DO NOT BUY THIS BATTERY!!!!!!!!! THEY ARE DEKA REPLACEMENTS AND NOT DEKA!!!!!!!!! The terminals are junk and the plates unsupported so they break after a couple rides. Pure garbage and they should be sued for naming DEKA in any of their adds.

If you really want to try them, I will send the pair I bought. I keep them around to remind me to make smarter purchases.

I tried an etx-9 for a while....it doesnt work for me.

100% salt and occasional water gulps throughout the season.

I can't make any battery last more than a season or two at most anyhow. I think I land really big and flat too much and break the insides of the batteries. Some of my flat landings can be heard from 100 yards away on another running ski.

Oh and I have tried jetworks batteries. They haven't made it more than one season for me.

Battery tender is a must with small battery's. They desulfate rather quickly. I'm on year 6 on my Harley battery thanks to keeping it on a tender while not riding and off season.

I think with me it has been the WDK battery mount combined with me over tightening it. I kinda end up smashing the batt a little and maybe that is breaking something inside??

IDK...I get 2 years and game over....

I'm thinking 6lb DEKA.....
 
Before getting the ballistic , had been running Yuasa YtZ7s. It is a bullet proof battery that is 130 cca and weighs just over 4lb.

I forgot!
is that an agm or gel battery. Back when all the wallyworld 5lbs batteries where discovered and tested i got one and i think it was a sealed gel battery. It would run 45 minutes on my TL ski, then around september/oct, when tires go flat and batteries show weakness it died and would only last a few starts. I bought my buddies 2 year old deka and have had it since. I think most will agree that the deka is a great battery for watercrafts and its weight is pretty decent.

I like the solid terminals on the DEKA's as well. I would buy them over most others just to not mess around with that stupid little threaded block or weak studs like on the Odyssey's.

I have never tried a Jetworks battery simply because I do not the like the terminals.

You will not be sorry with the Deka 9...I have two going strong in 2 skis...I rarely use a $20 Schumacher automatic charger from Wally world to bump them up to maintain at least 12.62 resting volts per the multi meter ...

I guess all things can fail at some point in time. My deka had an internal short a couple summers ago. It was only a few months old. poop happens.

I agree completely. My DEKA ETX-9's have been flawless but the ETX-14 failed in just a couple months. I have had Odysseys fail in weeks and one Yuasa that lasted over 6 years. With the exception of the Yuasa, (whose lifespan I was unable to duplicate), I have never had a battery last more than 2 seasons. IMO, It's just one of those things we have to accept and pay extra attention to making sure we can take full advantage of the warranty.

I think its a crapshoot also, I have a jetworks going on 2nd or 3rd year maybe more have to check and I have a really old odyssey. for some reason that odyssey is a little weak but it just keeps going and going. its in my backup ski and I dont maintain it at all. it runs 3-4 times a year if im lucky.

I was told by the tech person years ago at odyssey that if I bought "their charger" which is better than the tender because it doesnt get stuck in charge that the battery could last 8 years or more. well I have customers who leave batteries on tenders all winter and in spring they are junk. I have put mine on the special tender and same deal. so now I feel that the only 3 things to keep a battery alive are
1)never let it discharge, always be riding the ski. disconnect it if you have a drain like a sd. but you must ride at least every other week.
2)you have to get a quality battery.
3)keep your ski tuned, cranking and cranking to get it started is probably a big contributor to premature battery death not to mention what it does to all the rest of the wiring.

now I buy agm from lynn vick, also sold by sbt locally. its the cheapest quality battery I can get locally. I wont buy acid anymore.

I also think the jetworks battery is just a better battery. But since I dont maintain mine I only keep the one in my primary ski.

Ive heard quite a few stories over the years about batteries and how to maintain them for longer life but so far have not been able to consistently keep any battery for more than a year or 2. I think the two I run now are a fluke. seems like that is supported in this thread since few have lasted the extended years the makers claim they can go.

does anyone have better experience with the tenders? I know I am lazy and lose batteries because of it, but I have gotten pissed a few times and tried to maintain a battery and usually they go a season or two and no more. I think it must have been something I did or didnt do and over time i just chalk itup to I have been lied to. is it the battery, the tender, me?
anybody able to keep batteries alive???? like multiples? multiple times? for multiple people? I just need to know if I should keep dreaming the next high dollar battery will last or quit and just figure its like trailer lights and motor mounts, replace every other season.

NEVER leave a tender connected. they all overcharge the battery.
hook it up every other week for 12 - 24 hours for the down period
and be ready to go in the spring!

OK just got the Deka today....looks and feels nice! My charger is saying F02 error though....voltage to low to accept a charge.

Is this normal? Usually I buy locally and just get handed a ready to go battery...

got a multi meter ? what's the volts now...you might have to use another charger initially if it has been discharged for some reason...they normally sit at close to 12.62 volts...
