I realize there are several threads out there currently but most are a decade old. I'm not sure the protocol for refreshing a conversation, but hopefully my noob status will afford me some leniency.
Here is the series of events: My lights started to dim at night a few weeks ago and I assumed that meant my alternator was going or I have some sort of electrical issue (battery is new). As I looked around online I saw there are more powerful alternators available, but really what I needed was more storage (I realize this is all dependent upon the accessories drawing power, but I'm planning on adding a winch and more lights so I think it applies). I then stumbled across the dual-battery threads with a lot of suggestions, components, vendors, and advice but all are fairly dated and I wasn't able to draw a conclusion. So, here is what I've garnered thus far:
Thanks in advance,
Kevin

So, here is what I've garnered thus far:
- A dual battery setup should have a starter battery and an accessory battery. The first for engine starting power, the second for longer term power for accessories.
- Back in the day, Optima Red and Yellow top batteries were the answer, but they appear to have lost the confidence of the community
- Regardless of battery choice, I'll need a tray and a dual-battery system like the IBS (Intelligent Battery System) that has components that tie the batteries to the alternator, and their respective power drawing components
- A savvy mechanic can build their own system with easily available parts (probably not me)
- Apparently there is room for a dual setup if there hasn't been a V8 upgrade (My 2F is still in place)
- Which battery combo is best?
- Which system is best?
- Should I upgrade my alternator anyway?
Thanks in advance,
