(This glossary is a work in progress… we have tried to define the terms in the most simple and meaningful way for the largest number of readers. If any definitions are unclear or incomplete, kindly accept our apologies. If you disagree with any of the definitions, please let us know so that we can review)

AMPERE:

·         A UNIT OF MEASUREMENT FOR ELECTRICAL CURRENT.

AMPERE-HOUR (AH):

·         A UNIT OF MEASUREMENT FOR BATTERY CAPACITY.

COLD CRANKING AMPERE (CCA):

·         THE AMPERE THAT A FULLY-CHARGED BATTERY AT -17.8°c CAN DELIVER FOR 30 SECONDS AND MAINTAIN A VOLTAGE OF 1.2 VOLTS PER CELL OR HIGHER.

CYCLE:

·         ONE SEQUENCE OF CHARGE AND DISCHARGE.

DRY CHARGED BATTERY:

·         TYPE OF BATTERY IN WHICH THE BOTH POSITIVE AND NEGATIVE PLATES ARE FORMED AND CHARGED IN ACID BATHS BEFORE BEING DRIED AND ASSEMBLED. THE BATTERY IS ACTIVATED WHEN THE ELECTROLYTE (SULFURIC ACID) IS FILLED. THE BATTERY WILL GIVE INSTANT CURRENT AND BE READY FOR USE.

ELECTROLYTE:

·         FOR LEAD ACID BATTERY PURPOSES, THIS IS A DILUTE SOLUTION FO SULFURIC ACID AND WATER… (H₂SO₄)

FLOATING CHARGE:

·         METHOD OF RECHARGE WHEREBY A CELL IS CONTINUOUSLY CHARGED AT A CONSTANT VOLTAGE – SO THAT THE CELL IS MAINTAINED IN FULLY CHARGED CONDITION.

HYDROMETER:

·         INSTRUMENT USED TO MEASURE THE SPECIFIC GRAVITY OF THE ELECTROLYTE.

OPEN CIRCUIT VOLTAGE:

·         THE VOLTAGE OF A BATTERY WITHOUT ANY LOAD (I.E. NOT RECEIVING OR DELIVERING ENERGY).

RESERVE CAPACITY:

·         THE NUMBER OF MINUTES THAT A FULLY CHARGED BATTERY CAN BE DISCHARGED AT 25 AH AND MAINTAIN A MINIMUM OF 1.25 VOLTS PER CELL.

SEPARATOR:

·         A DIVIDER MADE OF POROUS MATERIAL PLACED IN BETWEEN THE POSITIVE AND NEGATIVE PLATES TO ALLOW CURRENT FLOW WITH OUT DIRECT CONTACT OF PLATES WHICH WOULD CAUSE A SHORT CIRCUIT.

SPECIFIC GRAVITY:

·         THE DENSITY OF A SOLUTION RELATIVE TO THE DENSITY OF WATER.

VOLT (V):

·         A UNIT OF MEASUREMENT OF ELECTRICAL ENERGY WITHIN AN ELECTRICAL CIRUIT.

WET CHARGED BATTERY:

·         SIMILAR TO DRY CHARGED BATTERY, HOWEVER THE BATTERY IS FILLED WITH ELECTROLYTE AT THE FACTORY AND READY TO USE BY COMPLETION OF MANUFACTURING PROCESS.
