Description
Discover EV31A-AM 12V 120Ah AGM Deep Cycle Battery
Elevate your industrial or recreational equipment with the Discover EV31A-A, a premium 12V AGM (Absorbed Glass Mat) traction battery designed for exceptional reliability and performance. This sealed, maintenance-free Dry Cell VRLA battery from Discover Battery provides 120Ah capacity (20-hour rate) at 1.80 VPC, offering superior runtime, deep discharge resilience, and extended cycle life—surpassing traditional flooded, AGM, and gel options in demanding applications such as aerial work platforms, floor care machines, material handling, utility EVs, golf carts, and work vehicles.
Key Features and Benefits
- Advanced Dry Cell AGM Technology: Incorporates Hydro Polymer electrolytes for organic capillary separation that resists dry-out and thermal runaway, maintaining consistent performance throughout the battery’s life. Enhanced alloys with thick plates and carbon additives improve duty cycle efficiency, charge acceptance, and partial state-of-charge operation.
- Superior Durability: Automated through-the-partition welding enhances intercell consistency, supports higher current loads, and reduces internal resistance. The rugged polypropylene case provides high heat resistance, exceptional vibration tolerance (shock-tested to IEC 61373 and SAE J537 standards), and is nonspillable, no-gassing, and explosion-proof (SAE J1495 certified).
- Extended Runtime and Life: Delivers 550+ cycles at 70% Depth of Discharge (IEC 60254-1) and 350+ cycles at 100% DoD (DIN 43 539), with 80% DoD above 1.9 VPC. Low self-discharge (2-3% per month) and compatibility with AGM/gel semi-traction charge profiles (IUI, IUI Pulse, or IUU) optimize efficiency.
- Extreme Condition Resilience: Operates in discharge temperatures from -40°C to 50°C (-40°F to 122°F), with superior high-temperature life compared to standard AGM and better low-temperature performance than flooded or gel batteries. Perfect for frequent, heavy-duty use in scrubbers, sweepers, and more.
- Safety and Compliance: Maintenance-free with no transport restrictions (IMDG, IATA/ICAO, DOT). Certified to UL, CE, ISO/DIN standards, and produced in ISO 9001/14001 facilities. Top-charge within 6 months of storage to avoid sulfation.
