Product Description
HD Series is a maintenance-free deep cycle gel battery with a 15-20 year design life in float service. It offers 30% more life than standard gel batteries and 50% more than regular lead-acid AGM batteries. Using 4BS lead paste technology and high-quality nano silica gel electrolyte, it is the optimal choice for backup and frequent cycle discharge applications in extreme environments, designed specifically for both hot and cold climates.
💎 Long Cycle Life: Designed service life exceeds 15 years through advanced corrosion-resistant grid alloy.
🌡️ Extreme Temperature: Reliable operation from -30ºC to 60ºC; ideal for harsh environments.
🛡️ Safety & Stability: Heat sealing technique used instead of glue to ensure maximum tightness and structural integrity.
⚡ Efficiency: Low self-discharge rate and high-efficiency discharge performance using the latest valve regulation technology.

Frequently Asked Questions
Q1: How long is the delivery time for these batteries?
Usually, it takes about 7 days for stock products, 20 days for half-container orders, and approximately 30 days for 20ft full container products.
Q2: Can the batteries be delivered by sea and air?
Yes, our batteries are certified with MSDS and test reports for safe transport by both sea and air as non-dangerous goods.
Q3: Why does the battery have different capacities at different hour rates?
Capacity is dynamic and depends on discharge current. A lower discharge current (e.g., 20-hr rate) allows the battery to deliver more total Ah than a high current discharge (e.g., 2-hr rate).
Q4: What is the shelf life of a VRLA battery?
VRLA batteries self-discharge less than 3% per month at 25°C. They should be recharged every 6 months if stored at room temperature, or every 3 months in hotter environments.
Q5: Is it recommended to fast charge the battery?
Fast charging is generally not recommended as it can be harmful to the long-term health and service life of the battery.
Q6: How do you handle battery damage or quality issues?
If a production-related issue occurs, we investigate the cause based on usage conditions and photos provided. Confirmed defective units are replaced in the next shipment.
