CCA stands for Cold Cranking Amps and is the recognised industry standard for rating a battery's cranking performance. The number of plates was once used as the measure for rating batteries, however CCA is now the industry standard.
AGM stands for Absorbent Glass Mat. This type of battery uses a non-woven glass mat to separate the plates. The glass mat absorbs and retains sufficient electrolyte for the battery to operate, meaning that there is no free electrolyte in the cell to spill. These batteries are also known as Valve Regulated Lead Acid (VRLA) batteries as each cell has a one-way valve to manage cell pressure.
Enhanced Flooded Batteries (EFB) are being fitted to many vehicles fitted with Idle Stop Start (ISS) technology. These ‘flooded’ batteries are an enhanced version of the standard calcium battery, and are designed to withstand the increased cranking and cycling demanded by vehicles fitted with ISS technology.
Idle Stop Start (ISS) technology, also known as Stop Start, is designed to help reduce vehicle fuel consumption and emissions. The vehicle’s engine automatically shuts down when the vehicle is stationary instead of idling, and will restart when you need to move again. ISS equipped vehicles are fitted with EFB and AGM batteries which are designed to cope with the additional electrical loads and repeated cranking required from this technology.
Some vehicles are equipped with Battery Management Systems (BMS) which require new batteries to be registered with the system. In most instances, RACV Batteries technicians will perform this registration on applicable vehicles.
RACV offers a 4WD range which come with a two-year warranty and installation. This includes higher cold-cranking amps for greater starting power, hot-melt glue over the plates to prevent vibration damage and leading maintenance technology to eliminate acid leakage.
RACV's Mobile Battery Service has a range of marine batteries specifically for your boat or yacht. We can deliver to your docked boat in metropolitan Melbourne or Geelong. This service does not include battery installation. Find out more.
What is CCA?
The industry-recognised standard for defining starting power is Cold Cranking Amps (CCA). Higher-rated CCA batteries will last longer and perform better in all vehicles than a lower CCA-rated battery.
