Most stock car audio systems will perform just fine with a good strong flooded lead acid battery. Some will require a good AGM battery under the hood. But, if you plan on installing a large amp, a sub-woofer and large speakers, you will need to upgrade your alternator, add a car audio battery or batteries, or do both.

The main difference between gel and AGM batteries is the charge rates. AGM batteries can handle higher charge and discharge rates than gel batteries. ... Gel batteries are more expensive than other lead-acid battery types, so they are not ideal outside a handful of specific solar applications (very hot climates, mainly).

Can my AGM battery be installed in any position? The AGM and Gel batteries can be mounted on their sides with no problems, but should not be mounted upside down. 7.

The Average Life Expectancy of An AGM Battery. Usually a typical sealed absorbent glass mat battery last three to five years. It can be extended up to six to eight years if the battery is properly maintained.

To grossly simplify, “gassing” lowers the battery's liquid electrolyte level. Hence, the need to periodically add water to it. However, AGM batteries literally water themselves by holding and recombining gases that traditional batteries discharge.

A standard car radio (our pick: SiriusXM SXPL1V1) will last in good condition for anything like 10-15 plus hours on a car battery. The most common way to deal with a dead battery is by jump-it.

A battery for a start-stop system can only be replaced with a battery of the same type. In the case of an EFB battery, an upgrade to an AGM may be advisable. However, under certain circumstances, an AGM battery may be suitable for vehicles without start-stop technology.

6 to 8 years is easily obtainable with proper maintenance. Typically sealed AGM batteries will give warning before completely dying. They will start slower, and require more charging. This is your clue to replace the battery.

AGM batteries are sealed, but they still off-gas. ... It simply can't be emphasized enough, regardless of the specific battery technology employed: batteries MUST be properly secured in place, and the compartment they are located in must provide adequate ventilation in the event of excessive gassing.

The leading advantages of AGM are a charge that is up to five times faster than the flooded version, and the ability to deep cycle. ... The negatives are slightly lower specific energy and higher manufacturing costs than the flooded, but cheaper than the gel battery.

Gel batteries a deep cycle durability that allows you discharge them up to 90% and still get a much better cycle life compared to AGM batteries. ... Of course, a higher cycle life doesn't come for free. Gel batteries are more expensive than standard AGM batteries, but they might be worth the investment when used properly.

Comparing the Two Battery Types Gel batteries tend to lose power faster than AGM batteries, especially at lower temperatures. ... When it comes to Depth of Discharge (DoD), Gel batteries make use of acid better than AGM batteries. Acid protects the Gel batteries' plates, enhancing their deep discharge applications.

Note voltage at 15 seconds and stop discharge. If voltage is less than 9.6 (normal temperature), replace battery. Fixed load test—Similar to BCI test except voltage limit depends on CCA rating. ... Many older-model battery testers cannot adequately test AGM batteries and could prematurely condemn a good AGM battery.

The short answer is that AGM stands for "Absorbed Glass Mat," which is a specific type of lead-acid battery. OPTIMA Batteries are considered SPIRALCELL AGM batteries. ... Just use the other setting, which is often labeled as "Regular" or "Starting" battery.

We can generally say an AGM battery can last two to three times as long as a flooded battery. In the commuter car example we referenced, if a flooded battery lasts three to five years, an AGM battery could last six to ten years or longer.
