    Batteries

    Anyone know of a better deal than this? $109 shipped?
    Also is it a reliable battery?

    Amazon sells Odyssey for about the same price and they are stellar batteries.

    What is most important to you? Battery price, battery reliability, battery electrical performance, longevity, safety?

    Note: Do not say price

    My advice is to only buy a top grade battery. Reliability when you are on the water is paramount.

    The only battery I can recommend is the Deka manufactured factory sealed AGM type.

    AGM batteries are far tougher than old-school lead-acid batteries.

    AGM batteries have no liquid acid to leak out, highly vibration resistant, long life, strong starting power.

    AGM batteries do not need venting and do not even have a vent tube nipple.

    AGM batteries do not self discharge during storage the way traditional batteries do. Even after sitting all winter it will typically be able to start the engine without first being recharged.

    Deka makes a high quality sealed AGM battery, identifiable by the unique red shipping caps on the post. These batteries are also sold under many other brand names, all with the same red post covers.

    The Deka battery posts are low profile and quite solid. There are two threaded bolt holes on each post. Either or both holes can beused, which can be handy for bilge pump or charging cable ring terminals. There are no nuts to drop into the hull and go missing.

    There are brass spacer rings supplied with the battery cap, these are only used for side terminal attachment if required for the cable terminal to fit properly.

    ETX16 is a common watercraft Deka battery size, but check which physical size you need to fit your model.

    Sometimes the correct AGM battery is slightly shorter than the original OEM lead-acid battery. An A suffix on the order code indicates that the battery box will include a plastic spacer piece that will match the original battery height.

    Odyssey brand powersports batteries used to have a great reputation. More recently I have been seeing reports that suggest they are no longer as wonderful as they used to be.

    I also prefer the solid Deka battery posts to the somewhat fragile Odyssey posts.

    I use these in my own machines, and have sold a couple dozen over the last 3 years with no issues yet.

    Not sure what reports you are seeing but actual users disagree with you. 4.5/5.0 star ratings from actual users is sn extremely good rating. I see nothing in these reviews that suggests that Odyssey is "fragile", as you suggest.

    I have both Odyssey and Deka AGM batteries. A little background here for those who dont know. A Polaris carbed ski needs a really strong battery, one that can deliver over 10.6 volts while cranking. My Odyssey batteries barely made this threshold. I had difficulty starting my motors. I switched to Deka and they consistently deliver more voltage while cranking the motor. So much more that i have no worries or concerns about not firing the motor. The Odyssey batteries while still ok are relegated to the skis that don't require as strong of a battery to fire them.


    Im sure the Odyssey is fine for the modern 4 strokes, but the Deka can usually be found cheaper and is a stronger battery.

    Old-school lead-acid batteries still 'work'.

    I now consider them to be ancient battery technology and prefer the better AGM battery products that are now available. AGM itself is no longer a 'new thing' as it has been proven over several decades.

    Lithium iron is the current new technology in powersports batteries. Higher cost than AGM but has its advantages.

    I was referring specifically to the metal stud posts used on Odyssey AGM batteries.

    Gotcha. I guess if you over-torque anything that small, it's possible.
