Hey gang,
The battery in my TL is on it's last legs (no idea how old it is, it was in the car when I bought it 25 months ago); my plan all along has been to throw a new AGM 24F battery into it and call it a day. Prior to pulling the trigger on the new battery, I thought I'd do a little research, and said research has given me pause.

- Per my research, relatively late model cars have circuitry to prevent overcharging AGM batteries, the 3G TLs have no such safeguards.
- When an AGM battery is overcharged, and once the hydrogen catalyst has been consumed, overcharging will end the life of the battery in pretty short order.
- As a general rule, AGM batteries are pretty good plug in replacements for flooded lead acid batteries, but only for cars which make a lot of short trips.
- When an AGM battery is used in a car not designed for that type of battery, the battery will typically have a very short life if the car it is in does lots of long-distance highway driving.
- Should I simply stop overthinking it and put a wet battery in?
- Is there a relatively easy way to enhance the TL's charging system to play nice with an AGM battery?
- And most importantly, for those of y'all who've already taken the plunge into the AGM world, what has your experience been?
