Optima Battery

[warrior1]

I currently use two interstate 29 batteries for my trolling motors but one has died.  I have an opportunity to get two Optima R34m's for basically the price of one. I do fish a lot of tournaments and was wondering if the two AGM's are comparable to my 29's and will my Dual Pro 15 Amp/Bank Professional Series 3 Bank Charger be OK in charging them.

Did you mean Optima's?The red tops are an automotive starting battery. The blue tops are the trolling motor batteries

yes, sorry I meant Optima (blue tops)

Good price, but you may need to add a 3rd battery on that charger. If that’s the case you could use an extra blue top for cranking.

I am running the blue tops and have been for several years.  They are as good as any batteries that I have ever used.  I have a 250 Verado and use one for cranking also.  The ones I  had in my last boat were over 4 years old and still going strong.

I have three batteries, but my cranking is still good, so I'll wait on that one.

Optima 34m are cranking/deep cycle batteries.

 

Seems to me that for a trolling motor you'd want deep cycle only.
