If batteries are looked after they should last a lot more than two years. There are various ways of killing a battery: leaving it discharged, using a deep cycle battery as a starter battery and vice versa, discharge too fast, over-charge, excessive vibration and so on. It is always worth checking all connection points carefully. I have had batteries giving a very good impression of being dead when in fact it was a corroded connector not at the battery terminal but further along the heavy duty cable.

I would replace both as at least then you know that they are both good, I would have thought they should last 3 years

Loads and loads of info on the net, but if you want the best then look at Optima.
Red, Yellow and Blue Tops..
The Yellow and Blue the same except the "Marine" Blue has extra terminals.
I could sing the praises and write ten pages of benefits and why you should use them, but truth be told someone will always pipe up with "Well a cheap battery has never let me down" so instead of me writing pages..
Google search Optima Battery.
use various search terms such as "Advantages of AGM battery" then go buy one.

You learn something new every day. Sounds good but I think I would want power from a battery even if it drops to 50% charge.

Which is why an AGM wins hands down every time.
DOD of AGM is rated 80% as opposed to flooded of 50%



Weeks worth of material can be found on these batteries.

I had one which showed 3.2 V...
Had that been flooded battery it would have had one use as scrap.. Not the AGM... Bought back to life and still going strong years later.

More expensive than flooded, but when at sea you cant get a bump start..

More of the power available without VD.
Use the same battery as starter and house (Yellow and Blue Tops).
Higher cranking power.
