● 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, different from 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.
● Gel Cell Battery (Gel) & VRLA Battery:
Gel batteries are similar to flooded batteries. Although
for this type, calcium replaces the antimony in the lead
plates, and silica is added to the electrolyte solution,
turning the liquid into a gel.
● Absorbent Glass Mat Battery (AGM):
AGM batteries are designed to deliver powerful bursts
of starting amps and run for a long time. ""Absorbed
Glass Mats"" are used to cushion the ultra-thin lead
plates, allowing manufacturers to include more leads
into one battery and provide more power. AGM
batteries are divided into two categories according to
the cell structure. They can be AGM FLAT PLATE and
AGM SPIRAL (See Figure 4.1.4). This type of battery is
ideal for vehicles with automatic start-stop applications
and braking energy recovery.
