I have been following the battery discussion and have a question. I need to replace my two 9 year old AGM batteries this season. I have separate start and house batteries which can be combined if needed. I don’t have large power needs (electronics, autopilot and fridge when cruising). I have been reading and researching this and I am unsure of what to purchase. From what I have read, AH is the important number to focus on. Last time, I got Lifeline AGM group 27 from Defender. Defender has 3 different group 27 batteries Powertech rated at 92AH which cost about $330 Lifeline rated at 100AH for 432 Northstar rated at 92AH for 457 From Amazon, I can get a VMAX group 27 with 100AH for $289 or a Universal with 110 AH for $239. Is there any reason to be concerned about less known (to me) brands from Amazon or does it make sense to just focus on the numbers? Thanks- Dave
