免维护SMF（密封免维护）VETUS电池具有终身电解液储液器。由于铅钙板和VRLA（减压阀）的特殊结构，水的消耗非常低，因此永远不需要重新填充。这些船用电池比传统电池轻约25%，小约40%。它们具有大约3%的低自放电率。大使用角度55°。非常适合用作船的启动电池或消费电池。

注：

连接：圆形SAE船用电池（在汽车行业通常被称为），将安装标准的电池端子夹。

在110 Ah以下的VETUS电池上，接线柱位于外壳的长侧。它们更深，配有与电池顶部齐平的折叠保护罩。

对于125 Ah VETUS电池，连接极位于窄侧和外壳上。

Maintenance-free SMF (Sealed Maintenance Free) VETUS batteries feature a lifelong electrolyte reservoir. Thanks to a special construction of lead-calcium plates and VRLA (pressure relief valve), water consumption is so low that refilling is never necessary. These marine batteries are about 25% lighter and 40% smaller than conventional batteries. They have a low self-discharge rate of approximately 3%. Maximum angle of use 55 °. Perfect for use as starter or consumer batteries for boats.

Note:

Connections: round SAE marine batteries (as commonly known by in the automotive sector), will fit standard battery terminal clamps.
On VETUS batteries up to 110 Ah, the terminal poles are located on the long side of the case. They are deeper and are equipped with folding protective covers that are flush with the battery top.
For 125 Ah VETUS batteries, the connection poles are on the narrow side and on the housing. (See picture, the PLUS connections have red covers.) The polarity is marked by embossing on the housing.

Notes on usage:

Voltage (20°C): Boost - 13,9 to 14,8 Volt, Float* - 13,2 to 13,8 Volt
(* = preservation charge)

IUOU-characteristics curve recommended,

max. DOD* 50%
ca. 350 cycles at 35% DOD*

(*DOD = Depth Of Discharge)

On VETUS batteries up to 110 Ah, a "magic eye" indicates the state of charge:

green = battery is charged

black = battery has to be charged

white = battery can not be used, check is needed
