mc6524 Posted December 30, 2019 Posted December 30, 2019 I’m looking to replace my duel purpose boat npbattery this year. I’m looking for a good AGM battery that lasts a long time. Any suggestions? Ive heard that the Odessey AGM is good, anyone have experience with this battery? Thanks Quote
Super User J Francho Posted December 30, 2019 Super User Posted December 30, 2019 my Optimas were five years old when I sold the boat. Still kicking, as far as I know. 2 Quote
Super User A-Jay Posted December 30, 2019 Super User Posted December 30, 2019 Like @J Francho - I'm running and happy with Optimas Specifically 31M Blue Top Dual Purpose Marine New in 2016 and still throw out plenty of juice. A-Jay 1 Quote
Super User Bird Posted December 30, 2019 Super User Posted December 30, 2019 Got good life out of Vmax batteries. Quote
mc6524 Posted December 30, 2019 Author Posted December 30, 2019 Thanks. I have a lot of electronics on my boat and I’m always concerned of running out of main battery power during a fishing tournament. Quote
Dirtyeggroll Posted December 30, 2019 Posted December 30, 2019 Best value = Duracell 31 AGM from Sam’s Clib Best battery = X2 31 from batteries plus 2 Quote

Electronics should be run off you cranker, not the deep cycles for your TM. You might consider a hybrid cranker or a separate battery altogether for electronics. But not your deep cycles for the TM, which is what most probably assumed you were asking about. Quote
Super User Jig Man Posted December 30, 2019 Super User Posted December 30, 2019 With modern electronics, do your self a favor and get the X2. It is the only thing I have found that will do the job. Quote
mc6524 Posted December 30, 2019 Author Posted December 30, 2019 Thank you. That’s what I thought. The Odessey battery has identical specs, but is $50.00 more. 1 hour ago, Jig Man said: With modern electronics, do your self a favor and get the X2.

That’s why I’m getting the duel purpose battery for cranking and boat electronics. Thank you 2 Quote
Super User Jig Man Posted December 30, 2019 Super User Posted December 30, 2019 There are lots of dual purpose batteries that won’t do the job the X2 will. Quote
Global Moderator Bluebasser86 Posted December 31, 2019 Global Moderator Posted December 31, 2019 I use the group 31 Duracells and have been happy with them. 3 Quote
Super User WRB Posted December 31, 2019 Super User Posted December 31, 2019 The premium marine AGM is Northstar followed by Oddessey. VMax Tank is a excellent imported battery. Optima Blue marine AGM is popular but made by Interstate a discount battery supplier. Not a fan of dual purpose batteries preferring deep cycle for trolling motors charge by home onboard chargers and cranking batteries for starting the OB and operating house electrical needs charged by the OB system. Cranking batteries have reserve amps and designed to be constantly recharged, deep cycle don't they are designed to be drained. My VMax tanks are about 10 years now still going strong. Tom Quote
DanielG Posted December 31, 2019 Posted December 31, 2019 I've got two of these agm's in my boat that Is strictly electric and runs two trolling motors and electronics for hours at a time. I recharge them at least a hundred times during the summer. I also have one in my camper. Been happy with them. they are mostly used in solar power systems. Quote
Super User NHBull Posted December 31, 2019 Super User Posted December 31, 2019 All things considered it is hard to beat the 31 vmax's. Oddessey is also very good. Quote

UPS ( universal power supply) batteries are not deep cycle marine and check the warranty if used for trolling motor / marine use. UPS AGM's are good heavy duty battery and often availble used for 1 year for around $40, check with your battery supplier. Tom Quote

Mine are going on three years and still charging well and giving good longevity during a day out. Quote

The 1 year old UPS batteries are sold as used at the low price....it means it's a good deal because they should last a least 5 years for budget minded folks. Tom Quote
22RangerZ520R Posted January 4, 2020 Posted January 4, 2020 I have (4) X2/Northstar 31 series AGM's in my boat. Love em' and have had zero issues running all my units, etc. all day long. Good luck. 1 Quote
