acid, it produces no explosive hydrogen gas. Pressure relief valves activate at 35 psi to contain internal faults.
Advanced safety mechanisms extend to individual cell monitoring, with the BMS tracking temperature differentials across all 4 cells. If any cell exceeds 65°C during charging, the system automatically reduces current flow. The battery’s crash-resistant design meets UN38.3 transportation standards, ensuring stability during vehicular motion. For marine applications, the IP65 rating provides protection against saltwater corrosion and moisture ingress.
| Safety Feature | Activation Threshold | Response Action |
|---|---|---|
| Overvoltage | 14.6V | Disconnect charging circuit |
| Undervoltage | 10.0V | Cutoff discharge |
| Overcurrent | 150A (5s) | Activate fuse |
Does the LiTime 460Ah Battery Include a Warranty?
LiTime offers a 5-year prorated warranty covering manufacturing defects. The warranty requires proper installation documentation and excludes physical damage or misuse. Capacity retention guarantees: 100% in Year 1, 85% in Year 3, 70% in Year 5. Extended 7-year warranties are available through authorized distributors.
How Does Cold Weather Affect the LiTime 460Ah Battery?
While operational down to -20°C, charging below 0°C requires reduced current (≤0.2C). The self-heating version (sold separately) maintains full charging capability at -30°C. Real-world tests show 92% capacity retention at -10°C vs 40% for lead-acid. Insulated battery boxes improve winter performance by reducing thermal stress.
In sub-zero environments, the battery’s internal resistance increases slightly, causing a 5-8% reduction in peak discharge capacity. However, this performance dip is temporary and recovers when temperatures rise above freezing. For Arctic applications, the optional heating system consumes 3-5% of battery capacity daily but enables reliable operation at -40°C. Users should note that cold weather charging requires compatible chargers with temperature compensation – standard lithium chargers may not activate below 0°C without heater support.

FAQs
- Can I Use My Existing Lead-Acid Charger?
- No – lead-acid chargers may overvolt lithium batteries. Use only LiFePO4-compatible chargers with voltage settings matching LiTime’s requirements (14.4V absorption, 13.6V float).
- How Many Batteries for a 24V System?
- Connect two 12V LiTime 460Ah batteries in series for 24V 460Ah (11kWh). Maximum four strings in parallel for 24V 1,840Ah (44kWh).
- Is Ventilation Required?
- While lithium batteries don’t emit gases during normal operation, provide ≥2 inches clearance around the battery for heat dissipation. Install in non-airtight enclosures.
