GLOSSARY
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 fl ooded 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 recommend-ed.
• Connections must be retorqued and the batteries should be cleaned periodically.
What is an AGM battery?
An AGM battery is a 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 fi bers.
• uses a recombination reaction to prevent the escape of hydrogen and oxygen gases
normally lost in a fl ooded 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.

LOW
NORMAL
Charging system low when test with accessory
loads
The alternator is not providing suffi cient current
for the system's electrical loads and the charging
current for the battery. Check the belts to ensure
the alternator is rotating with the engine running.
If the belts are slipping or broken, replace the
belts and retest. Check the connections from the
alternator to the battery. If the connection is loose
or heavily corroded, clean or replace the cable and
retest. If the belts and connections are in good
working condition, replace the alternator.
Charging system normal when test with
accessory loads
The system is showing normal output from the
alternator. No problem detected.
