- Yuasa Battery, Inc. Automobile Battery Charger User Manual

Let’s look first at battery basics: what a
battery is and how it works.
Lead acid batteries are used as a power source for vehicles
that demand a constant and uninterruptible source of
energy. Just about every vehicle today does. For example,
street motorcycles need lights that operate when the
engine isn’t running. They get it from the battery.
Accessories such as clocks and alarms are battery-driven.
The Lead Acid Battery
Starting your vehicle depends on a battery.
Technically speaking, the battery is an electrochemi-
cal device that converts chemical energy to electrical
energy. The first thing you notice inside a battery is
the cells. Each cell has about two volts (actually,
2.12 to 2.2 volts, measured on a DC scale). A 6-
volt battery will have three cells. A 12-volt battery,
six cells.
HEAT SEALED CASE TO COVER
protects against seepage and
corrosion – bonded unit gives extra strength.
THRU-PARTITION CONSTRUCTION
provides shorter current path with less resistance than
“over the partition” construction – you get more
cranking power when you need it!
SPECIAL
ACTIVE
MATERIAL
is compounded to
withstand vibration,
prolong battery life
and dependability.
PATENTED
SEALED POST
prevents acid
seepage, reduces
corrosion – extends
battery life.
POLYPROPYLENE COVER
AND CONTAINER
gives greater resistance to gas and oil –
and impact in extreme weather conditions!
SPECIAL SEPARATOR
provides high cranking power.
HEAVY DUTY GLASS MAT
resists shedding of active material even
under severe vibration.
SPECIAL GRID
DESIGN
withstands severe vibration,
assures maximum conductivity.
