Terminology
Series vs Parallel
When researching your next battery purchase, you have probably come across the terms ‘series’ and ‘parallel’. Yet, you may find yourself asking – What do these terms really mean, and how do they affect my battery’s life and performance? For one, when...
Ampere (A)
A unit of measurement for electron flow or current through an electrical circuit. (Amp = Volt / Ohm)
Ampere-Hour (AH)
A unit of measurement for electron flow or current through an electrical circuit for a certain period of time. (Ampere X Hour = Ampere-Hour).
Electrolyte
In a lead acid battery, it is a dilute solution of sulfuric acid (H2SO4) and water.
Hydrometer
A tool used to measure the specific gravity of the electrolyte solution.
Ohm (Ω)
A unit of measurement for electrical resistance within an electrical circuit. ( Ohm = Volt / Ampere )
Ohm's Law
Expresses the relationship between voltage ( volts ), current ( amperes ), and resistance ( ohms ). (Ohms = Volts / Amperes).
Open Circuit Voltage
The voltage of a battery when there is no load attached ( not receiving or delivering energy). This measurement is best taken when the battery has been at rest for at least 6 hours.
Parallel Connection
A method of wiring batteries together by connecting the positive terminal of the first battery to the positive terminal of the second and the negative terminal of the first to the negative of the second. The capacity for batteries connected in parallel becomes additive, while the voltage remains the same as the individual battery.
Primary Battery
An energy storage device that can deliver energy but cannot be recharged.

Exide-Branded Battery Warranty
My battery failed; what should I do?
Most batteries that fail are simply discharged and need a boost. Batteries must first be tested to determine the cause of failure. If the battery is simply in need of a boost, have it re-charged and re-tested. If the battery is still not working properly, you may qualify for Battery Systems Inc. Limited Warranty for Exide-branded batteries.
Where can I have my battery tested?
Most auto parts retailers offer battery testing free of charge. Simply take your battery to any retailer which offers this service and obtain a printout of the test results. No free replacement battery or reimbursement (as applicable) will be provided unless a battery test receipt is provided.
How do I find out if my battery is still under warranty?
Complete details for determining the warranty eligibility can be found within the Battery Systems Inc. Limited Warranty policy and the Battery Systems Inc. PRO-RATA Limited Warranty policy, as applicable.
