to the Yuasa Battery Specifi cations & Applications guide.
Yuasa offers a complete line of chargers to activate and
maintain batteries to factory specifi cations and all of
them are discussed in the next section.
1 AMP Automatic Battery
Charger & Maintainer
D e s i g n e d fo r l o ng te r m u s e , Yu a s a’s 1 AMP Automatic
Battery Charger & Maintainer uses “smart” battery
charger technology, is fully automatic and features
a three level charge cycle. These include:
■ Bulk Charge—concentrated charging power in the
constant current mode
■ Float Charge—maintains a fully charged battery
■ Pulse Mode—peaks battery capacity which enhances
battery life
When the initial charging mode reaches
14.4 volts the charger
switches to fl oat mode. If a load is applied to the battery
(turning on the vehicles ignition or lighting) during charging,
the charger automatically switches back to “charge” mode, then
to a maintenance fl oat charge. The
1 AMP Automatic Battery
Charger & Maintainer is designed for use with both AGM and
Conventional types of batteries,
plus it will not overcharge
even if left connected for long
periods of time. It also features
an AC power LED indicator,
full charger indicator,
battery fault indicator,
reverse
polarity
protection
and spark-free
operation. The
c h a r g e r plugs directly into
a wall outlet and comes with a
12-foot
output cord, battery accessory lead and fused ring connector.
The charger has a
5-year warranty. (For more information, see
page 2.)
Automatic 12V 4 Amp Battery Charger
The Yuasa Automatic 12V 4 Amp Battery
Charger can charge up to
20-volts to
aid in recovering deeply discharged,
sulfated batteries. It features a “Quick
Mode” for faster vehicle setup and
“Normal Mode” for smaller batteries.
The diagnostic function provides
information indicating that the battery
is damaged and will not accept a charge.
In addition, a reverse polarity connection
is indicated on the panel. (For more information, see page 27.)
10-Bank Battery Maintainer
For shop use where multiple batteries have to be maintained
the Yuasa
10-Bank Battery Maintainer is ideal. It will charge
and maintain
10 batteries (both Conventional and AGM) at
one time. The charger uses a
5-stage maintenance/fl oat charge
cycle that includes:
■ Pre-Qualifi cation—determines battery condition
■ Bulk Charge—concentrated charging power
■ Absorption—equalizes battery’s cell charge
■ Float Mode—safely maintains proper charge condition
■ 28-Day Charge Recycle—re-evaluates battery status for
long term storage
It also features a built-in timer for extra battery protection.
Each charging port has LED indicators for charging status. (For
more information, see page 27.)
Activating AGM Batteries
Activating an AGM battery is a simple process and differs
from activating a Conventional battery (covered later in this
section). Un-activated, AGM batteries can be stored
for long periods of time as long as they are kept in
a cool, dry location and out of direct sunlight. Also
the foil sealing strip covering the
fi ller ports should not be removed
until the battery is ready to
be activated. Use only the
electrolyte container
that comes with
the battery for
fi lling the cells
as it has a higher
concentration of
sulfuric acid than the acid
used for Conventional batteries.
