MVG 12/25 (gel)

In gel batteries, the electrolyte is bound in a gel. This type of battery is completely maintenance free, there is no gas formation during normal use. As no additional ventilation is required, gel batteries can be installed anywhere. They are ideal as a service battery and for cyclic applications. They can also be recharged very quickly.

  • Perfect service battery for medium and large 12 V and 24 V systems.
  • Exceptionally long life.
  • No gas formation during normal use.
  • Fast recharge, high charge current possible.
  • For intensive cyclic use with a large number of charge/discharge cycles.
  • Very low self discharge.
  • High return on investment.
  • Two-year warranty, under extended conditions.

AGM 12/55 (group 24)

In AGM batteries, the electrolyte (mixture of water and sulphuric acid) is mostly bound in a glass fibre mat. This type of battery is completely maintenance free and there is no gassing under normal use. In addition, these batteries can be installed anywhere.

Due to their construction, they are discharged very quickly at very high current consumption, which makes AGM batteries ideal for systems with high current consumption (for example, when starting the engine). The battery terminals can be unscrewed. This type of battery can be combined with any standard battery terminal.

  • Excellent starting ability.
  • Perfect upgrade from wet lead acid batteries.
  • The initial peak current of a 12/90 Ah AGM matches a wet lead acid battery of 180 Ah.
  • Fiberglass technology ensures low internal resistance.
  • Can be combined with any standard battery terminal.
  • Also suitable for medium cyclic applications.
  • Two-year warranty, under extended conditions.

Battery Mate 1602 IG

On-board systems usually consist of two or more batteries that operate independently when supplying power to 12 or 24 V consumers. These batteries require independent charging with reliable battery isolators or battery combiners.

Mastervolt offers several intelligent solutions:
  • Battery isolating diodes that share your charge current with minimal energy loss.
  • Charge Mate for connecting/disconnecting two batteries.
  • Battery Watch to monitor the condition of your batteries (can also be used as a main switch).
Battery Mate battery isolators with very low voltage drop
While BI battery isolators are conventional diode splitters, the Battery Mate's technology is electronic and incorporates MOSFETS (transistors). Its components compensate for the voltage drop and ensure that charging continues at the correct voltage level, even with multiple battery banks.

The Battery Mate is compatible with any type of alternator/battery charger in both existing and new systems. As the voltage loss between the alternator and the battery is negligible, the Battery Mate has a much greater power capacity than conventional battery isolators. This ensures a fast and complete charge of your batteries without the need for additional modifications to the alternator.

Charging two or three high capacity batteries
The Battery Mate is the ideal solution for charging multiple batteries, possibly with other alternator brands whose charging voltage cannot be adjusted, and can charge two or three batteries with a high yield and without any voltage loss.

Models 1602/1603 are suitable for alternators with a maximum charging current of 160 amps, the Battery Mate 2503 is ideal for alternators with a maximum charging current of 250 amps.

Clear monitoring
Safety guaranteed: Battery Mate's LED display indicates whether the power input is active.

Robust and durable
Fully corrosion resistant material with aluminum heat sink, electronic components are encased in plastic.

Quick installation
Composite end plates are equipped with terminal lugs, solid screw terminals with nuts and lock rings guarantee easy installation.
