A battery provides a charge of electricity that is utilised by the starter motor and ignition system so the engine can turn over and start. The battery then maintains a constant electrical charge to keep it going, along with any extra power required when a car’s electrical system needs are more than the alternator is capable of supplying.

1491-2012 – IEEE Guide for Selection and Use of Battery Monitoring Equipment in Stationary Applications

Operational parameters that may be observed by battery monitoring equipment used in stationary applications and the relative value of such observations are discussed in this guide. Although a list of commercially available systems is not given, a means for establishing specifications for the desired parameters to be monitored is provided.

IEEE 1187-2013 – IEEE Recommended Practice for Installation Design and Installation of Valve-Regulated Lead-Acid Batteries for Stationary Applications

This recommended practice provides guidance for the installation and installation design of valve-regulated lead acid (VRLA) batteries. This recommended practice is intended for all standby stationary installations. However, specific applications, such as emergency lighting units and semi-portable equipment, may have other appropriate practices and are beyond the scope of this recommended practice. Alternative energy applications are not covered.

1188-2005 – IEEE Recommended Practice for Maintenance, Testing, and Replacement of Valve-Regulated Lead-Acid (VRLA) Batteries for Stationary Applications

BATTERY TESTING AND INSTALLATION We'll swap out your old battery and install the new battery, free with purchase! Plus, we offer free battery testing and will charge any automotive or marine battery, too!

This recommended practice is limited to maintenance, test schedules, and testing procedures that can be used to optimize the life and performance of valve-regulated lead-acid (VRLA) batteries for stationary applications. It also provides guidance to determine when batteries should be replaced.

New guidance to users dealing with premature capacity failures with VRLA batteries and updated definitions are addressed in 2014’s amendment.

450-2010 – IEEE Recommended Practice for Maintenance, Testing, and Replacement of Vented Lead-Acid Batteries for Stationary Applications

Maintenance, test schedules, and testing procedures that can be used to optimize the life and performance of permanently installed, vented lead-acid storage batteries used for standby service are provided. This recommended practice also provides guidance to determine when batteries should be replaced. This recommended practice is applicable to standby service stationary applications where a charger maintains the battery fully charged and supplies the dc loads.

1106-2015 – IEEE Recommended Practice for Installation, Maintenance, Testing, and Replacement of Vented Nickel-Cadmium Batteries for Stationary Applications

This recommended practice provides recommendations for installation design and for installation, maintenance, and testing procedures that can be used to optimize the life and performance of vented nickel-cadmium batteries, including partially recombinant types, used in stationary applications.

Annex H: Internal ohmic measurements – “Internal ohmic measurements (see Clause 3) provide a means to assess the electronic and ionic conduction paths within a cell. These measurements are used for detection of cell abnormalities and to assess changes over time.”

446-1995 – IEEE Recommended Practice for Emergency and Standby Power Systems for Industrial and Commercial Applications

This Recommended Practice addresses the uses, power sources, design, and maintenance of emergency and standby power systems.

IEEE 1561-2019 – IEEE Guide for Optimizing the Performance and Life of Lead-Acid Batteries in Remote Hybrid Power Systems

This guide is applicable to lead-acid batteries that are used as the energy storage component in remote hybrid power supplies. The remote hybrid application, with its dual generator option, i.e., both renewable and dispatchable generation, is advantageous in that the battery can usually be charged at will and under circumstances that may also be advantageous for the dispatchable generator.

IEEE 1657-2018 – IEEE Recommended Practice for Personnel Qualifications for Installation and Maintenance of Stationary Batteries

The areas of recommended knowledge for installers and maintainers of stationary batteries and related systems, to the extent that they affect the battery, are defined in this recommended practice. Only lead-acid and nickel-cadmium battery technologies are covered in this recommended practice. An outline (not necessarily in training order) of the items that should be covered by training programs for stationary battery installation and maintenance personnel is provided.

Don’t get caught out with a flat battery! We can help keep you fully charged.

Your car battery is an important element of your car, it's a source of energy to start your ignition and it provides power to car accessories.

What does a car battery do?

While car battery technology has changed over the years, the primary function of the battery hasn’t. A battery provides a charge of electricity that is utilised by the starter motor and ignition system so the engine can turn over and start. The battery then maintains a constant electrical charge to keep it going, along with any extra power required when a car’s electrical system needs are more than the alternator is capable of supplying.

The battery also acts as a voltage stabilizer in the electrical system and smooths out any transient voltages that may occur. The battery also supplies power to items like the ECU, radio and clock when the vehicle is not being used.

Commonly asked questions about car batteries

Why does my car battery go flat?

Free Battery Testing And Installation Tool

Like any part in your car, your battery has a lifespan. As batteries age they slowly lose capacity simply through general use. In addition to this, electrical shorts can occur, components can corrode over time and vibration can also cause damage. The average age of a passenger car battery is about 42 months. In addition to general age, the following issues can impact battery life:

Accidentally leaving the lights on, including the interior lights
Items like dash cams can also run down the battery when the car is off
Lots of short trips can mean the battery doesn’t get the opportunity to recharge
Vehicles sitting unused for long periods of time will shorten the battery life

Having your battery tested regularly can save you a lot of time and hassle by identifying the potential life left in your car’s battery.

Can I put any battery in my car?
