Still trying to figure out whether or not to bite the bullet and get a couple of Optima batteries. I saw some at Sam's today---their number was 34DC, but the specs are the same as the D34M --- 750 CCA, 120 RC, 55 AH. I'm running a 70# 24v trolling motor. Is this the battery I need, or do I need the bigger one? The price is 155.82, which seems to be a really good price compared to what I'm finding elsewhere.
What you want (if you buy Optima) is the D34M (D=deep cycle and M = marine). The 34M is a marine starting battery. Both are Blue top. Look at the specs here.

the Optima SC34DM Marine has 870 marine cranking amps, 750 cold cranking amps with 120 reserve amps @ 55 Ah (amphour) and weighs 43.5# with a case size of 10 x 6.8 x 7.8"
Here is the Cabela's AGM battery with better specs and less $$ than the Optima AGM.
Cabela's Advanced Angler AGM Batteries
the size 24 has 1195 MCA, 945 CCA with 178 reserve @ 53.5 Ah and is 53.5# at 10.87 x 6.75 x 9.87......Reg: $169.99 Sale: $119.99
the size 27 has 1200 MCA, 950 CCA with 180 reserve @ 62.5 Ah and is 62.5# at 12.0 x 6.75 x 9.87......Reg: $189.99 Sale: $139.99
If you have the battery delivered, it'll cost you an extra $8. I can't drive there for that! :)
All of these are "dual purpose" batteries meaning you can use them for both starting and deep cycle use or a combination. All are large enough for your 24volt TM application.
Hope this helps......
I just bought a super start agm from oreilly's with the same reserve and a little more cranking amps than the d34m optima but $60.00 cheaper..i did sacrifice on full replacement warranty with only 9 months and a 24 month prorate but they are local and i do like to trade with the locals when i can....it's hard for me to believe that the optima is that much better than other agms on the market
Thanks for the great info. One more question on the Cabelas batteries: Statistically, there appears to be very little difference in the group 24 and group 27 batteries. It looks like the biggest difference, other than price, is the weight, and I assume one would get longer usage from more battery. Is this correct? I don't mind paying the extra 20 bucks if it will be an even better battery. Spring fishing is often windy, and I will stay out in 30 mph wind all day if necessary, so I don't want my batteries to let me down.
notice the reserve current at the higher amp hour drains. the 27 is more battery and better for deep cycle use.Quote:

Ordered Sunday evening from Cabela's and they were sitting on my porch today (Thursday). Believe it or not, we have school SATURDAY this week:eek: Gotta make up some of those snow days we missed. Oh well, probably won't have a bunch of kids show up but man I hate to have to work on a Saturday! Saturdays are for hunting and fishing!
I meant reserve MINUTES, not current! sorry 'bout dat! :oQuote:
