I just 6 weeks back purchased a Duracell Ultra car battery for my wife's car at a great price online (25% off) and picked it up in the store. They installed it for free & they plug a power source into your diagnostic part to save all your settings. With the discount, it was $108 out the door & we got a $10 mail in rebate.
I am now a big Batteries + fan.

The plug in to the diagnostic port is a memory saver
They work good on most vehicles
I would hook up a battery or charger to the hot link to the alternator or starter this would keep the memory live especially on the trouble higher end cars
On Toyota models, DO NOT use the cigarette lighter outlet with 1 of these
9 out of 10 times it will give you an air bag or security lock out code

AGM from the factory, this is a trick question
Reason is AGM batteries are lead acid Read below
BU-201a: Absorbent Glass Mat (AGM)
Learn what differentiate AGM from other lead acid battery types
AGM technology became popular in the early 1980s as a sealed lead acid battery for military aircraft, vehicles and UPS to reduce weight and improve reliability. The sulfuric acid is absorbed by a very fine fiberglass mat, making the battery spill-proof. This enables shipment without hazardous material restrictions. The plates can be made flat to resemble a standard flooded lead acid pack in a rectangular case; they can also be wound into a cylindrical cell.
AGM has very low internal resistance, is capable to deliver high currents on demand and offers a relatively long service life, even when deep cycled. AGM is maintenance free, provides good electrical reliability and is lighter than the flooded lead acid type. While regular lead acid batteries need a topping charge every six months to prevent the buildup of sulfation, AGM batteries are less prone to sulfation and can sit in storage for longer before a charge becomes necessary. The battery stands up well to low temperatures and has a low self-discharge.
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. AGM offers a depth-of-discharge of 80 percent; the flooded, on the other hand, is specified at 50 percent DoD to attain the same cycle life. The negatives are slightly lower specific energy and higher manufacturing costs than the flooded, but cheaper than the gel battery.
Most AGM batteries are mid-sized and range from 30 to 100Ah. They can also be found in UPS, big and small for stationary and deep cycle use. They are commonly built to size and are found in high-end vehicles to run power-hungry accessories such as heated seats, steering wheels, mirrors and windshields. NASCAR and other auto racing leagues choose AGM products because they are vibration resistant.
AGM is the preferred battery for upscale motorcycles. Being sealed, AGM reduces acid spilling in an accident, lowers the weight for the same performance and allows installation at odd angles. Because of good performance at cold temperatures, AGM batteries are also used for marine, motor home and robotic applications.
AGM is making inroads into the start-stop function of cars. The classic flooded type is simply not robust enough and repeated cycling causes a sharp capacity fade after only two years of use. (See BU-806a: Heat, Loading and Battery Life.)
As with all gelled and sealed units, AGM batteries are sensitive to overcharging. A charge to 2.40V/cell (and higher) is fine; however, the float charge should be reduced to between 2.25 and 2.30V/cell (summer temperatures may require lower voltages). Automotive charging systems for flooded lead acid often have a fixed float voltage setting of 14.40V (2.40V/cell); a direct replacement with a sealed unit could overcharge the battery on a long drive. (See BU-403: Charging Lead Acid.)
AGM and other sealed batteries do not like heat and should be installed away from the engine compartment. Manufacturers recommend halting charge if the battery core reaches 49°C (120°F). Table 1 spells out the advantages and limitations of AGM.
AdvantagesSpill-proof through acid encapsulation in matting technology
High specific power, low internal resistance, responsive to load
Up to 5 times faster charge than with flooded technology
Better cycle life than with flooded systems
Water retention (oxygen and hydrogen combine to produce water)
Vibration resistance due to sandwich construction
Stands up well to cold temperature
Less prone to sulfation if not regularly topping charged
Has less electrolyte and lead than the flooded version LimitationsHigher manufacturing cost than flooded
Sensitive to overcharging (AGM has tighter tolerances than gel)
Capacity has gradual decline (gel has a performance dome)
Low specific energy
Must be stored in charged condition (less critical than flooded)

I was joking as indicated by the emojis. You didn't offend me at all.
I do think you should start an oil thread & ask Jack which engine oil he thinks is best. He LOVES oil threads! Don't forget about transmission & differential lubes also.
It's not just Jack, everyone loves oil threads.

By the way, Battery Mart has the Mega Crank 420 CCA battery for $89.99 + free shipping.

I have been researching replacement batteries further & I have selected a new contender in the AGM category as I'm not considering lithium.
My top choice based on quality & value is the Yuasa GYZ32HL. It is very well constructed with 32ah, 500 CCA & I have found it for $128 with free shipping. These are also USA made.
Feel free to comment. The link below shows a cutaway view of the battery.
