hi, always rinse them off with water immediately when done swimming and never let the battery go below a 1/4 charge. Even when storing and not using for a while, you will want to make sure to keep the battery charged. Also, they don't last for ever and if you have a local battery dealer, they can make a custom battery for you that will last longer then the factory. This is just my experience with the unit. I hope you find it useful. Tim

We have owned 8 sets over the years and find that the normal life cycle is about a year to a year and a half of daily lap swimming--which is far better than other brands we've tried. That said, we did find this model to be faulty right out of the box, and they died shortly thereafter, so we had to have them replaced, which was kind of a hassle (see my response to the first question on this list re. communicating with Finis). Overall, a year is good use for these kinds of electronics.

I believe it is probably time to get a new battery, 10 years is a long time, I replaced mine after 5 years.

that's an issue with the battery. you are gonna have to contact customer service for warranty replacement.

Yea, I noticed the same thing. I got a unit in September and a month later in October I had to replace the battery. I thought that perhaps the original unit sat on the shelf for a while and that the battery was bad. Unfortunately the weather turned for the worse since October so I have not used it since and I do not know how this next battery is going to hold up.

My battery began losing charge after 9 mo. It is now exactly 1 year since I purchased it and it runs for 20 minutes. I did the reset thing but same result.

I too have had the same problem of enlarged batteries. One did so immediately. One after a year. Both continue to work however.

I am experiencing the same problem. I thought that the batteries died. I have not replaced them yet.

my unit stopped working shortly after I acquired it. Batteries were supposed to last a year on the unit in the pool.They lasted about 10 days. Very disappointing.

you probably need new battery. when not using the dolphin for long period of time..it is better to not leave it in because it may be getting water. we had that happen before on older one we had and it was fine after that. kids didn'talways make sure the top was tight down.

Sorry for your problem with the battery install. If the new battery is not defective, sounds like the main unit is defective. I obtained the batteries as a gift for my daughter. She installed the new batteries and selected the option of new batteries installed. Then left the unit in the home dock, charging overnight. Went from running less that 5 min to completing the whole area for approx 50 min never having to go home for a recharge. Runs like new again

Try a different battery than the one that was in it and the one you replaced. If that doesn't work make certain the 2 posts are inserted as far as they will go. Now, a problem my niece had, on the wheel with all the balls. Make certain they are equally spaced. I think if the balls are to close together it throws the balance off. One wheel will turn to allow you to do this. If this doesn't correct the problem send it back to Amazon. Note: I stopped using mine because a battery only lasts about 3 months and there is no on/off switch for times when you don't want it running. It's a bother to always remove the batter.

I called the toy company this unit has not been produced for years. the only ones left are defective in some way. the toy company said the units are also very particular to the type of battery used. i returned mine.

The newest Neptune does not. I was told to rinse it and dry it after every use. When my first one stopped working after 2 weeks, that was the reason they suggested why it was not working when I plugged it into the computer (via the USB provided) but I had been consistently rinsing it in the shower with me and drying it.

I've had this for a little over two years. Battery "tests" OK, but it's hard to know how accurate that really is. In my experience all batteries test well until they suddenly stop working. I'm guessing I wouldn't get the time out of it now, that I would of gotten out of it two years ago. I will probably replace the battery in a year as preventative maintenance. I had purchased the Wayne branded battery they offer for this unit.

Sounds like a faulty unit, my last one only lasted a couple of months. It's just a cheap fun thing so I figured I would just replace them as they gave out... Since it came that way though I would say return it for a replacement.
