Best Deep-Cycle Battery for Marine/RV 2024

Table of Contents

When talking about batteries in a renewable energy setting, the term usually refers to deep cycle batteries. Deep cycle batteries are designed to cycle, meaning to charge and discharge many times. Brava offers class-leading deep-cycle batteries, including AGM, GEL, and lithium batteries, perfect to be as power storage for RV, van, marine, camper, golf cart and a wide variety of applications.

Benefit of Deep-Cycle Batteries

【Maintenance Free & Safe to Use】 Manufactured with thick AGM separators and advanced valve regulated technology, Brava Deep Cycle AGM Batteries save you from acid leakage and frequent maintenance. No acid leakage, no water refilling, and no harmful hydrogen gas.
【Outstanding Discharge Performance】 Proprietary quinary alloy plates and exclusively treated plate grids enable low internal resistance and high discharge currents of up to 10 times the battery rated capacity. This means that Brava AGM batteries can power home appliances with high current ratings.
【Longer Shelf Life】 Upgrades to lithium seamlessly with the standard BCI group size but a greater energy density, a deeper discharge capability, a higher round-trip efficiency, and a faster charging speed.
【Better Performance at Extreme Temp】 The improved electrolyte formula ensures stable battery capacity and outstanding discharge performance from 5℉ (-15℃) to 122℉ (50℃).
【Power Most Appliances】 Featuring 1100A (5 seconds) max discharge current and consistent, stable discharge, the battery can power up most home appliances, such as a fridge, microwave, CPAP, coffee maker, laptop, and more.

【High Quality and High Reliability】

Uses of Deep Cycle Batteries

We’ve already touched on the fact that familiar car batteries are starter batteries. So what are deep cycle batteries used for? In general, for anything that needs continuous power for longer periods of time.

  • Electric golf carts
  • Electric floor cleaning machines
  • Electric scissor lifts
  • Electric wheelchairs
  • Electric scooters
  • Electric forklifts
  • Recreational Vehicles
  • Trolling motors on boats
  • Navigational devices on a boat (when the main motor is inactive)
  • Renewable Energy systems
