For those who have upgraded their batteries what did you go with and why. Especially, those who have air suspension because stock just cant keep up with the power usage. Thank you for any responses.
The Lexus GS 350 takes a Group Size 24 battery. The original battery is rated at 580 CCA (Cold Cranking Amperes). It should be noted that hot/warm climates are far more damaging to vehicle batteries than cold/cool climates. Likewise, it is recommended that in hot/warm climates that the battery be load-test analyzed after it becomes two years old, and then retested annually each year thereafter. For cold/cool climates it is recommended that the battery be load-test analyzed after it becomes four years old, and then retested annually each year thereafter.
If you live in a hot/warm climate area do not make the mistake of choosing the highest CCA. The reason being - high CCA batteries are achieved by spacing the cell plates closer together, however high ambient heat can cause these closely spaced plates to weaken or sag, which can cause early battery failure (e.g. adjoining shorted cells). As the map below indicates Interstate Battery recommends their Mega-Tron II (600 CCA) battery for hot climates and their Mega-Tron Plus (800 CCA) battery for cold climates. As noted, a higher CCA is not the better choice for hot/warm climate areas.

How about getting a battery tender when you park it for long periods? Letting the battery drain too low(deep cycling) shortens the life of the battery.
