What house batteries are you running?

[Serendipity Cutwater 28]

My AGM house batteries need to be replaced. Purchased 2023. What brand and amp hour are you running?

They shouldn't need to be replaced. Do a draw down. I run mine 7 years with no problem

My factory AGM batteries lasted 90 days before I sulfated and destroyed them. Everybody boats differently.
My hats off to you for getting 7 years out of a set of AGM batteries. My second set of AGM batteries lasted a little over a year. Then I converted my boat to LFP.

House = 4 X Lifeline 125 aH GPL-31XT
Starter & Thrusters: 2 X Lifeline Starting Marine/RV Battery The GPL-3100T
They all work great.

I've got three 105ah Duracell brand AGM from Batteries Plus. Had them for a year and been happy with them. The 3rd house battery makes a big difference.

+1 on the Duracells.

+2 on the Duracell's. 4 110 AH AGM Duracell Marine/RV Platinum's, and same batteries for one Start and one Thrust on the Stbd side. $2K all in. I also added 2 Renogy Flex panels on top of my Bimini, with a Renogy Rover 40 Amp Controller with Bluetooth for solar.

After 3 years, I switched to Lithium, EPOCH 460, some moderate system changes with the charging, but well worth it. Not only in weight, but performance.

Interesting, I just did exactly the same except 3x Lifelines on a 2019 boat.
