How to Identify What Type of Battery You Have? Let's take the following picture as an example: Manufacturers Part No. Battery Type Figure 3.2.1 1) Reserve Capacity: 80Ah The Reserve Capacity is a time measurement that explains how long a fully-charged battery can deliver a 25 amps current in an 80°F- environment before the battery is discharged and drops to 10.5 volts. 2) Battery Type: AGM Please refer to this list to check the most commonly seen lead- acid battery types for your reference. EN I 11 AGM 650 E51 80Ah 12v A (SAE) Reserve Capacity Voltage CCA in USA Reserve Capacity CCA in USA Flooded Lead Acid Battery (Wet):
This is the oldest/most common car battery type, also known as "SLI battery." The Flooded Battery is usually made of 6 cells with a liquid electrolyte solution of sulfuric acid and water that needs to be topped off periodically. This battery typically supplies a voltage of 12.6V at full charge. Enhanced Flooded Battery (EFB): This battery type also uses a liquid electrolyte solution. However, differently than the Wet Flooded Lead Acid, it is sealed and maintenance-free. The Enhanced Flooded, usually seen in cars with simple start-stop technology, can provide up to 85,000 engine cranks.
