Electrolyte Circulation
System (Airlift System)
SUNLIGHT Premium Battery Chargers (conventional 50Hz and High Fre-
quency Series) are designed to meet the most demanding traction battery
needs and on the same time minimize charging costs.
SUNLIGHT’s complete range of accessories is selected to facilitate your day-to-day busi-
ness. Our complete solutions can protect your batteries and vehicles, secure longer service
life and lower operating costs.
Automatic Filling System (A.F.S.) allows the user to top up the cells of
the battery from one central point through an integrated piping system,
installed on the battery. The automatic filling plugs ensure the optimum
filling level of the cells, minimizing the required maintenance time for
the battery.
Airlift System improves battery performance and extends battery service
life in heavy duty applications. The principle behind it, is that a pump is
used to circulate low-level compressed air into the cells and to create a
homogenous electrolyte mixture throughout them.
SUNLIGHT’s Battery Monitoring Systems range consists of advanced
technology systems which continuously monitor cycles, voltage, op-
portunity charging, electrolyte level and temperature of the battery. All
these important data can be viewed in graphs via internet. Our Battery
Monitoring Systems range can provide an accurate estimation of the
remaining service life of the battery.
SUNLIGHT’s Electrolyte Level Indicators are smart electrolyte moni-
tors that alert personnel when a battery needs water. Resistant to the
harshest environments, Blinkies improve battery maintenance and re-
duce operating costs.
