Battery Installation
In most applications, batteries should be installed in an
upright position, If there is any question regarding a particular
vehicle/battery/installation please contact us for our specifi c
recommendations before installation.
Yuasa AGM batteries that come with separate acid packs that
are used to fi ll and activate the battery should not be installed
in any position other than upright, as possible electrolyte
leakage may occur. Also, Conventional and YuMicron
batteries should never be installed in any position
other than upright as their liquid electrolyte will leak
from the battery case causing damage to the vehicle.
Disclaimer:
Yuasa batteries are to be mounted in a position identical
to the position in which they were mounted in the
vehicle by the manufacturer. Any position other than
the “
O°” position (upright) requires a “non-spillable”
“Factory Activated” battery.
Yuasa Battery assumes no responsibility for damages and/or
injuries incurred due to a battery being mounted in a position
other than what was originally used in the vehicle by the
manufacturer. All “-BS” and Conventional “Flooded” batteries
are to be mounted in the “
O°” (upright) normal/center position.
POINTS TO REMEMBER
■ The Yuasa Battery Specifi cations & Applications guide and
OE microfi che, or online parts look up data are the best
sources for battery applications information
■ When replacing a battery that uses an original equipment
sensor, always replace the sensor
■ Conventional and YuMicron batteries should never be
installed in any position other than upright as their liquid
electrolyte will leak from the battery case causing damage
to the vehicle
■ Yuasa batteries are to be mounted in a position identical to
the position in which they were mounted in the vehicle by
the manufacturer
Any position other than the “O°” position (upright) requires a
“non-spillable” “Factory Activated” battery While it may seem
obvious that testing a battery before replacing it would be
a good idea, often times a battery is unnecessarily replaced
only to fi nd that the charging system, or a loose battery cable
connection is the reason for the discharged battery. For
example, a motorcycle’s battery is discharged, or dead. The
owner (or dealer) replaces the battery and the engine easily
starts. The battery must have been the problem as bikes
starts consistently for a week. Eventually the battery becomes
discharged again and the owner is facing the same problem. If
the charging system on the motorcycle is weak, or there is a
loose connection in the electrical system, the new battery only
temporarily solved the discharge problem. Batteries should be
tested to avoid unnecessary replacement.
There are several methods used to test a battery. Measuring
state-of-charge after charging a battery can determine if the
battery is good. For Conventional batteries, a hydrometer can be
used to measure specifi c gravity and thus state-of-charge. For
both Conventional and AGM batteries, a voltmeter can measure
state-of-charge. Load testing is another method to determine if a
battery is good. All of these tests require that the battery be fully
charged before testing. The only method that does not require
a fully charged battery is using the Yuasa Digital Powersports
Battery Tester. This tool will be covered later in this section.
Inspecting a Battery
Battery testing should begin with an inspection of the battery
using the following steps:
1. Make sure the top of the battery case is clean and
dry. If the case of a battery is dirty it can cause the battery to
discharge through the grime on top of the case. Use a soft brush
and water and soap or a solution of baking soda and water to
clean the battery case or terminals. On a Conventional battery,
make sure fi ller cap plugs are fi nger tight so cleaning materials
will not enter the cells and neutralize the acid.
2. Inspect battery terminals, screws, clamps and cables
for problems including: breakage, corrosion or loose
connections. Clean the terminals and clamps with a wire
brush. Once battery cables are installed, dielectric grease
(available at most auto parts stores) or clear lacquer from a
spray can applied to the terminals will help prevent oxygen
from causing corrosion on the battery terminals.
3. Inspect the battery case for obvious damage such
as cracks or leaks; look for discoloration, warping or
raised battery case top, which may indicate that battery has
overheated or been overcharged.
