Mastervolt batteries: The right choice for power storage

Mastervolt makes selecting the right battery easy. Whether you choose a low priced battery such as the AGM or an innovative and technologically advanced Lithium Ion battery, Mastervolt offers you the right solution for the power you expect.

To make the choice even simpler, Mastervolt has divided its entire battery range of 31 types into six series and four different battery technologies. Each series has specific benefits as well as variations in price, capacity, dimensions, volume and lifespan.

All Mastervolt batteries offer you these advantages:

  • Maintenance-free
  • Safe - no degassing
  • Easy to install
  • Designed for cyclic use (charge/discharge)
  • Two-year warranty

Issues to take into account:

  • Choosing the right battery charger guarantees the maximum lifespan for your batteries. For more information see www.mastervolt.com/chargers. Mastervolt’s modern 3-step+ charge technology charges your batteries safely and quickly.
  • A battery monitor is the best way to make the most of your batteries.  Go to www.mastervolt.com/batterymonitor for more information.
  • Determining the correct battery capacity for your new battery/batteries is very important. 

Reinforced batteries

All Mastervolt batteries are equipped with shock-proof positive and negative battery plates with rubber separation, while the electrolyte is absorbed in gel or glass fibre (AGM). A high-grade lead/calcium compound guarantees a constant capacity and minimum self-discharging. Mastervolt has the right battery for every application.
