Glossary of Terms

Electrical testers can be used to measure parameters related to electrical systems integrity. For instance the measuring of insulation or resistance values can help to determine if something is grounded or insulated correctly.

A battery tester can be used to determine if a lead acid battery is good, bad or marginal.

Term	Definition
Ah	Amp x h, a standard unit to measure a battery's total capacity. It represents how much constant current (A) can be provided in an hour before the battery becomes insufficient in providing power. For example, 10Ah capacity means the battery can provide a 10A current continuously for an hour.
Battery Internal Resistance	Internal resistance represents the internal chemical behaviors of a battery in the form of electrical circuitry. It is often measured to determine the life of a battery, indicating whether a battery can recharge further for use or not.
Charge Capacity	Indicates the capacity of charge in a battery, which determines the amount of power a battery can provide before it is used up.
Lead Acid	Refers to the chemicals used for making a battery. Ideally, these are used for the type of batteries used in automobile.
Li-Ion	Abbreviation for lithium ion, is one of the most popular type of rechargeable batteries used today to provide longer lasting power than Ni-MH batteries for portable electronics such as cellular phones and laptop computers.
mAh	Milli-amp x h, a common unit of measure to indicate a battery's total capacity. This is often used to indicate capacity of consumer type batteries of type Ni-MH or Li-Ion.
Ni-MH	Abbreviation for nickel metal hydride, is a popular type of rechargeable batteries often used for powering portable electronic devices.
SLA	Sealed lead acid
