How to Charge your Sutro Battery



  • Amy

    I wish the 24 hours part was more clear in packaging as my husband was setting up and he is red green color blind part of why we purchased this device.  And the light readings are hard to understand when you have color blindness. We have also become accustomed to devices coming with batteries closer to ready and needing little if any charge when we buy them,  the 24 hours wwas not obvious.

    I agree.  It took forever to get here.  Not like Amazon in two days.  Now I have to wait 24 hours to do anything?  Not Happy!


  • Brian Krykewycz

    Yes. Completely agree. The labeling on the package is completely and utterly absent in my mind. It blends right in with the packaging AND... Directions on the app say zero about charging batteries before plugging in cartridge. It states to plug in extra battery to keep charged.. one would assume the battery IS charged and ready to go. Bad packaging and unclear messaging. Now apparently this is a wasted cartridge.

    Gotta say, a 24 hr charge is a bit, long? 

    I had to Google "How long do I need to charge my Sutro battery" after not getting a clear answer in setting up the device. It should be a clear warning saying "Before you Setup! Make sure your battery is has been charged for 24 Hours! If the light blinks RED it means its still charging! When it turn GREEN, it means its fully charged! Press the SYNC button inside the charge to check its status! Then, once fully charged, proceed to SET UP tutorial steps on the app!"

    Because after I open all the devices, read the manual, downloaded the app, queried around to find details, I realized it was pointless till the battery was charged. SO, put everything away, uninstalled the cartidge, put the plastic sticker back on, and waited (still now) on it to be fully charged.

    I'm sure the device will be super, its a just little joy killer is all.

    This must be made clearer in the documentation.  At least highlight how to check the status of the charging, I didn't realize I needed to push the pairing button to check the charge status until I searched the website for it.  Just making it clear would go a long way in reducing frustration.

    Agree on a few points, shipping time was very long, would have been nice to know it was going to take weeks. Second point is the cartridge should have a warning on it that it requires a full battery. Not sure if it is trash now, but will know in 24 hours when the battery is charged. Passwords are another problem, you can register on the site to buy it, but it would not accept my login on the app until I registered as new on the app as well. There are 2 apps in the store, using pro one, but not really clear which is correct. The app setup wizard was the only thing that prevented me from tossing it in the pool after loading the cartridge/low battery, at least that was okay. We setup was pretty easy.

    You definitely need to put on the packaging that it takes 24 hours to charge.  I waited and waited to head into work, thinking it had to be almost finished charging.
