Battery
A sealed-type battery is installed in the Hydrospace S4 Standup. After the enclo-
sed electrolyte has been filled into the battery for the first time, the sealing strip
must not be removed again. It is not necessary to check the electrolyte level of
the battery or to add distilled water. The battery is maintenance-free!
You must however, maintain the charge of the battery as intended in order to
maximize the life of the battery and to guarantee that the battery will supply the
current necessary for starting your S4 Standup. When used regularly, the
charging system helps to maintain the full charge of the battery. However, if
your S4 Standup is only used occasionally, the battery might possibly get
discharged.
Batteries get discharged on their own because of the way they are built. The
reason for the discharge depends on the type of battery and the ambient
temperature. When the temperature rises, the degree of discharge will increase.
