![]() I erred!!! The Optima does NOT lose any performance when mounted in an orientation other than upright. I may have confused you when I said the Optima lose performance when mounted on its side. They are actually true deep cycle bats as well.īCP - Yes Optima batteries are AGMs specifically, lead-acid AGM as opposed to a gel AGM battery. NorthStar calls the smaller group 22 and group 24 batteries starting bats because you dont need a bat bigger than that for starting applications. *Note: all AGMs are starting batteries in the sense they are able to cough up more amps for starting applications than other battery technology. Currently being installed in mega-yachts, but you dont need to buy them by the dozen. Need a house bank on your boat? See the line of heavy-duty marine deep cycles. The LS bats are not as sensitive to the charging voltage as the Optima is, and can be bulk charged at C1 their rated capacity a 79A/Hr battery can be bulk charged at 79-amps, tho it will impact the useful life of the battery. The LS are true deep cycle bats designed specifically for trolling type applications.* If you troll every weekend and discharge the battery 100% percent every time, your Dual Pros life expectance isnt much more than 7 or 8-years. Their trolling batteries are sold under the name of Dual Pro Lightening Series. Its a new company with a new technology. If you think you like Optimas, take a look at the new AGM batteries available from the NorthStar Battery Co. Mounted sideways it loses 30% of its capacity where AGMs lose nothing and can even be mounted inverted, tho its not recommended.Almost any AGM has a better capacity, usable life, and costs less than the Optima. Penny for pound-of-performance, the Optima battery is the most expensive and shortest lived of all the batteries available. Comes down to personal preference, seems to me. The question remains whether all the nice features are worth three times the price of the regular flooded cell type. There is a constant current type of charge for conditioning, but it sounds like if the battery is getting used frequently enough this should not be necessary.Still sounds about ten times easier than any gel cell battery, and one you get used to it still quite a bit easier than the regular flooded cell type, too. They need to be topped off a lot less, actually. They self-discharge so very slowly compared to ordinary batteries there is little need to leave them on the charger all the time. I will try to sneak a peek at Optima's little 5x5 fine print card and see what surprises it might hold.I did find that these AGM batteries will recharge exceptionally rapidly but require the voltage to not be allowed to go higher than 14.2 (Concorde AGM, not necessarily Optima), and for constant charging 13.8 at a maximum of 1 amp, so current must be limited if you want to leave it on the charger all the time. I wonder what sort of charger you were using which caused all the trouble?I just found out that the Air Force uses this style battery (not necessarily Optima, though virtually identical in construction) in many/most of their fighter planes since they are safer, hold up to the stresses and strains, and last longer. there's two products in this world i absolutely dispise. !! i choose an i'll buy into the system.battery was never right. ![]() believe me, i was soooo pissed i could've punched my mother.why don't they tell ya upfront.? an why not they sell/have there own brand of optima chargers.?.!! heck, i'd buy one. finally, talked to CARL, my go-to guy at ( rhymes with US MOAT ) he deciphered the criptic script an locked me on to the 3 stage charger. ![]() that norman einstein an oppenheimer couldn't decipher. a full US CONSTITUTION wording packed on a 5x5 card. my minni-max has led battery gauge lites. they charged it an checked the new one before let me out the door, an in no-time on the water the next day lost charge. Well, that's right, they don't let ya know about the special charger ,readily.all i had was an old style charger an it ruined it pronto.
