i would say best would be something like the mastervolt Lithiium batteries. . Many many cycles, much deeper discharge, 70% lighter and much smaller in space.

If you buy a quality US made battery like Northstar or Odyssey, they use almost pure lead (99.9%). It doesn't matter if it's recycled or not, as long as it is properly processed. When you buy a cheap Chinese made battery, who knows what else goes into the lead.

so here Ia the thing. It’s not cheap Chinese that you should be worried about. It’s cheaply made period. Because there are shit made US ones that are represented as well. And there are well made Chinese things as well. Hell, I would venture a guess you own quite a bit of Chinese made stuff and some lt is pretty good.

Thanks, I will check them out. I don't think most battery manufacturers spend the extra money to purify their recycled lead. It is obvious something is going on because overall battery life is poor compared to years past.

I am replacing my Odyssey batteries one by one now, so disappointed they only lasted 12 years. Oh well, if they last another 12 I guess its worth the extra $$$.

I need to replace both cranking batteries on my boat and would like to reduce the weight in the stern where they are stored. Who makes light weight cranking batteries?

+1 on the X2 Power AGM from Batteries Plus. Identical specs as Odyssey, but with an extra year of warranty. On the third season with mine.

I am looking to replace all four before any failure provokes an immediate ‘what’s available’ type purchase.
Your house is 24V? Or are your two house batteries actually linked in parallel, still at 12V? Single 12V 3-bank charger?

Best I've found is Odyssey for cranking batteries -- 12 seasons on one set, still going strong at 10 seasons on the second set -- and Lifeline. We replaced the 12-year-old Odyssey banks with Lifeline on it's own charger now, 3rd year... no long term verdict yet.

The two use different charging voltages, so you probably need to start with ideas about what your charger will do. In most cases, and even if you can pick and choose freely or specify your own parameters, once programmed your charger will only follow one specific set of bulk/absorption and float voltages... an argument for all four batteries being from the same maker.

Just FYI, I took the last Odyssey battery home and put it on the charger here at the house, wholla, brought it back to life. Now I have a spare..... I was just impressed, that's all....
