PERSONAL SAFETY PRECAUTIONS
2.1
Consider having someone close enough by to come to your aid when you work
near a lead-acid battery.
2.2
2.3
2.4
Have plenty of fresh water and soap nearby in case battery acid contacts your
skin, clothing or eyes.
Wear complete eye and body protection, including safety goggles and
protective clothing. avoid touching your eyes while working near the battery.
If battery acid contacts your skin or clothing, immediately wash the area with
soap and water. If acid enters your eye, immediately flood the eye with cold
running water for at least 10 minutes and get medical attention right away.
2.5
2.6
NEVER smoke or allow a spark or flame in the vicinity of a battery or engine.
Be extra cautious to reduce the risk of dropping a metal tool onto the battery.
It might spark or short-circuit the battery or other electrical part that may cause
an explosion.
2.7
2.8
remove personal metal items such as rings, bracelets, necklaces and watches
when working with a lead-acid battery. a lead-acid battery can produce a short-
circuit current high enough to weld a ring or the like to metal, causing a severe
burn.

WARNING: Working in the vicinity of a lead acid battery is dangerous.
Batteries generate explosive gases during normal battery operation. For this
reason, it is of utmost importance, if you have any doubt, that each time before
using your tester, you read these instructions very carefully.
2.10 to reduce risk of battery explosion, follow these instructions and those
published by the battery manufacturer and manufacturer of any equipment
you intend to use in the vicinity of the battery. Observe cautionary markings on
these items.
2.11 do not expose the tester to rain or snow.
3.
PREPARING TO TEST
1. Be sure the area around the battery is well ventilated while the battery is
being tested.
2. Clean the battery terminals. Be careful to keep corrosion from coming in
contact with your eyes.
3. Inspect the battery for a cracked or broken case or cover. If the battery is
damaged, do not use the tester.
4. If the battery is not a sealed maintenance free battery, check the level
of each cell and if necessary, add distilled water until the battery acid
reaches the level specified by the manufacturer. This helps purge
excessive gas from the cells. Do not overfill.
5. If it is necessary to remove the battery from the vehicle to test it,
always remove the ground terminal from the battery first. Make sure all
accessories in the vehicle are off to ensure you do not cause any arcing.

GLOSSARY
What is a SLI battery?
these initials stand for starting, Lighting and Ignition, which are the three basic
functions which a battery has to perform on all normal vehicles. Batteries
given this description, will have been specifically designed for service on cars
and trucks within a voltage controlled electrical system. Most Maintenance
Free Batteries are sLI, otherwise known as Flooded, regular or standard
Batteries.
What is a GEL battery?
a gel battery is a lead-acid electric storage battery that:
• is sealed using special pressure valves and should never be opened.
• is completely maintenance-free.*
• uses thixotropic gelled electrolyte.
• uses a recombination reaction to prevent the escape of hydrogen and
oxygen gases normally lost in a flooded lead-acid battery (particularly in
deep cycle applications).
• is non-spillable, and therefore can be operated in virtually any position.
However, upside-down installation is not recommended.
*Connections must be retorqued and the batteries should be cleaned
periodically.
What is an AGM battery?
an aGM battery is an absorbed glass mat lead-acid electric storage battery
that:
• is sealed using special pressure valves and should never be opened.
• is completely maintenance-free.*
• has all of its electrolyte absorbed in separators consisting of a sponge-
like mass of matted glass fibers.
• uses a recombination reaction to prevent the escape of hydrogen and
oxygen gases normally lost in a flooded lead-acid battery (particularly in
deep cycle applications).
• is non-spillable, and therefore can be operated in virtually any position.
However, upside-down installation is not recommended.
*Connections must be retorqued and the batteries should be cleaned
periodically.
What is a VRLA battery?
Valve regulated Lead acid Battery – this type of battery is sealed
Maintenance Free with a “Bunce” Valve or Valves in the top of them that opens
when a preset pressure is realized inside the battery and let’s the excess gas
pressure out. then the valve resets itself.
What is STATE OF HEALTH?
It means how much battery capacity is left (%) compared with the marked
original battery capacity.
What is STATE OF CHARGE?
It means to what percent the battery is actually charged.

What is CCA (COLD CRANKING AMPS)?
the current in amperes which a new fully charged battery can deliver for 30
seconds continuously without the terminal voltage falling below 7.2 volts (1.2
volts per cell), after it has been cooled to 0°F and held at that temperature.
This rating reflects the ability of the battery to deliver engine starting currents
under winter conditions.
What is AMPERE-HOUR?
the unit of measurement of electrical capacity. a current of one ampere for
one hour implies the delivery or receipt of one ampere-hour of electricity.
Current multiplied by time in hours equals ampere-hours.
