MVG GEL Battery 12V, from 55Ah to 200Ah Mastervolt

MVG GEL BATTERY 12V, FROM 55AH TO 200AH MASTERVOLT: POWER AND RELIABILITY FOR YOUR BOAT

The MVG GEL BATTERY 12V Mastervolt is a reliable and maintenance-free power solution for your boat. Its innovative design, based on the gelling of the electrolyte, offers excellent resistance to deep discharges and an increased lifespan.

SAFETY AND FLEXIBILITY

Thanks to its hermetic casing, this GEL BATTERY can be installed in confined spaces without risk of leakage or gas emission. The absence of maintenance and the possibility of installation in any position make it particularly suitable for mobile uses and demanding environments.

DURABLE PERFORMANCE

Designed for intensive cyclic use, the MVG Mastervolt battery is ideal as a service battery for boats and motorhomes. Its low self-discharge rate also makes it suitable for applications requiring a continuous power supply, such as alarm systems and solar installations. Although less suitable for high starting currents, it can be used as a replacement for a conventional lead-acid battery by checking the CCA value (cold cranking amps).

Overview of features:

• Minimal self-discharge (2% at 20° C)
• Can be used in confined spaces and close to people
• Hermetically sealed housing, therefore maintenance-free and leak-proof
• No gas formation in normal use
• Very fast recharge (high charging current, 50% of possible capacities)
• Ideal as a service battery with intensive cyclic use (high number of charges/discharges)
• Suitable for IUoUo characteristic chargers.

• Installation
  If several batteries are installed directly next to each other, a distance of > 1 cm should be maintained.
  *MASTERVOLT recommends installation in an upright position
• Charge
  • Use a 3-stage IU and temperature compensated charger
    (for a 12 V battery - 30 mV/°C)
  • Charging current: 10 up to max. 50% of nominal capacity
  • Absorption charge - 14.25 volts at 25° C (max. 5 hours)
  • Floating charge - 13.8 volts at 25° C
  • Tip: weekly recharge to 100%
  • Batteries should be charged when the open circuit voltage drops below 12.3 volts.
    (*The open circuit voltage measurement assumes that no further chemical processes are taking place in the battery, which is guaranteed if the battery has not been charged or discharged for approximately 3-5 hours).
• Discharge
  • Recommended DOD* 50%
    (*DOD = Depth Of Discharge - depth of discharge
  • Regular discharge of more than 60% of the battery's nominal capacity shortens its lifespan.
    The battery must be fully recharged immediately after being discharged.
  • The final discharge voltage must not fall below the value stated in the operating instructions (page 9).
    Important: The final discharge voltage depends on the discharge current.
• Operating temperature
  • Permissible operating temperature: - 20° to 45° C
  • Nominal operating temperature: 10 to 30° C
  • Recommended operating temperature: 20° C
    Note: The operating temperature has a great influence on the life of the battery.
    A 10° increase in operating temperatures alters the life of the battery; at low temperatures, the available capacity decreases.
  • Storage temperature: -40° to 55° C
