Looking for anyone that has used these batteries in a 24 volt system and an on-board charger/maintainer. The ProMariner Pro Sport charger has a wire to clip when used with gel pack batteries (which forces me to get a third Optima for my starting battery), but I haven't seen any discussions using these batteries with a constant charge (maintenance) charger.
Anyone have experience with this?

Big Zig I have been watching reports onm the Optima batteries and have not seen anything negative about them. So far my next set will be 2 of those for my trolling motor. BTW, they are not gel filled, they are lead acid. This came from the horses mouth. (manufacturer)

That would change everything. I read, "no spill" and assumed - should have presumed. :rolleyes:
Being acid/lead, then the maintenance mode is no longer an issue either.
Thanks, you just made my mind up.

Zig:
I don't use them in a 24 volt system but I do have two of the blue top optima batteries and this is the start of my second full year of using them.

I purchased a new Minn-Kota battery charger (portable type) and have been using it to charge up the Optima Deep Cycle Battery. This battery charger will start the charge at high voltage and then 10 amp and then drop the amps down to a trickle once the battery is fully charged. It charges in three stages. Full, Medium and then trickle charge. There is a diagram of the amp and voltage vs time on the box.

All I got to say about my blue top is that I have tried to see if I can wear it totally down but have only got as far as 50% charge on it after using it constantly for about 9 hrs of 55 l;bs thrust on about 3 all day. Then it was fully charged in less than 8 hrs. Would buy another in a minute if I could afford another one.LOL

How much do they cost each?

And just to double-check they are lead/acid and not gel, right????

That is what the manufacture said. In fact I called them today.

They use lead and an acid which is locked in a spiral bound cell technology. They can't leak unless you shoot holes in them with a rifle or something. You can lay them in any position. They are 25 times more resistant to shock than ordinary lead acid batteries. It because the lead plates are wrapped aound in a cell type structure with a fiberglass type matting in between the cells. They look like a battery made out of 6 D cell batteries put in an array of 3 x 2 and blown up in size about 10 times and coated with a hard plastic outer case.

Advanced Auto Parts is where I got my two Optima Batteries.

I paid almost 200 bucks for the blue topped Trolling motor and it was the smaller of the two deep cycle blue tops that Optima Makes. The other blue top deep cycle cost over 200 bucks but it's got more reserve capacity.

I also have a blue top Cranking Optima Battery that I use to start my boat and run the accessories like the live well pump and the cigarette lighters etc.

I can run my 50lb All Terrain Minn-Kota trolling motor all day long with the smaller of the two types of Blue Top Optima Deep cycle batteries

They are said to last twice as long as the regular lead acid batteries. If that is true I will tell you in anohter 4 years. I normally get a regular lead acid battery from Walmart to last only 3 years. These optimas should last for 6 years if the marking people are telling the truth. Only time and my testing will know the truth. If I am still around crappie.com in the next 4 years I will tell you what I found out. Hang in there

These batteries are suppose to have less internal resistance to taking a charge and therefore are said to charge up faster than a regular lead acid battery. I have found that this is true. They do charge up fast when using my old Sears Battery Charger that starts out at 10 amp and lower the amps down until the batteries are fully charged up. Then the battery charger supplies a trickle charge. I am finding that my new Minn-Kota Portable Battery charger is charging the Optima Deep Cycle up pretty quick even after I have used the battery for a long day of fishing. Remember that I fish lakes that don't allow the use of the gasoline motors so I am using the trolling motor the entire time all day long unless I anchor which I seldom to. If it's not windy I am using the Optima Deey Cycle all day long or about 8 to 10 hours at time

I have a back up battery just in chase and use a another portalbe battery charger/jumper battery to provide power for night fishing. It also will jump start my boat or truck batteries.

I recently bought a large blue top for around $180. It sure is heavy, it weighs over 60#s. So far, I like it just fine but I want to wait until about 3 years from now to pass final judgement on it.

I guess kind of where I am going with this is.....if I buy an on-board charger to use with my current batteries and I decided to buy Optima's later can I still use that on-board charger.....because one of the chargers lets you select what type battery you have ONE TIME....after that it can ONLY be used on that type of battery. So, I wouldn't want to use it on my current batteries then buy these Optima's and have my on-board charger be useless to the Optimas is they are gel or something......know what I mean?

They're lead/acid GaBoy. Your concern was mine - the only difference between a conventional deep cycle and the Optima (other then interior technology) is that they are truly maintenance free.

I'll have a set of twins in the boat by the end of the week. I'll let you know if there are any issues with the charger/maintainer. I really don't expect any at this point in time.

Yep, looks like you will be just fine.

GaBoy.. I'm going on my second year on mine. I use them with a 12/24 MG. and I used them all day yesterday and couldn't tell it. The Meter never changed. I still use the same old Wally world charger that I hard wired into the boat about five years ago, but I only leave it connected over night. They set out all winter (8 months) in the boat (covered) and this spring when I went out to check them they were both still way up into the green. Couldn't tell that they discharged any at all. I LOVE them.
Good Fishing

BigZig - You have an on-board charger for all your batteries??? What type??

That is exactly what I needed to hear....so the traditional on-board charger's such as MinnKota puts out will work fine.

I haven't bought an on-board charger yet, but you have just reassured me that since it won't be a problem then I can consider it in the near future....

Thanks for all the input from everyone!!

I use a ProSport20. It's a three bank charger/maintainer. Has the option of battery types, but like you said, it's a one time decision. I used to use a portable charger, but since I went with the on-board, I'll never go back.
Go fishing, come back, plug the boat in. Next trip, unplug boat, go fishing. Repeat as necessary.
I got tired of pulling three batteries out of the boat every winter, went with the Pro Sport and they haven't been out since.

If you are in the market - I see the newer chargers (BPS) have a selector for the different type batteries (acid vs. gel), which would elimainate a problem with the ProSport. (Of course, how often do you switch battery types?)


GABoy - I need to clarify that not all on-board chargers are maintainers. My ride sits for three-four months out of the year due to our winters. I went with an on-board that I could keep plugged in for this extended time frame. Your situation may not justify this option.

Yes, I was just wondering because I saw one at BPS that is a charger/maintainer that had a one-time selection as well and I didn't want to choose lead/acid and be stuck with that if I am eventually going to buy Optima's and they were not lead/acid. I can't stand having to keep going out and changing the charger to a new battery....I have 4 currently.....2 deep-cycle for trolling and 2 for starting....one just as a back-up.....hopefully I won't ever have to switch battery types once I get some Optimas.....
