Bateria AGM 6 V 400 Ah

The Mastervolt 6/400Ah battery uses AGM (Absorbed Glass Mat) technology. In this type of battery, the electrolyte (a mix of water and sulfuric acid) is largely absorbed into the fiberglass, ensuring maintenance-free operation and no gas release during normal use.

This battery has a nominal voltage of 6 volts and a nominal capacity of 400 Ah measured over 20 hours (C20).

The battery weighs 53 kg. Its dimensions, including terminals and handles, are 295 mm (length) x 180 mm (width) x 428 mm (height).

The cold cranking amps (CCA) of this battery is 620 A according to DIN standard and 1100 A according to SAE standard.

AGM batteries, like this Mastervolt model, offer several key advantages for marine applications:

They are maintenance-free and do not release any gas during normal use, allowing for versatile installation. Their design enables rapid discharge at high currents, making them ideal for systems requiring high power, particularly for engine starting. They provide an alternative in terms of placement and footprint compared to traditional batteries.

Yes, Mastervolt AGM batteries are delivered ready for use. It is important not to open the valves and never add acid or distilled water.

The permitted operating temperature range for this battery is –20 to 55°C. The nominal operating temperature is 5 to 35°C, and the recommended temperature to optimize battery life is 25°C.

Battery lifespan is halved for every 10°C increase above the recommended 25°C. Lower temperatures, on the other hand, will reduce the battery’s available capacity.

Yes, it is recommended to leave at least 1 cm (0.5 inch) of space between batteries during installation.

It is crucial to keep the battery away from heat sources to ensure proper operation and extend its lifespan.

The recommended torque for terminal connections is 16.0 to 20.5 Nm (145 to 180 InLbs).

To safely connect the battery, follow these steps:

Inspect the battery for any mechanical damage before installation.Clean the terminals before connecting.Ensure all loads and chargers are turned off during installation.Use reliable and properly sized cable lugs and battery terminals.Tighten all connections to the recommended torque.Connect the battery following the correct polarity.Connect the negative cable last.Use terminal protection covers for the battery terminals.

This battery is fitted with type A terminals with M10 threading, making it compatible with all standard battery terminals.

Yes, it is possible to connect this battery in series or in parallel with other batteries. However, it is imperative that all connected batteries are of the same brand, type, capacity, and state of charge. Do not mix old and new batteries.

Only chargers with an IUoUo characteristic should be used. Recommended voltage settings are:

Float charge: 6.90V at 25°C. Absorption charge: 7.13V at 25°C (for a maximum of 5 hours). A temperature-compensated charge (–15mV/°C) is strongly recommended.

This Mastervolt AGM battery comes with a two-year warranty.

Opening the battery valves will void the warranty. It is also important never to add acid or distilled water to the battery.

To ensure the longevity of your battery, regular maintenance is required:

Check batteries and connections at least every three months. Immediately correct any defects such as loose or corroded connections.Maintain the battery in a charged state. If the open-circuit voltage drops below 6.2 Volts, the battery must be recharged.Avoid deep discharges (regularly exceeding 50% of the rated capacity is not recommended) and recharge the battery immediately after discharge.Keep the battery dry and clean using only a soft, damp cloth. Never use additives, acids, or abrasive products.
