1. There are two main types of sealed lead acid batteries - gel and
AGM. AGM, or absorbed glass mat, batteries are considered one of
your best options when you are looking for superior performance
and reliability. This type of battery uses, as the name suggests, a
glass mat to absorb the acid.
As mentioned, the performance and reliability of an AGM battery is
top notch. This type of battery is lightweight, spill-proof and
maintenance free. You don’t have to top off the water like you do
with flooded batteries. They are considered safer than other
options, too. Built up pressure is automatically released, thus
greatly reducing the chance of explosion.

2. Safe doesn’t mean a trade-off in performance, though. They are able
to deliver high currents when needed and have a charge that is
much faster than other battery types. They are great for vehicles
with a lot of accessories, like heated seats, that use a lot of power.
The construction of the AGM battery means it has some unique
benefits over traditional flooded batteries. They can handle cold
temperatures well because they do not have liquid electrolyte that
can freeze and crack the battery case. They also don’t require a flat
service for installation and handle weird angle installations easily.
Not to mention that vibration doesn’t bother AGM batteries, which
is why the sports car racing industry uses them. Also, AGM batteries
are easy to store and won’t lose their charge like flooded batteries.

3. Of course, nothing is perfect. AGM batteries do have some
limitations. Mainly, this type of battery doesn’t react well to heat.
They need installed away from the engine, and operation in hotter
temperatures will need lower voltages. Also, AGMs are susceptible
to overcharging. This type of battery is also rather pricey compared
to flooded batteries, but they usually cost less than gel batteries. In
addition, while AGM batteries are great for high bursts of energy,
they don’t perform as well for longer periods. Finally, they need to
be charged before they drop to 70% capacity and never allowed to
lose complete charge. Losing charge will greatly decrease the life of
the battery.
Absorbed glass mat batteries have only been around since the
1970s, but they have garnered a lot of fans. While this type of
battery has many advantages, the limitations still need to be
considered to ensure that this type of battery will effectively meet
your needs. To learn more about absorbed glass mat sealed lead
