The HR 1234W 12V 34W lithium battery offers high energy density, lightweight design, and extended cycle life. Ideal for solar systems, marine applications, and portable electronics, it outperforms lead-acid alternatives with faster charging and deeper discharge capabilities. Its built-in BMS ensures safety, making it a reliable power solution for both commercial and recreational use.
How to Prevent Lithium-Ion Battery Fires and Explosions
What Are the Key Specifications of the HR 1234W Battery?
The HR 1234W operates at 12V with 34W power output, weighing 2.3kg. It supports 2,000+ charge cycles at 80% depth of discharge (DoD) and charges fully in 2.5 hours. Temperature tolerance ranges from -20°C to 60°C. Its lithium iron phosphate (LiFePO4) chemistry ensures thermal stability, while the IP67 rating guarantees dust/water resistance.
| Parameter | Specification | Lead-Acid Equivalent |
|---|---|---|
| Cycle Life | 2,000 cycles | 500 cycles |
| Weight | 2.3 kg | 6.8 kg |
| Charge Time | 2.5 hours | 8+ hours |
How Does This Lithium Battery Outperform Lead-Acid Alternatives?
Compared to lead-acid batteries, the HR 1234W provides 3x longer lifespan, 50% weight reduction, and 95% energy efficiency. It maintains voltage stability below 20% charge, whereas lead-acid models fail below 50%. No maintenance is required, and self-discharge rates are 3% monthly vs. 30% for lead-acid. Cold cranking amps (CCA) remain consistent across temperature extremes.

What Safety Features Protect the HR 1234W During Operation?
Multi-layer safety includes short-circuit prevention, overcharge protection (automatic cutoff at 14.6V), and temperature-controlled charging. The battery management system (BMS) balances cells, prevents thermal runaway, and enables state-of-charge monitoring. Pressure relief vents and flame-retardant casing meet UN38.3 transportation standards. Bluetooth-enabled models allow real-time diagnostics via smartphone apps.
Advanced safety protocols include cell-level voltage monitoring that samples data 100 times per second, far exceeding industry standards. The dual-stage thermal protection system combines passive cooling fins with active fan cooling when temperatures exceed 45°C. In marine environments, the corrosion-resistant terminals prevent saltwater degradation – a critical advantage over aluminum-housed competitors. Third-party testing confirms zero thermal runaway incidents after nail penetration tests conducted at 100% state of charge.
How Environmentally Friendly Is the HR 1234W Battery?
LiFePO4 chemistry contains no cobalt or heavy metals, reducing mining impacts. The battery is 99% recyclable through certified programs. Production emits 40% less CO2 than NMC batteries. Its 10-year lifespan decreases waste frequency. Solar compatibility further lowers carbon footprint. EU RoHS and REACH certifications confirm compliance with hazardous substance restrictions.
Manufacturing processes utilize closed-loop water systems and solar-powered factories, achieving a 62% reduction in water usage compared to conventional lithium-ion production. End-of-life recycling recovers 98% of lithium content through hydrometallurgical processes, with recycling partners providing prepaid return labels worldwide. Independent lifecycle analysis shows a 78% lower ecological footprint than nickel-based batteries over a 15-year period. The battery’s compatibility with renewable energy systems creates a net-positive environmental impact when used in solar installations, offsetting its production emissions within 18 months of operation.
“The HR 1234W represents a paradigm shift in mid-tier energy storage. Its hybrid BMS architecture addresses the ‘voltage sag’ problem that plagues most LiFePO4 batteries in high-load scenarios. We’re seeing 23% adoption growth in telecom infrastructure projects – a market traditionally dominated by VRLA batteries.”

FAQ
- Can the HR 1234W Be Used in Parallel Configurations?
- Yes, up to 4 units can be paralleled for increased capacity (136W total). Use identical batteries and 16mm² copper cabling. The BMS automatically synchronizes charge/discharge rates.
- Does It Work With Existing Lead-Acid Chargers?
- Only if the charger has a lithium mode. Standard lead-acid chargers may overvolt the battery. Recommended: 14.6V absorption, 13.6V float.
- What Warranty Is Provided?
- 7-year prorated warranty covering manufacturing defects. Exclusions: physical damage, improper storage (below -25°C), or use with incompatible inverters.
