- For battery shipments, a €75 pallet delivery surcharge will apply.
Description
Mastervolt AGM Slimline batteries provide substantial battery capacity in an exceptionally narrow enclosure, making them an excellent choice for marine, mobile and off-grid installations where available floor space is limited.
The electrolyte is absorbed within a glass-fibre mat, creating a completely maintenance-free AGM battery. Under normal operating conditions, there is no gas formation, providing greater installation flexibility than conventional flooded lead-acid batteries.
Compressed AGM construction supports rapid discharge at high currents. This makes the Slimline range suitable for general service-battery applications as well as systems requiring high starting currents.
Compared with conventional battery formats, the Slimline design can save up to 15% in both volume and weight. Two 185Ah Slimline batteries can be installed within approximately the same footprint normally required by a single conventional 200Ah battery.
The batteries feature convenient removable M6 terminals and can be used with standard battery-terminal connections.
Information is based on the current Mastervolt AGM Slimline product range.
