Well just replaced my second one today. First one lasted 13 months and this one lasted 18 months. Glad I purchased them when they had the 2 year warranty!! One cell died on both of them. Is the minn kota charger I have bad for these batteries?

I have a Minn Kota on board charger. It's the best Marine charger I have ever owned. I have been thinking about trying an Optima battery but, I'm getting 24 months out of my battery's now for about half the price of what optimas cost. At the price of Optimas you should be getting Way more out of it than what you are saying. Warrenty to the rescue.
pig what batteries you using man...thats some good time.
unless they have changed a Optima battery should last you yr not months. my buddy has had the same one on his truck for yr. heck he sold the truck and keep the battery and use it for a tm battery in his boat. we was heading to lake conway to fish and he forget to tie it down and some how it flip over and sit with the terminal touching the bare metal boat floor. it melt the terminal down half way. we hooked it up to his tm and fished half the day. boat has a battle scar now.
Check battery tender web site. Ship Shape had a battery tender man talking about most people not using right charger are killing their batterys. May not be the right word but suffate builds up on plates and causes not getting a full charge. Inox, spelling may not be right, can be added and reverse and stop the build up.
13 and 18 months? I thought Optima was a high end high quality battery? I get better than 18 months on the cheap Walmart deep cycles. Somethin is not right. JMO. I have a Del Star that's 5 yrs old now and still going strong.
Deep Cycle Battery FAQ of Batteries
... cp :cool:
I use interstate mega-tron group 27 deep cycle. Going on 4 years, I have a stand alone maximiser for my trolling motor, run 3 sonars and all my led lights. I average about 3 days aweek on the water 8-10 hours a day.Very heavy use of the trolling motor. Still going stong.

I get a reading showing they are fully charged after charging (check with volt meter) but just wondering if the charger does something over time. I was very happy with them for a while but now I am not sure.
How are you testing them Scott? Using a digital meter, disconnect the charger, then wait about an hout before testing. A fully charged battery will read 12.6 volts. If you really want to do it right get one of these. 100 Amp 6 Volt/12 Volt Battery Load TesterQuote:

revtoby, I get my battery's from Battery Specialist. Heavy Duty MagnumQuote:

I was going to buy a mk dc alternator , but after doing the math you would have to run your big motor an hour to put 10 amps back to the trolling motor battery.Not worth it to me.

I think you might have something going on with your charger. If it's a good charger, it should idle down as the batt. reaches full charge so not to cause the sulfate condition talked about earlier. I have two Optima 34M in my 5th wheel and two in my boat for the 24v circuit. I get days and days on them and have had them a couple of years now. :confused:
I have 5 total optimas (3 in the crappie boat and 2 in the pontoon boat). Only two of them have gone bad, 1 from my crappie baot with the 3 bank charger and one from my pontoon with the dual bank charger. The other batteries seem to be fine.
I would like to try an optima someday. I would not consider 2 bad ones out of 5 a good thing though.
