Hi, this is quite important as I have a race tomorrow, sorry it’s short notice and I completely understand if you don’t have time to answer this. Anyways I have taken my CoxBox home to charge before the race (as usual). I plug it in and it says 46% battery, 5 mins later it’s at 100%, so I switched it on and off to double check and it goes back to 46% or lower. I need as much charge in as possible as it’s a long race, and we’ll be on the water for 2+ hours. I don’t know how to fix it! I have tried also leaving it on charge all day and night, but again the same thing happens, it goes to 100% then when taken off charge back down to 46% or less. It’s always roughly the same number it goes back down to. Sorry if it doesn’t make much sense… bit stressed!!! 🙂
That’s odd. Off the top of my head I’d say try resetting the battery but that requires more time than it sounds like you have. If you can’t borrow another cox box (which you should try to do) then you’ll just have to find a way to deal with this one. Make sure your coach and crew know ahead of time that you’re having issues with it and then plan to use it as little as possible tomorrow before the race actually starts. Once it’s in the boat just leave it off until maybe 5 minutes before your race starts. Yea, that means you’ll have to project a little more than usual but if people are quiet and paying attention it shouldn’t be much of an issue. Make sure you’re fully hydrated beforehand too since this will help keep you from losing your voice. If it stays at 46% then I’d guess you’ll get maybe an hour or so out of it, provided you don’t have the volume up super loud, so just make sure you plan accordingly.
Sorry this is a late reply and my response won’t help much in the time available.
It may need a completely new battery. But before you go there, try running down the battery completely and then recharging. Let me know what works.
Whilst I’m on this, the light bulb in my cox box has gone (okd style NK) and the uk outlet for Nk and NK repairs says that they don’t make these bulbs anymore. It’s a perfectly good cox box other than I can’t see the readings at night ( we row a lot in the dark.) Can anyone help me with a source.
Hmm, you might have to just look for another old cox box (maybe one that someone is selling for parts if it doesn’t work anymore) and take the bulb out of there to put in yours. I don’t know what kind it is specifically but if you can find out maybe you can look at home improvement stores or online to see if you can find one that way. I can’t imagine they’re NK-specific so if getting another cox box isn’t an option I’d definitely suggest looking online to see what you can find.
Thanks!!
This has happened to mine before too. Sometimes it says a low battery charge like 46%, but it is still fully charged. Also, this might be weird but blow air into the charger part that attaches to the cox box and the part of the cox box you plug the charger into. That helps a lot of the time.
Good Luck!!
